ProductsIC Test Sockets

Supporting Your Testing Needs with Flexible Customization
After semiconductor chips are diced from the wafer, they are packaged into various formats such as BGA, QFP, and others.
IC sockets are vital to ensuring the quality of these packaged devices through electrical testing, securely holding the chip in place with accurate probe pins.

The Structure of IC Sockets
At Seiken, we offer expertly designed IC sockets that are tailored to the specific requirements of your package. From layout to selecting the best contact probes, we customize every aspect based on your device’s shape, size, electrode design, materials, and surface treatments. Choose from a range of socket types to best suit your application:

Latch Type
A standard design perfect for multiple device testing, providing even pressure distribution with a convenient lid mechanism.

Clamshell Type
A hinged design that opens and closes easily, minimizing effort during repeated testing cycles.

Bottle Cap Type
Features an adjustable dial screw for fine control over contact pressure—ideal for high-pin-count devices that require strong contact force.
