Dear Technet,
Help!!!!
Can any of you metallurgical/chemical wizard types
help me? I need to strip tin (?) plate off of brass. Hopefully without etching
the brass.
The plating solution was;
Flouboric Acid
Stannous Fluoroborate
Thiourea
This stuff soldered great last week but will not
wet this week.
I greatly appreciate any help,
Dan
