VI employs a human body model and a charged-device model (CDM) for ESD susceptibility testing and design protection evaluation. ESD Ratings Model Human Body Model Charged Device Model Minimum 1500 V 1000 V Conditions MIL-STD 883, Method 3015 JESD 22-C101 Recommended Solder Reflow Profile 220 Temperature (Deg C) 183 150 60 60-90 45-60 Time (s) VI qualification includes aging at various extreme temperatures, shock and vibration, temperature cycling, and IR reflow simulation. The conditions a device can withstand are well understood and devices can be subjected to the profile above. This profile shows a ramp up condition to prevent thermal shock, a preheat period in which the flux is activated, a ramp up to 183C which is the reflow temperature of Sn/Pb eutectic, and a gradual cool down. The time above 183C should not exceed 60 seconds and the peak temperature should be no more than 220C for 10 seconds. The VS-500's are hermetically sealed so an aqueous wash is not an issue.
