LED Heat sinking guide

9 12 2011

Without LEDs, companies such as Amphenol would be unable to offer the range of connectors and various other electronic components which they currently do.  

An LED is essentially a semiconductor light source. They are used as indicator lamps in a vast range of electronic devices and were first introduced in 1962.

When power LEDs first arrived onto the market, a number of lighting firms rushed out solid-state luminaries only to find them failing in service.

The fundamental problem was heat sinking. Manufacturers were used to filament bulbs that run hot and are cooled by radiation.

That may have been a while ago now. However, the danger of producing unreliable products still exists, particularly as manufacturing companies strive to keep costs down to a minimum.

How do heat sinks work?

The heat generated by complex devices and circuitry can often threaten the reliability of a product and, in some cases, tamper with the ability of a device to function correctly.

With this in mind, heat sinks have become an essential part of modern electronics manufacturing.  Several companies would simply be unable to produce high quality equipment without using this technique.

They are used to reduce and control the temperature of items such as microprocessors through sophisticated heat dissipation techniques. It is at times a complex, but necessary process.

They are basically made up of a small metal structure which includes flat surfaces to ensure good thermal contact with the components that need to be cooled.

A heat sink absorbs and dissipates heat from another object using thermal contact. They are used in a vast range of applications which could include anything that requires efficient and effective protection from heat.

Thermal management – An essential part of electronics

4 08 2011

One of the most important aspects of electronics is controlling the heat which is generated by the construction of complex devices and circuitry.

This heat can often threaten the reliability of a product, in some cases ensuring devices fail to function completely before they have been used at all.

Techniques for heat dissipation include the use of fans and heat sinks for air cooling, liquid cooling and computer cooling.

Within the electronics industry, they are used most frequently for the cooling of electronic devices. Complex circuitry and devices require protection from the extreme generation of heat, otherwise they cannot perform the tasks for which they were designed.

Heat sinks are often used while soldering circuit boards, helping to prevent excessive heat from damaging the complex electronic aspects.

For example, electrical components such as magnetic reed switches can malfunction if exposed to higher powered soldering irons. Some modern electronic devices can withstand high temperatures because of their specific design, but if there is a doubt over it then heat sinks are an essential tool.

The protection of intricate devices such as surface boards from extreme heat is a basic yet essential requirement within the electronics industry.

Electronic Thermal Management Industry Worth $8.6 Billion By 2015

12 01 2011

The global market for Electronic Thermal Management is forecast to reach US$8.6 billion by the year 2015, according to a new report into the industry.

Factors driving growth include developments in technology and a marked increase in the production of miniaturized microprocessors. The growing sophistication of mobile devices is also likely to impact market growth, too, according to the report Electronic Thermal Management – A Global Strategic Business Report by research group Global Industry Analysts.

Thanks to more complex needs of electrical components, thermal management has assumed an important role in product development and associated costs in bringing products to market. Thermal management for cooling such products requires the device design to be aligned in parallel form with the design of the electronic product. The techniques used in the thermal modules effectively predict the thermal behaviour of a product and helps in the electronic component designing at a great saving in cost for optimal thermal performance.

Today’s printed circuit boards (PCBs) need efficient thermal management solutions such as thermoelectric coolers and heat sinks to control rising power densities.

Electrical Thermal Management Solutions

The increase in the production of miniaturized microprocessors is putting considerable demand for electronic thermal management devices. The miniature size of the processor and the enhanced power levels generate high levels of heat.

Hardware products, such as heat sinks and thermoelectric coolers, as well as software for designing these products have been highlighted as particular areas where growth is likely to occur and demand for specific and unique thermal management solutions.

Demand for Thermal Management Set to Grow

19 11 2010

The electronic thermal management industry is set to grow in the coming years, as demand for electronic systems and micro-processors increases, a new US research paper finds.

The economic recession and the down-turn in end-use sectors such as automotive, computers, telecom, industrial/military, medical/office equipment, and consumer electronics did have a negative effect on the growth of the thermal management industry globally.

However, a new report from Global Industry Analysts suggests that developments in technology and  a marked increase in the production of miniaturized microprocessors, as well as the increased use of mobile devices are going to lead to a recovery and growth of the industry in the coming years.

Analysts predict that electronic thermal management devices are likely to increase in demand in the coming years for their effective use in PCs, telecommunication systems and servers.

Hardware products, such as heat sinks and thermoelectric coolers, as well as software for designing these products have been highlighted as particular areas where growth is likely to occur.

Why is Thermal Management so Important in the Electronics Industry?

Better design and more densely packed components as electronic systems become smaller and smaller means that power densities continue to rise unabated. As a result, miniature processors and greater power levels generate high levels of heat, which is why thermal management solutions are needed to maintain systems.  

Electronic thermal management devices perform this job and cool the electronic components and the system from excessive heat during operation.

Also, demand is likely to increase with system integrators and original equipment manufacturers (OEMs) integrating more components on PCBs. Nevertheless, market growth is likely to be restricted with the system-on-chip design complexities.
