Professional profile
Designed and developed 1.6 kV high-voltage test racks with interface boxes, RC discharge circuits, supply instruments to test high voltage PCBAs. Supported assembly, testing, debugging, validation, and factory deployment of 4 high-voltage testers and 2 calibration testers, while managing direct client interactions and cross-functional coordination.. Prepared BOMs, quotations/proposals, test specifications, validation documents, wiring diagrams, assembly drawings, test procedures, and user manuals; trained junior engineers and supported ISO documentation.
Designed and deployed electro-mechanical PCBA testing fixtures for solar energy products including microinverters, control boards, communication boards, and BMUs.. Developed a yield-report automation workflow that reduced a manual ~1.5-hour daily process to ~10 minutes, an approximately 89% reduction in processing time.. Performed factory bring-up, production testing, and troubleshooting to maintain a 97% FPY in factory production floor. Delivered 15 test change kits and another 7 change kits of different variant within committed timelines without customer escalations; supported 10+ sub projects.
Acquired practical knowledge in battery management systems (BMS), emphasizing cell balancing, protection circuits, and thermal management for electric vehicles.. Designed protection and indication circuits using opto-couplers and diodes, enhancing circuit functionality.
Recovering 10 damaged servo boards, 7 cell emulation boards through troubleshooting and rework.. Developed PyQt5-based GUI applications for test head motion control.. Performed functional and system-level PCBA testing and hardware debugging using multimeters, electronic loads, power supplies, DAQ, and power measurement equipment.
