IPC Solder Products Value Council Takes Action on Take Action Limits
BANNOCKBURN, Ill., August 23, 2007 — It didn’t take long for new IPC Solder Products Value Council (SPVC) chairman, Karl F. Seelig, vice president of technology, AIM, Inc., and IPC SPVC Technical Committee chairman, Paul Lotosky, director customer technical support, Cookson Electronics, to get the group of leading soldering manufacturers moving on its next project. Its first action — begin a research program on Take Action Limits (TAL).
“Take Action Limits, also known as ‘dump pot specifications,’ are very important to any electronics manufacturing company using flow soldering techniques either in selective soldering or wave soldering,” explained Seelig. “Our objective is to develop better-defined limits to guide electronics manufacturers on a more efficient use of solder and as a result, improved yields.”
In an effort to provide consistent recommendations for action levels on contaminate of wave soldering alloys, the SPVC is evaluating the effect of impurity limits on performance of lead free solder by conducting wetting time and wetting force tests. In addition, samples will be sent to a third-party test facility to determine if a correlation exists between bridging and copper concentration.
The Council plans to publish its findings and list TAL, along with guidelines for solder pot management, in the first quarter of 2008.
Lotosky, who is heading up the research effort, explained “this is an excellent example of how the global solder suppliers are working together to help improve the soldering process for the electronics assembly industry.”
