Re: PCB etching service

Hi Tony

It's a good method and I made some good boards using Epson photo paper,
then I bought some more Epson photo paper and had a lot of trouble
peeling it and the edges of the tracks were lifting. So then I tried
some HP inkjet paper (cheap on special offer) and found that impossible
to peel - couldn't even get to the etching stage.

I paid £10 for the toner transfer paper and it does work very well but I
agree it's pricey.

I've wondered whether it would be possible to brew your own. The toner
transfer paper is an OHP film with a coating - I've wondered about spray
paint - I might experiment - I do have access to a laser printer that I
can afford to ruin.

Wanted to suggest them too. I let make my boards there.
Without solder stop mask etc, they are not so expensive. They accept Eagle
or other files directly without extra charge.
Good and easy online ordering, fast turnaround (at extra charge).

Seems so - it was the dollar pricing that I based it on. Whatever happened
to the Euro?

Umm, maybe they are using England as a good example and ignore the EURO? ;-)

I saw an ad. for one on eBay the other day. IIRC their offer was
for 79p per square inch plus a tenner set up costs for double sided
irrespective of the number of tracks/holes etc.
I didn't make a note of it as I wasn't looking for PCBs then.
You can probably find it if it's still there - I don't know if that's
a good price as the few PCBs I've needed I've made myself

Pete

p.s. no, it's not my eBay ad.

Are you thinking of polychlorinated biphenyls? These are indeed highly
hazardous, and very restricted - they were used in large transformers,
may still be for all I know. However, Russell was using PCB as an
acronym for printed circuit board.

Of course, you may have known this, but there was no humour clue in your
post.

that's horrible

I've been against this since day one.
no one could tell me this would have been worth it then nor now.

thanks for the clarification. That points me in a better direction,
for understanding, the process that was described. interesting.

Printed circuit board laminate is of course not illegal, though some
flame retardant additives they used to put in the glass fibre are now
banned. Try farnell or RS.

Polychlorinated biphenyls as used in transformer oil have been banned
for a long time and there is a big industry in replacing them either
with whole new transformers or in some cases by decontaminating
existing ones.
