Inside Our Cleanroom: Assembling Hermetic Packages for Precision

Hermetic packages require not only precision sealing, but also an environment free from particulates, outgassing, and ionic contamination. At AHS, cleanroom assembly is a critical step in ensuring mission-critical devices remain sealed, pure, and reliable over decades of use.

What is Cleanroom Assembly?

Cleanroom assembly involves assembling components in a controlled ISO Class 7 (or better) environment with filtered air, pressure regulation, and full gowning procedures. Technicians follow SOPs to minimize particle transfer, moisture, and human error during final assembly.

Common Cleanroom Tasks

• Sealing of ceramic-to-metal and sapphire assemblies
• Pre- and post-cleaning under ASTM F312/ISO 14644 standards
• Wire bonding, welding, and leak testing in contaminant-free zones

Industries Requiring Cleanroom Assembly

• Semiconductor: Vacuum feedthroughs and custom interconnects
• Medical: Implantable and sterilized sensor housings
• Aerospace: Packages exposed to space, altitude, and thermal cycling

Why It Matters

Even microscopic particulates or trace residues can compromise hermetic integrity and long-term performance. Our cleanroom ensures every part we deliver meets the highest standards of cleanliness, traceability, and reliability.

Conclusion

From optical-grade windows to microelectronic sensors, AHS's cleanroom environment ensures every hermetic component is assembled with care, compliance, and confidence.
