PROFESSIONAL EXPERIENCE:

Confidential, San Jose, CA

Test Technician

Responsibilities:

• Perform bench testing for Confidential ’s Atheros chipset. Testing is done for chips and boards. Chips are used for routers & cellular wireless mobile devices.
• Main task is to perform DPPM (Defective Parts Per Million) testing on chips and boards. DPPM testing for chips is testing for Bluetooth & FM. Audio is part of FM testing. Use Confidential ’s internal QSPR program for chip testing. QSPR program is used to run, execute testing then to evaluate the overall performance of chip testing. Testing is done using an Agilent DC Power supply E3640A, Bluetooth RF switch 10-Y7006, Rhode & Schwarz CBT- Bluetooth Tester, Rhode & Schwarz SMB 100A- Signal Generators (3 units) (range of 9 KHz….1.1 GHz), Audio Precision sys-2722 - 192k, & Audio Precision programmable Serial Interface Adapter PSIA-2722.
• DPPM testing for boards is done using Confidential ’s Cherokee utility board along with an MTP debug board. Use Confidential ’s internal QSPR program to perform testing. Testing is done using a LitePoint IQxel.
• Perform PMIC (Power Management Integrated Circuit) testing on boards and chips. Testing is done under extreme conditions such as very low and very high temperatures. Low and high temperature settings vary depending on the test. Testing is also performed under different voltage and current settings. Voltage and current settings can start from normal then can go very high or very low depending on the test script and can also fluctuate back and forth during the execution of the test.
