Miscellaneous
Minor variations over time may result in electrical damage arising from disturbances in the form of voltages
exceeding the absolute maximum rating when mounting the product in addition to physical damage. The fol-
lowing factors can give rise to these variations:
(1) Electromagnetically-induced noise from industrial power supplies used in mounting reflow, reworking after
mounting, and individual characteristic evaluation (testing) processes
(2) Electromagnetically-induced noise from a solder iron when soldering
In particular, during soldering, take care to ensure that the soldering iron GND (tip potential) has the same po-
tential as the IC GND.
