Our PCB are widely used in smart electronics, communications Technology, power technology, industrial control,
security engineering, automotive industry, medical control and optoelectronic engineering and other fields.
Our circuits boards range from double layers to 24 layers.
The product types include ordinary boards, medium and high Tg boards, involving special processes such as semi-hole,
bonding, impedance, blue glue, carbon oil, gold fingers, blind gongs, buried blind holes , Countersunk holes, etc.;
surface treatment can be ordinary tin spray, lead-free tin spray, immersion gold, electro-nickel gold, electro-hard gold,
QSP, immersion silver, immersion tin or composite processes, etc..
Our PCB factory is fully qualified and has passed a series of certifications including UL, ISO9001, ISO14001,
ISO/TS16949, CQC and so on.
