TRM3 - add it to ZUKEN eCADSTAR

Currents heat up a printed board assembly in the components and conductor traces. TRM is the simulation software for a detailed check of the expected temperature (currents, component heating, cooling to the environment, etc.), allowing you to calculate the thermal risks of your PCB before laboratory testing.

Transfer design data from eCADSTAR von ZUKEN.

All necessary information can be found here: CSK (all languages)

The TRM tool should therefore be regarded as a power distribution network (PDN) plus thermal analysis tool performing 3D temperature calculations for you. To ensure that this process is as secure and user-friendly as possible eCADSTAR is intefaced with TRM. CSK has created scripts so that users can export all relevant design data from eCADSTAR into the TRM software with a single click, allowing the thermal simulation to be started.

This makes TRM well suited for beginners.
Experts will find many interesting options for advanced situations.

 

 

A new study focuses on the EVAL-LTM4703-AZ evaluation board, a high-efficiency, dual-channel μModule® regulator capable of delivering up to 12A.

Detailed study about a PCB with switching regulator

The compact design and high-power density of this regulator make it an ideal candidate for analyzing thermal challenges in switching regulators. By bridging theoretical modeling, experimental validation, and simulation, this work comprehensively assesses temperature rise and associated phenomena. Methods to calculate power losses, measure thermal profiles under operational stress, and simulate heat distribution using TRM software are presented.

Test it yourself. Just ask your ZUKEN reseller, CSK or ADAM-Research for licenses and test installation. Or contact your local Zuken office or reseller.

In Bodo’s Power Magazine ist mir in einem Beitrag von ROHM’s Trevis Moench sofort ein Bild aufgefallen welches einen Widerstand in breitseitigem und in schmalseitigem Anschluss an die Leiterbahnen zeigt. Wieviel bringt das Drehen des Widerstands für das Thermal Management wirklich für die Temperatur und was ist der Beitrag der Leiterbahn? Darüber wird in einem neuen WhitePaper #14   aufgeklärt. Ich habe gestaunt.

New  White Paper #13: "How effective are thermal vias? Less than you think"

Doug Brooks: "Stop thinking about current density!"
