The bare circuit board may be assembled on different levels. A cheaper level of the board may have some missing parts that go into a final product at a cheap level. Some boards with special features tend to face the same problems, too. Label part numbers to help identify this problem.
By the way, the assembled board might have a stick-on label with the final assembly number.
#PCB Assembly
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.
I recently finished my PCB design files and had to release to manufacturer for order production, but I am really worry about file confidentiality leaking. How can I in this case?
Last week, I visit a PCBA manufacturer for our new project. They not only introduce in-circuit tester but also flying probe tester, which can both ensure the quality level. So, Why does the manufacturer use a flying probe tester when they already have an in-circuit tester?
