Two different package styles, two very different thermal responses when a extruded plate fin heatsink is placed on each. At the very least a FloTHERM simulation can be used to observe the thermal behaviour of…read more
Why Not Just Shove a Heatsink on Top of it? Part 1
May 13th, 2013
A common enough question. Heatsinks are often perceived to be the magic answer to all electronics cooling challenges. They should be called ‘area extenders’ as heat does not just disappear into them. Heat spreads throughout…read more
Experiment vs. Simulation, Part 5: Detailed IC Package Model Calibration Methodology
April 19th, 2013
In the royal family of thermal IC package modelling types, a detailed model is King. All critical 3D geometry is modelled explicitly, no abstraction into a thermal resistor equivalent model, no hiding all the proprietary…read more
Experiment vs. Simulation, Part 4: Compact Thermal Models
April 8th, 2013
Electronics cooling simulation was born out of the world of CFD, rather fully conjugate heat transfer simulation where convective, radiative and conductive affects are considered concurrently. Back in the day much talk was had about…read more
CFD – Colourful Friday Distractions
April 8th, 2013
By way of an apology for the more verbose blogs I’ve been issuing recently I’d like to present you with a blog that serves no other purpose than to show a pretty picture. CFD as…read more
Experiment vs. Simulation, Part 3: JESD51-14
February 22nd, 2013
The JESD51-14 standard was published in November 2010, prepared by the JEDEC JC-15 Committee on Thermal Characterization. It outlines a new process to measure what is the most common IC package thermal metric, Theta_jc. This…read more
Adaptable Concurrent CFD Simulation Software Provides Ease-of-Use
February 11th, 2013
Mentor Graphics Corporation has announced the newest version of the FloEFD concurrent computational fluid dynamics (CFD) simulation software. According to the company, the new software version provides a “significant workflow process improvement, including automated geometry…read more
Experiment vs. Simulation, Part 1: Them and Us.
January 18th, 2013
Before you sell it, or commission it, you want to be sure that it works. Monies have been spent on getting things this far, some of it on you via your overhead and your expansive…read more
A Little Goes A Long Way (But A Lot Doesn’t Go Much Further)
May 3rd, 2012
It has been almost 3 years since I started this blog and I hope you’ve found it as interesting as I have cathartic. Although I’m not as yet bereft of topic ideas, I thought this…read more
Simulation Software So Simple Even Teenagers Can Use It
April 4th, 2012
The UK government has a policy for all year 10 or year 11 students to undertake a week’s work experience. Last week we welcomed a 15 year old student to the Mentor office where the…read more
3D Fluid-Flow Analysis Software
March 26th, 2012
TriStar increases its expertise in the CAD design market by taking part in the area of pre-physical prototype production. The Mentor Graphics® FloEFD™ product is a full-feature 3D fluid-flow analysis package that enables engineers to…read more
Data Center Technology Controls Temp by Moving Software Workloads
March 9th, 2012
Facebook is exploring a technology that controls temperatures in the data center by automatically moving software workloads among servers according to the air pressure on either side of each machine. The system uses a load…read more
Bottlenecks and Interface Materials; Part 3 – Relieving Thermal Bottlenecks Reduce Temperatures
February 10th, 2012
As with all good inventions, you quickly wonder how on earth you could have done without them before. Relieving thermal bottlenecks reduce temperatures; it’s so blindingly obvious. Now that we have the ability to visualise…read more
