Solder connections are one of the most essential parts of the PCBs. Despite many well-known scientific works that have been done about overlap solder interconnection properties, such as fracture, fatigue and reliability studies, little attention have been given to the investigation of the connection between effects of electrical properties and laboratory soldering shortages such as effects of ...

This poster presents an evaluation study of a couple of heat trap designs, analyzing the generation of Joule heating and heat dissipation characteristics. Through parametric simulations of the heat traps varying geometries, it is possible to see the generated temperature difference at a constant current. Simulating a soldering process, the heat traps are tested on time dependent studies to see ...

In this paper the development of a COMSOL® app for the engineering design of thermal quality clothing has been started. The software architecture is developed for different design strategies. Specific design requirements lead to different simulation models for the clothing wearing system ranging from simple 1D, 2D to complex time-consuming 3D models. The COMSOL app uses finite element method ...

A comprehensive three dimensional finite element thermal model has been developed using COMSOL Multiphysics® software to understand the thermo-physical behaviour of the uppermost regolith layer of the moon. The model can simulate variable layers, layer thickness and dimensions and can account for complex geometry, different size, irregular meshing, parametric based variation in physics and ...

Microfluidics is the science of manipulating and controlling fluids at the micron scale. Although, fluid flow in standard geometries can be determined easily by analytical methods, a more rigorous computational model is required for custom geometries. Achira’s microfluidics cartridge has a microchannel with intricate curvatures to allow the entrapment of biosensors. The number and dimensions of ...

Micro electrical discharge machining (MEDM), a scaled down version of EDM process, is a micro machining process used to fabricate micro holes and intricate shapes in electrically conductive materials irrespective of its hardness. In this process, an electric spark is generated in the gap between the two electrodes (tool as cathode and workpiece as anode) submerged in dielectric that leads to a ...

The present work formulates the dynamics of a slender structure as a long beam. This results in a PDE that is fourth-order in space, and second order in time. In COMSOL the coupling method is used to decompose this problem into two second-order equations, one for displacements, and one for bending moments, which are then solved to obtain frequencies and mode shapes. For verification of ...

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...
