Manufacturing Process
- PCB Fabrication: Cutting → Drilling → Copper plating → Pattern transfer → Etching → Solder mask application → Silk screen printing → Surface finish (LF HASL, ENIG, OSP, etc.) → Outline → E-test → FQC
- Component Sourcing & Inspection: Procurement from authorized distributors → Incoming inspection (optical check, X-ray)
- PCBA Assembly: SMT/THT assembly → Reflow/ wave soldering → Hand touch-up (if needed)
- Quality Inspection: AOI → X-ray → Functional testing → Final visual inspection
- Packaging & Shipping: Anti-static packaging, custom packaging options, global shipping (DHL/FedEx/UPS)
