Senior or Staff IC Packaging Engineer - Mechanical Simulation

优缺点分析

角色解读

• Advance to Principal/Lead Engineer or technical fellow within Qualcomm's packaging engineering ladder.
• Opportunity to drive R&D for next-generation packaging technologies (e.g., 3D IC, heterogeneous integration).
• Potential transition to broader roles in chip-package co-design or system-level thermal/mechanical simulation.
• Build and run finite element models (ANSYS APDL/Workbench) to simulate warpage, stress, and solder joint reliability for IC packages.
• Collaborate with design, NPI, and CPI teams to provide mechanical simulation insights for current and future chipsets.
• Develop and maintain FEA methodologies, macros, and best practices to improve prediction accuracy and test correlation.
• Strong proficiency in ANSYS APDL and Workbench for mechanical FEA.
• Deep understanding of semiconductor packaging structures, materials, and assembly processes.
• Experience with advanced FEA techniques (sub-modeling, contact analysis, non-linear analysis) and material characterization.
• Analytical problem-solving skills and ability to communicate complex simulation results effectively.

申请策略

• Tailor your resume to include specific projects where your FEA work impacted product design or reliability.
• During the interview, be prepared to discuss your approach to model validation and correlation with test data.
• Emphasize hands-on experience with ANSYS APDL/Workbench and specific packaging simulations (warpage, SJR, CPI).
• Showcase any material characterization or test correlation projects that improved model accuracy.
• Highlight publications or research in FEA predictive modeling for packaging.
• Demonstrate ability to work in cross-functional teams and manage multiple projects.
• If not already proficient, practice ANSYS APDL scripting and Workbench automation.
• Deepen understanding of semiconductor packaging materials and processes.

面试指南

• For technical questions, explain the physics behind the problem, your modeling assumptions, and how you validate results.
• Describe a complex FEA simulation you performed for an IC package. What challenges did you face and how did you overcome them?
• How do you ensure your simulation results correlate with actual test data?
• Explain the key factors affecting solder joint reliability in a flip-chip package.
• How would you model the warpage of a large organic substrate during reflow?
• What is your experience with material characterization techniques for packaging materials?
• Review fundamental concepts in IC packaging: materials, assembly processes, reliability tests.
