Hebben de krassen op de printplaat een slecht effect op producten??

We receive a batch of PCB with scratches from my supplier, but they think it is acceptable. I have never seen such error on even an B stock boards parts. Very confused. How do scratches affect PCB working?

It depends on where the scratch is.

If the scratches are on the trace, it affects PCB working. Check whether your circuits are broken.
If the scratches are on the coppering area, it also affects PCB working.
If it happens in other places, there is few bad effects to PCB working.

Contact your supplier and give a quality assurance warning. Unstable product quality is a serious factor for your business, though you just sell in the retail market. It is advisable to find a supplier with ISO 9001 management system as a backup supplier against the one you are cooperating with now.

Can we do wave solder the through hole parts without masking it?

We would like to do wave soldering for the through hole components. All through hole components are top side of PCB. Only test points, which require mask during process, are on the bottom side. So there is a extra labour cost at adding and removing the mask. Can we do wave solder the through hole parts without masking it?

What are the possible reasons that a PCB doesn’t work?

I design a PCB file for samples and send it to manufacturer, but the samples can’t work now. We are trouble shooting the reason now. What are the common reasons you have met in a wrong PCB?
