How do you handle a PCB that didn’t print correctly?

I did have one board come back with a manufacturer error - an extra bit of copper just a hair’s width across hidden underneath a component. It looked almost like someone’s eyelash had fallen onto the board just before photo etch. How should I deal with it?

Try to use your backup PCB supplier with a good quality assurance system. Meanwhile, give feedback to these suppliers and ask for quality development.

This usually can be caught by the board manufacturer, but cheap board houses offer testing as an optional add-on.

If the errors are with the design, but not with the manufacture.

A good factory may recognize them help you fix the error by cutting and jumping, especially if the design is low speed and low current. What’s more, Good technicians are nearly magical with their ability to get tiny wires into tiny spaces!

What Others Are Asking

Are there any standard materials used to cover PCB SMT pads?

I have a PCB that was poorly designed and there is a ground pad that is too close to a signal pad. As a result, the signal pad on the surface mount component will short to ground. I was looking to use some ink or other material to cover the ground pad. The pads are too small to fit Kapton tape. Are there any standard materials used to cover PCB SMT pads?
