SUMMARY:

Degreed Mechanical Engineer from the University of Colorado in Boulder. Thirty - five years of experience in mechanical engineering design of high precision mass produced components and subassemblies, primarily in the data storage/consumer electronics industry. Extensive experience with the mechanical development process, from prototype stages through the testing and qualification of components and assemblies utilizing DFM/DFA/DFC and LEAN/Six Sigma Black Belt principles to deliver the design into high volume mass production. Completely conversant in the design of components utilizing metal die casting, plastic injection molding, CNC machining, sheet metal stamping/forming, fine blanking, Flexible Printed Circuits, and die cutting of seals/labels. Experience with airflow and filtration in hard disk drives. Highly proficient in CAD solid modeling and preparing working drawings. Highly proficient in use of geometric tolerancing and dimensioning, as well as statistical tolerance analysis of multi-component assemblies.

Confidential, Lafayette, CO

Responsibilities:

• I represented Confidential Inc. by performing intellectual property searches for Confidential ’s law firm to debunk claims in a patent infringement lawsuit brought about by Seagate Technology.

Confidential, Longmont, CO

Sr. Staff Mechanical Engineer

Responsibilities:

• Mechanical Test & Instrumentation group performing non-op shock testing at component level and drive level. Performed fragility testing on micro actuated recording head, resulting in timely integration of micro-actuated head into the Grizzly Program.
• Assigned to NPI group which transitioned products into the Maxtor Singapore factories.
• Tasks were to perform root cause failure analysis on HDDs produced on the pilot line.
• Debugged no latch failures diagnostic, resulting in a 5% yield gain and timely transition into production.
• Performed advanced failure analysis techniques, improving pilot line and factory yields, which resulted in entry into high volume mass production.

Confidential, Longmont, CO

Responsibilities:

• Completed intensive 4-week statistical methods training program entitled Design for Six-Sigma Black Belt.
• I led a six-sigma project to reduce FAI time by developing a 3D laser scanning inspection system. in Product Development group performing clean sheet redesign of Zip 3.5” removable media mechanical platform for a cost reduction effort. Assigned to HSA/VCM redesign, which resulted in a significant cost savings for the Zip program.
• Awarded patents for “Head Retract Assembly for Disk Drive” and “Commonly Actuated Head Retract Assembly and Cartridge Transport Assembly for Disk Drive”.

Confidential, Longmont, CO

Sr. Staff Mechanical Engineer

Responsibilities:

• Developing a non-contact actuator positioning device for the servo track writer.
• Generated patent disclosure form for “Method of Producing Reflective Groove on Target”.
• Sr. Mechanical Manager and primary mechanical architect for the Devo program, a 1-inch tall 5.25” HDD. Led Maxtor Mechanical Design Department ISO-9001 Implementation Team, resulting in the generation of the Product Life Cycle Document defining how HDD products are developed and brought into production.
• Mechanical Product Development Lead Engineer and mechanical architect for the Aruba ½ inch tall 2.5” HDD program. Assigned to Maxtor Patent Review Committee, which ascertained the worthiness of new patent disclosures for Maxtor.
• Mechanical Product Development Lead Engineer and mechanical architect for the Baja 10 mm 1.8” HDD program. Conceived wire clip disk clamp retainer design, which was later patented (U.S. Patent # 6,624,968).
• Mechanical Product Development Lead Engineer: Assigned to Racer/Runner 1.8” program to close remaining open design issues, so that it could be brought into production. Led a task force team that made a liquid metal rotary shock sensor manufacturable, thereby allowing the 1.8” product to ramp into mass production.
• Spin motor Product Development Engineer on the Apache3 and Papoose HDD concurrent programs. Pioneered bond in place spin motor design that became industry-wide standard, resulting in significant cost savings, and performance improvements in precision alignment, contamination control, and structural stiffness.
