Metal Core printed circuit boards, shortened to LED lighting PCB, or thermal management boards are printed circuit boards designed with a base metal core employed to disperse heat from the parts of the board, effectively lowering the core temperature of high heat applications. They are used when conventional fan-cooling techniques are insufficient for cooling the full system.
Most often seen in LED applications, MCPCBs will have a core of one of many following materials:
– aluminum (aluminum core PCB)
– copper (copper core PCB)
– a mixture of special alloys
With the most frequent of your three in the list above being aluminum core boards.
Metal core printed circuit boards transfer heat often (around 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 are 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/electric motor control applications
– Photovoltaic Applications
The LED light PCB generate a lot of warmth. Throughout the metal core’s dielectric polymer layer using a high thermal conductivity, the application overall carries a lower thermal resistance.
Other applications which are becoming increasingly more essential for metal core boards are solar panels and motion control applications.
As solar technology harnessing becomes more and more crucial in everyday applications like electric cars and solar panel roofs, the high temperature trapped within them increases. Likewise, with dexbpky11 motion control applications, large amounts of processing and friction are created to make the dynamics of the movement of the advanced technology robots.
In common computer applications today, LEDs and LED indicator lighting is often used. The sunshine and also heat produced by LED PCB has increased the core temperature of applications significantly, making the requirement for thermal management increasingly important. Metal core boards are most often located in LED applications and likewise in LED-heavy computing devices situations.
