Summary: Four years of experience designing and working with large high precision industrial ink-jet (IIJ) printing systems used in the production of flat-panel displays. Recently responsible for the development, from concept to completion, of a high precision, high performance, Generation 8 size (5m x 6m x 25 mm XYZ travel) XYZ stage that was in spec, on schedule, and within budget.
Professional Experience: Litrex Corporation Pleasanton, CA Motion Systems Engineer 7/04-Current Overview Responsible for the development, build, configuration, tuning, calibration, and support of high axes-count, micron-level-precision motion systems Quickly moved from entry-level position to overall motion system architect with management-level responsibilities Consistently recognized as highest tier contributor in annual performance evaluations
Generation 8 Motion System Technical Lead 1/07-Present Developed, from concept to completion, a high precision, high performance, Gen 8 stage Generated stage specifications and conceptual layout based on printing strategies, error budget analysis, and TACT-time requirements Used FEA (Mechanica) and Matlab simulations to size the machine’s structural elements to maximize machine accuracy and throughput Achieved demanding repeatability, velocity, acceleration, and step-and-settle specifications Devised the motion system architecture used to control all twenty-seven axes of motion; specified axes layout, control strategies, safety mechanisms, system stiffness requirements, controller components, amplifiers, encoders, and motors Directed development of motion controller firmware and created specifications for upper level software tools used to enhance the reliability of the motion system while simplifying debugging and service of the motion system Configured, tuned, and programmed the system’s motion controllers
Generation 5.5 System Technical Program Manager 6/06-12/06 Managed an international interdisciplinary team in the development of a high accuracy version of a G5.5 size IIJ printer Synchronized efforts between team members and consultants in Texas, California, and Japan Responsible for the specification and design of the G5.5 stage Delivered an extensive design complete documentation package on time
Generation 5.5 Stage Lead Engineer 1/06-6/06 Collaborated with stage vendor to modify and improve an existing design Performed FEA analysis on stage structure to improve stage stiffness and reduce relative (X vs. Y) motion issues in the original design Teamed up with a motor vendor to develop a custom arc-shaped linear motor to enable direct-drive of a high precision rotary axis
Motion Systems Engineer 7/04-1/06 Worked with a stage vendor to specify and integrate a 4-axis motion subsystem into an existing main stage design Selected and packaged motion control components and support electronics Created interconnect diagrams in Orcad. Designed and built all cable assemblies Tuned motion controller and developed motion controller firmware based on specifications from upper-level software team Led interdisciplinary team during product installation in South Korea Performed laser interferometer measurements and implemented compensation algorithms
Other accomplishments Advanced level of proficiency with Delta Tau motion controllers Experience with customers in the FPD industry such as: AUO, Samsung, DNP, LPL Acted as key interface to Japanese parent and sister companies; led extensive concept discussions with Litrex’s parent and sister companies during initial product development; made presentations to parent company’s board of directors Contributed to new customer design proposals and feasibility studies; generated system concept drawings; analyzed head array layouts and printing strategies Actively participated in executive staff operations reviews Trained field service personnel and new engineering staff Participated in off-site management training Interviewed new hires and assisted in the performance review of fellow employees Received additional training in Pro/Engineer, Mechanism, and Mechanica Skilled with both Agilent and Renishaw laser metrology systems. Well versed with National Instruments hardware and software. Developed custom applications for engineering and field service use Experience with the specification and use of products from vendors such as: Delta Tau, Renishaw, Heidenhain, Tecnotion, Glentek, Parker Trilogy, Baldor, HSI, Kollmorgen, Copley Controls, Logosol, Geckodrive, Microe, US Digital, Dover, Neat, Danaher Motion, Bell-Everman, Alio, Nanomotion, Etel, Airpot, NSK, New Way, Ibex, Primatics, Yaskawa, Tamagawa-Seiki, IMS, Trinamic, Applimotion, Sigma-Technos
Education: M.S., Mechanical Engineering, California Polytechnic State University, San Luis Obispo GPA 3.3 B.S., Mechanical Engineering, California Polytechnic State University, San Luis Obispo GPA 3.0
Masters Thesis: The implementation, modeling, and optimization of a LabVIEW-based series hybrid-electric vehicle control system for Cal Poly’s Future Truck. Used National Instruments hardware and software to control a diesel engine’s RPM, to synchronize CAN, serial, and Ethernet communications with the various power system components, and to automate the overall charging system’s operation.
