Published on Leave a comment on Thermal interaction of a shunt resistor and the traces

In Bodo's Power Magazine I immediately noticed a picture in an article by ROHM's Trevis Moench which shows a resistor connected to the traces on the wide side and on the short side. How much does turning the resistor by 90 degrees for the temperature and what is the contribution of the trace? This is explained in a new WhitePaper #14. Let yourself be surprised!

Thermo-Electric Circuit Board Simulation with

TRM3.7

Components and currents heat the PCB (assembly) - but how hot will it get? Are the temperature limits complied with? No data sheet or guideline will tell you.

With TRM (Thermal Risk Management) you are able to calculate the thermal performance of your circuit board before the laboratory test

… and with new TRM 3.7 it's even easier to generate a better temperature forecast. Made easier than with add-ons of the big EDA vendors.

• Import your Gerber, placement, drill files or netlist or set the necessary    data manually (see FAQ)

• 3D circuit board model with up to 50 layers

• Update: Easy export and import for ALTIUM users

• NEW:       Easy export and import for EAGLE users

• Clearly arranged operation

• Templates and file formats for parameter input

• Can also be used without CAD data - for technologists

• No FEM knowledge required

________________________________________

• Accuracy through physics and geometry

• Heating by components and/or currents

• Environmental conditions. Air cooling, heat sinks and heat sinks, radiation into a vacuum, and much more

• Virtual thermograms of all layers and prepregs in high resolution

• DC potential distribution and current density in nets

• Steady-state or transient

• Temperature-dependent material data

• Self and mutual inductance (inductance matrix)

• Automatically generated result tables

• Licensing by your server

• Short to moderate computing time on laptop and PC

Published on Leave a comment on TRM, the better PCB thermal simulation tool for EAGLE/Fusion users

Good news for board designers using Autodesk's EAGLE or Fusion 360!

Transfer board data in 2 clicks and start a thermal simulation with TRM. The first action starts a special export, the second one an import wizard in TRM. Layer stackup, holes, netlist and components are automatically merged into an assembly model. Then just assign the most relevant Watts and/or Amps - done.

Published on Leave a comment on TRM 3.6 released: 10x faster

Printed circuit boards with many layers, fine x-y resolution or large "pie trays" pose a numerical challenge. Up to now it was like this: the more temperature nodes to solve, the more iterations were required and it was not unlikely that unstable convergence would occur (has been got under control by internal repair mechanisms).

With Release TRM3.6, a new "Turbo" algorithm has been added, which solves the 3D temperature field about 10x faster than before. By activating multi-threading, you can possibly get even more out of it. Really demanding projects are now completed in tens of minutes instead of one or more hours.

My friend and colleague Doug Brooks has decided to take retirement. Therefore he has summarized his best articles and parts of his books in a new work "UltraCAD's Best".

Also, his calculation tools are now available for FREE instead of $250:
