Machine Operator - SMT

As an SMT Operator at Rocket EMS, you will play a critical role in building high-reliability PCB assemblies by setting up, operating, and monitoring SMT production equipment. You’ll run screen printers, SPI, pick-and-place machines, and reflow ovens to ensure every build meets IPC-A-610 Class 2 and 3 workmanship standards. This position requires strong technical aptitude, attention to detail, and the ability to follow precise build documentation in a fast-paced electronics manufacturing environment.

Responsibilities

• Review build documentation such as MPIs, assembly drawings, ECOs, BOMs, and customer requirements before beginning work.

• Set up and operate SMT equipment including:

  • Screen printers

  • Solder paste inspection (SPI) systems

  • Pick-and-place machines (Fuji, Panasonic, Juki, etc.)

  • Reflow ovens

• Verify feeder setups, component orientation, reference designators, and correct loadouts according to the BOM.

• Perform machine program loading, verification, and first-article checks as required.

• Monitor machine performance, address mis-picks, placement errors, and stoppages promptly, and escalate recurring issues to the Lead, Engineer, or Supervisor.

• Conduct visual and AOI pre-verification to ensure solder paste deposits, component placements, and reflow results meet IPC-A-610 standards.

• Perform basic machine maintenance, cleaning, and calibration tasks according to established procedures.

• Assist in first article builds, ensuring accuracy of placements, polarity, and component values.

• Identify and correct SMT-related defects; escalate systemic issues to Engineering or Quality.

• Maintain clean, organized work areas and follow all ESD, MSD, and handling procedures.

• Record production data, downtime events, and pass-down information accurately.
