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
The VCC6 has been qualified to meet the JEDEC standard for Pb-Free assembly. The temperatures and
time intervals listed are based on the Pb-Free small body requirements and parameters are listed in Table 7.
The VCC6 is hermetically sealed so an aqueous wash is not an issue.
