Overview Parts & Materials Overview Requirements EEE Parts ID List Procurement Parts Status

Requirements & Specs GSFC 311-INST-001 Instructions for EEE Parts Selection, Screening, Qualification Minimum EEE Parts Criteria for Level 3 = Moderate level of risk, as permitted by cost constrains Parts in compliance with 311-INST-001, Level 3 (Grade 3) requirements and Standard parts Use of GSFC PPL 21 (GSFC Preferred Parts List), design permitting Non-standard EEE parts will require at a minimum: Plastic Encapsulated Microcircuits (PEM) Selection, Screening, and Qualification (NASA/TP-2003-212244, PEM-INST-001) PIND per MIL-STD-750 and MIL-STD883, required for cavity devises Impose on manufacture, if possible When needed, have DESC approved test facility perform testing

Requirements & Specs (continued) Customer Source Inspection DPA performed for complex or known problem devices Preconditioning, HAST, and CSAM Testing Radiation Testing Total Ionizing Dose Requirement is 66Krads (si) - Review existing test data from GSFC, JPL, and manufacturer - Review NASA “where used” historical data Parts can be used, if data and or orbit requirements equal or exceed THEMIS requirements Cobalt 60, TID testing will be performed as needed SEE use existing data or historical use (similarity) - Whenever possible designers will use latchup immune devices

Requirements & Specs (continued) Flowdown Performance Assurance Implementation Plan requirements on subcontractors Parts Control Board (PCB) PCB members are: Themis QA, Design Engineer, and Themis Project manager, or representative PCB shall review EEE part for: Testing, Screening, and Qualification Failures Alerts (e.g., GIDEP) Review Non-Standard Parts Requirements

EEE Parts ID List UCB/SSL QA will maintain an EEE Parts Identification List (PIL) The PIL will contain: Manufacturer’s generic part number Military Part Number or SCD number Manufacturer(s) Where used (unique assembly) / Quantity Quantity used Quantity ordered Lot/Date Code Radiation Status (TID/SEL) Alert Status Comments

Procurement Parts will be procured to an approved Parts List. Schedule permitting, will procure common buy. Procurement of devices will be based upon design engineer’s confidence-of-use factor of 70%. Unique, high-dollar items will be based on a 90%-100% confidence level. Minimum Attrition / Spares factor of 20%-30% will be applied to flight procurement quantities. ETU and Flight unit Procurement will run concurrently
