PCB Manufacturing Process
Key Steps in PCB Manufacturing
- Design Phase: Engineers use CAD software to create circuit schematics and PCB layouts.
- Graphic Conversion Phase: Circuit designs are converted into Gerber files essential for subsequent processes.
- Plate Making Stage: Photoresist films are produced using Gerber files to define circuitry on copper foil.
- Etching Stage: Excess copper is removed from the plate to reveal desired circuit patterns.
- Drilling Stage: Precision holes are created for component installation and interconnections.
- Coating Stage: Solder mask is applied to prepare the board for soldering operations.
- Welding Stage: Components are mounted and soldered onto the PCB board.
- Testing Phase: Quality verification through techniques like AOI and X-ray inspection.
- Cleaning Stage: Thorough washing to remove contaminants before final assembly.
