This works by lining up the board manually, then stepping on a pedal to activate the plunging motion of the drill. A linear motor is responsible for the smooth, accurate motion along the Z-axis.

It’s the prefect size for working with circuit boards, and worlds better than any high-speed rotary tool we’ve had the displeasure of using. The drilling action is very smooth, and the motor ...

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 ...
