Design, develop, and maintain printed circuit board assemblies and firmware for microcontroller based PCBAs used in high voltage electron beam acceleration equipment.• Completed development of Overcurrent Protection PCBA designed by colleague Peter Fisher. - This PCBA is used with the Extractor Controller PCBA (e-beam grid SMPS) to protect the switching MOSFET of the SMPS from damage and ultimate failure as a result of e-beam grid-to-filament shorts. • Modified PCB layout and firmware for multichannel Radiation Monitor PCBA to:- Eliminate spurious cross-channel faults and alarms- Replace existing reset pushbutton switch with a more rugged and reliable part- Eliminate accumulated reset switch dwell count and improve reset switch response

Westborough, Ma, Us

Temporary contract positionMaintained and developed hardware and software for Large Format battery module (Swing Tempo) and block (Swing Key) production testing. Supported design engineering on product integration issues. Supported manufacturing on electrical test issues.• Developed test procedure and conducted testing for Final Quality Checks of battery stacks (modules) used as part of rechargeable energy storage systems (RESS) developed for Beijing Electric Vehicle Company.• Refactored test application written in C# for battery cycling test stand used for Final Quality Checks to allow setting of operating parameters via external configuration files in XML format. This eliminated creating copies of the test program with internal variables set to new operating parameters for each new product tested.• Rebuilt battery cycling test stand into closed rack enclosure with improved layout and fixturing.
