Optional Magnets for the WLA5000

For use on ISI's full line of WLA5000 Wafer Analyzers, we offer a comprehensive option list of user-interchangeable Magnet assemblies.

ISI recognizes that there is no "one-size-fits-all" solution for electromagnet designs, and has carefully considered solutions for specific end user applications.  Whether you require high field, large uniform zone, directional control, extremely low remanence, or ultra high-speed, one of our portfolio of over 15 unique magnet designs will surely meet your needs.

Our Electromagnets are maintenance-free and factory calibrated, requiring little to no recalibration by the user.  Our Tooling and Probecards are designed to position the DUT at the specific uniform zone target of each magnet, allowing trouble- and calibration-free operation by the end user.

All of our Magnets are air-cooled, rather than water or other contaminating sources, and utilize our full complement of safety and protection features including overcurrent, resistance, and overheat monitors, making our Magnets suitable for operation in all manufacturing environments.

For use on ISI's full line of WLA5000 Wafer Analyzers, we have developed 5 unique user-interchangeable Wafer Magnet assemblies, tailored for specific applications:

  • 3K Oe Inplane QuadPole Magnet
    Ideal for Inplane field testing with full rotational control and low remanence and high Z field uniformity.

  • 5K Oe Perpendicular Magnet
    Ideal for Perpendicular field testing with low remanence and high Z field uniformity.

  • 1T (10K Oe) Perpendicular Magnet
    Ideal for Perpendicular field testing at high fields with low remanence under closed-loop control, and quickly interchangeable with 1.5T pole configuration.

  • 1.5T (15K Oe) Perpendicular Magnet
    Ideal for Perpendicular field testing at high fields with low remanence under closed-loop control, and quickly interchangeable with 1T pole configuration.

  • 3-Axis X/Y/Z Magnet
    Ideal for multi-axis testing with full rotational control and low remanence.

All of our Electromagnets are proprietary designs by ISI, specifically designed for use with our software, controllers, power supplies, mechanics, and probecard assembly.  As fully integrated systems the highest in performance will be realized by the customer.
