How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

April 9th, 2025

What Is a Gold Finger in PCB?

PCB gold finger is a row of gold-plated conductive contact sheets located on the edge of the printed circuit board, named for its shape like a finger and plated with gold. It is usually used to insert the PCB into a connector or card slot for electrical connection and signal transmission. You’ll often find them on expansion cards, memory modules, and interface boards that plug into the motherboard or backplane.

These fingers act as the physical and electrical contact points between the PCB and its slot. They need to be durable, conductive and corrosion-resistant, which is why gold is used. Unlike standard wires or padding, gold fingers must withstand repeated insertion and removal, so wear resistance and high reliability are top priority in their design.

How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

What Material is Gold Fingers Made of?

Gold fingers aren’t pure gold, and they don’t need to be. Instead, they are a multi-layer structure designed for performance, not cost.

At the core is copper, the base layer used in nearly all PCBs. Copper offers excellent electrical conductivity. But copper oxidizes over time, which affects signal transmission. So, a nickel barrier is added next. Nickel prevents the copper from diffusing into the top gold layer and adds hardness.

Finally, a thin layer of gold—either hard electroplated gold or soft immersion gold—is applied on top. Gold is chosen for two key reasons: it’s a great conductor and it doesn’t tarnish or corrode. This ensures long-lasting, high-performance edge connectors.

The amount and type of gold used depend on the application. Some fingers will have a thicker, harder gold layer for high-wear use. Others, used less often, may use thinner or softer gold to save on cost.

Types of PCB Gold Fingers

1. Standard PCB Gold Fingers – The most common PCB gold fingers, with horizontal and even arrays. PCB pads have the same length, width and space. This type of gold finger is easy to make.

How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

2. Uneven PCB Gold Fingers – PCB pads have the same width but different lengths and sometimes different spaces like below image showing. For some PCBs, the gold fingers are designed to be shorter than others. The most relevant example of such PCBs is a PCB for a memory card reader, where the device connected to the long finger must first power the device connected to the shorter finger.

How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

3. Segmented PCB Gold Fingers – PCB pads have different lengths, and the gold fingers are segmented. Segmented gold fingers vary in length, and some of them are also disjointed within the same finger of the same PCB. Such PCBs are suitable for waterproof and rugged electronics.

How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

PCB Gold Fingers Manufacture Technical

Not all gold fingers are made using the same process. The method and material used for gold plating affect the performance, durability, and cost of the final product. Let’s take a closer look at the most common types.

Electroless Nickel Immersion Gold (ENIG)

ENIG is a chemical process used to deposit a thin, even layer of gold over a nickel base. It’s not applied using electricity, so it creates a smooth, flat surface. ENIG is known for its excellent surface planarity and is commonly used for surface mount pads. But in gold fingers, it’s less common unless the board will be inserted only a few times. ENIG produces softer gold, which means the plating wears off faster with repeated use.

Electroplated Hard Gold

This is the most popular choice for gold fingers PCB applications. Electroplating uses an electric current to apply a thicker and harder layer of gold, its gold thickness can be up to 50u’’. Hard gold plating usually includes small amounts of cobalt or nickel, which makes the gold layer more rigid. This helps it resist abrasion during multiple insertions into card-edge connectors.

Electroplated hard gold is a bit more expensive than ENIG but lasts longer and offers better performance for edge connectors.

Edge Beveling

Edge beveling isn’t a type of plating but an additional mechanical step. It involves cutting or grinding the PCB edge at an angle, typically 30° or 45°, to make insertion into connectors smoother.

Beveled edges help prevent damage to both the PCB and the mating socket. It also reduces insertion force, minimizing wear and tear. While beveling isn’t mandatory, it’s often recommended when the board will be inserted and removed multiple times.

Gold Fingers vs. Edge Connectors

“Gold fingers” and “edge connectors” are both terms used in PCB design, but they refer to slightly different concepts. Gold fingers are part of the PCB, while edge connectors are part of the device that receives the PCB. Gold fingers are the gold-plated pads at the board’s edge. They’re designed to slide into the slot of an edge connector. The connector itself is usually mounted on a motherboard or backplane, holding the PCB in place and ensuring a stable electrical link.

