down. Again most suppliers need a drill file from a cad package before they
will drill for you.
What were RAK like in quality terms (and to deal with), as a matter of interest ?

Possibly true, but only if your time is free. Personally I'd rather pay for the
quality of a manufactured pth tinned silk-screened board rather than the
dubious quality I'd be able to produce at home, especially if doing the lining
by hand rather than by CAD.

There is a big learning step and overhead with converting designers used to
old methods to a PCB CAD package.
I learned on black tape and mylar sheet and have migrated to 'electronic'
black tape using macdraw or Visio nowadays and it is still quicker for me to
work this way for small jobs.

Even professionally, it will cost me many man hours to convert my older
staff to CAD. It is cheaper to let them use the methods they are used to.
Bright young graduates in contrast have often used a cad package at Uni and
use it with ease.

Until a couple of months ago I had a PCB services lab on site at work and
could get ds pth boards made in about 3 hours. but now thanks to huge
expenditure needs to satisfy waste control requirements, we had to close it
down and make the staff redundant.

This is why I went to RAK and they were very good to deal with.


The OP was talking of etching charges of around £5 - which led me to my
comments on 'kitchen sink' methods.

Bob

Dunno why you'd do it by hand given you have a computer. I don't even use
a cad prog for most things - just good ol' Acorn Draw, although I do use a
later version (Millennium) with a library for my symbols.

And the results you can get are perfectly fine for anything you can
assemble by hand.

There is a nice program called PLATINCNC that will take artwork as an
image (.jpg bitmap etc) and convert it into G code to CNC mill the PCB
and identify all the holes and drill them. It actually works quite
well despite the rather odd English used in the instructions (the
author is an Austrian post grad student) I last used it to re-make
gaskets for a slide valve !

You could try KCS Electronics in Crewe:

http://www.kcscrewe.demon.co.uk/

I don't know whether it's a service they normally offer, but it's a business
they are in and might be able to either do it, or point you in the right
direction.

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.

Acorn Draw was/is a damned fine program for diagrams. I've never found
anything as easy and effective for the PC.

You can of course run most of these RISC OS programs on a PC using an
emulator.
