I guess this topic has probably been thrashed out many times here
but........
I'd really like to move away from Veroboard and make my own PCBs.
I have fallen in love with Marix Multimedia's Technodrill, a sort of mini
three axis CNC machine which mills the copper from the board but the price
is way out of my league.(
http://www.matrixmultimedia.com/articles/Engineering.pdf page 9)
Bearing in mind I'll probably only be making the occasional small board I
seem to have two choices. Press and Peel and photo resist boards.
Having read the instructions on the back of a pack of Press and Peel in
Maplins (I'm in the UK) it warns of the tracks 'spreading' if you press too
hard with the iron so it doesn't sound like a foolproof method. It also
mentions 'topping up' the tracks with a etch resist pen if they don't adhere
to the board. I also wonder if you can send a sheet of Press and Peel
through a laser printer a second time if you've only used a small portion of
the sheet.
Photo resist sounds good as (I assume) you can print onto easily available
overhead projection film but (again I'm assuming) will need another chemical
to etch the photoresist from the board before you etch the copper. More
trips to Maplin only to find they are out of stock, unless you can get the
right stuff from the chemist.
Any tips from the PCB makers on here?
Regards
