When I learned electronics in the 60's, acid flux was a no-no for electronics. It would cause corrosion in the weeks following the solder operation. Acid was for plumbing only.
Silver solder--what wattage soldering iron?
I need to solder some new Cardas cartridge clips onto my Rega RB600, and I'm having trouble using a Radio Shack 40W soldering iron with the silver solder that came with the clips. Doesn't seem like I'm getting enough heat, even after I cleaned the tip with sandpaper. Does this iron have enough wattage, and if not how much do I need? Thanks, Will Herrera
