What is a Dual Layer PCB?
A dual layer PCB, also called a double-sided PCB, has two copper layers—one on the top and another on the bottom. These layers are connected by plated through-holes. This structure allows for denser routing and more components compared to single layer boards. Dual-layer PCBs strike a strong balance between simplicity and capability.
What is the Difference Between Single and Double Layer PCB?
Single layer PCBs have components and routing only on one side. They are simple, low-cost, and easier to produce. But they can be limiting in complex circuits. Dual layer PCBs, by contrast, offer routing on both sides, providing more space and better electrical performance. For example, you can separate power and signal traces better, which improves noise control and makes debugging easier.
What is the Difference Between Dual Layer PCB and 4 Layer PCB?
A dual layer PCB has two copper layers, while a 4-layer PCB includes additional inner layers, usually for power and ground. This extra space gives better EMI shielding and more routing options. But it comes at a higher cost and longer lead time. Unless the circuit requires that added complexity, dual-layer designs are often more practical for cost-sensitive applications.
What are 2-Layer PCB Design Rules?
Effective design helps avoid signal problems and manufacturing defects. For a 2-layer PCB, key rules include:
Route high-speed signals near a ground plane to reduce interference.
Use decoupling capacitors near power pins to stabilize voltage.
Ensure impedance matching for differential pairs like USB or HDMI.
Minimize vias and layer transitions to keep costs low.
Best Technology’s engineers help review your design before production to catch layout issues early. Our team uses automated DRC/DFM tools to prevent costly mistakes.
How Much Does a 2 Layer PCB Cost?
Prices depend on board size, copper thickness, surface finish, and order volume. On average, small batch prototype PCBs start at $30–$80, while larger production runs can bring per-unit cost below $1. At Best Technology, we offer cost control strategies like layout optimization, material selection (such as CEM-3), and bulk ordering for better pricing.
What is a Double Layer PCB Board Used For?
Double layer PCBs are used in a wide range of electronics. Common examples include:
Power supply modules
Lighting systems like LED drivers
Consumer electronics like smart devices
Industrial control boards
Their simplicity makes them easy to test and repair, yet they are robust enough for demanding use cases. With good layout, they can also handle moderate-speed signals and analog circuits.

Designing a reliable multilayer circuit board starts with getting the stackup right. If your project involves high-speed signals, compact layouts, or reduced EMI, an 8-layer PCB stackup is a solid choice. It offers flexibility, better performance, and room for complex routing.
In this guide, we’ll walk you through everything you need to know—layer configurations, materials, sizes, and how to make the most of this structure with the help of a trusted PCB manufacturer.
What is a PCB Stackup?
A PCB stackup is the arrangement of copper layers and insulating materials inside a circuit board. These layers are stacked and bonded together using prepreg (resin-impregnated fiberglass) and core materials. The goal is to create a reliable board that supports both mechanical strength and excellent electrical performance.
In simple words, the stackup decides how signal layers, power planes, and ground layers are placed in the board. In high-speed digital designs, this structure plays a big role in signal quality, electromagnetic compatibility (EMC), and overall performance.
For an 8-layer PCB, the stackup consists of eight layers of copper with alternating dielectric materials. These are usually divided into four signal layers and four plane layers, though that can change based on your design needs.
PCB Stackup Considerations
For most PCB designs, there are often competing requirements between electrical performance, manufacturing limitations, cost targets, and system complexity. The final PCB stackup is usually a result of careful trade-offs across these factors. High-speed digital circuits and RF systems commonly rely on multilayer boards for better control and performance. Below are 8 essential principles to consider when designing a reliable stackup:
1. Layer Arrangement
In multilayer PCBs, you’ll typically work with signal layers (S), power planes (P), and ground planes (GND). Power and ground planes are usually solid, unbroken areas that provide low-impedance return paths for signal currents. Signal layers are often positioned between these planes to form symmetrical or asymmetrical stripline structures. The top and bottom layers are mainly used for component placement and limited routing. It’s best to keep traces on these outer layers short to reduce direct radiation and EMI.
2. Defining a Single Power Reference Plane
Decoupling capacitors are vital for maintaining power integrity, and they can only be placed on the outer layers of the PCB. The trace length, pad design, and vias connected to these capacitors greatly affect their effectiveness. To improve decoupling, make these connections short and wide, and minimize via length. For example, in a high-speed digital system, place decoupling capacitors on the top layer, dedicate the second layer to power for the processor, use the third layer for signal routing, and assign the fourth layer as a ground reference.
