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. Table 4. ESD Ratings M odel Human Body Model Charged Device Model M inimum 1000 1000 Conditions MIL-STD-883 Method 3115 JESD 22-C101 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 5. As the contact pads are gold over nickel, devices can be reflowed at lower temperatures. The VCC6 is hermetically sealed so an aqueous wash is not an issue. Table 5.
