Ensure that your shielded bags protect the sensitive devices they exist to serve. ElectroTech Systems’ 4431 provides a reliable measure of how well a bag shields its contents from an external ESD event. This turnkey system administers a HBM pulse to the outside of the bag and makes a calibrated measurement of energy detected inside the bag. User-friendly 4431 Test Manager software schedules multiple tests on multiple samples and provides both printed and graphical reports of the results. The 4431T allows you to verify that bags are accomplishing their stated purpose, choose between bag materials and design, as well as monitor production variation and overall shielding effectiveness.
