The role of a heatsink is to provide a conduction path from a heat source that is to be cooled to a volume of cooling fluid. The heatsink’s surface area that fills that volume is considerably larger than the surface area of the heat source. In this way, the heatsink acts as an ‘area extender’. For a given heat flow (Q) and convective heat transfer coefficient (h), any … [Read more...]
Generative Design for Electronics Cooling
Co-Authored by: Danny J. Lohan, Yuqing Zhou, and Ercan M. Dede Toyota Research Institute of North America INTRODUCTION Generative design is an iterative design process that involves the use of a program to generate a set of optimized designs that meet product performance requirements and constraints. Methods that transform statements of performance requirements into … [Read more...]
Protect Electronic Components with Dam & Fill
Sensitive electronic components mounted on a circuit board often require protection from exposure to harsh environments. While there are several ways to accomplish this, the dam and fill method offers many benefits. Dam-and-filling entails dispensing the damming material around the area to be encapsulated, thereby restricting the flow of the fill from spreading to other parts … [Read more...]
