IPC 9708 – Test Methods for Characterization of Printed Board Assembly Pad Cratering

Mechanical bend and shock tests are routinely performed on SMT assemblies to ensure that they can sustain anticipated production, handling and end use conditions. The strains and strain rates applied to SMT assemblies during bend and shock testing can lead to a variety of failure modes in the vicinity of the solder joints. This document provides test methods to evaluate the susceptibility of printed board assembly (PBA) materials and designs to cohesive dielectric failure underneath surface mount technology (SMT) attach pads. The test methods, which include pin-pull, ball-pull, and ball shear, can be used to rank order and compare different printed board materials and design parameters.
