Electrical Test & Reliability Lab
A leading provider of qualification, design verification, reliability testing, and electrical testing services (including bare die, wafer, and package) for IDMs (Integrated Die Manufacturer) and OEMs (Original Equipment Manufacturer) in harsh environments such as military, aerospace, nuclear, automotive and medical, oil field industries.
Electrical & Reliability Testing
Electrical & Reliability Testing can be conducted at various stages of the manufacturing process, including the die, wafer, package, and module levels. Each of these stages has its own set of testing techniques and objectives based on the device datasheet and according to different standards such as MIL Std., JEDEC, AECQ, ESA Std, Nasa Std and specific customer requirements.
