Innovative Solutions for
Semiconductor Testing

Advanced test services and engineering solutions for manufacturers of analog and mixed-signal semiconductor components — maximizing yield and quality, not cost per hour.

WHAT WE DO

A complete arc of
semiconductor testing.

From wafer sort to final functional test, USEA delivers turnkey engineering that scales seamlessly from a few parts to millions per month — all visible in real time through the cloud.

Turnkey Solutions

From wafer sort through assembly, parametric and final functional testing — hot, cold, and ambient.

Wafer Test (Sort)

High-throughput probing of bumped or bare die, before or after saw, across multiple temperatures.

Specialty Testing

Highly parallel UIL/UIS, RG/CG, QG and DC testing on single insertions via the QM1000™.

Reliability Testing

From wafer sort through assembly, parametric and final functional testing — hot, cold, and ambient.

Test Development

From wafer sort through assembly, parametric and final functional testing — hot, cold, and ambient.

Board Repair

USEA Engineer are expert in the repair, fabricate and upgrade automated test equipment (ATE) boards.

our heritage

First to offer contract analog test development.. Still leading

Founded in 1979, USEA began contract assembly in 1985, expanded to contract testing in 1990, and in 1996 became the first company to offer contract analog test development. Today we remain focused on advanced test services for analog and mixed-signal manufacturers worldwide.

Engineered in-house

The instruments behind
the yield.

Proprietary testers, diagnostic tools and cloud software — designed and built by USEA engineers to expand the capabilities of industry-standard platforms.

Tester

QM1000™ Quad-SiteTester

The QM1000™ quad-site instrument performs both DC and specialty AC tests on a single insertion, reducing device handling and eliminating the need for multiple external instruments — delivering up to 4× improvement in test throughput and yield.
