Introduction

The Test Troubleshooter is responsible for testing, analyzing, troubleshooting, repairing, and validating complex printed circuit board assemblies (PCBAs) and box-build electronic products. This position supports In-Circuit Testing (ICT), Functional Testing (FCT), Environmental Chamber Testing, and customer-specific test processes. Using schematics, engineering documentation, test procedures, and diagnostic equipment, the Test Troubleshooter identifies root causes of failures and performs component-level repairs to restore products to full compliance with customer, regulatory, and quality requirements.

The ideal candidate possesses strong analytical and troubleshooting skills, is proficient in interpreting electronic schematics and test data, and is certified or capable of certification to IPC Class 3 workmanship standards. The role requires independent decision-making, effective communication with Engineering, Quality, and Production personnel, and a commitment to achieving customer quality and delivery objectives.

Key Responsibilities

Essential Duties and Responsibilities

• Operate and support In-Circuit Test (ICT), Functional Test (FCT), Environmental Chamber Testing, and other customer-specific test platforms.
• Analyze test failures using schematics, wiring diagrams, assembly drawings, bills of material, and engineering documentation.
• Perform component-level troubleshooting to isolate root causes using systematic diagnostic methods.
• Utilize electronic test equipment including Digital Multimeters (DMM), oscilloscopes, spectrum analyzers, power supplies, signal generators, frequency counters, and other diagnostic tools.
• Interpret analog, digital, RF, and mixed-signal circuits and associated test results as applicable.
• Perform Class 3 soldering, rework, and repair of through-hole and surface-mount electronic assemblies in accordance with IPC standards and customer requirements.
• Document troubleshooting activities, repair actions, root cause findings, and test results in manufacturing and quality systems.
