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.

How can I fix the PCB to the mechanical structure?

I designed a PCB with an imaging sensor that is mechanically coupled to a lens assembly using four 2-56 schroeven. I’m noticing that even though the screws are holding the board tightly against the mechanical structure if I flick or lightly knock the the assembly the image “moves”. I’m hoping to get a few suggestions for ways to fix the PCB to the mechanical structure. Any suggestions for adhesives or the like? Something else?

Is it possible to replace an automotive wiring harness with PCB?

Is it possible to replace an automotive wiring harness with PCB? Bijvoorbeeld, just have the cables attached on either end of the circuit to eliminate a bunch of messy cableage in between.

Wat is het verschil tussen een prototype-PCB en een productie-PCB??

My project have gone through from design, prototype to mass production after lots of discussion and adjustment. Now the manufacturer are making our products in their product lines. And I would like to know is there any differences between the prototypes in my hand now and the final products output by the manufacturer?
