Double-Sided PCB Manufacturing & Quality Control Process:
- Receive customer’s Gerber files and design requirements, then conduct design review and optimization.
- Select high-quality FR-4 base material and prepare for 2-layer PCB fabrication.
- Perform core processing: cutting, imaging, etching, drilling, copper plating and via metallization.
- Apply green solder mask and lead-free HASL surface finishing as standard.
- Conduct electrical testing, AOI, and dimensional inspection to ensure performance stability.
- Provide rapid prototyping validation before formal mass production.
- Implement strict quality control throughout production to guarantee consistency and reliability.
- Package and deliver finished PCBs for industrial control, consumer electronics and IoT applications.
