Pb-Free Electronics Risk Management (PERM) Council 

perm logo 600 x 348

There is no electronics market sector currently immune from Pb-free. Ask yourself the following questions:

  • Is your company already dealing with Pb-free electronics?
  • Are Pb-free electronics required by your customers?
  • Do you build products for any of the following harsh environments?
    • Aerospace
    • Medical
    • Military
    • Automotive
  • Do your products require a long service life?

If you answered YES to any of these questions, there is a FREE and open global industry consortium available to help you and your company – the Pb-Free Electronics Risk Management (PERM) Council.

PERM Council Mission Statement

The goal of PERM is to provide overarching leadership and coordination of government and industry Pb-free electronics risk management activities to leverage the commercial supply chain for the aerospace, defense and high performance electronics communities.

PERM Council responsibilities include:

  • Facilitate long-term aerospace, defense and high-performance electronics strategies and tactics to effectively deal with Pb-free electronics issues
  • Develop and coordinate risk management approaches for the transition to Pb-free electronics that maintains:
    • safety
    • performance
    • reliability
    • affordability

PERM Council Group  

PERM is organized to provide industry leadership. The PERM Council, like all of the IPC Committees, uses IPC WORKS, a document management system which allows Council members to create, revise, and distribute documents in real-time fashion among these task teams:



Upcoming PERM Council Meeting Dates

The Council discusses lead-free conversion issues related to the safety, performance, reliability and affordability of electronics in the aerospace, defense, medical and other high-performance markets at several technical meetings throughout the year.  Upcoming PERM meeting dates include the following:

Tin Whisker Risk Model Spreadsheet

Developed by BAE Systems under funding from the DoD Strategic Environmental Research Program (SERDP), a Tin Whisker Risk Model Spreadsheet has been developed that can be used to calculated the expected number of tin whisker shorts on one or more leaded components, based on user-specified part and lead geometry, whisker density, tin whisker length distribution, applied voltage, and conformal coating coverage.  This tool is being provided by the University of Maryland’s Center for Advanced Life Cycle Engineering (CALCE) and can be accessed at https://web.calce.umd.edu/tin-whiskers/spreadsheet/

PERM Documentation and Specifications

The output of PERM participants has led to the generation of effective working documents, issues papers and direct communication with U.S. Department of Defense (DoD) officials as well as industry leaders.
