Homebrew PCBs

You can also heat the board with a paint stripper heat gun.

BTW: In the Netherlands tinning powder can be bought at hobby markets under 
the brand Griffon. They sell it for about 6.95 euro for 250 gram. It is 
available as 40/60 tin lead or as 60% tin/silver (96.5 / 3.5 silver).

Kind regards,

Henk