FeatureGold FingersEdge Connectors
DefinitionGold-plated contact pads on the edge of a PCBSocket or slot that receives the PCB
LocationPart of the PCB itselfMounted on a motherboard or host board
FunctionTransmit signals and power from PCB to systemProvide physical and electrical connection
MaterialCopper + nickel + gold platingUsually plastic body with internal metal contacts

Customization  Length, width, plating, beveling can be customizedUsually standard depending on slot type
Common UseRAM sticks, GPU boards, industrial control boardsMotherboards, expansion slots, backplanes
Design ConsiderationNeeds precise layout, spacing, and gold platingMust match PCB layout and dimensions

Benefits of Designing Gold Fingers at the Edge of PCB

  1. Gold fingers allow boards to be plugged directly into other systems without the need for extra connectors, makes design simpler and install faster.
  2. Gold is highly conductive, so the signals and power of devices enable to pass efficiently through the interface. They are often used in high-frequency or high-speed data applications.
  3. Gold does not oxidize or corrode. Even in moist or harsh environments, it maintains its performance over time.
  4. Hard gold plating can handle thousands of insertions without degrading. That’s why it’s ideal for modular designs or devices that get frequently unplugged.
  5. Gold fingers reduce the need for bulky connectors, allowing for more compact PCB designs—especially valuable in smartphones, wearables, and compact industrial modules.

How Thick Is a PCB Gold Finger?

The gold thickness on fingers typically ranges from 3 to 50u’’, depending on how the PCB will be used. For commercial and industrial use, the standard is usually 30u’’ of hard gold over 100–150u’’ of nickel.

  • 3–10u’’: Suitable for low-cost applications with minimal wear.
  • 15–30u’’: Common for most consumer electronics and industrial devices.
  • 45–50u’’: Used in military or high-end industrial equipment that needs maximum durability.

PCB Gold Finger Plating Process

The hard gold plating process for PCB gold fingers involves several precise and carefully controlled steps. Here’s how it’s done:

1) Apply Blue Protective Mask

All areas of the PCB surface except the gold finger pads are covered with a blue protective mask. This ensures that only the contact pads receive hard gold plating. The conductive areas are aligned consistently with the board’s orientation to maintain plating accuracy.

2) Remove Oxide Layer from Copper Pads

Next, the oxidation layer on the copper surface of the gold finger pads is removed. We use sulfuric acid for this step, followed by a water rinse. Then, the surface is mechanically scrubbed to ensure it’s fully clean. After that, we rinse the surface again using water and deionized water to eliminate any residues.

3) Electroplate Nickel onto Copper Pads

A nickel layer is then electroplated onto the clean copper surface of the gold finger pads. This layer serves as a barrier and bonding surface for the gold. After plating, the surface is thoroughly rinsed again with water and deionized water to remove any remaining nickel solution.

4) Electroplate Hard Gold over Nickel

Now comes the hard gold plating step. A layer of gold is electroplated onto the nickel-coated pads. This provides durability, conductivity, and wear resistance. Any unused gold solution is recovered for reuse. Finally, the plated area is cleaned again—first with water, then with deionized water—to ensure a spotless surface.

5) Remove Blue Mask

With the hard gold plating complete, the blue protective mask is removed. The PCB is then ready to move forward in the manufacturing process, beginning with the solder mask printing step.

Design for Manufacturability (DFM) of PCB Gold Fingers

1. Beveling Design for Gold Fingers

  • The safe distance between the gold fingers and the PCB outline edge must be considered. This depends on the final board thickness and the bevel angle. Common bevel angles are 45o.
  • If the gold fingers are too close to the board edge, copper may be exposed during beveling. To avoid this, copper should be trimmed based on specific parameters as below. However, if you do not want to shorten the gold fingers, increase the safety distance between them and the board edge as per the recommended values.
Bevel AngleBoard Thickness (mm)Remaining Thickness (mm)Beveling Depth (mm)
  20o1.60.51.51
3.00.651.85
2.50.72.47
    30o1.00.50.44
1.20.50.60
1.60.50.95
2.00.651.16
2.50.71.56
    45o1.00.50.25
1.20.50.35
1.60.50.55
2.00.650.68
2.50.70.9

