Test fixture VA 4040

Vacuum test fixtures (VA) are used in industrial production for reliable contacting of printed circuit boards in high quantities and a low number of variants. The parallel contact stroke with a height of several millimetres is generated by means of negative pressure by suction of air into the vacuum zone. To press the test specimen onto the spring-loaded test probes, standard assemblies - so-called vacuum assemblies - are used as vacuum covers, vacuum pressure frame units, additional vacuum contacting, or vacuum drive units to provide ideally adapted assemblies for the test requirements. The vacuum test fixtures can be used for single-stage contacting, dual-stage contacting, top contacting and customisation with vacuum-free zone, are connected to an existing test system, and have the following performance features: •Parallel suction vacuum cassette with established INGUN seal. •Robust, maintenance-friendly design with outstanding service life •Stand-alone system without interchangeable exchangeable kit •Increased ease of use thanks to simple, intuitive handling •Easy access to housing interior thanks to wide opening angle •Available in various versions and sizes •Available with or without test system interface •Service life: > 2,000,000 load cycles (under laboratory conditions) •Comprehensive customisation and installation documentation
