For modeling the electrical behavior of neuronal membranes with the finite element method, COMSOL Multiphysics is widely used as simulation software. In this work, we present a novel approach to model the electrical behavior of the neuronal membrane using the finite element method in ANSYS. We create a simplified and a full version of a neuron-electrode interface and compare the results. Since the simplification shows prominently different behavior, we conclude, that the simplification we made is not permissive.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116563935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resulting smaller transistors are more prone to high-energy irradiation. This is relevant in avionics or even automotive, where the safety of millions of cars must be ensured. This paper proposes an experiment, where multiple FPGAs (Field Programmable Gate Arrays) are exposed to 2.45MeV neutron irradiation in parallel. Bitflips in different memory components (Block RAM, Flip-Flops, lookup-tables and configuration memory) are detected. The results show that bitflips could be detected in every memory component in every part of the FPGA. Finally, a soft-error probability model depending on the irradiation fluence can be determined. With the probability model, future implementations of fault-tolerant hardware architectures can be tested with hardware simulations using artificially generated bitflips.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116282196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite element analysis is commonly used to build models for electronic packaging products. However, simulation errors may arise due to differences in physical concepts and considerations among researchers. To overcome this challenge, we create a database through validated finite element models and combine it with machine learning. In the domain of machine learning models, training time is a crucial research focus. Nevertheless, grid search time is often overlooked, despite its significant impact on machine learning model efficiency. To address this issue, this study utilizes parallel computing to explore the search for optimized hyperparameters in the context of the Wafer Level Chip Scale Package (WLCSP) as a case study. Additionally, custom empirical formulas are utilized to enhance the efficiency of grid search methods, thereby improving the time-to-market and competitiveness of packaged products.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122272837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These panels can be made in larger formats and better utilize the space due to the rectangular shape. However, with the larger format, warpage of the panels increases and remains a challenge in Fan-Out Panel Level Packaging (FOPLP) production. Warpage occurs mainly due to the multitude of materials that undergo multiple production steps at different temperatures, which leave residual stresses induced by mismatch of thermal strains and strains due to chemical processes (e.g. cure shrinkage). These superimposed effects and the complex material behaviour still make it challenging to predict warpage numerically and control warpage during production [2], [3]. In this work, warpage of nine different variants of a 300 × 300 mm2 panels with dummy dies have been investigated experimentally and numerically. It has been shown that the numerical model can replicate warpage of the panels and the potential for numerically supported warpage adjust steps in the fabrication of the panels has been demonstrated.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131692643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its spatial limitation and high density of NAND packages and other electrical components, however, the BGA-type packages in E1.S enclosure-type SSD suffer from low thermal cycle reliability induced by creep of solder joint, especially in the case of packages near physical constraints like screw joints. In this study, we use Finite Element Analysis (FEA) to estimate the risk of solder joint crack of NAND BGA solder balls near the screw joint in E1.S enclosure-type SSD. The plastic work per cycle on each solder was calculated by FEA and compared to the Dye-and-Pry results of the real SSD sets after thermal cycle test (- 40~85°C) to evaluate the relationship between thermal fatigue life of solder balls and the plastic work. We confirm that the mechanical restraint near the screw joint is the major cause of the reduction of the solder ball fatigue life in the E1.S SSD. Further, we suggest the optimal layout for package placement and housing design to improve thermal cycle by up to 51%, as a design rule of E1.S form factor.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128848356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the later application, the PCB carrying the package may be constrained due to the mounting in a housing, which can adversely affect the solder joint fatigue lifetime. Solder joint fatigue simulation can be used as tool along the value chain to anticipate in an early phase a potential degradation of the solder joint lifetime and to evaluate countermeasures, such as a different placement of the package on the PCB inside the housing. The accuracy of the simulation will depend on the quality of the package model passed along the value chain. This paper studies for a discrete power package different types of material modeling which could potentially be communicated along the value chain and their impact on the accuracy of the prediction. All investigated descriptions correctly identify the most critical mounting positions of the discrete power package inside a generic model of an electronics control unit (ECU). The highest accuracy of the prediction is obtained with a non-linear and temperature-dependent material description of the package, followed by an approach using homogenized blocks with effective non-linear material properties are used. For linear-elastic properties, high deviations w.r.t. the non-linear case are observed in case constant properties over temperature are used and the glass transition region of polymers is passed though in the temperature profile of interest. Linear-elastic temperature-dependent properties are identified to be more accurate than linear-elastic constant properties, but are found to deviate in their estimations up to 25% compared to the non-linear material modeling.","PeriodicalId":425592,"journal":{"name":"2023 24th International Conference on Thermal, Mechanical and Multi-Physics Simulation and Experiments in Microelectronics and Microsystems (EuroSimE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124106351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have used the “apparent heat capacity” method to model this melting, which considers the latent heat and the needed absorbed energy during the fusion.
