Electrical Reliability Test Technician

Job Description

Job Summary:

Onsemi is seeking an Electrical Reliability Test Technician to specialize in the execution and monitoring of electrical stress protocols for semiconductor devices at our Arizona Tempe/Scottsdale Rel Lab operations. This role focuses on characterizing device stability under extreme electrical conditions—specifically high-voltage, high-current, and transient power events. You will bridge the gap between hardware setup and data acquisition, ensuring that electrical stress is applied precisely according to JEDEC and internal specifications.

Responsibilities

Core Responsibilities

• Electrical Stress Execution: Set up and manage advanced electrical stress tests, including High-Temperature Operating Life (HTOL), Early Life Failure Rate (ELFR), Power Cycle Test, and Dynamic Burn-in.
• Precision Electrical Characterization: Perform pre- and post-stress I-V (current-voltage) characterization using Curve Tracers and Source Measure Units (SMUs) to detect subtle parametric shifts.
• Power Integrity Monitoring: Utilize Oscilloscopes and Logic Analyzers to monitor power rails and signal transitions during stress testing to ensure the "stress" remains within specified tolerances.
• Failure Data Acquisition: Monitor "in-situ" electrical data during long-term stress runs. Identify and log anomalies such as thermal runaway, voltage spikes, or unexpected current consumption.
• Test Hardware Validation: Verify the electrical integrity of Burn-in Boards (BIBs) and test sockets. Perform continuity and isolation checks to ensure hardware does not introduce electrical noise or artifacts into the data.
• Documentation & Reporting: Maintain precise logs of electrical parameters (Vdd, Icc, etc.) and generate initial delta-reports comparing pre-stress and post-stress electrical performance.
  
  

Qualifications

QUALIFICATIONS

• Experience: 3 years of experience in a semiconductor lab environment or reliability testing facility.
• Technical Skills: Familiarity with JEDEC/ESDA standards for component reliability. Ability to read schematics and use standard lab tools (Oscilloscopes, DMMs, Curve Tracers).
• Experience operating reliability stress tools (HTOL, ELFR, HAST, Temperature Cycling, etc.).
• Education: Associate’s degree in Electronics, Electrical Engineering Technology, or a related field (or equivalent military/technical training).
• Attributes: High attention to detail, strong safety mindset when handling sensitive components, and the ability to work independently in a fast-paced lab.
• Effective communication and teamwork abilities.
• Commitment to safety, quality, and continuous improvement.
