basic information

- Improvement of probe performance through new plating technology One of the challenges of the current spring test probes is the increase and variation in contact resistance over time. As a countermeasure, we are developing next-generation pure gold plating that achieves hardness comparable to Au-CO plating while offering superior electrical characteristics, aiming to improve contact resistance. - Development of spring probe pins using press pipes We aim to realize cost-effective spring test probes by manufacturing barrels through pressing. There are no gaps at the seams of the press, and it can accommodate small-diameter probe pins of φ0.4. *For more details, please refer to the PDF document or feel free to contact us.*
