• Verify and adjust process parameters to ensure compliance with MPIs, ECOs, and customer requirements.

• Perform line changeovers, feeder setup, stencil installation, and program verification.

• Monitor line performance and proactively address issues impacting yield, quality, or throughput.

Troubleshooting & Process Control

• Diagnose and resolve SMT process defects such as insufficient/excess solder, tombstoning, skew, bridging, and placement errors.

• Support root cause analysis and corrective actions for SMT-related defects.

• Work closely with Quality and Manufacturing Engineering to implement process improvements.

• Perform first article verification and assist with line qualifications and validations.

NPI & Engineering Support

• Support new product introductions (NPI), engineering builds, and pilot runs.

• Provide feedback on DFM/DFA issues and assist with process optimization.

• Assist with stencil design feedback, component package challenges, and placement strategies.

Quality & Compliance

• Ensure all SMT processes comply with IPC-A-610, IPC-J-STD-001, and customer specifications.

• Maintain ESD, MSD, safety, and housekeeping standards.

• Accurately document process changes, deviations, and pass-downs.

Training & Mentorship

• Train and support SMT operators on proper setup, operation, and best practices.

• Serve as a technical resource for operators and leads during shifts.

• Promote standard work and consistent process execution across all SMT lines.

Required Qualifications

• High school diploma or equivalent required; technical training or certification preferred.

• 3+ years of hands-on SMT experience in a PCBA manufacturing environment.

• Strong working knowledge of SMT processes, components, and materials.

• Experience with SMT equipment (pick-and-place, printers, reflow, AOI).

• Ability to read and interpret MPIs, schematics, BOMs, and assembly drawings.

• Familiarity with IPC standards (IPC-A-610, J-STD-001 preferred).

• Strong troubleshooting, analytical, and problem-solving skills.

Preferred Qualifications

• • IPC-A-610 and/or J-STD-001 certification.

• • Experience in high-mix, low-to-medium volume manufacturing.

• • NPI and engineering build support experience.

• • Exposure to AOI programming, feeder maintenance, or stencil optimization.

• • Lean manufacturing or continuous improvement experience.

Skills & Competencies

• • Attention to detail and commitment to quality.

• • Ability to work independently and prioritize tasks in a production environment.

• • Strong communication and teamwork skills.

• • Comfortable working in a fast-paced, deadline-driven setting.

• • Willingness to support flexible schedules or off-shift builds as needed.

• Physical & Work Requirements

• • Ability to stand for extended periods.

• • Ability to lift up to 30 lbs.

• • Frequent use of hand tools and fine motor skills.

• • Work in a manufacturing environment requiring ESD compliance.

• Pay Range

• $33—$33 USD
