An economical two-step solder stripper that rapidly strips tin/lead or tin deposits from
printed circuit boards. MAGNUM NPS-220 removes all but a thin protective layer of
metallic tin to inhibit excessive attack on the underlying copper. The protective layer of tin
is then removed with MAGNUM NPS-240.
MAGNUM NPS-240 quickly removes the intermetallic layer, leaving a clean, tarnish-free
copper surface. It can be used following standard tin strippers, and also to clean copper
prior to hot air leveling. It contains no fluorides, peroxide or ammonium compounds.
