Copper corrodes quickly when exposed to oxygen. You must protect copper traces on outer layers from corrosion by passivation or by coating them with an inert material. Passivation refers to any ...

Solder is the conductive metal glue that one uses to stick components together. If you get the component and the PCB hot enough, and melt a little solder in the joint, it will stay put and conduct ...

Soldering to a PC board can be tricky: Too much heat can make the copper trace lift right off the board substrate. Use a soldering pencil rated at 15-25 watts, no more. (Watch the video; story ...

PORTLAND, Ore. — Soldering chips to boards may become a thing of the past as a result of research on copper materials sponsored by Semiconductor Research Corp. (SRC, Research Triangle Park, N.C.) at ...

Printed-circuit-board (PCB) substrate material, like FR-4 glass epoxy, is a poor conductor of heat. Conversely, copper is an excellent conductor of heat. So, more copper area on a PCB is ideal from a ...
