Abstract :
Some typical models used in the assembly of electronic modules are presented along with data establishing the validity of these models. Six cases are examined: two cases of PTH/PWB (plated-through-hole/printed wiring board) model validation: SMT (surface mount technology) reliability prediction using the matrix creep method; prediction of creep rupture times of SMT butt joints; PGA (pin grid array) cracking; and prediction of PWB deflection during BON (bed-of-nails) testing
