Conductive slip rings are high-end, precision rotating core components for semiconductor equipment. Designed specifically for the semiconductor industry’s automated production environments, which demand high precision and reliability, they enable the stable transmission of power, encoder signals, and various sensitive signals during unrestricted 360° rotation. They feature a central through-hole to accommodate equipment drive shafts, process piping, and inspection cables. They can also integrate rotating joints for gas and liquid (capable of handling both positive and negative pressure), enabling the integrated transmission of electricity, signals, gas, and liquid. This makes them fully compatible with equipment across all stages of semiconductor manufacturing, including front-end processing, back-end packaging and testing, end-to-end inspection, and automation systems.

Core Application Scenarios for Conductive Slip Rings

Aligned with the entire production process of semiconductor wafer processing, chip packaging, and finished product testing, they are compatible with the rotating mechanisms of core equipment:

1. Front-end wafer manufacturing equipment: photoresist coating and developing machines, etchers, thin-film deposition equipment (PVD/CVD), and chemical mechanical polishing (CMP) machines. Used for rotating chucks, targets, and polishing heads, with through-holes for wafer carrier shafts and vacuum/process gas lines.

2. Back-end packaging and testing equipment: wafer dicing machines, die bonding machines, wire bonding machines, and encapsulation machines. Designed to accommodate rotating indexing tables and gripping mechanisms, with through-holes for suction tubing and testing/drive cables.

3. Full-process inspection and sorting equipment: wafer probe stations, chip visual inspection machines, and electrical performance testers, used with rotating worktables and gimbals to ensure high-fidelity signal transmission, with through-holes for lens focusing shafts and probe drive shafts.

4. Supporting automation equipment: Wafer AGV rotary lifting mechanisms, production line robots, and FOUP handling systems, compatible with rotary joints and loading stations, enabling compact, integrated transportation.
