Score the board deeply on both sides with a sharp scriber, snap the
board along the scribe line and neaten up with a file. Clamp a steel
rule to the board as a guide when scoring and practice on a piece of
scrap board first.

The method is quick neat and accurate and requires no special skills,


Thanks Keith. Several people have suggested this method so I am going to
experiment on a piece of scrap and see how it goes.

And when you snap it, lay the board on a table edge, aligned with the
scoring. Apply more pressure to one end than the other and it will
kind of tear along the line rather than snap. It will all be under
much more control that way.

Thanks for the tip Don.

Hi
The term to use in a search is PCB milling.
It's the internet and the very subject has been covered 49 million times.
This is not the group to get solutions on almost anything!
A search will bring you all the results you need. For amateur/occasional
use the most popular tool is a Dremel which can be picked up on
ebay for a tenner, or hired for day as a full table top mill for 6 quid.
If bought on ebay you can then resell it after use or use it to cut
kitchen tiles, or heart shaped holes in neighbours windows etc.
I did a brief google on Dremel PCB milling and from first page of results
am supplying these video links:

On YouTube there are thousands more clips on the subject of PCB milling.

A Dremel is extremely versatile, apart from this subject they are
pretty nifty with mobile phones, but thats another subject not ffor usenet.

PS. PCB's can be layered, so scoring and snapping can result in cracking
with some structures, milling is the safe option.
