PCB Chemical Etching Process
In the PCB production process, copper clad laminates undergo several steps:
- Surface cleaning - Remove oxidation and contaminants for better adhesion
- Photoresist coating - Apply light-sensitive film to protect circuit areas
- UV exposure - Transfer circuit pattern using artwork film or LDI
- Developing - Remove unexposed photoresist to reveal copper for etching
- Chemical etching - Dissolve unwanted copper using alkaline or acidic solutions
- Resist stripping - Remove remaining photoresist to expose final circuits
- Final inspection - Verify circuit integrity and dimensions
