QC Production Test for VFAT3 Chips

CMS is planning to install GE1/1 chamber using GEM concept during LS2 as part of the Muon upgrade for High Luminosity Operation at the LHC. The front-end VFAT3 ASIC will be used to read signals from GEM detectors. VFAT3 together with its associated hybrid PCB has been produced in volume. This report describes the operation of a custom test bench for the production Quality Control (QC) of the VFAT3 hybrids. Each VFAT3 have to be checked thoroughly through 14 crucial tests including performances measurement and calibration. The data of the test is then analyzed using Python, Spyder IDE. During 2 months of CERN summer student program 2019, I contributed to the upgrades of the statistical analysis program as well as to 67.7% completion of total VFAT3 test.
