Built for the Most
Demanding Environments.
Semiconductor fabrication equipment demands tolerances, cleanliness, and material traceability that most contract manufacturers cannot meet. Trinity Wen Co., Ltd was built specifically for this environment.
Semiconductor OEM
The Precision Standard for Semiconductor Equipment Manufacturers
Semiconductor fabrication equipment operates at the intersection of extreme precision, chemical compatibility, and contamination control. Every component we manufacture for this sector is held to the same standard as the equipment it goes into — tight tolerances, full material traceability, and cleanroom-compatible finishing.
Application Areas
01
Wafer Handling Systems
Structural frames, end-effectors, and enclosure panels for automated wafer transport. Aluminium and stainless steel components machined to H7 bore tolerances with electropolished or anodised surfaces.
02
Process Chamber Components
Vacuum-compatible flanges, chamber liners, and mounting brackets. TIG-welded assemblies with full dimensional inspection and passivation to ASTM A967.
03
Cleanroom Equipment Enclosures
Sheet metal enclosures, doors, and panels for cleanroom-rated equipment. Powder-coated or anodised finishes with controlled outgassing properties.
04
Chemical Delivery Systems
Stainless steel 316L fabricated frames and brackets for chemical distribution modules. Electropolished internal surfaces and passivated external surfaces.
05
Metrology & Inspection Equipment
Precision-machined bases, stages, and structural members for metrology tools. Tight flatness and parallelism requirements met through 5-axis machining and CMM verification.
06
Thermal Management Components
Aluminium heat spreaders, cold plates, and cooling manifolds. Machined flow channels, pressure-tested assemblies, and anodised surfaces for thermal performance.
Other Industries We Can Serve
Industrial Automation
Structural frames, enclosures, and precision brackets for robotic and automated assembly systems. Our fabrication capabilities support the mechanical infrastructure of automation OEMs.
Medical Device Equipment
Cleanroom-compatible fabrication for medical device manufacturing equipment. Stainless steel and aluminium components with full material certification and traceability.
Precision Optics & Photonics
Vibration-sensitive optical equipment requires the same dimensional stability and surface quality as semiconductor tooling. We supply machined mounts, stages, and enclosures for photonics OEMs.
Defence & Aerospace
High-reliability fabrication for defence and aerospace sub-contractors. Aluminium, stainless steel, and titanium components with full documentation and first-article inspection.
Why OEM Engineers Specify Trinity Wen
Single-source accountability
All seven fabrication processes under one quality system. No inter-supplier handoffs, no tolerance stack-up from multiple vendors.
Material traceability
Full lot and heat traceability on all materials. Mill certificates and material test reports retained and available on request.
Cleanroom-compatible processes
TIG welding, electropolishing, passivation, and assembly operations are compatible with cleanroom delivery requirements.
Engineering-led review
Every RFQ is reviewed by our engineering team — not just a sales function. DFM feedback is provided as standard on complex assemblies.
Documentation package
Certificate of Conformance, dimensional inspection report, and material certs shipped with every order.
Rapid prototyping to production
The same processes and quality system serve both prototype and production volumes — no re-qualification required when scaling.
