ESD and LU (EOS) SERVICES

Liberty Test laboratory provides superior ESD and Latch-Up (EOS) engineering services for the semiconductor industry. With over 22 years of experience in Engineering Evaluations and Production Qualifications, we take on the complex debugging and find solutions quickly that result in faster “to market” qualifications.

Our lab is equipped with latest, fully upgraded ESD/LU test systems that have exceptional high speed performance and are the ideal solution for providing outstanding test services for product and R&D engineering, IC structure designing and QA programs. We have a large in-house library of universal and customized load boards that are sure to accommodate most packages. Among independent laboratories, we have one of the largest arsenals of ESD/LU testers in one location. With capacity not being an issue, we are focused on customer driven goals and deadlines. We are committed to meeting or exceeding our customers’ expectations through outstanding services.

Liberty Test is an ‘Accredited Laboratory’ in accordance with International Standard ISO/IEC 17025:2005, awarded certification by A2LA (American Association of Laboratory Accreditation). All testing performed in compliance with JEDEC, ESDA and AEC (automotive) industry specifications.
