TEST METHODS FOR THE MASS-PRODUCTION OF P IEZORESISTIVE ACCELERATION SENSORS

The test of acceleration sensors which are dedicated for the usage as airbag sensors applies high demands on the according production test s ystem. On the one hand the test methods have to reach a high test spee d, to satisfy the extreme throughput conditions. On the other hand the re ale high demands on the measurement accuracy and the measurement sa fety. This article introduces measurement procedures which meet these conflicting demands and which are applied in a production solution. Th e paper discusses the definition of the test parameters of airbag sens ors, the theoretical methods of the signal analysis for their determin ation and the technical solution of the sample system.
