| Applications Sensitive electronic devices are susceptible to damage or degradation by direct electrostatic discharge from personnel or equipment, or by a charged device discharge. The static shielding bag is designed to protect these components from ESD events. Devices may be either voltage or energy sensitive. EIA-541 "Packaging Material Standards for ESD Sensitive Items" defines the measurement of the voltage inside the bag when a 1kV HBM discharge is applied to the outside of the bag. ANSI ESD S11.31 "Evaluating the Performance of Electrostatic Discharge Shielding Bags" defines the measurement of the energy inside the bag when a 1kV Human Body Model discharge is applied. The Model 431 Shielded Bag Test System is a complete instrument that generates the specified ESD pulse across a test bag and detects either the voltage induced onto or the current across a capacitive sensor placed inside the bag. The optional ETS Test Suite Manager Program controls the operation of the Model 431, calculates the energy inside the bag and processes the data in accordance with ESD S11.31. |
