Tin Whisker Mitigation Process

As a leading producer of high-reliability passive components for use in military, aerospace and medical electronic devices AEM has devised an aerospace qualified tin/lead conversion process designed to virtually eliminate the formation on Tin Whisker on surface mount terminations

This process can be applicable to capacitors, inductors, resistors, and many other molded body passive and active surface-mount component types
