Who was it - cnc router for pcbs
Pretty sure someone here posted about making PCBs
using a cnc router, who was it?

It wasn't me (I don't think) but I used to do it that way and still have the router but the software won't work on any current
machines and its not worth the time or effort to fix when outsourced, PTH, multi-layer PCBs are now only 24 hours away on an express service from a
local supplier.
It had its use at the time (20 years ago) and I also then had a basic plating line so could do 'proper' 2 layer PTH boards but routing
fine pitch SMD footprints became and issue so we stopped using it.
Do you have a board you want doing?

Cant answer your question directly but I have had really good results over the years using photo-resistive PCBs... Print the mask using a
laserprinter and then expose the board in a home made UV box...
Could get all the bits from RS for under £50! I have even made double sided boards this way.... fiddly and requires manual drilling of holes but it
works.

I was looking for a quick way to prototype a board. I have all the parts, except box, for UV exposure method but was thinking a cnc router wold be
quicker that messaging around with chemicals to make the board.
I supposed I should get my finger out - I have the circuit and pcb layout so build it on a breadboard and once verified, make the pcb.
I got some uv mask film - what sort of time is needed to expose it - would it be a few seconds or minutes or hours? obviously depends on the power of
the uv source - (I have 10 uv led emitters) so not an easy question to answer.

We have all the stuff for making boards at work but haven’t done any for a while so not sure what’s in the etch tank etc
How complicated is your board-could you draw it using the old Dalo pen then etch/drill?

Yes, two boards pretty simple, probably less than 30 components (q, r, d and c)
