Haha! TomDude that's beastly - using inorganic acid flux from the plumbing aisle for electronics! I hope you're not in the satellite business! I'm no electronics repair expert so maybe Marlin can confirm or dispel this - but I've heard it's better to stick with rosin or some other organic-based flux (i.e., less acidic) when soldering electrical stuff. Corrosion and circuit boards generally don't mix well...
