SMT Maintenance Technician

Position Summary

We are seeking a high-caliber, floor-focused Senior SMT Equipment Maintenance Technician to oversee the electromechanical health, maintenance, calibration, and repair of our automated surface mount technology lines. This role centers on real-time troubleshooting, defect reduction, and preventative maintenance across the full line—from solder paste print to reflow.

The ideal candidate possesses deep, hands-on mechanical and process troubleshooting and machine repair experience with the ability to calibrate Mycronic / MyData pick-and-place machines, ensuring maximum uptime and yield without programming responsibilities.

Key Responsibilities

• Real-Time Diagnostics: Respond instantly to floor-down calls, performing advanced electromechanical and pneumatic troubleshooting on Mycronic MY-series machines during active production runs.

• Mispick & Reject Reduction: Analyze machine error logs and vision system data on the floor to eliminate component mispicks, dropping, or tombstoning caused by mechanical wear or feeder misalignment.

• Magazine and Feeder Maintenance: Diagnose, teardown, repair, and calibrate feeders and linear magazine tracks to guarantee flawless component indexing and pitch.

• Solder Paste Printer Machine: Troubleshoot, repair, calibrate, and adjust setups to ensure accurate printing.

• Reflow Oven Profiling & Maintenance: Maintain multi-zone reflow ovens. Assist engineering with running thermal profiling sweeps (using KIC/SlimKIC) on the floor, and troubleshoot heating zone elements, blower motors, and conveyor chain tracks.

• Process Tuning: Adjust machine parameters on the fly (e.g., nozzle pick heights, camera lighting thresholds, vacuum pressures, or printer snap-off) to resolve process variations caused by PCB warpage or varying component packaging.

• X/Y/Z Calibration: Use specialized jigs and calibration software to mechanically align X, Y, and Z axes, ensuring placement accuracies within micron tolerances.

• Preventative Maintenance (PM): Lead scheduled daily, weekly, and monthly PM cycles across the entire line, replacing worn belts, bearings, O-rings, and filters to prevent catastrophic floor failures.

Required Qualifications & Skills

• Experience: 5 years of automated SMT line maintenance and troubleshooting with a minimum of 4 years dedicated directly to Mycronic / MyData platforms.

• Print & Thermal Aptitude: Hands-on experience repairing all devices in solder paste printer, and high-temperature oven conveyor systems.

• Mechanical & Pneumatic Mastery: Strong hands-on mechanical aptitude with miniature automated assemblies, precision bearings, linear rails, and low-pressure pneumatic systems.

• Schematic Reading: Strong ability to read and interpret complex electrical schematics, pneumatic and vacuum diagrams, and mechanical blueprints.

• Tooling Proficiency: Expert use of precision measurement tools including dial indicators, micrometers, multimeters, and calibration jigs.

Preferred Qualifications

• Associate degree in Electronics, Mechatronics, or equivalent military training.

• Skilled in using the tools and equipment needed to perform these tasks.

• Certified maintenance training directly from Mycronic or a major SMT equipment manufacturer.

• Basic understanding of IPC-A-610 standards
