Do the scratches on the PCB have any bad effect to products?

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 ISO9001 management system as a backup supplier against the one you are cooperating with now.