2. Solder Mask Opening Design

  • To ensure easy insertion into connectors, no solder mask should be applied over the gold finger area. Full openings must be designed here. If the area is not fully opened, solder mask ink between gold fingers can peel off after repeated insertion/removal, which may affect contact reliability.
  • Gold finger and tin finger areas must have solder mask openings that extend approximately 10 mil beyond the board edge.
  • The solder mask opening should be 4 mil larger than the trace on each side. Make sure that the distance between the opening and surrounding copper is safe to prevent exposed copper. If copper is exposed, it must be removed (etched).
  • No solder mask opening is allowed for vias within 2 mm of the gold finger area.

3. Copper Pour Design on the Signal Layer

To support smoother insertion, avoid copper pour (flooding) in the gold finger region on the outer layers. If multiple fingers share the same net and copper is poured, they might be joined into a single pad, which affects mechanical separation and may interfere with insertion/removal.

How to Design PCB Gold Fingers? PCB Gold Finger Plating Process

4. Uneven Gold Fingers

  • For uneven gold fingers, the main trace should be 40mils, and the auxiliary trace should be 20mils. The connecting point should be 6mils, and the distance between the pad and the 20mil auxiliary trace should be 8mils. After adding the staggered traces, the main trace should be shifted to maintain an 8mil spacing from the long finger pad.
  • When the main trace enters the board, it should be connected using a diagonal line. If there’s a large groove beside the finger, the trace should be curved, not angled.

How Are PCB Gold Fingers Used?

Gold fingers are found in a wide variety of applications across many industries:

  • Computers: RAM modules, GPUs, and expansion cards all use gold fingers to connect to the motherboard.
  • Consumer Electronics: Devices like game consoles, smart TVs, and wearables use gold fingers for modular connections.
  • Medical Devices: Equipment requiring high reliability often includes gold fingers for secure signal transfer.
  • Industrial Automation: Boards that plug into PLCs or backplanes use gold fingers to keep connections stable in harsh environments.
  • Aerospace and Defense: Mission-critical systems rely on hard gold fingers for consistent performance and durability.

FAQs

1. What’s the Ideal Thickness for PCB Gold Fingers?

    Most designs use 30ÎŒin of hard gold.

    2. Are Gold Fingers Always Beveled?

    Not always, but beveling helps reduce insertion wear. It’s recommended if the board is plugged in and out often.

    3. How Do I Know If I Need ENIG or Hard Gold?

    Use ENIG for light-use connectors or where solderability matters. Go for hard gold when durability and frequent insertions are key.

    4. How Much Does PCB Gold Fingers Cost?

    PCB gold fingers cost depends on gold thickness, finger length, and quantity. Thicker gold and more fingers increase cost, but also improve lifespan. Contact Best Technology to get a quotation.

    5. Can Gold Fingers Be Repaired?

    Usually, no. Once worn or damaged, the board often needs to be replaced.

    What is a prototype PCB?

    A prototype PCB is an early version of a printed circuit board. It’s made in small quantity to test the design. Engineers use it to check connections, components, and layout. It’s also useful to test heat performance and real-life function. Before investing in mass production, this board helps catch errors. If changes are needed, it’s cheaper and easier to do it early. Many companies even make two or three versions before finalizing the product.

    Prototypes can be basic or complex. Some are simple boards with no parts added. Others are fully assembled with all components. Both types are valuable depending on the project. The goal is to verify function and remove issues early.

    How to make PCB prototyping?

    The first step is creating a design. Software like Altium, KiCad, or Eagle helps engineers draw the layout. Next, you generate Gerber files. These files tell the factory how to build the board.

    Once the design is ready, fabrication begins. A copper layer is placed on a base material. Then, the image of your circuit is transferred onto the copper. Unwanted copper is etched away, leaving your circuit traces. After this, holes are drilled and plated. These connect different layers of the board.

