Storage Life for plastic SMT

Storage Life for plastic SMT | 16 January, 2003

Is there documentation showing shelf life for plastic surface mount devices ? This will of course take into consideration that all the nessecary ESD precautions with N2 dry boxes are in use.

There is no documentation like you seek. The life of your part in storage is primarily a function of: * Quality of the part fabrication process. * Ingenuity and diligence you apply in protecting the parts from the environment.

You need to: * Handle and package the parts properly to protect them from degradation. * Store them in a benign environment. * Check the solderability periodically. * Refresh the solderability as required. * Demoisturize parts prior to soldering.
