We test and control the quality of products according to American IPC and MIL . We have got UL ,CQC TS16949 and ISO14000 certificates ,so we can sell safe printed circuit boards&pcba to all countries over the world. About the Smoke detector,because of the good quality and working life,they are very welcomed by many customers.
Our strict quality control system for PCBA:
1. E-test for PCB.
2. IQC for components.
3. AOI test
4. PCBA function test
We have got UL, ROHS, ISO9001 certifications. We can provide PCBA for prototypes, small volume and mass production.
