Job Description

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
