  • Materials notes

    • Receiving inspection will be performed on all materials supplied by the customer using documents supplied

    • All discrepancies shall be documented and relayed to the customer in 24 hours from their discovery

    • All moisture sensitive materials used in the manufacturing of the TEM will be stored and handled in accordance with GTC-2025A -Moisture Sensitive Component Handling, Use of Dry Room Storage.

    • Materials issued in the production of TEM/TPS for assembly will be traced in a manner that would enable traceability from the assy S/N to the individual part /piece and production lot/date code.

    • Every TEM and TPS assembly will have its own traveler issued to facilitate traceability of IC serial numbers installed on that particular CCA.

  • SMT area notes

    • Operators will record all IC serial numbers and location at which they are installed on a particular CAA for traceability purposes. All IC’s used in the production of TEM assemblies are serialized.

    • Operators will inspect and measure the solder paste height on every print at 3 predetermined locations. The results will be recorded in the SMT printer log along w the printing parameters

Issues concerns

Issues/Concerns

  • Actel FPGAs pose a reliability concern

  • Maxim 724 is rated at 2.6-32.0V, we are biasing to operating at 1.5V. Parts were not screened for this application, PCB reviewing screening requirements.
