Metal Core PCB

With the increase of the LED chip size and polycrystalline LED the development of packaging design, LED the heat load are also redouble,in addition to this the heat dissipation capacity of plate material, its thermal stability of materials are also affect the LED products’ life.In short, high power LED products loading board material needs to have at the same time the characteristics of high heat dissipation and high heat resistance, so the packaging substrate material becomes the key factor, on the application of traditional LED heat dissipation substrate,Metal Core PCB be widely used.

Metal core printed circuit board PCB (you aslo can call it MCPCB , Thermal PCB, Malakas Copper PCB) ay uri ng PCB board na may metal base materyal sa halip na pinagtagpi glass FR4, FR3 o others.There ay solong kinakampihan, double sided, at multilayer board. Ang karamihan sa Metal Core PCB manufacturers are commonly used metal core material is aluminum, copper and alloy. Aluminum is the most frequently used among them due to its good heat transfer ability,dissipation ability and relatively cheaper costs than copper,even which may has a better performance,so it widely was accepted.copper although have better performance,but its cost more expensive,steel is more rigid than both aluminum and copper,it has normal steel and stainless steel,but its thermal conductivity is lower than others,simple speaking,aluminum material is the best choice,even considering from cost,rigidness and thermal conductivity.

There are single sided,two layer and multi-layer mcpcb,the Single sided metal core printed circuit board consists of a metal base (aluminum or copper alloy), dielectric layer, and copper conductor layer. The single layer MCPCB can be used with surface mount and chip & wire components. It provides much lower thermal resistance than FR4 PCB. And the metal core provides lower cost and allows much larger areas than ceramic substrates.

Metal Core PCB ay ginagamit upang palitan ang tradisyonal na FR4 o CEM3 PCBs dahil sa ang kakayahan upang mahusay na waldasin init ang layo mula sa mga bahagi. Ito ay nakamit sa pamamagitan ng paggamit ng isang thermally kondaktibo dielectric layer.

Ang prepreg dielectric ay nagbibigay ng mahusay na init transfer mula sa palara at mga bahagi sa base plate, habang pinapanatili ang mahusay na mga de-koryenteng paghihiwalay. Ang base aluminyo o tanso plato ay nagbibigay sa mga single-sided substrate makina integridad, at namamahagi at paglipat ng init sa isang init lababo, mount ibabaw o direkta sa ambient air.

Metal Core PCB tampok na ito:

• Ang mabisang paggamot ng mainit pagsasabog sa PCB circuit na disenyo
• Bawasan ang operating temperatura, dagdagan ang kapangyarihan density at pagiging maaasahan, pahabain ang buhay ng produkto
• Mas maliit footprint, mas mababang hardware at assembly mga gastos
• Palitan ang marupok ceramic substrates PCB na may mas mahusay na mechanical tibay
