Manufacturing Process
1. PCB Fabrication Flow: Material Cutting → Drilling → Copper Plating → Circuit Patterning → Etching → Solder Mask → Silkscreen → HASL Surface Finish → Profiling → Electrical Test
2. PCBA Assembly Flow:
SMT Loading → Solder Paste Printing → SPI Inspection → Double-sided SMT Placement → Reflow Soldering → AOI Optical Inspection
DIP Component Insertion → Lead-free Wave Soldering → Cleaning → Manual Visual & AOI Inspection → FCT Power-on Functional Test → Final Cleaning → Packaging & Shipment
3. Process Features: Stable mounting of small-size components via SMT; wave soldering for through-hole terminals to guarantee high-current connection reliability. Full-process inspection prevents cold solder joints, short circuits and component misplacement, meeting long-term stable operation requirements of industrial equipment.