    A solder mask is applied next. It protects the copper and gives the board its green or blue color. Labels are printed using silkscreen. At last, components are added to build a working sample. Testing follows to ensure the board works well.

    How is a PCB manufactured?

    The process of full PCB manufacturing includes these steps:

    • Material selection: FR4, aluminum, ceramic, or flexible base
    • Laminating copper: Pressing copper onto the base
    • Imaging: Circuit layout is printed with UV light
    • Etching: Removing extra copper, keeping circuit paths
    • Drilling: Making holes for vias and components
    • Plating: Coating the holes to connect layers
    • Solder mask: Protecting traces from damage
    • Surface finish: Adding HASL, ENIG, or other finishes for better soldering
    • Silkscreen: Adding part labels, logos, and marks
    • Testing: Electrical and visual checks to ensure no faults

    This entire process can take from a few hours to several days. It depends on the board’s complexity and quantity. The goal is to create a reliable board that works just like the prototype.

    PCB Prototype Manufacturing Service

    How much does a PCB prototype cost?

    Cost depends on many factors. These include board size, number of layers, materials, and surface finish. For example, a simple two-layer board might cost $10 to $50 for a small run. A complex six-layer board might go up to $200 or more. If you choose special materials like aluminum or Rogers, prices go even higher.

    Other cost factors include:

    • Fast turnaround time
    • Number of boards ordered
    • Assembly service (adding components)
    • Shipping fees

    To save money, order multiple boards or plan ahead to avoid rush fees. Working with a trusted manufacturer helps reduce hidden costs too. Always check the full quote before ordering.

    1. Cost Reduction

    By optimizing the design, you can reduce waste, material usage, and labor. Simple shapes, fewer parts, and efficient processes lead to lower costs.

    2. Faster Production

    Well-designed parts are easier to manufacture. This leads to shorter cycle times and quicker delivery. Less rework and fewer changes speed things up too.

    3. Improved Product Quality

    DFM encourages consistency. It minimizes variation and errors during production. As a result, you get a higher-quality end product that performs reliably.

    Perform DFM before manufacturing can detect potential defectives that we can’t detect, it covers three aspects, including:

    Free Design for Manufacturing DFM Support, DFM vs. DFMA

    What are the 5 Principles of Design for Manufacturability?

    1. Reduce the number of parts/components

      By simplifying the design, reducing the number of parts can reduce manufacturing costs and complexity and improve production efficiency. For example, combining multiple parts into one not only reduces the chance of errors, but also saves assembly time and development time.

      2. Standardized design

      The use of standardized components and design elements helps to reduce production variability and improve product consistency. Standardized design can reduce design time, improve assembly efficiency, and reduce research and development costs.

      3. Simplify the assembly process

      Considering the convenience of assembly during design can reduce assembly time and cost. Through modular design, the same set of parts can be used alternately, reducing the dependence on specific molds, thereby reducing production costs.

      4. Material selection

      Select the appropriate material to ensure the manufacturability and performance of the product. Reasonable material selection can not only improve product reliability, but also reduce manufacturing costs.

      5. Manufacturing tolerances

      Reasonably set manufacturing tolerances to balance manufacturing costs and product quality. Proper tolerance setting can ensure product quality and reduce production costs at the same time.

      What is the Difference Between DFM and DFMA?

      It’s easy to mix up DFM and DFMA. They’re closely related but serve slightly different purposes.

      DFM (Design for Manufacturing) focuses on manufacturing, refers to the design for manufacturing, mainly focuses on how to simplify the parts processing process through design, reduce the difficulty and cost of manufacturing. Its core goal is to optimize designs and make them easier to manufacture while improving product quality. DFM‌ focuses on parts processing, reducing manufacturing difficulties through design optimization, such as reducing complex processes and avoiding strict tolerances.

      DFMA (Design for Manufacture and Assembly) combines the principles of DFM and DFA (Design for Assembly) to optimize the manufacturing and assembly process of products to reduce costs, increase efficiency and improve product quality. DFMA‌ not only focuses on manufacturing, but also on assembly, emphasizing the comprehensive consideration of manufacturing and assembly optimization in the design stage, such as reducing the number of parts, simplifying the assembly process, etc.

