I'm wondering where I can buy the 'Tin-solution' that is used to Tin-plate PCBs.

Try 'http://www.allectronics.com'. I think you're looking for item 'ER-18'.

Good luck.

Hi Freddie.

Why do you want to tin-plate your PCB's?

The intermetallic layer created between the Cu and the tin-plating causes an increase in the resistance, and it'll give no better protection than a good PCB-lacquer.

Freddie,

Don't use chemical tin-plating, this may cause failures because of the poor quality of the chemical tin layer.

Regards, P.Lacombe.

Thanks for the replys.

So it is bad to use chemical tin-plating.
Then I will use PCB-lacque instead.

There's no need to buy special lacquer. Save your money for other things.
I use Sherwin Williams clear acrylic lacquer. Easily avaible, not particularly expensive, and works like a charm. I have circuit boards over ten years old that look as though they were made yesterday. I spray the board before populating it--the lacquer melts away at the slightest amount of heat, so there's no problem soldering through it.
