Handling Precautions

Although ESD protection circuitry has been designed into the VTD3, 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 7 shows max temperatures and lower peak temperatures can also be used e.g. peak temperature of

230-240°C. The VTD3 should not be subjected to a wash process that will immerse it in solvents – a no

clean process is recommended.
