Advanced Packaging / Hermetic
Sealed, tested, qualified.
Hermetic packaging for hardware that has to survive the field – sealed cavities, leak-tested to MIL-STD, and qualified with data you can hand to a program office. One engineering team, on US soil.
/ Fine & gross leak / MIL-STD screening / ITAR-aware / US-soil
Proof, from real builds
Yield on 50 aviation interposers · sealed and screened
MEMS assemblies · panel-level · 100% yield · no post-attach clean
Placement at 3σ · the build accuracy a tight seal demands
Qualification data, leak-rate detail, and full build records available under NDA.
Hermetic capability
Seal it. Then prove it.
A hermetic claim is only worth the leak rate behind it. We seal the cavity, test it, and document the result so the package is defensible – not assumed.
Sealing is matched to the device: sensors and MEMS that need a stable cavity, optoelectronics that cannot tolerate moisture on the active surface, and RF modules where a wet cavity shifts performance. We build to advanced-packaging tolerances, then verify hermeticity before anything ships.
- 01Hermetic seal of cavity packages – controlled, dry, contaminant-free interior
- 02Fine leak test by helium tracer to MIL-STD method
- 03Gross leak test to confirm there is no large breach
- 04Sealing for sensors, MEMS, and optoelectronics
- 05Hermetic RF and mixed-signal modules on AlN and ceramic carriers
- 06Build records that trace each seal back to its leak result
Measured leak rate · documented method · traceable to the unit · ready for a program review.
A wet cavity is a failure waiting.
Moisture is the enemy of every device you cannot service in the field.
Trapped water vapor drives corrosion, dendrite growth, and parametric drift. On a satellite payload, an implant, or a missile seeker, that drift is the difference between mission life and an early return. A real hermetic seal keeps the cavity dry across temperature, vibration, and years – so the device that passes at acceptance still passes at end of life.
We treat the seal as a reliability decision, not a closeout step. Test it now, or field it and find out later.
Test & qualification
Screened to a standard.
MIL-STD screening
Visual, electrical, and hermetic screening run against MIL-STD methods, so the package speaks the language your program office already audits to.
Thermal cycling
Cycling stresses the seal across temperature extremes to surface weak joints before the field does. See failure analysis & reliability for the full reliability flow.
Leak verification
Fine and gross leak test before and after stress, with the measured rate recorded against each unit. The seal is proven, not presumed.
