Industrial Applications

1. Semiconductor Wafer Fabrication Control

Utilizing the CK3M-CPU121 to control extremely precise wafer positioning and lithography deposition.

Problem Solved

In nanoscale semiconductor fabrication, generic logic controllers lack the microsecond-level determinism required. This controller's 25μs servo cycle and PMAC heritage eliminate synchronization latency, preventing fatal lithographic alignment defects on the nanometer scale.

2. High-Precision CNC Machining Centers

Integrating the CPU into complex multi-axis milling or turning machinery utilizing native G-Code capabilities.

Problem Solved

Traditional setups require separate G-Code interpreters and discrete motion cards. The CK3M-CPU121 runs G-Code natively and dynamically coordinates up to 8 axes over EtherCAT, reducing hardware footprint by 66% while improving servo precision during intricate tooling paths.

3. Automated Optical Inspection (AOI) Systems

Deploying the unit in PCB or flat-panel display inspection machines, synchronizing ultra-fast gantry movements with camera triggers.

Problem Solved

Vision inspection at rapid line speeds often suffers from image blur due to mismatched axis positions and camera strobes. The CPU's dual-core 1.0GHz processor and EtherCAT deterministic network ensure exact spatial coordination, triggering cameras exactly on position coordinates with zero variance.
