To meet customer’s specification: Stability, Vout Ripple, Steady State (Continue/ Discontinue/ Burst Mode), Transient, Short Circuit, Thermal Test, Soft-Start, Efficiency, Start-up and Bode Plots needed to optimize by calculating and selecting proper Inductor (Current Rating, Temperature Rating, Size and Value), Output/ Input Capacitor (size and value), Frequency, Compensation Capacitor, Feed-Forward Capacitor, Soft-Start Capacitor.

Be able to perform and operate all necessary equipment in the Power Design Lab such as: Bode Plot Tool (Frequency Analyzer), Thermal Camera/ Thermal Meter, Digital Multi-Meter DMM, Pulse/Function Generator, Oscilloscope, Efficiency Meter (100 Raleay), SMC Solder, Computer (Fax, Printer, Excel, Microsoft Word, Power Point slides), Linear-Designed Simulation Software (LTC-SWITCHER), Linear-Designed Layout Software/Machine.

11/16/06-04/28/07: Associate Test Engineer (ATE), KLA-Tencor Corp.

In 100-class clean room, perform Software, mechanical and Optical setup, electrical test, laser alignment for an Automation Focus System (AFS), Bright Field (UV, VISIBLE, I-LINE & G-LINE) in Wafer Inspection Tooling Series 23XX (Escape and Explorer) using (IR) Autocollimator, and (IR) Visible Focus Collimator, High gauge, Micrometer, DMM, Oscilloscope, Optical Power Meter.

03/15/2006 - 07/10/2006: Electrical Designer, Acies Engineering.

Assisted Project Engineers and collaborated with Architects to prepare drawings using AutoCAD 2006, to design lighting and power plan, panel schedules and load calculation using Spreadsheet (MS Excel), single line design, and product specifications, to perform site surveys and title 24 calculations. Acknowledge of National Electrical Code 2005 (NEC2005).

08/15/2001-01/2006: Part-time Electrical Contractor, Self-Employed, Thomas’ Electrical & Design.

Contractor State License Board (CSLB): electrician License No. C10-870633

Acknowledge of National Electrical Code (NEC 2005) in residential, industrial and commercial electrical system. Prepared AutoCAD drawings and installed electrical wiring systems for home in Los Altos and Tracy. Installed receptacles, appliances, electrical wirings and troubleshot electricity while attending college.

1/23/2006-03/14/2006: Engineering Test Technician, Ultratech Inc.

In 100-class clean room, interfaced with engineers in pioneering a 1.5kW-LSA (Laser Spike Annealing): processed Demo Wafer, measured their resistivities and plot collected data. Inspected the processed wafers through Microscope to determine strength of Laser power and adjusted its power by writing recipe to be uploaded onto computer program. Carefully aligned Laser beam and handled 200-300mm wafers to avoid contamination.

02/00-08/01: Product Test Technician II, Electroglas Inc.

Tested and calibrated Laser-controlled XY Platen/Motors for Wafer Probing Equipment (200/300mm diameter) that used DRAM, Flash Memory, a system-on-a chip, and Hard Disk Drive (HDD). In profiling lab, loaded programs, saved data on EPROM memory and documented the tested platen/ motors.
