13 Jan 2005 Warm Electronics Qualification Status2 Warm Electronics Overview

PACS IQR13 Jan 2005 Warm Electronics Qualification Status3 Built Standard of WE Items I

PACS IQR13 Jan 2005 Warm Electronics Qualification Status4 Built Standard of WE Items II PACS AVM WE integrated on SVM Panel Simulator at Astrium (QM1 BOLC ext. PSU not shown) Status:

PACS IQR13 Jan 2005 Warm Electronics Qualification Status5 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status6 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status7 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status8 Electrical Interface Qualification Status : Power Power Budget Is DECMEC Power Consumption final? Possible changes due to Heater / Flasher Implementation. Slight Increase of SPU Power. CR released

PACS IQR13 Jan 2005 Warm Electronics Qualification Status9 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 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)

PACS IQR13 Jan 2005 Warm Electronics Qualification Status10 EMC / ESD Qualification Status : AVM Matrix

PACS IQR13 Jan 2005 Warm Electronics Qualification Status11 EMC / ESD Qualification Status : EQM /QM EQM IST Testing - Only RS tests foreseen, acc. HP-2-ASED-PL 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status12 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status13 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)

PACS IQR13 Jan 2005 Warm Electronics Qualification Status14 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

PACS IQR13 Jan 2005 Warm Electronics Qualification Status15 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)
