I’ve ordered fabrication and assembly of small PCB batches (100pcs) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Then, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.
We are glad to find you have ISO and BSCI certification. Could you please tell what is the warranty of your PCBA product? I mean, on average.
A batch of PCB got wet in warehouse due to roof linking. Too terrible to shoulder the lost. How can I do to rescue these wet PCBs? Or to minimize the damage?