      In short:

      DFM = Can we make this part easily?

      DFMA = Can we make and assemble this product easily?

      Common Defective Issues Detected by DFM

      Common Defective Issues Detected by DFM

      How to Perform Design for Manufacturing DFM?

      Performing DFM is not a one-step process. It’s a mindset that should be part of every stage of product development.

      1. Engage Early with Manufacturers

      Bring in manufacturing experts during the design phase. Their insights help prevent rework and delays later.

      2. Evaluate the Design for Each Process

      Check if the design works well with cutting, forming, molding, or other methods. Each process has its strengths and limits.

      3. Reduce Part Counts

      Combine parts where possible. Fewer parts mean fewer connections, less inventory, and easier builds.

      4. Analyze Tolerances

      Use realistic tolerances. Too-tight specs increase cost and difficulty. Focus on where precision is truly needed.

      5. Review Materials and Finishes

      Pick materials that are easy to source and suitable for the environment. Avoid special coatings unless they’re vital.

      6. Prototype and Test

      Use early builds to check for problems. Make improvements based on real data, not just models. DFM is about iteration. Keep refining until the design fits both function and production.

      What Should You Consider When Designing for Manufacture?

      When designing for manufacturing, many small details matter. These are the key areas to watch:

      • Avoid complexity design. Keep PCB simple and easy to shape.
      • Design parts that work well with available tools. Custom fixtures can slow things down.
      • Think about how the part will be handled. Can it be picked up, rotated, and fixed easily?
      • Check how tolerances from one part affect the whole system. Misalignment can come from small errors that add up.
      • Use materials that match the product’s goals—strength, weight, heat resistance—but also consider cost and ease of use.
      • Don’t ask for polished surfaces unless needed. Extra finishing steps raise cost and time.
      • Are the parts easy to source? If not, you may face delays or searching for alternative parts.
      • High-volume parts benefit from different methods than low-volume ones. Tailor your design to the production level.

      What is the Meaning of PCBA? PCBA Process

      April 8th, 2025

      What Does the PCBA Stand For?

      PCBA stands for Printed Circuit Board Assembly.

      It’s a complete board where all parts are mounted and ready to work. The bare board itself is called a PCB. But once components like resistors, capacitors, and chips are soldered onto it, it becomes a PCBA. Sometimes, some electronic accessories will be soldered onto the PCB surface as well.

      What is the Meaning of PCBA? PCBA Process

      Key Components in PCBA

      The value of a PCBA comes from the components it carries. Each part plays a role in how the circuit works. Let’s go over some of the most common parts:

      • Resistors: Control the flow of current.
      • Capacitors: Store and release energy when needed.
      • Inductors: Manage signals, especially in filters.
      • Diodes: Let current flow in one direction only.
      • Transistors: Switch or amplify signals.
      • ICs (Integrated Circuits): Small chips with many tiny parts inside. They perform complex functions.
      • Connectors: Help connect the board with other systems.
      • Transformers: Change voltage levels for safer or better operation.
      What is the Meaning of PCBA? PCBA Process

      All these parts must be carefully chosen and placed. A small mistake can stop the board from working right. That’s why design and assembly matter so much.

      Types of PCBA Assembly Techniques

      1. Surface Mount Technology (SMT)

      This is the most common method today. Components are placed directly on the surface of the board. Pick and place machines handle most of the work, which keeps it fast and accurate. SMT supports miniaturized parts and high-speed production.

      2. Through-Hole Technology (THT)

      This technique uses components with leads that go through holes in the PCB. These leads are soldered on the other side. THT is strong and used for large or high-stress parts like connectors or transformers.

      3. Mixed Technology Assembly

      Some boards use both SMT and THT. Surface-mount parts go on first, then through-hole components are added by manually. This mix allows for flexible, compact, and reliable designs.

      What is the difference in PCB and PCBA?

