Reliability Qualification

Reliability qualification demonstrates the fitness of a product for use in the field and helps our clients better understand the fundamental wear-out mechanisms, detect design marginality combined with parameter drift and determine failure rates due to latent manufacturing defects. EAG provides stress based reliability qualification and knowledge based reliability qualification methodologies based on industry standards. EAG has optimized our services so no matter if you need maximum value and fast response or complete outsourced services, EAG’s experienced Reliability Engineers can create qualification plans and perform testing to meet your requirements with strict adherence to applicable JEDEC and MIL-STD specifications.

Stress Based Testing

Stress based qualification methodology provides a broad approach to identifying failure mechanisms and is a powerful tool to help engineers identify devices that may fail under normal use conditions. Thermal cycling, bias/humidity stress testing are conditions which many products experience and test conditions are designed to accelerate failures compared to field conditions.

Knowledge Based Testing

Knowledge based qualification methodology is based upon detecting and understanding specific failure mechanisms. When a failure mechanism is known, accelerated testing can be designed to detect those failures prior to placing a product in the field.
