Environmental testing - Part 2-82: Tests - Test Xw1: Whisker test methods for components and parts used in electronic assemblies

This part of IEC 60068 specifies tests for the whiskering propensity of surface finishes of*electric or electronic components and mechanical parts like e.g. punched/stamped parts (as,*for example, jumpers, electrostatic discharge protection shields, mechanical fixations, press-*fit pins and other mechanical parts used in electronic assemblie) representing the finished*stage, with tin or tin-alloy finish (changes of physical dimensions of mold compound, plastic*etc. during required test flow will not be considered or assessed). The test methods have*been developed by using a knowledge-based approach.*This standard can also be used at sub-suppliers like plating shops, stamping shops or other*service providers to assure a consistent surface quality within the supply chain.*This test method is employed by a relevant specification (component or application*specification) for components covered therein with defined acceptance criteria.*The tests described in this standard are applicable for initial qualification, monitoring*according to clause 7 and changes of technology or manufacturing processes on existing*surfaces according to clause 9 .**The mating area of connectors is not covered by this test method.IEC 60512-16-21 applies to*the mating areas of connectors.
