If you need highest quality and proper quality control after production, ALLPCB advance PCB is your best choice.This was the first time I was using the "Advanced PCB" option from ALLPCB not knowing what to expect. But the result was a tremendous improvement over all the other PCBs that I have ordered (that were also very high quality).
The PCBs took 1 day to ship out and finally arrived within 4 days. but did include hand signed, very detailed test reports (in English), a test sample (break test I guess) as well as humidity indicator.All PCB are exactly how I imagined them!!! Great work. Thank you!
