DfR Engineer

Responsibilities:

• Successfully applied Reliability System Modeling to shorten design cycle time. One such model (DfRSoft) enabled the NPD team to select the best design option out of 6 in less than 5 days without testing. A BlockSim reliability model was created to assess system and component reliability incorporating functional requirements and application process steps (DFMEA).
• Trained engineers in Packers NPD group in numerous DfR classes using actual product examples.
• Collaborated with Sustaining Engineering to conduct Fault Tree Analysis (FTA) for a packer field failure to identify and confirm causes of failures using field data.
• Collaborated with Engineering to use DoE to optimize a shear screw for an assessor tool using Design Expert program verified by test data.
• Provided effective suggestions in multiple concurrent products in design brainstorming discussions, DFMEA plan creation, design reviews, and CLM documentation to reduce cost, improve product quality, and supplier relationship. The objectives were lower purchase cost, reduce delivery time, and improve product quality.

Confidential, Redwood Shores, California

Reliability Engineer

Responsibilities:

• Assisted HALT, HTOL, and Temperature Cycling testing for DVT test samples to identify reliability issues and solutions. Several failures were uncovered and reported back to Development for corrective actions.
• Researched and implemented neutron radiography (NDT) to identify nonmetallic defects inside micro-inverters. The result allowed the Development Engineers to improve the production process to eliminate defects.
• Created a DFMEA plan to help Product Development team to identify failure modes and generate test plans to resolve reliability issues.
• Completed an accelerated vibration test to identify possible stress fatigue failure root cause and solution to win a competitive contract replacing a competitor’s product offer to customer. The support bracket was redesigned to eliminate the potential field failure.

• Completed a Failure Analysis to identify root cause(corrosion reaction) of LED delamination failure.
• Managed the appropriate budgets, plans, and schedules concerning internal and external test resources to ensure meeting revenue goals.

Confidential, Newport Beach, California

Senior Reliability Engineer

Responsibilities:

• Shortened department response time (from several weeks to less than one week) in test request processing and design of qualifications plans. Streamlined test history research and plan creation enabling productivity despite a 50% global headcount reduction.
• Saved Conexant $200,000 through reliability testing on customer-supplied PCB with incorrect solder paste to verify the potential for reliability exposure.
• Designed and executed vibration and drop tests to identify product weaknesses(no wire strain relief) for a portable USB modem for laptop computers. The design defect was eliminated using the test result.

Confidential, San Jose, California

Component Engineer

Responsibilities:

• Developed innovative FPCA stiffener design in a collaborative effort, earning design disclosure . Design minimized the flexible printed circuit bias force to the actuator motion (U.S. Patent # 8213124 for a Flexible Printed Circuit Constraint).
• Optimized test and characterization criteria and processes that reduced test failure possibilities and enhanced testing infrastructure. Recommended, justified, and proved the purchase of x-ray equipment for flip chip solder joint testing and enhanced solder joint temperature cycling testing to meet JEDEC specifications.
• Implemented statistical sampling requirements to FPCA and suspension suppliers and provided ongoing statistical data establishing production design parameters.

Senior Member of Technical Staff

Responsibilities:

• Delivered two working water injection module (WIM) prototypes within three months to meet critical program checkpoint ensuring Alpha release. Earned corporate .
• Led the creation of the DFMEA for the PFC gas abatement device and identified high risk components for design changes.
• Performed the first-order thermal analysis to assess the temperature gradient inside the ceramic tube of the abatement device to determine the necessary design changes.

Senior Reliability Engineer
