Homebrew PCBs

If this helps
I just ordered a pure tin bar from mcmaster carr industrial supply.

Also I saw no comments on my previous post on this issue with the digikey
link
Now is this totally different then what the link specified???
because that part# was for a silvering kit/powder according to the
instructions you just dampen the corner of a cloth with water then touch the
powder ,then rub the pcb traces with the cloth , and you now have a silver
plating or??? on the board
as far as I know it does the same thing as tinning but no harsh chemicals .
I have not tried it I have spoken to the supplier  (Dynnarart) and he has
explained it to me.
so next time I need to order from digikey or dynaart I will get some.
the cost is $30.00 but from what I can see it will last a long time.
regards
victor
