Homebrew PCBs

Chuck
If you are only doing a few PCBs then HSS drills are cheap enough to throw away after each board drilled.
I use a Missed Hole drill I made from a 12V DC motor and a pin chuck for the odd hole, or you could build one of your own. Photos in my album MParker-Lisberg:

You need a low run out and no spindle feed backlash to use carbide drills..

I don't suffer from insanity I enjoy it!

      I just made my very first PCB at home!!!  Hooray!



http://www.instructables.com/id/Easy-to-build-CNC-Mill-Stepper-Motor-and-Driver-ci/

I made the "Easy Stepper" board from Instructables, and could not easily get etchant out where I live, so I used the toilet bowl cleaner/peroxide mix.  Worked quite well, actually.



And, I did it as LASER toner transfer, using magazine paper.  Talk about low tech!



Apparently it really *is* possible to make boards, at home, and affordably.  Next step is going to be drilling them out.



I have 1/16" drill bits that would fit my drill press, or my Dremel...and I have a 0.7mm solid carbide bit that fits either as well.  My concern is runout and precision...carbide is very VERY brittle, and I have only one bit.



Any hints for a first timer?



THANKS!



Chuck