3. Incorporating Multiple Ground Planes
Using multiple ground planes helps create low-impedance return paths and minimizes common-mode EMI. Ground and power planes should be tightly coupled, and signal layers should also be close to reference planes. Reducing the dielectric thickness between layers improves coupling and enhances performance.
4. Managing Multiple Power Planes
When your design includes more than one power plane, these planes are often split into different voltage regions. If a signal layer is placed next to a multi-region power layer, signal currents may not find clean return paths, leading to noise or EMC issues. For high-speed digital signals, avoid routing traces near split power planes to prevent return current discontinuities.
5. Designing Signal Routing Pairs
When a signal travels from one layer to another, it creates what’s known as a “routing pair.” Ideally, the return current should stay within the same reference plane when switching layers. In practice, however, signals often need to transition between layers. To maintain signal integrity, ensure that return paths are available through stitching vias or decoupling capacitors. Using adjacent layers as routing pairs is a practical and effective strategy.
6. Routing Direction Guidelines
Keep trace directions consistent within each signal layer. At the same time, rotate the routing direction between adjacent signal layers. For instance, use horizontal routing (X-axis) on one layer and vertical routing (Y-axis) on the next. This practice reduces crosstalk and improves signal clarity.
7. Even-Layer Designs is Better
Although odd-layer PCBs may appear cheaper due to fewer materials, they’re more expensive to manufacture. That’s because odd-layer boards require non-standard lamination processes and additional handling steps. These increase the risk of surface damage, incorrect etching, and longer production times. In contrast, even-layer PCBs are more stable, cost-effective, and easier to produce at scale.
8. Budget
Multilayer PCBs are naturally more expensive than single- or double-layer boards. However, they offer significant benefits in functionality, miniaturization, EMI control, and signal integrity. When weighing total cost versus performance, the difference between multilayer and simpler boards may not be as high as expected.
Standard 8-Layer PCB Stackup Structure
When it comes to multilayer PCB design, the arrangement of signal, power, and ground layers directly affects signal integrity, EMI performance, and power delivery. Below are three common 8-layer stackup configurations, each with its own strengths and limitations.
Option 1:
Layer 1: Signal 1
Layer 2: Signal 2
Layer 3: Ground
Layer 4: Signal 3
Layer 5: Signal 4
Layer 6: Power
Layer 7: Signal 5
Layer 8: Signal 6
This layout alternates signal and power layers but does not take full advantage of the electromagnetic shielding benefits that a multilayer board can offer. The ground and power planes are separated, reducing the board’s EMI suppression capability. In addition, the power distribution network suffers from higher impedance, which may affect voltage stability in high-speed or high-current applications.
Option 2:
Layer 1: Signal 1
Layer 2: Ground
Layer 3: Signal 2
Layer 4: Power
Layer 5: Ground
Layer 6: Signal 3
Layer 7: Ground
Layer 8: Signal 4
This structure is widely regarded as the optimal 8-layer PCB stackup. It provides excellent electromagnetic shielding through the use of multiple ground planes. Each signal layer is placed adjacent to a reference plane (either ground or power), which improves signal stability and impedance control. Additionally, the tight coupling between power and ground planes enhances EMI performance and power integrity. This setup is ideal for high-speed, high-frequency, or noise-sensitive applications.
Option 3:
Layer 1: Signal 1
Layer 2: Ground
Layer 3: Signal 2
Layer 4: Power
Layer 5: Ground
Layer 6: Signal 3
Layer 7: Power
Layer 8: Signal 4
This configuration is a variation of Option 1 with improved EMI performance. By adding an extra reference plane, it provides better control over the characteristic impedance of the signal layers. However, the placement of the second power plane (with limited coupling to a nearby ground) leads to higher power delivery impedance, which could be a drawback in power-sensitive designs. Some optimization in power layer arrangement is still needed.
8-Layer PCB Stackup Materials
The performance of an 8-layer PCB stackup relies heavily on the materials used between and around its copper layers. These materials affect everything from electrical behavior to thermal stability and even mechanical strength. Let’s look at the two main categories: conductive and dielectric materials.
1. Conductive Layers
Copper is the most common metal used for the conductive layers in an 8-layer PCB. It’s highly conductive, easy to work with, and available in different thicknesses and finishes.
