Automotive firm gives thumbs up to contact unit holder

Multitest’s Quick Lock Contact Unit Holder (CUH) for ecoAMP and DuraKelvin Plunge-to-Board set-ups on the MT9928 gravity feed handler has been adopted as the standard mounting solution by one of Multitest’s largest automotive customers. Quick Lock demonstrated substantial reductions in maintenance, debugging, and repair times.

The Quick Lock CUH allows for quick and easy socket replacement. No tools are required and a complete set of eight sockets can be replaced in under two minutes.

A standard mounting would require removing the thermal insulation to get access to the screws, which in turn would then need to be removed with the appropriate tools.

In the Quick Lock CUH the screws have been replaced by small levers, which are easily accessed without any hindrance and can be locked and unlocked without any tools.

The Contact Unit Holder works at full temperature range. Its design ensures mechanical stability of the locked contactors and also absorbs the plunger force from the handler to reduce DUT board wear

Frank Roehrl, Project Manager, explains: “The Quick Lock CUH responds to key test socket challenges – shortening test cell downtimes due to maintenance and reducing the wear of a critical test cell component. In developing this solution, we relied upon the deep experience of our team in mechanical and thermal simulations. Additionally, we evaluated test runs deploying a thermal camera and performed extensive board wear tests in our engineering lab. Bringing all this together enables us to provide a solution for our customers to substantially increase their test cell performance.”
