Quasys Test Socket Concept

Various ways to connect

The requirements in the semiconductor test are diverse, we at Quasys have made this to our base job to find suitable solutions for all conceivable situations. You give us your specifications and we select the optimal test solution for you from the portfolios of our partners.

Regardless of whether you need a test socket, a specific contactor solution or maybe just looking for the right contact pin, we have the products you need to push your project.

Because of the close cooperation with our partners, we have a variety of options in all areas of semiconductor testing. It doesn't matter whether you want to do a final test in production, process out analyzes or qualifications or do one of the many stress tests that a semiconductor has to pass. Whether you want to carry out Burn-In, HAST, HTOL, LTOL or your own highly demanding test concept, we will provide you with the right contacting solutions, because we not only offer standard solutions but also break new ground for you.

We are your reliable partner for reliable contacts.
