Job Title
Internship - Package Mechanical Simulation
Role Summary
Internship within the Package Core Technology group to implement and validate microstructure-based simulations of solder joint behavior under mechanical and thermal loading. The role focuses on translating theoretical models into production-capable simulation code and evaluating their impact on package reliability.
Work will include algorithm development, integration into NXP's simulation environment, and validation against theoretical and experimental results.
Experience Level
Entry-level internship. Suitable for a current graduate student (Master's). No specific years of professional experience required.
Responsibilities
Primary responsibilities and deliverables for the internship include:
- Develop algorithms to simulate evolution of solder joint microstructures under mechanical and thermal loads.
- Implement theoretical models and scientific formulations into the existing simulation framework.
- Enhance simulation tools that generate realistic microstructures and assign material properties to grains and grain boundaries.
- Investigate degradation mechanisms and analyze their effect on package reliability.
- Validate models against theoretical expectations and available experimental or literature data.
- Develop validation methodologies and benchmark cases for model verification.
- Deliver documentation, a final report, and a presentation summarizing methodology, implementation, validation results, and recommendations.
Requirements
Must-have technical skills and attributes; items listed as "nice-to-have" indicate desirable additional experience.
-
Must-have: Strong interest in materials modeling, reliability engineering, computational mechanics, or semiconductor packaging.
-
Must-have: Programming and scientific computing experience in Python, MATLAB, C++, or similar languages.
-
Must-have: Ability to interpret scientific literature and translate theoretical concepts into computational algorithms.
-
Must-have: Strong analytical and problem-solving skills; attention to model validation and accuracy; good written and verbal communication for technical reporting and presentation.
