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

Why does my RF PCB have small holes in the ground polygon?

I ordered RF PCB design and prototype from my supplier . There are something like a hole, but it is not, on the ground surface. What is the purpose of making these holes? The PCB is inside of the E70 433NW14S LoRa module.

Can leaded BGA chips be reflow soldered with lead-free process?

I know that using leaded process for lead-free BGA chips is not acceptable, because the solder balls of the BGA will not melt and the joint will be unreliable. But now BGA chip is only available in lead-free balls. is it ok to solder leaded BGA chips with a lead-free (thus, higher temperature) process?
