For the next time you use your Dremel tool.

1. Don't tell your wife/husband what you are about to do.
2. Send the children to the movie theatre.
3. Give a bone to the dog.
4. Open the window. (Not MS-Windows).
5. Wear protective glasses, dust mask and protective gloves.
6. Put the vacuum cleaner hose next to the cutting point.
7. Turn the vacuum and the Dremel on.
(The vacuum noise will cover the Dremel noise. She/he will
think you are finally cleaning "that" mess and she/he will
not disturb you in any case).
8. Do the job.
9. Turn the Dremel and the vacuum off. (See step 7 about noise).
10. Remove the protective glasses, dust mask and protective gloves.
11. Ask your wife/husband where are the replacement vacuum cleaner bags.
(She/he will think the cleaning job is not completed).
12. Forget about the vacuum cleaner, go back to your serious work.


Important items:

- Protective glasses.
- Protective dust mask.
- Protective gloves.

1. Use a ruler and score a deep grove - both sides.
2. Place pcb in vice and line up on the score mark.
3. Snap it!

4. Sand back edge.

For small PCBs < 4 " I simply use a strong pair of "metal sheets scissors" ...

neat cut.

metal shear cutters are horibble, they do not cut anything, rather they crack the pcb in a direction that only slightly resembles a straight line. only usefull if you are using it to trim off excess pcb.

So, we don't use the same tools ...

I ended up using the score and snap method for some and the tin snips for the others. Worked fine. The paper cutter would have been easier yet.

Best way, use a jump shear, second to that any manner of sheet metal shear, notching punch. Sawing and grinding is too hazardous to YOU and family. Second to that score and break and wet sand the rough edge. If you insist on grinding, routing this stuff, go on a still hunt for a brake vacuum made to collect asbestos. FR4 is just as bad.
