Key Responsibilities
  • Develop, validate, and improve SMT assembly processes including solder paste printing, pick-and-place, reflow.
  • Establish and maintain process parameters, work instructions, control plans, and standard operating procedures.
  • Lead process characterization (DOE, capability studies) to ensure robust and repeatable manufacturing performance.
  • Provide day-to-day engineering support to production lines to resolve yield, quality, equipment, or throughput issues.
  • Analyze process data and defect trends using SPC and root-cause analysis tools to drive corrective actions.
  • Support ramp-up of new products from NPI through full production.
  • Drive defect reduction initiatives targeting solder defects, component damage, alignment issues, and functional failures.
  • Support PFMEA creation and maintenance for PCBA processes.
  • Collaborate with Quality Engineering on customer complaints, audits, and corrective/preventive actions.
  • Define equipment requirements and support selection, qualification, and deployment of SMT and PCBA manufacturing equipment.
  • Work with maintenance and vendors to optimize equipment performance, uptime, and reliability.
  • Specify and validate fixtures, stencils, solder profiles, and tooling.
