BANNOCKBURN, Ill. — IPC's Pb-Free Electronics Risk Management (PERM) Council has released a white paper, “PERM Council Pb-free Research Priorities” that identifies priority research areas regarding the impact and risks associated with the implementation of lead-free materials in electronics. The research areas include tin whisker failure modes and risk mitigation, complex systems logistics and lead-free interconnections. Each of these areas were explored across five industry platforms: avionics, ground-based systems, missiles and aviation systems, space systems and submarine and sea systems.
The research within the 25-page white paper is part of an ongoing effort that began with the 2010 Lead-Free Manhattan Project (LFMP), undertaken to address the challenges that arose with the use of lead-free materials/products, shortly after the use of tin-lead, a mainstay of the electronics industry for many years, was restricted.
“It's been nearly a decade since the European Union passed the Restriction of Hazardous Substances (RoHS) Directive, but the electronics industry is still grappling with the transition to lead free,” said Linda Woody, Lockheed Martin Missiles and Fire Control and PERM Council chair. “Some high-reliability markets such as aerospace and military still have a number of issues that haven't been resolved and there are still many gaps about long-term performance in demanding applications. Giving attention to the topics discussed in the white paper is a solid first step toward development of an industry-wide, comprehensive risk mitigation strategy.”
