Happy 25th FloTHERM

Posted by Nazita Saye

Nazita Saye In this day and age where products come and go in a flash it is a great honor to be involved with something that has successfully passed several major milestones. Twenty-five years ago, Flomerics opened its doors and FloTHERM moved from being a glimmer in the minds of Drs. Rosten and Thatchell to something real. The team of idealists had very definite thoughts when they sat down to create FloTHERM. … Read More

Thanksgiving Turkey Analysis in FloEFD

Posted by Travis Mikjaniec

Travis Mikjaniec Hello Everyone It’s been a while since my last blog as it’s been a very busy year.  One blog topic I’ve been wanting to do for a while is look into roasting turkeys.  Let me explain.  My wife is not very good at cooking American food.  Well I likely don’t need American in that sentence.  So when we moved into our house, and started our family, one of the issues that I needed … Read More

Future Phone

Posted by Nazita Saye

Nazita Saye You all know how gadget-mad I am, right? Well guess what’s got my senses buzzing today? A mobile phone that you can build yourself from various components … something akin to a Lego phone and it’s called the Phoneblok. A Dutch designer, Dave Hakkens, came up with the idea after he wanted to replace a single broken component in his mobile phone. When he was told that he couldn’t just replace the broken … Read More

Design Based on Assumptions

Posted by Nazita Saye

Nazita Saye I recently read an article about the Soviet space shuttle program which I found absolutely fascinating. We all know about the rivalry between the Americans and the Russians during the cold war so nothing new there. But what I found fascinating was how the Russians made a series of assumptions about the American space shuttle program based on information gleamed from various sources. And unfortunately, … Read More

Light My Way

Posted by Nazita Saye

Nazita Saye My last blog post about trash cans on London streets turned out to be quite controversial. It wasn’t my blog post that caused a furor but I guess a few other folks in London were on the same wavelength as me when they came across these bins. In case you missed my last post, here’s a quick summary. A company in England has tricked out a whole network of trash cans in London with LED displays that serve … Read More

Brave New World?

Posted by Nazita Saye

Nazita Saye I live and work in the burbs but I go into London every week. I usually hang out where my friends live. But from time to time work takes me to the square mile. The square mile is where most of the financial services industry is based in London. On days where I find myself in that neighborhood I feel like a country bumpkin. You see I tend to walk just a nudge slower than the masses – I’m used to … Read More

Robin Bornoff An appreciation of heat flow paths is a pre-requisite for good thermal design. If you attempt to augment heat flow where there is none then your expectations are as futile as your design skills. The real value of simulation for me is that it enables an insight into the behaviour of a proposed design (this is true for simulation of any design and any behaviour). Once you understand the true physics of … Read More

Posted by Nazita Saye

Nazita Saye I got my love of cars from my dad. He’d get bored with his car so every year he’d bring home a new one.  It would be done without fuss or ceremony. One night he’d simply return home from the office in a new car. To humor my dad, my mom would usher the kids out to the car so we could ooh and aah for a few minutes and then we’d be herded back inside. Being the cheeky baby, I’d always sneak out later in … Read More

Robin Bornoff 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 a product concept, beyond that it can be used to understand *why* the thermal behaviour is what it is. In Part 1 we saw that the BGA type package benefited from an 81% drop of junction temperature … Read More

Robin Bornoff 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 a heatsink passing to the air over a much larger area than it would otherwise do. Air can then do its magic, whisking the heat away thus keeping the electronics that … Read More

Hot Off the Press

Posted by Nazita Saye

Nazita Saye I don’t know about you but I read. A lot… It’s almost as if I’ve got an unquenchable thirst for information. It all started when I was 6 during a school break. I was bored and pestered my mom one too many times. In those pre-Nintendo days, she unceremoniously dumped me in my father’s study and told me to read a book.  I couldn’t reach most of the books on the shelves but my oldest sister had left her … Read More

Robin Bornoff 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 design information inside either. Pros and cons of detailed models I covered a few years ago in this blog. Packaged ICs are complex, constructed of many parts, with many different material … Read More

CFD - Colourful Friday Distractions

Posted by Robin Bornoff

Robin Bornoff 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 an acronym has quite a few different interpretations. Contracts for Difference if you’re into your financials. Colour For Directors if you’re in marketing. Cheats, Frauds and Deceivers if you’re … Read More

Robin Bornoff 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 turbulence modelling, convective discretisation schemes and linear equation solvers, all typical CFD subjects but somewhat out of place in the context of what became the … Read More

Some Like it Hotter

Nazita Saye You all know what a chatterbox I can be when I’m excited about something. So believe you me when I say the past few months have been excruciatingly hard for me. I’ve been sitting on some pretty big news and I’ve been itching to tell the world all about it.  Now that the cat is officially out of the bag, there’s no holding me back… FloTHERM XT as the enabling technology in the EDA/MDA design flow. The … Read More
