Semiconductor | Precision Equipment Components

In both front-end semiconductor manufacturing (wafer fabrication) and back-end packaging and testing equipment, aluminum alloy components have become the mainstream choice due to their lightweight properties, excellent thermal conductivity, and superior machinability. However, semiconductor manufacturing environments demand extremely strict vacuum sealing performance and micron-level GD&T (Geometric Dimensioning & Tolerancing) accuracy.
By integrating high-quality die-casting processes with ultra-precision spindle machining technology, TRY Taiwan provides highly stable component solutions specifically designed for the semiconductor industry.

1. Solving the "Porosity and Vacuum" Challenges of Die-Cast Parts

Semiconductor equipment frequently operates in vacuum environments such as vacuum chambers. Conventional die-cast components often contain microscopic porosity, which may result in vacuum leakage.

• Vacuum Die Casting Technology: During the die-casting stage, we optimize mold flow analysis and apply vacuum-assisted casting technology to minimize gas entrapment.
• Precision Spindle Machining for Sealing Surfaces: During CNC machining, low-vibration spindle systems are used for precision milling to ensure that O-ring grooves and sealing surfaces achieve exceptional flatness, preventing micro leakage caused by machining marks.

2. Advanced Geometric Tolerances: Pursuing Zero-Error Assembly

Semiconductor robotic arms and wafer handling systems (EFEM) require extremely high repeat positioning accuracy. Any perpendicularity or parallelism deviation caused by spindle instability can amplify into system-level positioning errors.

• Spindle Runout Control: We strictly control spindle runout within micron-level tolerances, ensuring that hole positions and geometric centers fully comply with engineering drawings.
• High CPK Validation Standards: For semiconductor components, our critical dimension CPK target is maintained above 1.67. Through data-driven process control, we ensure 100% interchangeability between batches during assembly.

3. Extreme Surface Requirements: Roughness and Cleanliness

Semiconductor components often require hard anodizing or specialized chemical surface treatments. The surface roughness (Ra value) generated during machining directly affects coating uniformity.

• Minimizing Subsurface Damage: High-precision ceramic-bearing spindle systems provide stable cutting forces, reducing work hardening and microscopic cracking. This not only achieves ultra-smooth surfaces but also supports ultrasonic cleaning and cleanroom assembly standards.
• Thermal Conductivity and Static Dissipation: For testing fixture components, highly flat machined surfaces improve thermal transfer efficiency and provide stable grounding paths, preventing electrostatic buildup that could affect chip testing.

4. Tool Wear Management and Material Challenges

Semiconductor-grade aluminum alloys, especially high-silicon aluminum alloys, possess strong abrasive characteristics. If spindle rotation lacks stability, adhesive wear and galling (Festfressen) can rapidly occur at the cutting edge, negatively affecting machining quality.

• Efficient Cutting Strategies: By combining high-rigidity spindle systems with precise feed control, we effectively evacuate chips and reduce heat accumulation, ensuring stable quality consistency and competitive production costs in mass production.
