Boulogne-Billancourt, Île-de-France, FR

• Product Reliability and Failure Analysis supporting development in Texas and China, manufacturing in Mexico and China and customers globally. Interfaced with customers in reviewing applications where power products.
• Performed RCA on 35W AC/DC Power Supply and concluded that the combination PFC/LLC controller contained an intrinsic flaw which caused switching MOSFET failures in THB. Identified film input filter capacitor.
• Worked with router customer to resolve a POL module application issue, which resulted in intermittent operation upon start-up. Provided consultation to enhance customer’s analog measurement techniques.
• Mentored team reviewing GaN MOSFET applications in DC/DC brick modules.

US

• Component and Product Reliability supporting Development in Texas, California, Switzerland and China and manufacturing in Mexico, China and Poland.
• Resolved repeated failures of 66W BMP DC/DC Converter in customer router deployed in Japan. Identified customer application susceptibility to atmospheric phenomena and recommended grounding and protection improvement.
• Resolved catastrophic failure of 1MW UPS caused by 1200V IGBT shorting due to cosmic radiation susceptibility. Recommended replacement of IGBTs with radiation hardened devices affecting over 50MW at various datacenters.
• Deployed Design for Reliability (DFR) process globally thereby standardizing across all divisions. This resulted in product teams identifying reliability risks earlier in the development cycle and developing action.
• Collaborated with Sourcing to achieve an immediate $250K cost reduction for high current DC circuit breakers by negotiating with Canadian supplier and recommending cost reduction through standardization of contact.

• Component Engineering, Reliability and Supplier Quality supporting product Development and Sourcing in Texas and China and manufacturing in Mexico and China. Led a group of Component Engineers responsible for.
• Integrated Lineage Power Sourcing Quality Management System and Technical Regulations Standards as well as Design for Reliability and NPI processes into GE Energy’s processes ensuring best-in-class processes.
• Defined a FRACAS system to integrate multiple development, customer quality and Design Archive of Mistakes databases into a single tool driven from the PLM system.
• Improved DFM process by incorporating strain gage analysis of critical MLCC placement on PCB’s.
• Led subcommittee responsible for updating IPC-9592B Derating Guidance and presented at APEC-2012
• Conducted a study and documented the DC Bias Aging phenomenon of MLCC’s which causes the capacitance of MLCC’s to reduce, over time, beyond the datasheet specifications. This resulted in resolving a customer issue.

Bengaluru, Karnataka, IN

• Component Engineering, Reliability and Supplier Quality supporting product Development and Sourcing in Texas, California, India, Mexico and China and manufacturing in Mexico and China.
