Work History
Senior Test Development Engineer
Analog Devices Inc.
General Trias
07.2023 - Current
- Developed test hardware for ATE (Spea tester, DOT400S2) to ensure compliance with testing requirements.
- Develop Program in C++ to test the test parameters needed in SCM, target spec.
- Confirmed test program functionality through troubleshooting and debugging with test console, multimeter, and oscilloscope.
- Hardware design base on Test specification requirement given by designer and check Specification if proposed tester can measure the required specification.
- Qualified and supported customer data (CDM, HBM, Hast, uhast, bhast, Latch up) for early samples to facilitate product validation.
- Latest and on going development is acorn PMIC device, xCortes (Part of the team developing the customer silicon in ADI LK)
Test Developer
Rohm Electronics Philippines Inc.
Carmona
04.2010 - 06.2023
- Full Development Jobs – Test Plan, Program, Debug, Customer Sample Evaluation, Line Establishment Evaluation and Documentation.
- Test Planning (Hardware design, Schematic making, PCB checking before PCB fabrication)
- Hardware design base on Test specification requirement given by designer and check Specification if proposed tester can measure the required specification.
- Make Schematic base on ATE equipment and make necessary module if need to add like RC filter, IV converter, DAC unit.
- Check PCB lay out base on schematic. Compare to designer evaluation board so that characteristic could be the same as designer evaluation data.
- Develop test program in STIL, Assembly, C++ Language format using multi file editor or Microsoft based [ATE: Rohm Spandix (RSX5000), in-house tester (ICT2000, ICT8000, ICT1800)]
- Confirm Test program by troubleshooting/debugging using test console, multimeter, oscilloscope, Rohde and Schwartz Analyzer, Logic Analyzer.
- Analyze and verify each test parameter and compare to JIGU data of designer.
- Assessed test program and sample for accuracy and reliability.
- Check waveform of each pin and do as much as possible reduce surge that is over the maximum withstand voltage. Check program sequence to reduce voltage and current surge.
- Evaluate data gathered if appropriate for mass production through statistical methodology to obtain high reliability testing.
- Support production during CS and pilot measurement. Debug device under production environment or machine set up.
- Experience with Class D amplifier device, Sound Processor, DAC testing.
- Class D amplifier (Analog input, digital audio input(I2S))
