The conditions a device can withstand are well understood and devices can be subjected to the profile in figure above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux is activated, a ramp up to 183° C which is the eutectic temperature of Sn/Pb and a gradual cool down. The time above 183° C should not exceed 60 seconds and the peak temperature should be no more than 220° C for 10 seconds. The Jtypes are 100% screened for hermeticity so an aqueous wash is not an issue.

VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD thresholds are dependent on the circuit parameters used to define the model. Although no industry wide standard has been adopted for the CDM, a standard HBM of resistance = 1.5Kohms and capacitance = 100pF is widely used and therefore can be used for comparison purposes.
