Solder Suppliers Ally for Lead-free Product
June 27, 2007 |Estimated reading time: Less than a minute
CLINTON, N.Y. and TWINSBURG, Ohio Indium Corporation partnered with Metallic Resources, Inc., to market, develop, and manufacture a line of lead-free solder with cobalt additives. Metallic Resources' proprietary tin/copper/cobalt alloy, Cobalt995, will expand into compatible and complementary cored wire and solder paste products through Indium's partnership.
Cobalt995, an alternative to SAC alloys for lead-free assembly, reportedly is more cost-effective than silver-bearing alloys, and provides bright, shiny, smooth solder joints in wave reflow processing. Metallic Resources has marketed the alloy for wave soldering, SMT assembly, and HASL finishes.
Indium will market the cored wire and paste, as well as bar form for wave applications. The partnership combines Indium's technological developments, technical support, and global services and manufacturing with Metallic Resources' electrolytic capabilities and alloy intellectual property (IP). Cobalt995's initial applications are in both wave soldering and rework processes, and future applications could extend into advanced packaging as well as SMT, according to company representatives.
