Precision Fine-Pitch Twisting for Resistance to External Noise

5G, AI, autonomous driving, IoT, EVs, and the metaverse are driving rapid growth in semiconductor demand. At the same time, advances in semiconductor performance and miniaturization are increasing the requirements for positioning accuracy in semiconductor manufacturing equipment. In particular, even minimal noise on low-current, high-speed transmission lines used for motion control and sensing can adversely affect equipment performance and processing accuracy, making stable signal transmission a critical issue.

Generally, noise countermeasures involve strengthening shielding. However, this approach can increase the cable's outer diameter and rigidity, leading to greater loads on moving parts and increased equipment vibration, which can in turn generate noise and reduce positioning accuracy. Furthermore, as equipment becomes smaller and more densely packed, the demand for space-saving designs and greater flexibility continues to grow.

At Junkosha, we have developed a proprietary technology for manufacturing twisted-pair signal lines that uniformly controls strand tension and length, helping to reduce timing deviations and variations in noise effects during signal transmission. This technology supports enhanced noise immunity while maintaining cable flexibility and ease of handling, contributing to high-precision positioning control and stable signal transmission.
