Space Enhanced Plastic Products (SEP) devices are a cost-effective radiation-tolerant solution developed by TI to address, among others, shorter duration high volume small satellites and New Space applications, offering the following advantages over standard catalogue products:
- QMLV like flow:
- Wafer lot acceptance using MIL-PRF-38535 QML Class V as a baseline.
- Controlled baseline with one wafer fab, one assembly site, one material set.
- Traceability
- Robust material set:
- Optimized material set with die-attach, mould compound, lead frame, and bond wire all selected to maximize reliability.
- No high tin (>97% Sn) construction including terminations (SnAgCu solder balls and Matte-Sn plating) or internal package components (die bumps or substrate plating).
- No copper bond wire. Product is either flip-chip mounted (no bond wire) or uses gold bond wire.
- Enhanced products reliability and qualification (HAST, extended Temp, meets MIL-PRF-38535 Class N
- Additional assembly processing including 100% temperature cycle or 100% single-pass reflow simulation in lieu of temperature cycle.
- Characterization over the target temperature range (-55°C to +125°C).
- Parametric testing is standard at both room and high temperatures with guardbands to assure datasheet limits at cold temperature.
- Wafer lot acceptance using MIL-PRF-38535 QML Class V as a baseline.
- Outgassing qualification for each product per ASTM E-595.
- Qualification to SMC-SO-11.
- Assembly lot acceptance including x-ray sampling and CSAM sampling.
Characterization for total dose and single event radiation performance:
- Single characterization up to 30krad (ELDRS free)
- Radiation Lot Acceptance Testing (Group E) to 20krad TID for each wafer lot per MIL-STD-883
- SEL Characterization to 43 MeV-c m2/mg.

Since 2000 in Alter Technology, as EEE Parts Engineer, first in the Engineering and Materials Management Department, has given technical support to customers in many different space programmes. And later on, as Coordinator of the Parts Engineering and Purchasing Department, has been in charge of guarantee the proper EEE Parts selection/definition/testing to ensure the technical/schedule/budget compliance to projects requirements. Currently and since 2017 is leading the Technical Content Maintenance Team of doEEEt platform.
With the continuous maintenance of the platform technical content, doEEEt provides to the space community the most updated and complete information about Hi-Rel EEE components, related documentation, and reports, as well as any associated procurement and testing activities.