Copper Thickness: Most boards use ½ oz or 1 oz copper per layer. If the design needs to handle higher current, 2 oz or thicker copper may be used.
Copper Type: Standard copper foil is either electrodeposited (ED) or rolled. Rolled and annealed copper is smoother and more flexible, which makes it useful in boards that need better bend resistance.
Surface Finishes: The exposed copper is usually treated with a surface finish to protect it and ensure solderability. Options include HASL, ENIG, OSP, and immersion silver, among others.
2. Dielectric Layers
The dielectric materials are the insulating layers that separate the copper traces. These layers are critical for controlling impedance, heat flow, and electrical isolation.
FR-4: A glass-reinforced epoxy laminate, FR-4 is the most common dielectric for general-purpose PCBs. It’s reliable, widely available, and cost-effective.
High-Frequency Materials: For RF and high-speed digital designs, materials with low dielectric loss—like PTFE (Teflon), ceramic-filled PTFE, or hydrocarbon-based ceramics—are preferred. These support better signal integrity at high frequencies.
Thermal Conductive Materials: When heat dissipation is a concern, substrates like alumina or aluminum nitride are used. These materials offer higher thermal conductivity than standard epoxy systems.
To hold everything together, manufacturers use prepregs—uncured fiberglass sheets soaked in resin. Common prepreg materials include FR-4 for standard designs and polyimide for higher thermal or mechanical stress environments.
At the center of the stackup is the core, which acts like a spine for the board. This rigid layer typically uses FR-4 or polyimide, though in some high-power or high-heat applications, metal cores are added to improve thermal performance.
8-Layer PCB Thickness & Sizes
The total thickness of an 8-layer PCB depends on several factors:
Copper thickness: Common values are 0.5oz, 1oz, or 2oz per layer.
Prepreg/Core thickness: Adjusted to achieve specific impedance and board height.
Number of plane vs signal layers: Affects thermal and mechanical behavior.
Common Thickness Options:
1.6mm (0.063″) – Industry standard, suitable for most applications.
2.0mm to 2.4mm – Used when extra copper is needed for higher current.
3.2mm or custom – Selected for industrial or military-grade boards.
PCB Sizes:
Panel sizes are typically 18” x 24” before routing. Your board can be as small as a few millimeters or as large as the full panel, depending on the application.
6 Layer vs 8 Layer PCB
A 6-layer PCB consists of six layers of copper circuitry stacked with insulating layers (prepreg and core) in between. It usually includes:
4 Signal Layers for routing high- and low-speed signals
1 Power Plane to distribute voltage
1 Ground Plane to provide a return path and help with EMI suppression
A typical 6-layer stackup looks like this:
Layer 1: Signal (Top)
Layer 2: Ground
Layer 3: Signal
Layer 4: Signal
Layer 5: Power
Layer 6: Signal (Bottom)
While both 6-layer and 8-layer PCBs are widely used in advanced electronics, they serve slightly different purposes depending on design complexity, signal speed, and EMI requirements. Let’s compare them together:
Aspect

Use a 6-Layer PCB if:
Your design isn’t extremely dense.
The signals don’t require tight EMI control.
You want to balance performance and cost.
There’s no strict need for multiple ground or power planes.
It’s widely used in commercial electronics that don’t involve ultra-high-speed communication or compact multilayer routing challenges.
Choose an 8-Layer PCB when:
High-speed signals (such as PCIe, USB 3.x, DDR4, or SERDES) are involved.
EMI performance is critical, especially in sensitive industrial or medical devices.
You need more space for routing due to a denser component layout.
Stable power delivery is required across multiple voltage domains.
You’re working with a compact form factor that demands vertical signal distribution.
An 8-layer stackup allows designers to pair every signal layer with a nearby ground or power plane, which significantly improves signal quality and reduces noise.

What Are PCB Stacking Connectors?
PCB stacking connectors are specialized interconnect components designed for vertically stacking multiple printed circuit boards (PCBs) to save space in compact electronic devices. They establish electrical pathways between layers while maintaining structural integrity, integrating signal pins for data transfer alongside dedicated power and ground contacts for stable current distribution.
These connectors feature precise alignment mechanisms to ensure reliable mating across stacked layers, often supporting differential pairs for high-speed protocols like PCIe or USB. Their design incorporates impedance-matched layouts to minimize signal reflections and electromagnetic interference (EMI). Mechanical stability is enhanced through locking features that prevent disconnection under vibration, with contact materials selected for durability across temperature variations. Selection depends on parameters such as stacking height adjustability, pin pitch density, and current-carrying capacity.
