Environmental Compliance Parameter Conditions Mechanical Shock MIL-STD-202, Method 2002 Mechanical Vibration MIL-STD-883, Method 2007 Temperature Cycle MIL-STD-883, Method 1010 Gross and Fine Leak MIL-STD-883, Method 1014 Resistance to Solvents MIL-STD-202, Method 215 Moisture Sensitivity Level MSL1 Handling Precautions Table 5. ESD Ratings Model Minimum Human Body Model 2000V Charged Device Model 500V Machine Model 200 V Although ESD protection circuitry has been designed into the VM-840, 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. Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow conditions. Figure 6 shows max temperatures and lower temperatures can also be used e.g. peak temperature of 220C. Suggested IR Profile Figure 4 Table 6.
