3D Thermal Simulation Of Resistive Heating

Joule heating, also known as resistive or Ohmic heating, is the power lost to heat as electrical current flows down a conductor. We were introduced to Joule’s first law (Power dissipation = I²R, VI, ...

Thermal Simulation Of DSMBGA And Coupled Thermal-Mechanical Simulation Of Large Body HDFO

Electronic packaging has continued to become more complex with higher device count, higher power densities and Heterogeneous Integration (HI) becoming more common. In the mobile space, systems that ...

Thermal management: A close look at vertical heat flow in PCBs

In a previous article, “A Close Look at Facts and Myths About Thermal Vias,” we used a thermal simulation model called Thermal Risk Management, or TRM, to model thermal vias. Thermal vias, almost by ...

Move Your Thermal Strategy For Air-Cooled Electronics Up In The Design Flow

There are two golden rules to thermal design: start simple and start early. The heat-flow path from the junction to the ambient, usually air in the local environment, determines a component’s ...
