ESD protection

New electrostatic discharge (ESD) packaging on piezoresistive pressure sensors
Added Protection from Potential Handling Damage Ensures Greater Measurement Integrity

Endevco® has announced the addition of value added electrostatic discharge packaging (ESD) on all of its piezoresistive pressure sensor lines.

Within typical testing environments, ESD is a commonly identified cause of difficult-to-duplicate or unpredictable sensor and instrumentation malfunctions, false measurement readings and compromised data integrity. This can also result in large amounts of unplanned downtime, as the random effects of ESD may turn up inconclusive during a typical Failure Analysis (FA). Common sources of ESD can be direct contact with a charged source, or by electric fields emanating from charged objects, which induce a charge on sensitive non-grounded items. Thus, many companies have implemented formalized in-house ESD control programs and procedures, applied to all steps of the manufacturing and testing process, to reduce harmful effects of static electricity on critical components.

New Endevco® ESD packaging supports these types of programs, while further protecting highly sensitive pressure sensors from handling damage, prior to reaching their intended application environment. Packaging includes a static shielded bag with ESD sensitive marketing, labeled ESD foam inside of a hard plastic case, and inclusion of the calibration certificate within the case, to ensure that it travels with the sensor. With these enhancements, a customer’s shipping and receiving, QA, inventory and other personnel are able to quickly identify an item as ESD sensitive, and utilize appropriate precautions. In addition, the packaging provides a space-saving ESD bag for further storage protection.
