Lead-Free Compound
Lead-free soldering barcomprised of various combinations of tin, copper, silver and antimony. Pure tin wire has the highest melting point of 449 degrees. Other combinations of metals melt in a range between 419 and 441 degrees.It is used for wave soldering technique and handling solder.
SAC plus0307 solder stick/bar description:
SACX plus0307 is a patented (US Patent No 4,929,423) lead-free alloy suitable for use as a replacement for Sn63 alloy in the wave solder process. The SACX plus0307 variant is used to stabilize / reduce the copper content in the wave solder bath, this requirement will depend on process conditions. As with all our Metals bar solder, our technician alloying process is used to remove certain impurities, particularly oxides. The product is further enhanced with the addition of 2 minor elements to reduce dross formation and improve the joint cosmetics.
SACX Plus® 0307 also delivers the same high yield wave soldering and reliability performance as the original. As with all SACX alloys, minimal solder dross is also produced due to our proprietary Vaculoy® manufacturing process and the addition of just the right amount of proprietary additives.
