Nattaphat Promsuwanna

• Bring up and qualify the new testing system (ComET) to support across key products for the electrical testing functionality.
• Develops and improves test algorithm to provide a robust test suite and test time reduction for the production requirements.
• Provides data analysis reports about the meaning of gathered testing data to team and help them identify problems.
• Failure analysis support to help team understand the cause of failure and create the procedure to prevent or minimize the failure.
• Highlight project:
  Mini-Deck Acceptance: Develops a testing processes to qualify a testing unit called mini-deck by using regression and hypothesis testing. This significantly reduces complexity compared to the conventional process resulting in very high throughput but still provide good effectiveness.
  Noisy contact detection profile detection: Optimizes the regression for the contact profile to calculate noise signal, the magnitude of noise signal is used to quantify how contamination impact to the test result.

• Works on 1st level testing system problems and troubleshooting for both development and production in Thailand, especially for Hybrid Testing System (HTS).
• Provide a test solution for production and development testing systems.
• Works as coordinator with US team (both Seagate and Guzik) for the second level testing system troubleshooting.
  Performed defect tracking & management in JIRA.
• 3 months training as a system engineer at GUZIK Technical Enterprises (California, USA) and Seagate Technology (Minnesota, USA).
• Highlight project:
  Micro-Actuator Servo: Develops a standard practice for micro-Actuator servo testing, this enables a very high TPI (Track Per Inch) product capability on the conventional tester.
  HAMR multi-zone format media: Develop standard practice and functionality test script for HAMR (Heat-Assisted Magnetic Recording) format media process. This significantly reduces format media failure on HAMR and improves servo quality.

• Develops and optimizes head characteristic test to provide the best test solution to production team.
• Provides a proper data analysis report from the testing result to R&D team in US to convert data into actionable insights.
• Works in Thermo-Mechanical area to understand and develop a contact detection technique, provides the best settings and failure analysis related with contact detection.
• Highlight project: Develops an acoustic signal testing script to understand mechanical stability problem in a new suspension design.

Works in special project for HDD testing called Short Test time Script (STS) to capture a failure drive faster before going to normal production testing, this significantly improves production yield which usually takes very long testing time before the failure is detected. Responsible for test optimization and data analysis.
