1. Uli Schäfer 1 JEM: Status and plans Pre-Production modules Status Plans

2. Uli Schäfer 2 Sum processor XC2V2000 Jet processor XC2V3000 4 input modules (IM) v1.1 (XC2V1500, SCAN921260) TTCdec module Control Module (CM) v1.3 (home assembled) CAN VME control Fan-out of configuration lines G-link readout module (RM) v1.2 Pre-production: JEM1.3

3. Uli Schäfer 3 Pre-production module status (pre B’ham) 4 JEMs 1.3 had been ordered 01/2006 and were delivered 05/2006 16 input modules 1.2 had been ordered 01/2006 and were delivered 05/2006 (first delivery in April, re-work) 4 readout modules 1.2 had been ordered 01/2006 and were delivered 03/2006 4 control modules 1.3 home assembled Problems with 1 JEM (1 FIO line broken ?), 4 input modules (B/Scan errors), 1 RM (ROI link broken), 1 CM  So far: yield : 75 %

4. Uli Schäfer 4 “full crate” pre-production tests at B’ham Test session June 19-23 : 3 JEM 1.3 main boards with input modules 1.1 1 JEM 1.2 main boards with input modules 1.0 2 JEM 1.0 main boards with input modules 1.0 Problems with one JEM1.3 not configuring up… The other ones were run successfully and were read out into a DSS. JEM CAN signals observed in TCM. But: still not too happy with triple-ease mechanics: front extrusions wearing out. Problems inserting new modules between 2 ‘old’ ones. Might be due to EMI shields…

5. Uli Schäfer 5 Post Brum 2 “broken” JEMs 1.3 checked again in Mainz (June 23 – 27): FIO error not confirmed Configuration problem traced back to resistive short of JTAG lines to SMB bus lines on one input module  yield might be higher than stated above  need to improve cleaning procedure at manufacturer

6. Uli Schäfer 6 Plans Bruno currently working on JTAG test adapters Confirm that problems seen on JEM1.3 were due to insufficient cleaning only. Confirm that with new JEMs only the mechanics issue disappears Have another “full crate” test session very soon Do we need any special setup to do FIO and JEM/CMM tests at high statistics ? Do we need more results on the CAN readout ? Hope to press the button for volume production in about 3 weeks time (?) Difficult to estimate time required for volume production, given the bad track record Should we opt for minimum production time or should we rather suggest production in two batches ? Need to talk to manufacturer to make sure we have got 32 fully working modules for installation. Re-work / later availability of spare modules possibly acceptable…
