Cutting a trace

(1/3) > >>

What's the best way to cut a trace (ie disconnect it) on an existing PCB?  The service notes on a power supply i own required that I do it.  Needless to say the circuit board, while still working, looks awful having taken a screwdriver to it since nothing else seemed to work.

A utility knife, a scalpel even hand twisting a small diameter drill bit seem to work effectively.

Looks like it is high time I drive down to Office Depot to pick up that X-acto knife I've been meaning to get.  Wish I could undo the damage I did to that poor PCB.  C'est la vie.

I find a Dremel tool with a 1mm or 1.5 mm ball tools does the job for me.

Just don't consume any coffee before hand, Wait until the the job is one then pour a pot.


If i do not have to connect this trace later i just drill it in the middle with a drill bit little more wider than trace. If i really need it to look professional i "delete" it with CNC for PCB manufacturing  :)
