    Handling Precautions
    Although ESD protection circuitry has been designed into the the VCC1, 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.

    Suggested IR profile
    Devices are built using lead free epoxy and can also be subjected to standard lead free IR reflow
    conditions, Table 9 shows max temperatures and lower temperatures can also be used e.g. peak
    temperature of 220C.
