- [Company News]Surface assembly process design principles2019/11/16/ 11:27
- Typical surface assembly methods include full surface assembly, single-sided mixing, and double-sided mixing. Full surface assembly means that both sides of the PCB are mounted components (SMC/SMD); single-sided mixing means that both the SMC/SMD and the through-hole components(THC) are on the PCB, and the THC is in the main Face, SMC/SMD may be on the main side or on the auxiliary side; double-sided mixing means that both sides have SMC/SMD, THC is on the main side, and there may be THC on both sides.

- [Company News]Electronic circuit board manufacturng 5s management2019/11/02/ 11:44
- 5s management is the basis of on-site management. The 5s management originated in Japan and refers to the effective management of production factors such as personnel, machines, materials and methods at the production site. This is a unique management method for Japanese companies. Since Seiri, Seiton, Seiso, Seiketsu, and Shitsuke are the first letters of the Japanese alphabet, the first letter of the Roman alphabet is "S", so it is simply referred to as 5s.
