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 , PCB Termal, Heavy Copper PCB) e kind of board PCB bi maddî bingehê metal li şûna cam Kiras FR4, FR3 an others.There yek yekalî nameşe, qat bi yekalî nameşe, û multilayer e pêşewarî. Li piraniya 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 tê bikaranîn ku li şûna kevneşop FR4 an CEM3 PCBs ji ber ku mirov bikaribe bi awayekî efektîv Disa germ û dûr ji hemû pêkhateyên. Ev ji aliyê bikaranîna perdeyeke dielectric thermally parê bidestxistin.
The dielectric prepreg provides transfer germa baş ji foil û pêkhateyên bi plakaya bingehîn, tevî ku tecrîda elektrîkê baş. The bafûn base yan jî lewha sifir dide substrate yekitîya mekanîk single-cûr'e, û parvekirina û transferê germiya ji bo germahî kirîger, bi heybet surface an rasterast bi hewa ambient.
Metal feature Core PCB:
- tedawiya bitesîr yên wek termal li design circuit PCB
- Agirê xebatê, zêdekirina de piraniya hêz û îtîbar, berfirehkirina jiyana ji berhemên
- Rêçên biçûk, hardware û civîn kêmtir mesrefên
- Replace nazik substrates seramîk PCB bi domdarîya mekanîk baştir
