About GD4

GD4 Test Services, Inc. (“GD4”) was formed in 2007 by a group of engineers.  The original concept of the organization was to provide electrical/functional testing on a project level with various semiconductor companies in the Austin, Texas area.

From its inception, GD4 began to recognize the requests and needs for component level testing from a variety of companies and markets on a small-scale per lot basis.

From these humble beginnings, GD4 Test Services, Inc. has progressed into a streamlined and versatile test lab with three strategically placed U.S. locations: Austin, Texas; Largo, Florida and Yaphank (Long Island,) New York.

We offer a robust list of capabilities geared toward the concept of quick, efficient component screening for authenticity, functionality, counterfeit mitigation, along with associated back-end services.
