A high-speed automatic testing system for inductors that automates the impulse test and significantly reduces process time.
During production inspections and measurements, winding components undergo tests to ensure the product's pressure resistance. For example, insulation failures in coils can be caused by rare shorts that occur in the usual operating environment, leading to design flaws, molding processing defects, and deterioration of insulating materials. Therefore, it is necessary to conduct rare short tests. If you are using slow measurement equipment, you will not be able to meet the increasing demands from customers. To address this, Chroma has utilized its accumulated expertise as a measurement instrument manufacturer to develop a high-speed rare short automatic testing system. By combining Chroma's strengths in measurement instruments, we provide a fast and accurate automation solution.
