In vacuum systems, medical devices, and other contamination-sensitive applications, particle control during assembly is critical. Even minute residue can degrade component performance, compromise reliability, or cause critical product failures post-installation.
Effective cleanroom assembly and sub-assembly require integrated contamination control rather than basic surface cleaning or final packaging. C-Mac International machines and assembles precision technical ceramic components using controlled handling, cleanroom protocol cleaning, and rigorous inspection processes engineered for applications demanding tight dimensional accuracy and strict particulate control.
Our Cleanroom Assembly & Sub-Assembly Capabilities
We build complete sub-assemblies inside controlled environments, not just individual components. This matters for medical and semiconductor programs, where parts move directly from our facility into sensitive equipment.
Our facility provides comprehensive sub-assembly services in controlled environments to prevent particulate contamination throughout production. We support critical medical and semiconductor programs through the following core capabilities:
- Multi-part integration. Joining ceramic-to-ceramic and ceramic-to-metal components into finished, precision sub-assemblies.
- Contamination control. Enforcing strict gowning protocols, HEPA-filtered air management, and continuous particle monitoring.
- Documented standard operating procedures. Tracking every build stage with written SOPs to guarantee lot-to-lot repeatability.
- Clean packaging. Sealing finished sub-assemblies in certified clean conditions to arrive ready for immediate installation.
We hold ISO 9001:2015 and NSF certifications, which means our quality system is audited and traceable. For regulated work, that documentation travels with your order.
Material Compatibility
C-Mac assembles the same materials we manufacture, so we understand how each one behaves under contamination-sensitive conditions. Common choices include:
- Alumina: Up to 99.8% pure, prized for hardness, electrical insulation, and chemical resistance
- Zirconia: High strength and fracture toughness, suited to medical and wear applications
- Silicon nitride: Strong at high temperatures with excellent thermal shock resistance
- Tungsten carbide: Extreme hardness for demanding wear surfaces
Mitigating Outgassing and Contamination in Vacuum Systems
High-vacuum environments present severe operational risks. Under deep vacuum, organic residues and uncleaned surfaces outgas, rapidly contaminating process chambers and ruining high-purity production runs.
To protect vacuum integrity, C-Mac enforces a two-step assembly standard:
- Pre-Assembly Surface Decontamination: Cleaning and inspecting each ceramic substrate prior to joining to eliminate outgassing agents.
- Controlled Environment Assembly: Executing the entire build within cleanrooms to prevent re-contamination before final seal.
The result is a sub-assembly that holds up in vacuum and high-purity settings. You can review our full range on our materials page, or see how these parts perform in medical and electronics applications.
