The VX-705 family is capable of meeting the following qualification tests: Table 4. Environmental Compliance Parameter Conditions Mechanical Shock MIL-STD-883, Method 2002 Mechanical Vibration MIL-STD-883, Method 2007 Solderability MIL-STD-883, Method 2003 Gross and Fine Leak MIL-STD-883, Method 1014 Resistance to Solvents MIL-STD-883, Method 2015 Moisture Sensitivity Level MSL 1 Contact Pads Gold over Nickel Handling Precautions Although ESD protection circuitry has been designed into the VX-705 proper precautions should be taken when handling and mounting. VI employs a human body model (HBM) and a charged device model (CDM) for ESD susceptibility testing and design protection evaluation. Table 5.
