Abstract :
Knowledge of thermo-mechanical strains in plated-through holes, complemented by an understanding of failure mechanics, yields valuable information about the effect of materials, design and process parameters on product reliability potential. A technique is described for measuring central barrel strain and surface land rotation for plated-through-holes during thermal transients.
