Strain gage testing allows for objective analysis of the strain and strain rate levels to which a surface mount package may be subjected to during assembly, test and operation. Excessive strain can result in various failure modes for different solder alloys, package types, surface finishes or laminate materials. This document describes specific guidelines for strain gage testing during the printed...

Developed by the OEM council of the IPC, the MQP sets the standard for assessing PWB manufacturer capabilities and allows PCB manufacturers to more easily satisfy customer requirements. This document eases auditing processes and reduces the frequency of audits, thereby decreasing paperwork and enhancing manufacturer effectiveness. Revision A consists of a single, easy to use electronic file...

IPC-1782B establishes minimum requirements for manufacturing and supply chain traceability based on perceived risk. IPC-1782B applies to all products, processes, assemblies, parts, components, equipment used and other items as defined by users and suppliers in the manufacture of printed board assemblies, as well as mechanical assembly and printed board fabrication. IPC-1782B is applicable both for...

Covers the requirements for copper/invar/copper (CIC), copper/molybdenum/ copper (CMC) and three-layer composites for use in electronic applications.

This document is the product of the IPC Electrochemical Migration (ECM) Task Group.
