Metal Core printed circuit boards, shortened to PCB PCBA, or thermal management boards are printed circuit boards created with basics metal core accustomed to disperse heat from the components of the board, effectively decreasing the core temperature of high heat applications. They are utilised when conventional fan-cooling techniques are insufficient for cooling the complete system.
Mostly located in LED applications, MCPCBs can have a core of one of many following materials:
– aluminum (aluminum core PCB)
– copper (copper core PCB)
– an assortment of special alloys
With the most typical from the three listed above being aluminum core boards.
Metal core printed circuit boards transfer heat often times (as much as 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/electric motor control applications
– Photovoltaic Applications
The LED light PCB generate large amounts of heat. With the metal core’s dielectric polymer layer using a high thermal conductivity, the applying overall has a lower thermal resistance.
Other applications which are becoming increasingly more valuable for metal core boards are solar power panels and motion control applications.
As solar energy harnessing becomes increasingly more crucial in everyday applications such as electric cars and solar cell roofs, the warmth trapped within them increases. Likewise, with dexbpky11 motion control applications, considerable amounts of processing and friction are made to create the dynamics in the movement from the advanced technology robots.
In common computer applications today, LEDs and LED indicator lights are often used. The light and also heat developed by LED PCB has risen the core temperature of applications significantly, making the necessity for thermal management increasingly important. Metal core boards are generally seen in LED applications and likewise in LED-heavy computer hardware situations.
