Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – December TOTFED – TOTEM Front End Driver VME64x Host Board OptoRX Firmware

Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – December TOTFED – Status (1) VME64x Host Board: - 90 produced in PCB Technology Israel (lead free soldering) - 4 pre-series + 47 first batch delivered to CERN, all tested again and 36 equipped with mechanics: - 3 failed the acceptance test in the Lab then: - 9 delivered to TOTEM using in (Lab, H8, IP5, T1, T2); - 12 for TOTEM are in Lab 555 – for mechanics; - 24 delivered to CMS-ES: - 7 returned as bad after a few weeks of using - 1 delivered to Castor; - 18 second batch – expected from PCB

Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – December TOTFED – Status (2) High rate of failed cards!!! - Study of the problem was done – why, where, what? - From PCB Israel we received a letter saying: … Final QC revealed some mis-soldering in few boards (visually inspected) which might be suspected as a process problem. The boards were electrically tested and a high rate of failure was observed. We found around 40 boards failed during functional testing. The main reason is related to some kind of contamination on the pads which reduced solderablity. Unfortunately this failure mode cannot be detected by using X-RAY machine… - We asked for more investigation, then - One board was cut on the BGA pin which shows error

Gueorgui ANTCHEV PH-TOT TOTEM Collaboration Meeting – December TOTFED – Status (5) What next: - PCB Israel will reproduce all cards using lead non-free soldering at their own costs: - expensive components will be recovered from the old cards; - few cheaper components to be ordered; - Extensive use of all available VME64x Host Boards is required
