11. CMS FRANCE MAI 2004 h.mathez 11 MECHANICAL PROBLEMS (0) Socket : with microstrip, same technology as previous (FPPA) package EDQUAD 52 pins ASAT New problems with Aries socket and ASAT TQFP100 package oThe socket was tested with Atlantic package at ARIES house : Some devices present an excess of plastic in the corners  Some small chips goes under the microstrip : no electrical contact, the MGPA does not work !  Microstrips could be twisted due to this small chips, the MGPA does not work ! NO problems Solutions  Very carefully clean up the PCB and the socket

16. CMS FRANCE MAI 2004 h.mathez 16 ASAT Europe business contact is currently overloaded Microtec and Edgetek appear to be very good candidates Strength Weakness Microtec Edgetek Experienced Already used inside CERN Flexibility ? IN2P3 partner for small quantities French company Flexibility for custom services Price Background for high volume production TESTING HOUSES SUM UP (1) We would suggest to give to Microtec the MGPA production tests

17. CMS FRANCE MAI 2004 h.mathez 17 TESTING CONCLUSION (MEETING 10 MAY CERN) Buffer Testing House : EDGETEK Forecast Schedule :  100 buffers for June 10 th  5000 buffers for July 15 th MGPA Microtec or Edgetek but we are waiting the Asat’s answer Edgetek seems to be the best way to test the MGPA Forecast Schedule :  1700 MGPA for july 15 th  Start testing production : middle of September