      Though the terms PCB and PCBA are often used together, they describe very different stages in the electronics manufacturing process. And you must to know: PCB are one of important part of PCBA, but PCBA not. Below we listing the key differences between them:

      FactorPCBPCBA
      StageBlank boardAssembled with components
      ComponentsNoYES
      FunctionalityNon-functionalFully operational
      Manufacturing CostLowHigher (because include the components cost)
      TestingBasic inspectionComplete electrical testing
      Assembly TechniquesNot applicableSMT, THT, or hybrid
      Files NeededGerber, drill filesGerber, BOM, pick & place, assembly files
      Lead Time (under same design)ShortRelated longer than PCB

      What Is the Use of PCBA?

      PCBAs are used in almost everything you see around:

      • Phones: Control your screen, camera, and sound.
      • Computers: Process data, run programs.
      • Vehicles: Support GPS, safety features, engine control.
      • Medical devices: Power equipment like MRI or ECG machines.
      • Home appliances: From smart TVs to microwave ovens.

      Without a PCBA, none of these would work. It’s like the brain of any electronic device. From simple tools to high-end gadgets, PCBA plays a big role.

      How to Do PCBA Testing?

      Testing makes sure the board works as expected. It helps catch issues before the board goes into the final product. There are several ways to test a PCBA:

      1. Visual Inspection

      This is the first step. Technicians or machines check if parts are in the right place. They also look for bad solder joints, cracks, or missing items.

      2. Automated Optical Inspection (AOI)

      AOI mainly uses a camera system scans the board. It checks for incorrect or misaligned parts. It’s faster than manual inspection and works well for large batches.

      3. In-Circuit Testing (ICT)

      ICT checks each component directly. It makes sure resistors, capacitors, and connections work properly.

      4. Functional Testing

      This test powers the board and simulates how it will be used. It checks whether the PCBA can perform the expected tasks.

      5. X-Ray Inspection

      Used when components are hard to see, like BGAs (Ball Grid Arrays). The X-ray looks through the board to catch hidden problems.

      6. Flying Probe Test

      For small batches, probes test different points without a custom fixture. It’s flexible and cost-effective.

      7. Testing with jig

      This is used for mass production, jig tools are made according to the design files, so it is a customized. Jig testing can save much time compared with flying probe.

      Best Technology deeply know the importance of the product quality, so we pay more attention to the PCB board quality checking process. We set a QC department according to ISO9001:2015 and ensure all processes are compliance with quality system.

      How Do You Clean a PCBA?

      During the PCB assembly process, cleaning a PCBA is an important step, especially after soldering. Residual flux, dust, or moisture can affect the performance of the board. Nowadays, the common cleaning methods used in Best Technology are:

      1. Manual Cleaning

      This is the most basic method. A technician uses a soft anti-static brush and high-purity isopropyl alcohol to remove visible flux or dirt. It’s ideal for prototypes, small batches, or after rework or repair. Manual cleaning gives the operator control, especially in tight or delicate areas. However, it’s time-consuming and not suitable for large-scale production.

      What is the Meaning of PCBA? PCBA Process

      2. Ultrasonic Cleaning

      Ultrasonic cleaning is widely used for complex boards and mass production. The PCBA is submerged in a tank filled with a cleaning solution. High-frequency sound waves pass through the liquid, creating microscopic bubbles. These bubbles collapse rapidly, producing a scrubbing action known as cavitation.

      This technique reaches tiny gaps under components where brushes can’t go. It’s very effective for removing dried flux, fine dust, or ionic contamination. The process is gentle on components but powerful enough to clean even the most compact assemblies. After cleaning, the board is rinsed and dried with warm air or placed in a drying chamber.

      What is the Meaning of PCBA? PCBA Process

      3. Dry Ice Cleaning

      Dry ice cleaning is a newer, eco-friendly technique. It uses solid CO₂ pellets, also called dry ice, blasted at high speed onto the PCBA surface. As the pellets hit, they turn into gas instantly. This process lifts off dirt, flux, and even adhesives without leaving moisture or residue behind.

