NPI Senior Process Engineer

To develop, optimize, qualify, and establish robust semiconductor assembly processes for REXFET products, covering Resin Tie Bar Cut, Strip Grinding & Cut Form Mark process. The role is responsible for process development, optimization, qualification, technical problem-solving, and manufacturing readiness to ensure new products meet quality, reliability, productivity, and cost requirements.

The engineer will work closely with NPI project management, Production, Process Engineering, Equipment Engineering, Quality Assurance, Product Engineering, Material Engineering, and other cross-functional teams to ensure successful product introduction and smooth transfer to mass production.

Key Responsibilities

A. NPI Process Development and Qualification

• Develop, establish, and optimize assembly process conditions for new REXFET products.
• Prepare and execute process development plans, engineering & qualification builds, and process validation activities.
• Establish process parameters, specifications, control limits, and acceptance criteria.
• Evaluate process feasibility, identify potential manufacturing risks, and implement preventive actions before mass production.
• Review process capability, yield performance, defect trends, and qualification results.
• Prepare technical reports, process documentation, and qualification summaries.
• Support safe launch activities and ensure all critical process issues are resolved before mass production release.
B. Multi-Process Engineering Responsibilities

• Resin Tie bar cut - Develop and optimize Resin Tie bar cut process for REXFET
• Strip Grinding - Develop and optimize Strip Grinding process for REXFET
• Cut Form Mark - Develop and optimize Cut Form Mark and other related process control for Marking & Cutting.
C. Cross-Functional Collaboration

• Collaborate with Production, Equipment Eng, QA, Product Eng, Material Eng, and other relevant departments
• Work with equipment and material suppliers to evaluate new technologies and improvement opportunities.
• Provide technical support during engineering builds, qualification builds, troubleshooting, and production ramp-up.
• Coordinate process readiness, material availability, and documentation before qualification and mass production.
D. Documentation and Mass Production Transfer

• Prepare and maintain process specifications, SOPs, work instructions, process flow documents, and risk assessments.
• Maintain engineering records, process parameter histories, DOE results, and qualification reports.
• Support PFMEA reviews and implementation of appropriate process controls.
• Define critical-to-quality parameters and monitoring requirements.
