How to prevent mistakes that delay your PCB assembly (and could cost you)
Many designers can’t get their board fast enough after sending their PCB design files to their PCB assembly vendors. But the surprising thing is some customers do not provide sufficient and necessary information to their contract manufacturers (CM) – causing problems, delays,...
