We use our drill press to make holes in our own circuit boards, and tap or break traces on existing circuit boards. We’ve used a lot of tools to drill circuit boards — power drills ...

Now it’s not going to line up the bit with the exact location of the hole (that would make it a fully automatic drill press). This works by lining up the board manually, then stepping on a pedal ...

As demand for next-generation semiconductor chips grows, a team of researchers has succeeded in laser-drilling the world's tiniest circuit board holes, measuring a near-inconceivable 3 micrometers ...
