PCB/PCBAssembly/PCBA OEM suppliers

1. We have the most advanced SMT machine Mydata which is fully automatic. It can distinguish component's direction automatically during soldering, finding correct components value if the operator put the component at a wrong place.

2. Our solder paste printer is also automatically which is more precise and symmetrical, all of them are imported from Japan. (KOKI)

3. We have wave soldering machine to do through-hole soldering, supporting large-scale need.

4. We do 100% AOI testing after surface mount, which can check out components'missing, wrong direction, solder insufficient, ect.

5. Our management system is TS16949: 2002, since we provide OEM service for auto parts in car stalk ,like Honda, BMW ect.
