Basking in the Light
The first time I came to London I was 5 years old.I'm pretty sure my parents dragged me to all the usual touristy places but I only remember disjointed fragments.Feeding ducks in Hyde Park.Sitting on the jump seat in a black cab.Holding on to my dad with one hand and holding on for dear life to my new bestie,a rather large light-brown teddy bear,while standing outside Hamleys.Come to think of …Read More

Why Not Just Shove a Heatsink on Top of it?Part 3: Pads,Vias and Undersinking
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
Why Not Just Shove a Heatsink on Top of it?Part 2: Heat Flow Budgets
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

Why Not Just Shove a Heatsink on Top of it?Part 1
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
What!All that just for that?The bonkers world of CPU cooling.
My colleague Ed and I were marvelling the other day at the CPU cooling unit from one of our 金宝搏娱乐城training desktop PCs undergoing a repair."What,all that just for that!?".The CPU itself was but a small square wafer compared to the behemoth that was the ducted fan and heatsink with integral heatpipes mounted on top of it.Whereas transistor sizes are measured in nanometres cooling systems can …Read More

PC Overclocking and Aftermarket Modding.Part 1 - When Colour Matters.
Automotive aftermarket modification has both mass appeal and a multi-million dollar turnover.Neon underbody lighting,enhanced radiator systems,aero-dynamic side skirts and hood scoops are but some of the ways in which you can part with your hard earned cash for that unbeatable feeling of looking sideways at the person in the car next to you as you narrow your eyes and nod your head slowly,marvelling …Read More

'Heat Trees' - taking a leaf out of natures book
Heatsinks aren't a novel energy efficient type of washing bowl,they are parts that are placed on high powered IC packages to help remove the heat more effectively and thus lower the operating temperature of the package which in turn increases reliability,can improve performance etc. etc.Such approaches are observed in nature,from Elephants ears to the low sun apparent surface area of homo erectus.…Read More
FloTHERM and its new XML neutral file format
We have recently published a new xml schema and associated xml reader for FloTHERM that offers some exciting new possibilities.Unlicensed and freely available it's well worth checking out.Introducing my first guest blogger,my colleague Byron Blackmore explains more…Byron is also a product manager for the electronics cooling line of business in the mechanical analysis division based in Canada.…Read More
Where do you fit in??
I think you can learn a lot by doing competitive benchmarking — the act of comparing yourself with your competitors along a certain set of criteria.It can highlight your strengths and weaknesses and it may even help you uncover new opportunities. While you may already be familiar with the concept as it applies to manufactured goods,I'm not sure how many people consider looking at what their competitors …Read More

The Lights...they're so beautiful
For some reason,the powers that be have decided to do roadworks on every major road leading out of my area of London.That means traffic has been diverted to two minor roads.Fair enough as the leaking Victorian water pipes need to be replaced.But what I don't understand is whythey all have to be done at the same time andthe same exact section of the A4 that was dug up for the entire length …Read More
