Set up, operate, and support SMT equipment including solder paste printers, pick-and-place machines, reflow ovens, AOI, and supporting automation.
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
