ProductsNon-Magnetic Probe Card

Enabling High-Precision Testing in Non-Magnetic Environments
Seiken’s non-magnetic probe cards are engineered from the ground up, backed by years of experience, very detail—from material selection and precision machining to surface treatment, PCB manufacturing, and assembly—is carefully managed within a fully integrated process. The result is a probe card that delivers consistently stable, high-precision inspections even in the most magnetically sensitive environments.
An optional socket kit further expands functionality, making these probe cards ideal for manual testing of packaged devices.
Ideal for testing components sensitive to magnetic fields—such as electronic compassesーour non-magnetic probe cards provide reliable solutions where uncompromised measurement accuracy is essential.
