Handling Precautions
Although ESD protection circuitry has been designed into the the VCC6, 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
Table 8 shows max temperatures and lower temperatures can also be used e.g. peak temperature of
220C.
Termination finish is gold over nickel. The VCC6 is hermetically sealed so an aqueous wash is not an
issue.
