The data sheet for the LT3080 linear voltage regulator suggests using printed-circuit-board (PCB) traces for ballast resistors. Although the LT3080’s low offset voltage suits it well for this ...

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 ...

This rule of thumb is the most important DC resistance figure of merit about copper foil used in a printed circuit board. Spoiler summary: The sheet resistance of 1oz copper foil is about 0.5mΩ per ...

Determining the exact physical location of a short circuit in a printed circuit board can be fiendishly difficult. The millivolt measurement method described can help A few weeks ago I was asked to ...
