FAQ
What qualification tiers does Teledyne HiRel offer?
• Teledyne HiRel supports the full range of qualification tiers from commercial screening through full QML-V hermetic certification.
• Standard tiers include Space COTS, MIL-PRF-38534 Class H, MIL-PRF-38535 Class B, Q, and V, MIL-STD-750, and MIL-STD-883.
• Custom SCD qualification flows can be developed for program-specific requirements that fall between standard tiers.
What is a custom Source Control Document (SCD) qualification flow?
• A custom SCD is a program-specific qualification document agreed between Teledyne HiRel and the program team that defines tailored screening steps.
• Steps can be added or removed from standard qualification sequences to match the program's reliability objectives, cost constraints, and schedule.
• Custom SCDs are particularly valuable for Space COTS programs where the standard commercial qualification is insufficient but full QML-V is unaffordable.
What screening steps are included in a typical Teledyne HiRel qualification flow?
• A typical flow covers wafer lot acceptance, die attach, wire bond, internal visual inspection, seal, constant acceleration, temperature cycling, PIND, pre-burn-in electrical test, burn-in, post-burn-in electrical test, gross leak, fine leak, radiographic inspection, external visual, and final electrical test.
• The Milpitas facility is equipped with shake, rattle and roll equipment, ovens, test board design capability, and burn-in jigs to execute these steps.
• Specific steps and parameters are defined in the program SCD or applicable MIL standard.
What certifications does Teledyne HiRel hold?
• Certifications include AS9100C, ISO 9001:2015, DOD DMEA Trusted Supplier, ITAR Registered, and NASA PEM-INST-001.
• MIL qualification capabilities cover MIL-PRF-38534 Class H, MIL-PRF-38535 Class B/Q/V, MIL-STD-750, and MIL-STD-883.
• The Lewisburg, Tennessee facility operates as a DOD Trusted Supplier with over 50 years of microelectronics assembly experience.
Can Teledyne HiRel qualify or test customer-furnished devices?
• Yes. The qualification and test infrastructure can be applied to customer-furnished wafers and packaged devices.
• Services include packaging, test board design, ATE-based production testing at rates of several thousand devices per month, and environmental and radiation screening.
• Sample testing of commercial parts to verify continued suitability is also available.
How does Teledyne HiRel handle radiation testing within a qualification flow?
• Total Ionizing Dose test reports are available for applicable space-grade catalog products.
• Radiation test steps can be incorporated into custom SCD qualification flows for programs with specific TID exposure requirements.
• Individual devices are tracked from wafer through all subsequent stages with a full documentation trail to support radiation lot acceptance.
What is the difference between Space COTS and QML-V qualification?
• Space COTS uses a tailored screening flow with reduced cost and schedule compared to full QML-V, suited to programs with shorter mission durations or lower radiation environments.
• QML-V (MIL-PRF-38535 Class V) requires hermetic packaging, full QML program compliance, and the most extensive screening and documentation.
• Teledyne HiRel advises program teams on where qualification investment makes sense relative to the mission parameters, risk tolerance, and budget.
What RF test capability does Teledyne HiRel have for production testing?
• RF characterization and production test capability scales to 65 GHz with ATE-based testing and data reporting summaries.
• Wafer-level probing is available to 70 GHz using Cascade microwave probes.
• Test types include S-parameters, phase noise, noise figure, EVM, ACPR, and IIP3.
