IONIQ20 : Leak Tester for High Volume Production On the basis of its well-proven concept of production line Quality Control Testers, ATEQ has developed a new leak Tester, designed for the specific requirements of high volume production of plastic parts. This instrument is used for the detection of localized moulding faults, insufficient membrane thickness, perforations, etc…. The IONIQ 20 is based on discharge current measurement and is able to detect defects in the region of 10μm. Applications : Battery pouch cells, plastic bottle caps, plastic packaging, plastic coverings MEASUREMENT PRINCIPLE : * The IONIQ measures the current flowing between a patented charged probe and a ground plate placed under the part to be tested. * In a PASS situation (fig 1): No hole, no weak part, the IONIQ measures a high %. The measured voltage and the nominal voltage are virtually equal. The result is above the reject level, the part has passed the test. * In a FAIL situation (fig 2): The IONIQ measures a low %. The measured voltage is significantly below the nominal voltage. The result is below the reject level, the part has failed the test. * Test limitations: short probe-part-plate distance, electrical insulation from environment. * The IONIQ uses the % of the nominal voltage (which reflects the discharge current), measured on the part as PASS/FAIL level.