Application: Used in scenarios requiring bending or dynamic connections, such as foldable devices (e.g., laptop hinges), medical wearables, or robotic joints.
Selection Advice: Prioritize for low-hardness silicone or polyimide substrates to maintain signal integrity after repeated bending. Verify the minimum bending radius to avoid stress-induced damage.
2.Mezzanine Connectors
Application: Suitable for compact stacking designs like single-board computers (SBC), communication base station modules, or vertical interconnections between consumer electronics motherboards and daughterboards.

Gold fingers are one of the most critical features in many circuit boards, especially those used in high-reliability connections. Whether you’re building a test interface, designing a PCIe card, or creating an edge connector, understanding gold finger beveling and its plating design is essential for durability and smooth performance.
Let’s explore everything about PCB gold fingers, the beveling process, and how to choose the right beveling angle for your board design.
What Is a Gold Finger?
PCB gold fingers are the gold-plated connectors located along the edge of a printed circuit board. They serve as contact points when a PCB is inserted into a slot or connector, just like in RAM, GPU cards, or other modular systems. These fingers are plated with hard gold to ensure they can withstand repeated insertion and removal cycles without wearing out.
They are called “fingers” because they look like narrow, elongated pads stretching along the PCB’s edge, similar to the fingers of a hand. Each gold finger connects to a circuit trace inside the board. When the PCB is inserted into a slot, the metal contacts on the gold fingers align with the contacts inside the connector, allowing signals to pass through.
The main reason gold is used is because it doesn’t corrode easily. Gold provides high conductivity and can withstand many insertions without losing its shape or functionality. In critical environments—like military, aerospace, or telecom—this reliability is essential.
Types of Gold Fingers in PCB
PCB gold fingers can be divided into two types – graded gold fingers and staggered gold fingers.
Graded Gold Finger
Graded gold fingers refer to a design where the fingers are plated with gold at varying lengths or staggered elevations. Instead of all the fingers being aligned in a straight line, some are slightly longer than others. This is not just a visual variation—it serves a very specific purpose. Graded fingers are typically used in applications where controlled insertion sequencing is required. When the PCB is inserted into the slot, the longer fingers make contact first, followed by the shorter ones.
Staggered Gold Fingers
Another design strategy is using long and short gold fingers—also known as staggered gold fingers. This refers to gold fingers of different physical lengths on the same board edge, but typically without beveling or plating depth variation. This technique is commonly used in:
PCIe hot-pluggable cards
Industrial control systems with replaceable modules
Burn-in or test fixtures requiring safe first-contact
The lengths are designed based on the depth of the connector slot and how the PCB enters the socket. Sometimes only a few pins—such as GND or VCC—are made longer, while the rest remain short.
How Thick Is PCB Gold Finger Plating?
The durability of gold fingers comes from their plating thickness. Not all gold fingers are created equal. The thickness of the plating affects both how well they perform and how long they last.
The gold layer is not pure; it is electroplated hard gold, which includes a bit of cobalt to improve hardness and wear resistance. Here’s a breakdown of common thicknesses:
Application Type
Gold Plating Thickness (Hard Gold)
Standard Consumer Devices
0.76μm (30μin)
Industrial or Light Insertion
1.27μm (50μin)
High-Durability Applications
2.54μm (100μin)
In general, 50μin is the most common for boards that are plugged and unplugged many times. If the fingers are not meant to be removed often, thinner plating is usually fine. But when in doubt, thicker is better—it provides stronger wear resistance.
What Is the Process of Gold Plating in PCB?
Creating strong, reliable pcb gold fingers requires precision. The plating process is done after the rest of the board is fabricated and cleaned. The focus is to add a hard gold layer only to the fingers—nowhere else. Here’s how the PCB gold finger plating process works step-by-step:
1. Finger Area Isolation
First, the PCB is cleaned, and only the finger areas are exposed. The rest of the board is masked to prevent unwanted plating elsewhere.
2. Nickel Plating (Bottom layer)
A nickel layer (typically 3–6μm) is electroplated onto the copper finger base. Nickel improves gold adhesion and acts as a barrier to prevent copper from diffusing into the gold over time.
3. Gold Electroplating (Top Layer)
After nickel, a layer of hard gold is plated on top. This layer is usually between 30μin and 100μin depending on the application. The plating uses a current that drives gold ions onto the nickel surface.
