Handling Precautions

Although ESD protection circuitry has been designed into the the VCS3, 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 7 shows max temperatures and lower temperatures can also be used e.g. peak

temperature of 220C.
