Robot Repair Technician

Responsibilities

• Troubleshoots, diagnoses, repairs, and tests semiconductor industry robotic systems at the system, module, and subassembly level.
• Equipment includes wafer-handling and atmospheric robot systems manufactured by Cybeq, PRI Equipe, Brooks Automation, Kensington Labs, and similar platforms.
• Diagnose controller faults, motion issues, alignment problems, vacuum and end-effector issues, encoders, motors, power distribution, safety circuits, and cabling.
• Performs functional and motion testing, alignment checks, and system verification when possible to confirm proper operation.
• Troubleshoot and diagnose semiconductor robot systems used for wafer handling, transfer, and positioning.
• Repair or replace robot assemblies and modules including controllers, power supplies, servo drives, motors, encoders, amplifiers, vacuum end-effectors, sensors, and cabling.
• Diagnose robot motion faults such as positioning errors, homing failures, repeatability issues, encoder faults, communication errors, and vacuum faults.
• Perform mechanical adjustments, alignment, and calibration to restore positional accuracy and repeatability within required tolerances.
• Inspect, repair, or replace robot cabling, flex cables, connectors, and harnesses.
• Utilize diagnostic tools including multimeters, insulation testers, alignment tools, and manufacturer-provided diagnostics or service software when available.
• Read and interpret wiring diagrams, block diagrams, system schematics, fault codes, service manuals, and customer documentation.
• Perform functional testing, dry runs, and limited motion verification in controlled environments to validate repairs.
• Document diagnostics, repair actions, replaced modules, and test results in the designated system.
• Communicate equipment status, technical findings, and repair timelines with Purchasing, Engineering, Sales, Customer Service, Logistics, and IT.
• Follow all OSHA regulations and company safety policies, including electrical safety, lockout/tagout, and ESD control procedures.
• Maintain required company and customer documentation and service records.
• Maintain a clean, organized, and controlled work area suitable for semiconductor equipment.

Qualifications

• Associate degree or technical training in robotics, mechatronics, electronics, electromechanical systems, automation, or a related discipline or equivalent related industrial experience.
• Experience working with semiconductor manufacturing equipment or wafer-handling robots preferred.
• Experience with precision motion systems, servo-controlled robotics, and industrial automation equipment.
• Knowledge of semiconductor robotic systems, including wafer-handling robots, controllers, servo motors, encoders, vacuum end-effectors, and safety circuits.
• Understanding of precision motion control, alignment, homing routines, and repeatability requirements.
• Strong troubleshooting skills for system-level electrical, electronic, and electro-mechanical failures.
• Familiarity with cleanroom-sensitive equipment handling practices (ESD, contamination awareness).
• Ability to interpret wiring diagrams, system schematics, and fault documentation.
• Ability to follow detailed written procedures, service manuals, and quality standards.
• Ability to work independently while maintaining productivity, accuracy, and documentation quality.
• Effective communication skills across departments and functions.
