Core Responsibilities

Primary Functions

  • Execute the complete setup, calibration, and operation of a wide array of electronic test equipment, including oscilloscopes, multimeters, power supplies, and specialized diagnostic tools.
  • Conduct a comprehensive suite of functional, performance, and environmental tests on electronic assemblies, sub-assemblies, and final products according to detailed test procedures and engineering specifications.
  • Systematically troubleshoot and diagnose failures down to the component level, utilizing schematics, block diagrams, and technical documentation to pinpoint the root cause of any malfunction.
  • Meticulously record and document all test procedures, measurements, and results with a high degree of accuracy in a Manufacturing Execution System (MES), database, or handwritten logs.
  • Generate clear and concise non-conformance reports (NCRs) and communicate failure trends and critical issues to test engineers, quality assurance personnel, and manufacturing supervisors.
  • Interpret complex engineering drawings, electronic schematics, and written work instructions to ensure tests are performed correctly and products meet all design requirements.
  • Perform delicate rework, soldering, and component replacement on printed circuit board assemblies (PCBA) to correct failures identified during the testing process.
  • Contribute to the upkeep and basic maintenance of test stations and equipment, ensuring they remain in proper working order and calibration.
  • Adhere strictly to all workplace safety protocols, including Electrostatic Discharge (ESD) prevention procedures, to maintain a safe working environment and protect sensitive electronic components.
  • Partner with test and design engineers to provide critical feedback on product testability, failure modes, and potential improvements to the manufacturing or testing process.
  • Operate environmental test chambers to subject products to specified temperature, humidity, and vibration cycles, monitoring and recording performance under stress.
  • Interface with and operate automated test software and custom graphical user interfaces (GUIs) to execute test sequences and collect data efficiently.
  • Compile, organize, and summarize test data to support failure analysis, trend monitoring, and the creation of comprehensive yield reports for production management.
  • Perform regular verification and self-tests on test fixtures and harnesses to confirm their functionality and ensure the integrity of test results.
  • Provide valuable, hands-on input to assist engineering teams in the development, validation, and refinement of new and existing test procedures.
  • Uphold 5S principles or similar organizational standards to maintain a clean, orderly, and efficient personal workspace and shared lab environment.
  • Load firmware, configure parameters, and program microcontrollers or other programmable devices as a required step within the overall testing sequence.
  • Conduct thorough visual inspections of assemblies for manufacturing defects such as poor soldering, incorrect component placement, or physical damage prior to and after testing.
  • Manage personal workflow and prioritize testing tasks effectively to meet demanding production schedules and organizational output goals without compromising quality.
  • Communicate ongoing progress, roadblocks, and equipment status effectively during shift changes and daily team meetings to ensure smooth operational handoffs.
  • Identify and recommend opportunities for continuous improvement within the testing process to enhance efficiency, accuracy, and overall product quality.
  • Perform final system-level integration and testing of multiple sub-assemblies to verify the functionality of the complete, assembled product.

Secondary Functions

  • Assist engineering teams in building and validating new test fixture prototypes.
  • Participate in lean manufacturing and continuous improvement events and initiatives.
  • Help maintain an accurate inventory of test-related consumables, tools, and spare parts.
  • Provide peer-to-peer training and guidance to new or less-experienced Test Operators on standard procedures and equipment operation.
