Table 3. Environnemental Compliance Parameter Mechanical Shock Mechanical Vibration Solderability Gross and Fine Leak Resistance to Solvents Conditions MIL-STD-883 Method 2002 MIL-STD-883 Method 2007 MIL-STD-883 Method 2003 MIL-STD-883 Method 1014 MIL-STD-883 Method 2016 Handling Precautions Although ESD protection circuitry has been designed into the the VVC1, proper precautions should be taken when handling and mounting. 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.
