Title: Cut an FR4 plate?
Post by: Morbii on Mon, 19 December 2022, 05:21:33

I have a solderable PCB that supports stepped caps, but the FR4 plate does not.  Is there a tool that can easily extend the hole for the caps lock to make it work?

Same question for: POM, Aluminum, Brass

FR4 is fibreglass, and it is hazardous to inhale the dust. Be sure to wear goggles, gloves, a protective mask (not a medical one) and work in a special area that you don't live in. Collect all dust by doing it on top of paper or plastic that you fold together and get rid of. Then change clothes.
I also use a vacuum cleaner nozzle propped up to point directly at the item I'm working on. That way, the vacuum should suck up most of the dust.

As to tools: Dremel with cutting wheel or routing bits.
