Professional Experience

GEOTEST - MARVIN TEST SYSTEMS, Irvine, CA 2006 - 2009

HARDWARE TEST DEVELOPMENT ENGINEER

. Work in fast-paced environment designing, integrating, and documenting

Test Program Sets(TPS) for commercial and military electronics and

test system development tasks. Develop, integrate and bring up the

Missile Launcher System to test the launchers of the F14, F16, and

F18. System trouble-shooting, debugging, and check out. Customer

support on failure after product shipped. Design activities include

hardware (Interface Test Adapters - ITAs), software, design and

integration. Use Altium 6, OrCAD, ATEasy/LabView, Logic Analyzer,

Digital Oscilloscope.

WESTERN DIGITAL TECHNOLOGIES, Lake Forest, CA 2000 - 2006

PRINCIPAL FAILURE ANALYSIS ENGINEER

. Responsible for Failure Analysis of 3.5" and 2.5" Hard Disk Drives.

Performs failure analysis for drives that failed during product

development, manufacturing process, reliability tests, or customer

returned drives including qualification failures, line failures and

field failures. Failure analysis includes determining root-cause of

hard drive failure at H.D.A (Head and Disk Assembly) including the

read/write channel. In addition to performing analysis to root cause

of failure to ensure corrective actions are implemented on particular

failures to prevent them from occurring on future products and/or to

make sure we can prevent the same type of failure from continuing to

ship from our factory process via screens/additional tests.

SEAGATE TECHNOLOGY, Inc., Santa Maria, CA 1999 - 2000

DEVELOPMENT/ELECTRONICS ENGINEER

debug in support of test system for tape heads. Used ORCAD for

schematics capture, LeCroy oscilloscope, Spectrum Analyzer as well as

Network Analyzer, to work. Used Visual Basic and C for programming.

Achieved the 350 MHz Clock Generator board.

3. Developed the Module Buffer Board (MBB) for the Burn In Tester.

4. Designed and prototyped the Clock Head Preamplifier Test Box.

Served as the Lead Engineer in Test Equipment Group (six technicians) to

design test fixtures for the DC100 Media Certifier, including the Main

Amplifier, Preamplifier, Surface Analyzer, FIFO, Mechanical Control, and

Glide Amplifier boards.

5. Generated the project schedule and completed tasks on time.

< Qualified the Disk Drive test process using Statistical Process

Control and Gauge Capability analysis.

Start up company that develop the hard disk for computer industry:

. Responsible for electrical design, schematic entry, prototype wire

wrap, test, debug, and documentation the Read/Write Spin Stand. This

test equipment was used to do read/write on media thru read/write

channel.

. Other responsibility was to design Contact Start-Stop Tester which was

used to do the wear test on media surface; to design the Friction

Tester which was used to measure the friction force between recording

head and media.

. Performed experiments on hard disk media of the company product and

reversed engineering on competitors hard disk media during the media

development.
