Published Date: 04/29/1998


The integrated-circuit (IC) industry is converting to nickel/palladium (Ni/Pd)-finished leadframes for assembly of ICs. To dateTexas Instruments (TI) has over 20 billion Ni/Pd ICs in the field.Users of IC components need to know the maximum length of time that components can be stored before being soldered. The goal of this study was to predict shelf life of Ni/Pd-finished components by expos
