Industry Leader in Taiwan: Rung-Hua —— The Pioneer of Japan-Grade Anti-Static Grip Rings / Wafer Expander Rings / Wafer Hoop Rings
Founded in 1999, Rung-Hua is a premier leader in professional anti-static engineering plastic injection molding. Since 2002, we have leveraged decades of technical expertise to focus on the R&D and production of "Anti-Static Grip Rings." With exceptional stability and precision specifications, we have become the designated core supplier for global semiconductor giants, Tier-1 OSAT (Outsourced Semiconductor Assembly and Test) facilities, and LED leaders.
1. Global Innovation: Japan-Grade "Permanent" Anti-Static Technology
Integrating precision manufacturing standards from Japan, we developed a patented permanent conductive technology. Unlike standard surface coatings, our anti-static properties are embedded within the material core. This ensures protection that never degrades over time, through washing, or via friction—completely eliminating the risk of wafer damage caused by electrostatic failure during the manufacturing process.
2. Data-Driven Excellence: World-Class Measurement Systems
Every batch of Grip Rings undergoes rigorous testing with precision instruments to ensure quality exceeds the strictest international standards:
Redefining Anti-Static Standards: Equipped with the Prostat PRS-812B professional resistance meter and patented pin-point probes, we ensure "Zero Static Blind Spots." With resistance precisely locked between 10³ ~ 10¹¹ Ω, we provide the most reliable quality commitment for your products.
High-Precision Dimensional Control: Utilizing automated 2.5D/3D vision measurement systems, we strictly maintain product tolerances within ±0.01mm.
Mechanical Stress Validation: Our universal material testing machines simulate expansion stress during processing, ensuring high rigidity, low warpage, and excellent fatigue resistance.
3. Market Leader: The Standard Choice for Industry Giants
As the largest supplier of anti-static Grip Rings in Taiwan, Rung-Hua utilizes high-end fiberglass materials from Owens Corning (USA). Our products have long passed the rigorous validations of domestic and international industry leaders and are fully compliant with RoHS and SVHC international regulations.
Our Commitment:
To manufacture the world's finest grip rings
Driven by the stable quality certified by global leading manufacturers and our industry-shaping technology, Rung-Hua Enterprise maintains a rigorous defect rate of less than 1 ppm (one in a million). With this ultimate standard of quality control, we steadfastly safeguard every single wafer-processing component throughout the precision manufacturing process.
