Sr.Test Eng. / Team Leader
-
1988 - 1995
· Responsible for the quoting, designing, buying, and development (build and debug) of up to $5,000,000 annually of custom, high volume test equipment. · Supervised a design team (6 Test Engineers, 2 Technicians) in the development a universal (CORE) Air-Bag controller (safety critical) test system. · Responsible for the development and support staff of manufacturing testing (In-Circuit, Environmental Stress Screening, Functional Test, and Quality Audit) of 2 million air-bag controller modules per year. Test systems capable delivering <200 p.p.m. quality levels. · Conceptualized and designed (analog and digital) the CORE system capable of testing product for 10 different customer designs and over 40 different platforms. Reduced tester cost by 50%. · Structured, supervised, and co-developed universal testing software (25,000 lines) for the CORE system. .EXE file controlled by an external text-based command file. · Coordinated and interfaced with an outside vendor in the construction of 50+ CORE systems. · Developed production testing specifications, test coverage matrices, and testing process flow. · Designed tester interface and custom control boards for PC/AT (ISA) and industrial (STD) computer architectures. · Participated in many Concurrent Engineering teams to improve design for manufacturability (testability). Improvements resulted in 60% reduction in test time and 25% increase in test coverage. · Designed and developed hardware and software for testing various automotive controller units, high reliability switch-mode power supplies (IBM) and 14 channel network controllers (IBM AS-400). · Specified and contracted, with an outside vendor, the development of a 1 MegaWord/second, DSP controlled, 13 channel (differential) input, 2 channel output Analog Data Acquisition card. · Worked directly with Caterpillar Sensors and Diesel Engine Management Group on PEEC, 3176, & ADEMII on new testing strategies, DFM/DFT improvements.
