Cohu offers a big variety of magnetic test solutions applying magnetic field in all three dimensions. Depending on the requirements we can integrate coils with and without magnetic core, single- or Helmholtz coils, as well as permanent magnets, static and rotating.

The Cohu solutions ensure excellent magnetic field homogeneity and high magnetic field strengths up to 100 mT. Out of according magnetic simulations we can recommend the ideal combination of the available magnetic field sources.

With use of our high efficient handler portfolio we can provide the required position and angle accuracy to ensure highest test repeatability and yield. Our batch handling solutions offer optimized throughput combined with best in class precision for Test-in-Strip or InCarrier.
