Tin whisker mitigation documents released

JEDEC and the International Electronics Manufacturing Initiative (iNEMI) have released two documents intended to help manufacturers reduce the risk of tin whisker growth in lead-free products. The first is JEDEC standard JESD201, “Environmental Acceptance Requirements for Tin Whisker Susceptibility for Tin and Tin Alloy Surface Finishes,” and the second is a JEDEC/IPC joint publication, JP002, “Current Tin Whiskers Theory and Mitigation Practices Guideline.”

JESD201 – developed by JEDEC’s Subcommittee on Silicon Device Reliability Qualification and Monitoring and the iNEMI Tin Whisker User Group – was designed to provide a uniform environmental acceptance testing and reporting methodology for tin whisker susceptibility of tin and tin alloy surface finishes in the electronics industry.

JP002 – developed by JEDEC’s Subcommittee on Reliability Test Methods for Packaged Devices, and IPC’s Tin Whiskers Guidelines Task Group, with input from iNEMI’s Tin Whisker Users Group – was designed to provide guidance in understanding the prevalent theories regaqrding tin whisker formation, the driving force behind tin whisker growth and mitigation practices used to minimize whiskers.
