Company Confidential Copyright 2014Slide #Intro Tom Gregory 6SigmaET Product Specialist

In this workshop I will be discussing how you can reduce you time to market with advanced thermal modelling techniques.

I will be happy to answer any questions at the end of the presentation. 1

Why is Thermal Design Critical?

The thermal design of equipment has an impact on the:

PerformanceReliabilitySafety

Can you afford to make a mistake with thermal design?

Overheating IT equipment caused Outlook and Hotmail shutdown March 2013Xbox 360 thermal failure cost Microsoft $1 billionFord Hybrid cars Overheating electronics led to recallSony phone Overheating Issues - Unresponsive Touch Screen

Company Confidential Copyright 2014Slide #Thermal design is often an after thought. A bad thermal design can have a huge impact on the final quality of the equipment.

Performance: Functional operation of device, Efficiency minimisation of leakage currentReliability: Temperature dependency of failuresSafety: Flammability, user safety, user comfort

Xbox High Failure rate. Widely believed to be caused by the device overheating - Reliability

Hotmail Overheating data center caused 18 hour shutdown - Performance

MAC Safety User Comfort. The component may be within specification but it does not feel ok.

Bosch Dishwasher Caused house fire. Over 600,000 recalled. - Safety4

Cost of Fixing a Design IssueBased on: Error Cost Escalation Through the Project Life Cycle NASA Johnson Space Center

Company Confidential Copyright 2014Slide #I am sure you have all seen this graph before. It is important that any design issue are found early. Any mistake found late in the design cycle are expensive to fix.

Bosch and Xbox Recall very expensive

Cost of a design issue through the product lifecycle

Many engineers find thermal issues at the prototype stage5

What is the Impact of a Thermal Design Issue?Cost

PCB redesignEnclosure redesignAdditional components heatsinks, fans

TimePart redesignMissed project deadlinesMarket opportunity missed

Company Confidential Copyright 2014Slide #Can impact the entire design

Cost could be huge

Weight Bigger Heatsink

Noise Faster fan

Increased cost High spec components (military standard, heatsinks)

Reduced equipment functionality Reduce CPU speed, removal of functions. 6

How can Thermal Simulation Help?What is thermal simulation of electronics?Prediction of:TemperatureAirflow Using computational fluid dynamics (CFD)

How can thermal simulation help you make better engineering decisions?

Visual representation of the temperature and airflow to quickly highlight issuesIdentify overheating components before a prototype is createdExperiment with solutions without having to prototype

Company Confidential Copyright 2014Slide #Airflow is invisible.

Temperature in electronic equipment is very difficult to measure and often not very accurate.

Avoid time and money prototyping a cooling system that will not work. 7

Company Confidential Copyright 2014Slide #Thermal simulation should be performed early and throughout the design cycle.

You dont need a full detailed design before doing simulation. 9

Company Confidential Copyright 2014Slide #What are the Benefits of using Thermal Simulation? Save Money, Save Time!

Perform thermal design of parts and equipment early in the design cycle

Verify thermal design before manufacture

Enables innovation

Company Confidential Copyright 2014Slide #The cost goes up the later in the design cycle the problem is found.

Once parts are manufactured the cost of modification is very high

Cost Optimize design remove unnecessary heatsink, fans etc. 11
