Configured PLC programs for swift and more streamlined performance. Develop methods of calibration that greatly reduce inaccuracy and calibration times. Made electrical and mechanical design changes to improve system performance, reduce downtime and ease assembly efforts. Studied and analyzed build variables and worked directly with customers to provide constant improvements of our products. Developed new build process that increase quality, reduce build times and remove variables that cause inconsistency in performance. Perform software testing to better the G.U.I. Worked closely with customers to meet their individual needs. Performed service, repair, training and installations of the SLA machines in several facilities across U.S.

Electrical Calibration Tech

6/2008-10/2011 Woodward HRT, Valencia, CA

Calibrated and repaired oscilloscopes, power supplies, thermocouples, DVM’s, PH indicators, environmental chambers, high pressure (15000psi) hydraulic test benches and any other electrical devices for an aerospace manufacturing facilities. Used FAA and NASA calibration procedures along with electrical schematics, oscilloscopes, function generators, power supplies, highly accurate DVM’s and other electrical devices to verify the systems and units operated within their tolerances. Custom fabricated test circuits and cables needed during calibrations. Troubleshoot down to circuit board level

Automation Systems Tech

3/2004 – 5/2008 Optical Systems Corp, Valencia, CA

Assembled, tested and qualified high accuracy automated machinery for the semiconductor industries. Performed mechanical, optical, laser, and collimator alignments on systems which have a resolution of 5 nanometers and/or 1 arc second. Assembled optical devices that require precise alignments such as collimators, prisms and microscopes. Assisted in the design changes of both electrical and mechanical components, as well as assisted software engineers to better the G.U.I. in final products. Setup motion control systems that included: liner and rotary servomotors, stepper motors, I/O, pneumatics, and most closed loop systems. Tuned closed loop motion control systems to be stable within +/- 5 nanometers. Built new systems from electrical and mechanical schematics and made them operate to the specifications set by the customers. Worked directly with the customers to meet their needs, included traveling both domestic and foreign for service calls, tending meetings to represent the company, training employees how to run and repair systems, and continuous improvements with customers’ feedback.

Automation Tech

4/2001 - 10/2003 Prodosyst Automation, Santee, CA

Assembled and tested automation systems for the medical manufacturing industry using electrical and mechanical drawings, performed service calls and installations. Performed prototype machining using a lathe, mill, drill press, band saw and other shop tools.

SKILLS/OBJECTIVES
