Questions and Answers


Q: What files do you use in PCBA fabrication?


A: Gerber or Eagle, BOM listing, PNP(we can make if you have no it) and Assembly drawing(we can make if you have no it).



Q:Is it possible you could offer sample?


A: Yes, we can custom you sample to test before mass production



Q: When will I get the quotation after sent Gerber, BOM and test procedure?


A:  Within 6 working hours for PCB quotation and around 1-2 working for PCBA quotation. 



Q: How can I know the process of my PCBA production?


A: 7-15 days for PCB production and components purchasing, and 5-7 days for PCB assembly and Testing



Q: How can I make sure the quality of my PCBAs?


A: We ensure that each piece of PCBA products work well before shipping. We'll test all of them according to your test procedure. Also if there are any defect items during the shipping, we also can be free to repair  for you.
