• Drive Die Bond process optimization improves yield, eliminates defects, and enhances equipment utilization.

• Establish and maintain critical process controls for die placement accuracy, bond line thickness, epoxy coverage, void performance, die shear strength, and overall package reliability.

• Lead root cause analysis and corrective actions for Die Bond-related quality excursions using 8D, DMAIC, Fishbone, DOE, and statistical methodologies.

• Develop and execute process qualification plans for new materials, equipment, packages, and technology transfers.

• Partner with Equipment Engineering to improve machine capability, preventive maintenance strategies, uptime, OEE, and MTBA performance.

• Lead NPI and package transfer activities involving Die Bond process development, validation, and volume ramp-up.

• Monitor and improve key Die Bond KPIs including:

• • Die Placement Accuracy

• • Epoxy Coverage Performance

• • Voids Performance

  • Die Shear Strength

  • Yield Loss

  • OEE

  • MTBA

  • Customer Complaint Rate

• Drive process characterization activities using DOE and statistical analysis to define process windows and improve robustness.

• Ensure compliance with IATF16949, customer requirements, Control Plans, PFMEA, SPC, and other quality management system requirements.

• Lead customer audits, qualification reviews, failure analysis discussions, and technical presentations related to Die Bond processes.

• Build technical competency of engineers, technicians, and operators through training, coaching, and mentoring.
