Here is where a belt sander can come in really handy!! Even so, if you go this route,
GO SLOW!!!!!
You can go too fast and permanently damage your circuit board.
Ok, so you don't have a belt sander handy, did you notice your kit included some sand paper?
Yes, believe it or not you can actually do this by hand! Takes about 35 minutes of focused work,
but I have done this.
Think a few minutes of pain for many hours of pleasure.
You can use other methods, like a Dremel etc. And if you feel confident using those tools,
then please do what feels best for you.
Please be careful and take your time!
Keep the circuit board firmly secure and use even pressure and even strokes!
