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, Heavy Copper PCB) er eins konar PCB borð við málm grunnefnið í stað ofið gler FR4, Fr3 eða others.There er einn hliða, tvöfaldur hliða og fjöllaga borð. Sem mest úr 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 er notað til að skipta hefðbundnum FR4 eða CEM3 PCB vegna getu til duglegur dreifa hita frá efnisþátta. Þetta er gert með því að nota varmaleiðandi dielectric lag.
The prepreg dielectric gefur frábæra varmaflutning frá filmu og hluti til að grunnplötu, en viðhalda framúrskarandi electric einangrun. Grunnurinn ál eða kopar plata gefur einn-hliða undirlag óskertan, vélrænan stöðugleika, og dreifir og flytur varma í hita vaskur, fara upp yfirborð eða beint til andrúmslofti.
Metal Core PCB lögun:
