In our ISO-7 cleanroom, we manage the complete in-house process of producing and assembling critical submodules — from precision part fabrication, ultrasonic cleaning, and cleanroom assembly to final functional testing and vacuum packaging — all within the Tonasco Smart Factory.
✔️ All components are fabricated and cleaned in-house, then inspected under both bright light and black light before assembly.
✔️ Mechanical assembly is performed in a controlled cleanroom environment, where the cleanliness of both parts and tools is strictly maintained.
✔️ After assembly, each unit undergoes a gravity drop test: mounted on a jig, tilted at a controlled angle, and verified to slide smoothly under its own weight. Any sticking or hesitation indicates misalignment or contamination.
✔️ A final post-assembly cleanliness check with white and black light confirms the product is ready for delivery.
⚙️ Why It Matters
Our customers operate in clean environments, often under ultra-high vacuum conditions, where even microscopic dust or chemical contamination can impact performance or damage equipment. For that reason, cleanroom assembly and verification are non-negotiable. Some of the common applications include
• Front-end semiconductor equipment
• High-accuracy metrology systems
• Optical systems
By combining complex precision machining, in-house cleaning, and ISO-7 cleanroom assembly. Tonasco offers a complete solution for customers looking to outsource submodules with confidence in quality and reliability.
