Video on board etching
Brass_Machine:
I remember there being a discussion about PCB etching... here is a video I just got the link for...
John Rudd:
Thanks for posting..
Not bad...
A couple of tips for those thinking of doing their own....
I use Ferric Chloride for etching my own boards, but I heat it first in a microwave oven, this and agitating the board results in a board being etched in a lot less time than the demonstrator states...
After the board has been etched and cleaned I use Tin Plating crystals to add a tin plate coating onto the track...aids soldering and protects the copper from tarnishing...
I find the hardest part is drilling the holes...My eyesight isnt as good as it was 20-30 yrs ago :(

I do the same microwave/agitating bit. Goes much faster.
Tell me more about the tin plating??

John Rudd:
Eric,
Basically you take tin plating crystals dissolved in hot water ( 50deg C) place the board in the solution and the copper is coated with a layer of tin...Takes up to about three hours depending on the thickness of the plating you want...
Not sure if its available across the pond but I would have thought so from RS or Farnell..
Bernd:
Eric,
I did a google. Lots of places here in the US.
Wish I could remember what I used back when I did circuit boards. Maybe it'll come to me.
Bernd
