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 , Ang init nga PCB, Bug-at nga Copper PCB) mao ang matang sa PCB board sa metal nga base sa materyal nga inay sa maghahabol bildo FR4, FR3 o others.There mao ang single sided, double sided, ug multilayer board. Ang kadaghanan 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 gigamit sa pag-ilis sa tradisyonal nga FR4 o CEM3 PCB tungod sa abilidad sa pagkamasangputon mawala kainit gikan sa mga sangkap. Kini makab-ot pinaagi sa paggamit sa usa ka thermally conductive dielectric layer.

Ang prepreg dielectric naghatag og maayo kaayo nga pagbalhin sa kainit gikan sa foil ug mga sangkap sa base plate, samtang pagmintinar maayo kaayo nga electrical inusara. Ang base aluminum o tumbaga plate naghatag sa single-sided substrate mekanikal nga integridad, ug-apod-apod ug balhin sa kainit sa usa ka kainit unlod, nagdaghan, nagdamo nawong o direkta ngadto sa mga naglibot nga hangin.

Metal Core PCB bahin:

• Epektibo nga pagtambal sa mga sa kainit pagkatay, pagkanap sa PCB sa sirkito design
• Pagpakunhod operating temperatura, sa pagdugang sa gahum Densidad ug kasaligan, extend sa kinabuhi sa produkto
• Ang mas gagmayng tunob, ubos nga hardware ug katilingban gasto
• Mopuli sa huyang ceramic substrates PCB uban sa mas maayo nga mekanikal nga kalig-on

PCB aplikasyon Metal Core:

• Suga: LED kahayag mao ang pinakadako nga user sa Aluminium PCB