4. Cleaning and Inspection
Once the plating is complete, the board is cleaned, and the gold fingers are inspected for uniformity, roughness, or any missing areas.
5. Beveling (If Required)
If beveling is needed, it is done after plating. The edge is shaped to allow easier insertion into connectors.
6. Final Finishing
The rest of the PCB receives its finish (e.g., ENIG, OSP, HASL), but gold fingers remain untouched.
This plating method results in durable, smooth connectors that resist oxidation and mechanical wear.
What Is Gold Finger Beveling?
Gold finger beveling is a mechanical process that trims the edge of the PCB—where the gold fingers are located—into a sloped angle. Rather than a blunt 90° edge, the bevel creates a smooth ramp-like surface.
Imagine sliding a PCB into a connector. A sharp edge might catch, damage the connector, or scrape off the plating. But a beveled edge slides in smoothly, reducing friction and improving contact.
This is especially useful for PCBs used in:
Backplane systems
Server racks
Communication modules
Plug-and-play components
The beveling process is typically done using precision grinding or CNC milling. Care is taken to maintain exact angle measurements without overcutting the gold plating.
Purpose of Gold Finger Beveling
There are several important reasons why beveling is applied to PCB gold fingers:
Easier Insertion
A beveled edge helps the PCB slide into the connector smoothly. It reduces the chance of misalignment or jamming.
Prevents Contact Damage
Without beveling, the sharp PCB edge can scratch the connector pins, causing early wear or performance issues.
Reduces Wear and Tear
Repeated insertion cycles can wear out the gold plating. Beveling distributes the pressure more evenly, extending the lifespan of both board and connector.
Better Electrical Contact
Smoother insertion means better alignment and tighter contact with the metal pins inside the slot. This leads to more stable signals and fewer connection errors.
Professional Manufacturing Finish
Beveled gold fingers look more refined, signaling high-quality PCB craftsmanship.
For any board that’s going to be removed and reinserted frequently, beveling is not just a good idea—it’s almost essential.
Gold Finger Beveling Angle Options
When beveling, you have options for the bevel angle. The choice depends on how the PCB fits into its slot and the degree of insertion force you want to reduce. Here are the common beveling angles:
Angle
Description
30°
The most popular angle. Balances mechanical strength and ease of insertion.
40°
Offers a smoother slope than 30°. Used when insertion needs to be gentle.
45°
The steepest slope. Useful when the board must glide into the slot with minimal resistance.
Most applications stick with 30°, but you should always check the connector specification. Some high-density or high-speed connectors might require tighter tolerances and smoother entry paths.
Considerations of Beveling Angles
Before you finalize your beveling angle, consider the following:
Slot Geometry
Look at how your connector or socket is shaped. If the slot opening is narrow, a steeper bevel (like 45°) might be helpful.
Insertion Frequency
If the PCB will be removed often—like in test or modular setups—a smoother entry reduces long-term damage.
Mechanical Strength
Sharper bevels remove more material. If your board edge carries mechanical load, avoid overly steep bevels.
Gold Coverage
The beveling process should never cut through the gold. Make sure the gold plating thickness is enough to cover the entire bevel.
IPC Guidelines
Refer to IPC-6012 and IPC-A-600 for guidelines on gold finger design, plating, and beveling requirements.
Always coordinate with your PCB manufacturer to ensure the chosen bevel angle is feasible and matches your product’s functional needs.
PCB Gold Fingers Applications
Gold fingers are everywhere. Any device that uses edge connectors likely has them. Some of the most common use cases include:
Graphics cards (GPU) – for connecting with the motherboard
RAM modules – inserted into DIMM slots
Motherboards and backplanes – for communication between layers or devices
Test interface boards – for burn-in, programming, or debugging
PLC and industrial control systems – for module plug-in
Medical and defense electronics – where reliability is critical
In all these applications, gold finger beveling helps ensure the boards don’t fail during connection or removal. It may seem like a small detail, but its effect on reliability is huge. Gold finger beveling is one of those small but powerful features that improves the mechanical fit, electrical contact, and overall durability of your circuit boards. When designing your next PCB, pay attention to:
The gold finger plating thickness
Whether beveling is needed
The best angle for smooth insertion
And the wear-and-tear the board will experience
These decisions affect not only how well the board works, but how long it lasts.
