A New (Better) Approach to Tin Whisker Mitigation

Mar 03, 2011 | Craig Hillman, Gregg Kittlesen, and Randy Schueller

Most of the electronics industry by now knows about tin whiskers. They know whiskers are slim metallic filaments that emanate from the surface of tin platings. They know these filaments are conductive and can cause shorts across adjacent conductors. And they know that these shorts can cause some really bad failures (see nepp.nasa.gov/whisker/ for a list longer than you need). But, with all of this knowledge, the industry is still struggling on how to predict and prevent these "Nefarious Needles of Pain"....

Digital manufacturing for traceability: The way to higher product quality and better warranty management

Aug 26, 2010 | Siemens PLM Software

Driven by high-profile regulations compliance like the TREAD Act, warranty management has become a hot topic across industries worldwide. Recalls are costly and time-consuming events that should be avoided entirely. But without adequate process traceability and product genealogy, too many customers will get defective products and too many products will be recalled for repair or replacement even though they are not defective. Both scenarios have enormous implications for the quality-conscious manufacturer that gets rated on the number of recalls it performs - not to mention the enormous direct costs. The core issue is visibility into product quality....

As technology becomes increasingly reliant on electronics, understanding the reliability of lead-free solder also becomes increasingly important. This research project focused on phase transformation kinetics with the lead-free solder SAC 305. Today in the electronics industry, SAC 305 is the most widely used solder, making it a high priority to understand its long-term stability and performance in a variety of service conditions. Recent evidence has shifted the focus from thermal aging to reflow temperature and time above liquidus values during initial solder melting....
