Ring PCB：One-Stop Industrial Mainboard PCBA Service, High-Density Multilayer Fabrication & SMT for Small-Medium Batch Industrial Electronics
1.Product Features
- Adopts high-Tg FR4 multilayer substrate, withstands -40℃~85℃ wide temperature range; thick copper power traces improve load capacity for harsh industrial conditions.
- High-density PCB layout with large-size BGA chips, blind & buried vias plus impedance control to guarantee stable high-speed signal transmission.
- Hybrid SMT & DIP assembly: industrial-grade components, mixed mounting of big BGA, mini 0201 parts and long-pin connectors with excellent anti-EMI capability.
- Widely used for industrial automation controllers, embedded IPC and machine vision mainboards; customizable full turnkey service for small & medium batches.
2.Core Manufacturing Process
- PCB production: Multilayer pressing, laser blind hole processing, impedance tuning and ENIG surface treatment for long-term soldering reliability.
- PCBA assembly: High-precision SMT for large BGA, 100% X-ray inspection to eliminate invisible solder defects; wave soldering for through-hole connectors.
- Strict reliability tests including ICT, FCT and burn-in aging; optional conformal coating for moisture, mold and salt spray resistance.
