To anyone interested in etching their own PCB boards:
I have long sought for a really good etch resist pen. I use 2oz copper clad PCB board, and the usual etch resist pen doesn't work, hardly at all. The ink eats off by the time the copper is done etching. I have used a Liquid Paper pen, up until now. It worked the best. However, I recently purchased and tried a very interesting pen, called the 'Pump Pen', by Ackerman.
This pen, you can fill it with any kind of ink or paint you want. Hmmm. I just used the ordinary ink for nib pens, as my son has some. I tested it on some copper PCB, left it all night, and the copper was eaten off, and the ink is still fully in tact! I am leaving it on all day today, just to see how well it works. Needless to say, this pen works awesome for etching.
You can use ink, paint, whatever. I plan to do a test with fingernail polish. Fingernail polish? Yes, it is basically lacquer, I think. Anyway, it is an old old trick, using fingernal polish.
If you have been looking for a good way to etch your boards, and have been frustrated with trying to find a good etch resist ink pen, stop looking and buy this one.
(I am not getting paid for this plug, really! )
