Warm Electronics Overview



Built Standard of WE Items I



Built Standard of WE Items IIPACS AVM WE integrated on SVM Panel Simulator at Astrium (QM1 BOLC ext. PSU not shown)

Status: 21.12.2004



Thermal Qualification Status

• AVM / STM WE Unit testing

- STM BOLC: TV test for design validation : OK

- BOLC PSU sub-unit thermally tested : OK- As agreed, no tests were done with other units

• CQM / AVM ILT- No tests were foreseen and done

• QM / PFM WE Units- Simulations and Analysis done for all units- Full qualification programs are currently ongoing- First results for QM SPU available



Electrical Interface Qualification Status : AVM

• AVM WE Unit testing by sub-contractor

- No qualification tests foreseen on sub-contractor level for delivered units- no VCD available as no test foreseen

• AVM WE Unit testing by MPE

- Inrush current measurements for DPU, SPU : compliant

- Spectrometer Groundings tested during ILT- ICC data analysis still missing for final decisions



Electrical Interface Qualification Status : QM / PFM

• QM WE Units testing

- Full applicable testing on sub-unit level contractually agreed

- First results for QM SPU available : NCRs for Bonding R and PROM contents- Nothing available yet for other units- Qualification Test Programs are ongoing- NA for WIH

• PFM WE Units testing

- Full applicable testing on sub-unit level contractually agreed

- All testing necessary and required prior to delivery to MPE- PFM WE Units should not be accepted without completed Test Reports

Is DECMEC Power Consumption final? Possible changes due to Heater / Flasher Implementation.

Slight Increase of SPU Power. CR released 12.01.2005



EMC / ESD Qualification Status : AVM

• AVM WE Unit testing

- No tests conducted on sub-contractor level for delivered units of DPU, SPU, DECMEC and BOLC, NA for WIH

• CQM / AVM ILT

- Full applicable test program done, given in EMC test specification PACS- ME-PL-015, Issue 1.2- As run Test procedure PACS-ME-PL-015, Issue 1.2 available via CR-0020v2- EMC Draft Test Report available, ICC Data analysis still missing- Some NCRs, RfW raised or re-issued- ESD testing not done (high risk)- Test and Compliance Matrix : see next transparency (extract of available Draft Test Report, PACS-ME-TR-038, chapter 3)



EMC / ESD Qualification Status : AVM Matrix



EMC / ESD Qualification Status : EQM /QM

• EQM IST Testing

- Only RS tests foreseen, acc. HP-2-ASED-PL-0037

- ESD testing omission still under discussion and not agreed

• QM WE Units testing

- ALL QM models are NOT deliverable items

- Full applicable testing on sub-unit level contractually agreed and expected- First results for QM SPU available, NCRs for RE-E- Nothing available yet for other units- NA for WIH



EMC / ESD Qualification Status : PFM

• PFM WE Units testing

- Full applicable testing on sub-unit level contractually agreed and expected

• PFM ILT EMC testing

- full applicable testing acc. IID-A, as reflected in PACS-ME-PL-015 with exceptions for ESD and RE/RS-E/H-Field testing

• PFM IST EMC testing

- Only CE tests foreseen, acc. HP-2-ASED-PL-0037



Electrical Design Status : Plans for FM

• DPU AVM to DPU CFM / PFM- Changed PL I/F Board, new design

• BOLC QM1 to BOLC QM2 / PFM- Changed Bandwidth (and other) of Read-out electronics- Several Changes in digital electronics- New PCB designs

• DECMEC AVM to DECMEC QM / PFM - Several changes during and after ILT necessary to provide

functionality and performance • SPU AVM to SPU QM / PFM

- no changes (as far as reported)



Critical Qualification Items I

• WIMA MKS-2 capacitors (not part of WE, are in FPU) : not yet qualified for cryogenic use

• Distribution Board „Evaluation“(not part of WE, FPU) : visit at Board manufacturer „Waltron“ still pending

• Cryo Harness Verification and Compliance Matrix missing

• Agreement on full PFM WE Unit Qualification prior to delivery to MPE

• Risk that DECMEC functionality and performance could shorten the Qualification programme. Additionally the Heater / Flasher Electronics for Photoconductor curing has to be implemented in DECMEC.

• Solution for DPU 1553 Burst Mode Problem pending



Critical Qualification Items II

• Spectrometer Grounding Decision after Data Analysis : Warm-end or Cold-end-Grounding

• Agreement on ESD Testing at the end of EQM IST open• RS-H of Photometer / Bolometer very high• BOLC QM1 with external PS not EMC ILT tested

• BOLC uncontrolled switch-off could damage the bolometers (NCR existing)
