Improved assembly yields 15% through characterization of thermal effects of eutectic solder voids on packaged GaN HEMTs. MRB review and disposition of non-conforming material. Provided technical support for die pick and inspection for Die Sales. Acted as SQE in communicating material non-conformances to suppliers. Completed 4 x AS9100 Quality System audits. Identified major and minor non-conformances, initiated and closed-out CAPAs to correct non-conformances.

Charlotte, North Carolina And Greensboro, North Carolina

Conducted accelerated life tests on GaN HEMT devices using DC stress test systems commissioned in 2008. Evaluated multi-temperature test parameters and sample failure rates to determine temperature-dependent acceleration factors and device time-to-failure distributions. Calculated MTTF using Arrhenius equation for reliability. Performed thermal and reliability characterizations across family of packaged GaN HEMT products, providing customers with critical information for product selection and operation.

Charlotte, North Carolina
