Metal Core printed circuit boards, shortened to LED PCB, or thermal management boards are printed circuit boards built with basics metal core accustomed to disperse heat through the parts of the board, effectively decreasing the core temperature of high heat applications. They are used when conventional fan-cooling techniques are insufficient for cooling the full system.
Most often found in LED applications, MCPCBs may have a core of one of several following materials:
– aluminum (aluminum core PCB)
– copper (copper core PCB)
– a combination of special alloys
With the most typical of your three in the above list being aluminum core boards.
Metal core printed circuit boards transfer heat often times (approximately 8 or 9 times) faster than FR4 boards. MCPCB laminates scatter and eliminate heat, keeping heat generating components cooler which leads to increased performance and life of the applications.
Common LED applications where metal core boards can be found:
– Back light unit applications
– Street safety applications (streetlights, lighting, etc.)
– General lighting applications
– System automotive LED applications
– Power converters: telecom, industrial, high voltage regulator, power supplies
– Hybrid/motor unit control applications
– Photovoltaic Applications
The LED light PCB generate huge amounts of heat. With the metal core’s dielectric polymer layer using a high thermal conductivity, the application overall includes a lower thermal resistance.
Other applications that happen to be becoming increasingly more important for metal core boards are solar energy panels and motion control applications.
As solar power harnessing becomes more and more crucial in everyday applications such as electric cars and solar power roofs, the heat trapped within them increases. Likewise, with dexbpky11 motion control applications, large amounts of processing and friction are created to create the dynamics from the movement of the advanced technology robots.
In common computer applications today, LEDs and LED indicator lighting is often used. Light and also heat made by LED PCB has increased the core temperature of applications significantly, making the requirement for thermal management increasingly important. Metal core boards are normally seen in LED applications and likewise in LED-heavy computing devices situations.
