What is a Double-Sided PCB?
A double-sided PCB is also called a double-layer PCB. It has copper traces on both sides connected through vias, allowing component placement on either surface. As a cost-effective solution between single-sided and multilayer PCBs, it provides 60% higher wiring density than single-layer boards. These PCBs are widely used in consumer electronics (e.g., smartphone motherboards), automotive controls, and industrial automation systems, balancing performance and manufacturing costs.
How Are Double-Sided PCBs Manufactured?
Double-sided PCB manufacturers follow a series of precise and professional steps to produce reliable circuit boards. At Best Technology, we use a proven process designed to ensure performance, quality, and consistency. Here’s how we do it:
1. CAM Engineering Processing
- It all starts with careful design file preparation. Our CAM engineers review Gerber files, optimize them, and ensure everything is ready for manufacturing. They prepare the data used throughout the production line.
2. Drilling (Mechanical or Laser Drilling)
- Next, we drill holes for vias and through-hole components. Depending on the design, we use either mechanical drills or laser drilling methods. This step lays the foundation for reliable connections between the two copper layers.
3. Hole Metallization (Chemical Copper Plating → Electroplating)
- Once drilling is done, we chemically deposit a thin layer of copper inside the holes. This is followed by electroplating to thicken the copper, which creates conductive paths between layers.
4. Outer Layer Pattern Imaging (Lamination → Exposure → Developing)
- Here, we apply a photosensitive dry film on the board and expose it to UV light through a photo-tool. After developing, the unexposed areas are removed, revealing the copper that will form the final circuit pattern.
5. Pattern Plating (Copper + Tin)
- We then plate the exposed copper with a thicker layer of copper, followed by a tin layer to protect it during the next etching step. This builds up the conductive traces to the right thickness.
6. Etching (Film Removal → Etching → Tin Stripping)
- After plating, we strip off the photoresist. Then we etch away the unwanted copper. The tin layer acts as a barrier and is later removed, leaving behind clean copper traces.
7. Solder Mask Application (Coating → Exposure → Developing)
- We apply a green solder mask to protect the copper circuitry. The board is exposed again to define areas where components will be soldered, then developed to wash away the excess.
8. Surface Finishing (ENIG, HASL, OSP, etc.)
- Now it’s time for surface treatment. We apply finishes like ENIG (Electroless Nickel Immersion Gold), HASL (Hot Air Solder Leveling), or OSP (Organic Solderability Preservative). These enhance solderability and prevent oxidation.
9. Mechanical Profiling (Routing/V-Cut/Punching)
- Boards are shaped and separated using different techniques like milling, V-cutting, or punching. This step ensures the board fits perfectly into its final application.
10. Electrical Testing & Final Inspection (AOI/Flying Probe/Impedance Testing)
- Finally, each board undergoes full electrical testing using AOI (Automated Optical Inspection), flying probe tests, and impedance checks. Our team performs a final inspection to ensure every board meets strict quality standards.
This detailed process ensures every double-sided PCB from Best Technology is dependable, high-quality, and ready for advanced applications.
How Do You Make a Double Layer PCB?
Double Layer PCB is also named Double Sided PCB. The Double Layer PCB manufacturing process is the same as above double sided PCB manufacturing process listed. As a leading double layer PCB manufacturer, we are happy to provide quick double layer PCB manufacturing service to you.
How Are Double-Sided PCBs Soldered?
Double sided PCB soldering uses different techniques depending on component types. If both sides have surface-mount devices (SMD), one side is reflow soldered first. Then, the second side is processed with care to avoid disturbing the first.
Through-hole components usually go through wave soldering. For mixed assemblies, selective soldering is used to avoid reworking finished parts. Skilled operators or automated machines handle the job. Quality checks follow to catch defects.
Double sided PCB assembly is a key part of this process. Good manufacturers use AOI (automated optical inspection) and sometimes X-ray to ensure quality.
How Much Does a Double-Sided PCB Manufacturer Charge for Custom Boards?
Pricing depends on several factors:
- Board size and quantity
- Copper weight and layer thickness
- Hole count and via complexity
- Solder mask color, surface finish
- Lead time and testing
A custom board might start from a few dollars each for small runs, but the price drops with higher volumes. Always ask for a quote based on your actual Gerber files. A reliable double-sided PCB manufacturer will also offer suggestions to cut costs.
What is the Best PCB Manufacturer?
Finding the best double-sided PCB manufacturer is a key step when quality, turnaround time, and budget all matter. India has become a growing hub for PCB production due to its skilled labor and advanced factories. Here’s a brief overview of some trusted manufacturers based in India.

How to Choose a Reliable Double-Sided PCB Manufacturer?
Choosing a double-sided PCB manufacturer goes beyond browsing websites. Look for the following signs of a reliable partner:
- Clear communication and fast response
- Transparent pricing
- Quality management system in place
