Presentation Title: Warpage simulation analysis of the pre-baking process in system-in-package assembly 

Reflection

Through this CSME conference, I was able to practice presenting my research before the oral defense. From introducing the topic to explaining the overall framework and finally summarizing the study, I gained valuable experience in organizing my presentation logic and pacing. Moving forward, I will continue discussing subsequent process conditions to further refine the SiP process simulation. I also plan to include analyses of fracture stress and lid-type packaging, aiming to reduce warpage even further based on the current foundation.

Effect of Anti-Aging Coatings and Accelerated Aging under Constant Temperature and Humidity on the Mechanical Properties of Natural Fiber Composites  

Natural fiber composites are lightweight and environmentally friendly, but they are prone to aging and weakening due to environmental factors such as temperature and humidity. In this study, an anti-aging coating is applied to the material surface, and accelerated aging tests under constant temperature and humidity are conducted to simulate long-term use. The focus is on comparing the mechanical strength of the material before and after aging, and evaluating whether the coating can effectively slow down aging and improve durability.

Effect of Adding Carbon Nanofillers to Adhesives on the Fatigue Strength of Dissimilar Material Joints 

This study investigates whether adding carbon nanofillers to adhesives can enhance the fatigue strength of dissimilar material joints. Carbon nanomaterials possess high strength, high stiffness, and good dispersibility; incorporating them can improve the mechanical properties of the adhesive layer and reduce crack propagation.

Presentation Title: Feasibility Assessment of the Vibration Behavior Model for Substrate-Stepped Modules 

Reflection

Through the preparation process for the 2025 ISME National Academic Conference, I was able to refine the structure of my oral defense presentation one and a half months in advance. This also gave me the opportunity to evaluate my current grasp of the thesis content and reflect on whether my understanding of the research's value is solid.

Although the preparation period coincided with the National Intercollegiate Athletic Games, making my schedule tighter than usual, prior experience with industry-academia collaboration, along with daily post-competition efforts and mutual learning with my advisor and lab mates, enabled me to complete a relatively comprehensive presentation just one day before the conference.

I have now formed a preliminary framework covering the research background, the integration from wafer-level to board-level modules, a literature review, and the novelty of my work. The next step is to complete the collection of remaining DOE data and proceed with results and discussion, which will further enhance both my finite element evaluation model and the AI-based prediction model. I will also continue to prepare for potential questions from the oral defense committee.

In summary, I treated this ISME conference as a rehearsal for my oral defense. While the preparation time was short, I aimed to build a solid structure and content. I believe my performance was acceptable, though there are still many details to refine. I sincerely thank my advisor and fellow lab members for their guidance and support. I will continue working toward successfully passing my thesis defense.