      What is the Meaning of PCBA? PCBA Process

      Dry ice cleaning works well for delicate electronics and is especially useful in industries where cleanliness must meet strict standards. To give customer a highest quality of the PCBA, our SMT factory equipped with the dry ice cleaning machine to ensure a clear surface while improve the efficiency.

      PCBA Assembly Process

      The PCBA assembly process is relatively simple than PCB manufacturing, actually the most tedious step is to load all the components on the pick and place machine, and set the program parameters. Here we break down all the processes of the mass production PCB assembly, from the solder paste printing to function testing.

      1. Solder Paste Printing

      First, solder paste is applied to the bare PCB. This paste is mainly consists of silver and tin, a mix of tiny solder particles and flux. A stencil is placed over the board, and the paste is spread across it using a squeegee. The paste sticks only to the exposed pads where components will be mounted.

      2. Load components feeder

      Load all the components in the feeder of the pick and place machines, make sure all the parameter of components are correct, and double check the direction of chips. It is a simple but tedious step and need much time to check everything is okay. 

      2. Pick and Place

      After applying solder paste, automated pick-and-place machines begin placing surface-mount components onto the board. These machines work fast and accurately. They follow a file created during PCB design that tells them the exact location for each part. The components sit on the solder paste, which holds them in place temporarily.

      3. Reflow Soldering

      Next, the assembled board goes through a reflow oven. The oven slowly heats the board in stages. When it reaches a high enough temperature, the solder paste melts and forms strong electrical and mechanical connections between the parts and the board. After this, the board cools down, and the solder solidifies.

      This step is only for SMT components. If the board has only through-hole parts, this step may be skipped.

      4. Inspection (AOI and Visual)

      Once the soldering is done, the board goes through inspection. Automatic Optical Inspection (AOI) machines scan the board using high-resolution cameras. They check for misaligned parts, soldering problems, or missing components. For small production or sensitive areas, manual inspection is also performed to catch anything machines might miss.

      5. Through-Hole Component Insertion (If Needed)

      If the board uses through-hole technology (THT), this is when those parts are added. Workers or machines insert the components into the holes, and the leads go through to the other side of the board. These components are often bulkier, like connectors or transformers.

      6. Wave Soldering (For THT)

      For boards with many through-hole parts, wave soldering is used. The board passes over a wave of molten solder that touches the underside. This solders all the leads at once. It’s fast and effective, especially for high-volume production. For small-scale or sensitive boards, hand soldering might be used instead.

      7. Final Inspection and Quality Control

      After soldering, the entire board is checked again. Technicians or AOI machines inspect the final assembly. They look for cold joints, excess solder, or misplaced parts. Boards may also be tested with X-ray machines to inspect solder joints under BGAs or hidden areas.

      8. Functional Testing (FCT)

      The next step is functional testing. The board is powered up and tested to make sure it works correctly. This could include checking voltages, signals, response times, and communication with other devices. Engineers may use test jigs or test programs based on the end application.

      9. Cleaning (If Needed)

      After all soldering and testing, the board might be cleaned to remove flux residue. Depending on the flux used, this could be manual, ultrasonic, or dry ice cleaning. Clean boards are especially important in high-reliability fields like aerospace, automotive, or medical.

      10. Conformal Coating or Protection (Optional)

      For some applications, a conformal coating is applied. This is a protective layer that shields the board from moisture, dust, and chemicals. It’s often used in harsh environments. Coating can be applied by spraying, dipping, or brushing.

      11. Packaging and Shipping

      Finally, once the PCBA passes all checks, it’s packed carefully. Anti-static bags, foam, and trays protect it during transport. Labels are added for tracking and traceability. From here, it’s ready to be installed into the final product. Here is a whole process of pcb assembly in Best Technology.

      PCBA HS Code

      Every product for trade needs a code. The HS code for PCBA usually is 8517799000

      But depending on the use or market, some customs may use a different classification. For example:

      853400 for bare board parts, sometimes be used on certain assembled parts.

      847330 for boards used in computers.

      853710 for board which used as controller or controller unit.

      Noted: Always check with your country’s customs for the right code. Using the wrong one may cause delays or extra costs.
