The vacuum operated Test Fixtures for the Digitaltest MTS 100/200/300 Test Systems consist of a base housing and an INGUN vacuum cassette. The cassette is hinged to enable easy access to the receptacles and wiring during vacuum actuation and PC board contacting.

The Interface Frame for the MTS100 test system is mounted in the rear section of the housing, and the Interface Panel for the MTS 200 test system in the base plate of the housing. See photos!

The Probe Plate is made of standard 10 mm hard-paper laminate (CEM-1) material. The Top Plate is made of 8 mm epoxy hard-paper laminate and coated both sides with an anti-static coating. The vacuum sealing within the cassette is achieved using the renowned INGUN wearfree V-profile seal.

When contacting PC boards with open vias and other open areas, we recommend the use of either a Vacuumfree Zone sealing method (with a pressure-frame unit and push rods) or the use of a vacuum-sealed cover (with pushrods). Furthermore, Pressure-Frame Units for the Assembly of Opens Detection and Vectorless Testing Components are available for all standard fixture sizes.

The vacuum Test Fixtures are assembled on a base housing, which is matched up to the Digitaltest Test System. The vacuum cassette is hinged to the housing. The Digitaltest interface of the Test Fixture is mounted to the base housing.

Due to the position of the Test Fixture being placed towards the front, the VIN 423 is especially user-friendly. When contacting PC-Boards with open vias we recommend the customizing of the vacuum cassette with either a vacuum-free zone and pressure-frame unit or with a vacuum-sealed cover and push-rods. Pressure-Frame Units for customizing with vacuum-free Zones are available for all standard fixture sizes.
