Developement of automated quality tests for the RD51 VMM3a Hybrid — •Finn Jaekel, Jochen Kaminski, Michael Lupberger, and Patrick Schwäbig — Physikalisches Institut, Universität Bonn

The Scalable Readout System of the RD51 Collaboration is a diverse readout system, which is used in many areas in the developement of gaseous detectors. It supports different front-end chips like Timepix, VFAT or APV25 and contains the complete readout-chain to transfer data between the detector and the computer. Until recently the APV25 ASIC was frequently used. As nowadays it is not produced anymore, a new front end chip - the VMM ASIC (developed for the ATLAS New Small Wheels upgrade) - was developed and integrated into the scalable readout system.

The project currently is on its way from developement to mass production. There is already strong interest to use the readout system for a wide variety of experiments and research projects. Especially the front-end printed circuit board with the VMM chip, called hybrid, of which large amounts will be produced, requires automated quality assurance.

In this talk quality criteria, developement of an automated testing procedure, as well as first results of these quality tests will be presented.
