  1. SWEA Product Assurance SWEA Peer Review March 28-29, 2011 IRAP, Toulouse

  2. Introduction Applicable & Reference documents Questions from last PR PA/QA implementation Reliability and Safety/Hazards EEE and M&P Material Review Status EIDP PA/QA Presentation Outline 2

  3. PA / QA - Introduction • ECSS standards are used as a guideline in IRAP projects. • GSFC and SSL documents have been accounted for. • PA plan has been updated according to comment made by D. Curtis: corrected quality grade from level 3 to level 2. 3

  4. Applicable & Reference documents 4

  5. Questions from last peer review • Prohibited materials (section 12.13.1): Pure tin (Sn), cadmium (Cd), and zinc (Zn) are not used. • Solder flux used: ROL0 according to ECSS-Q-ST-70-08C 5

  6. PA/QA implementation (1/2) PA and QA activities are implemented following the SWEA Performance Assurance Plan. SWEA-AP-0044-CESR_PAP_1.2 Internal PA reporting is done on a monthly basis. External PA reporting is done with project reporting. Local PA manager is registered to ESA alert system and receives additional CNES EEE alerts. Participation to GIDEP is not possible but received alerts will be accounted for. 6

  7. PA/QA implementation (2/2) • Risks and critical items are managed w.r.t. ECSS-M-ST-80C and ECSS-Q-ST-10-04C. • Any non-conformance will be managed according to ECSS-Q-ST-10-09. • Documentation is managed with Baghera, a dedicated documentation management system. • Configuration control is also managed with Baghera. 7

  8. Reliability is based on studies performed for SWEA-STEREO. No possible failure propagation will be allowed in SWEA design. Hazards identification process has been carried out. High voltages exist but there is no exposure. NEA (non-explosive actuators) are used but are not exposed (unintended actuation might cause contamination, enable/ disable plugs will be used)  no hazard is identified Reliability Safety/Hazards 8

  9. EEE M&P • Both Parts Control Program and Materials and Processes Control Program are incorporated in the Performance Assurance Plan. • All requirements in chapters 11 and 12 of MAR are taken into account. 9

  10. Materials review status 10

  11. Particular & Molecular Contamination These are dealt with as part of normal work. IRAP having contamination and ESD sensitive parts, the general way of work which is implemented at IRAP covers the given requirements. • MCPs to be 500A • Overall cleaning at level VC-HS. • Additional inspection with UV lamp. 11

  12. End Item Data Package (1/2) • Acceptance testing (as run) procedures and reports including total number of failure free testing • Environmental Testing (as run) reports • Final Assembly Work Order • Material Certification or Analysis Forms • Waivers, Deviations or MUAs • As-built EEE parts list • As-built materials list (ABML) • End Item Inspection Report 12

  13. End Item Data Package (2/2) • Nonconformance or problem/failure reports and corrective action summaries • List of Open items or one-time occurrences • As-built final assembly drawing • Photographic documentation of all flight hardware per section 2.3 • Any pertinent analyses (mechanical, electrical, reliability, stress, thermal, worst case) • As-built configuration list (Item, Manufacturer, Model, etc) • Certificate of Compliance signed by management • PWB Coupon Results 13
