This part of IEC 61163 provides guidance on reliability stress screening techniques and procedures for electronic components. This standard is not, and cannot be, exhaustive due to the rapid rate of developments in the electronics industry. This standard is intended for the use of a) component manufacturers as a guideline, b) component users as a guideline to negotiate with component manufacturers on stress screening requirements or plan a stress screening process in house due to reliability requirements, c) subcontractors who provide stress screening as a service. This standard is not intended to provide test plans for specific electronic components or for delivery of certificates of conformance for batches of components.
