PCB Manufacturing Process
Our PCB manufacturing process goes through multiple precision manufacturing stages to transform design files into finished circuit boards
1. Engineering Review
Before manufacturing begins, our PCB engineers analyze the customer’s design files to ensure the PCB can be produced reliably.
We will review:
- Gerber Files
- Excellon Drill Files
- PCB Layer Stack-Up Information
- Fabrication Drawings
- Netlist Files
- Bill Of Materials (For PCBA Projects)
2. Material Preparation
After design approval, PCB production begins with material preparation. After confirming the PCB material, we will process these materials.
Typical PCBs are composed of :
- Copper Foil: Provides electrical conductivity.
- Dielectric Layer: Provides insulation between copper layers.
- Core Material: Provides mechanical strength.
- Prepreg: A bonding material used during lamination.
3. Inner Layer Imaging Copper Surface
Copper surfaces are cleaned to remove:
- Oxidation
- Dust
- Contamination
A clean surface ensures proper photoresist adhesion.
4. Inner Layer Imaging Circuit Pattern Exposure
The PCB artwork is transferred onto the photoresist using:
- Laser Direct Imaging (LDI)
- Photolithography systems
The exposed areas define the circuit pattern.
5. Inner Layer Etching
After imaging, unwanted copper is removed through chemical etching. The process creates the actual circuit pattern.
Etching Process
- Protected copper remains
- Exposed copper is removed
The result is a precise inner-layer circuit.
6. Inner Layer AOI Inspection
After etching, inner layers undergo Automated Optical Inspection. AOI systems compare the manufactured PCB layer with the original design database.
AOI Detects:
- Missing Traces
- Extra Copper
- Short Circuits
- Broken Circuits
- Pattern Defects
- Alignment Errors
AOI inspection is critical because inner-layer defects become impossible to repair after lamination.
7. Layer Lamination
Multilayer PCB manufacturing requires bonding multiple layers into one solid structure.
- Lamination Process Steps 1. Layer Alignment
All PCB layers are precisely aligned using optical targets. High accuracy is required because even small alignment errors can affect via connections and signal performance.
- Lamination Process Steps 2. Heat and Pressure Application
The stacked PCB layers are placed into a lamination press to create a permanent bond.
8. CNC Drilling Process
After lamination, holes are drilled into the PCB.
PCB drilling creates:
- Through holes
- Via holes
- Component mounting holes
9. Copper Plating Process
After drilling, hole walls are not conductive. Copper plating creates electrical connections between PCB layers.
- Plating Steps 1. Chemical Copper Deposition
A thin copper layer is deposited onto hole walls and PCB surfaces.
- Plating Steps 2.Electrolytic Copper Plating
Additional copper thickness is added to improve current carrying capability and mechanical reliability.
10. Outer Layer Imaging and Etching
The outer layer imaging and etching is one of the most critical stages in PCB manufacturing. It creates the external copper circuit patterns that connect electronic components, connectors, and other electrical elements on the finished printed circuit board.
It Includes:
- Photoresist Coating
- Circuit Imaging
- Copper Plating
- Etching
- Inspection
11. Solder Mask
The solder mask is a protective coating applied over the PCB surface. It is commonly recognized as the green layer covering most PCBs.
Solder mask provides:
- Prevents copper oxidation and environmental damage.
- Prevents accidental short circuits.
- Prevents solder bridges during assembly.
Common Solder Mask Colors
- Green
- Black
- Blue
- Red
- White
- Yellow
The color choice usually depends on customer preference.
12. Surface Finish
The exposed copper pads require protection before component assembly. Surface finish improves solderability, corrosion resistance, and storage life.
Common PCB Surface Finishes
13. PCB Cutting and Profiling
After surface finishing, individual PCBs are separated from production panels.
Methods Include:
- CNC routing
- V-scoring
- Laser cutting
14. Electrical Testing
Before shipment, finished PCBs undergo flying probe testing.
15. Final PCB Inspection
The final quality inspection ensures that every PCB meets customer specifications.
Our inspection teams verify:
- PCB Appearance
