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 , mafana PCB, Heavy Varahina PCB) dia karazana biraom-PCB amin'ny fitaovana vy fototra fa tsy fitaratra FR4 mpanenona, FR3 na dia mpitovo others.There misy rindrina, misy rindrina avo roa heny, ary ny multilayer board. Ny ankamaroan ' 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 no ampiasaina mba hanoloana FR4 nentim-paharazana na CEM3 PCBs noho ny fahafahana mahomby nisinda hafanana miala ny singa. Izany no hanatontosana izany dia amin'ny fampiasana ny thermally conductive dielectric sosona.

Ny prepreg dielectric manome hafanana tsara famindrana avy amin'ny foil sy ny singa amin'ny tena ratsy lovia, raha tsara foana herinaratra fitokana-monina. Ny tavin-drano varahina aluminium na takela manome ny tokan-tena-misy rindrina substrate milina tsy mivadika, ary mizara ary famindrana ny hafanana ny hafanana hilatsaka, nitombo ambonin'ny na mivantana ny Ambient rivotra.

Metal Core PCB endri-javatra:

• Fahaiza-fitsaboana ny mafana diffusion amin'ny faritra PCB famolavolana
• Mampihena ny fandidiana mari-pana, hampitombo ny hery sy ny hakitroky azo antoka, hanitatra ny fiainana ny vokatra
• Dian-tongotra kely, ambany fitaovana sy ny vola lany fivoriana
• Soloy ny marefo tanimanga substrates PCB amin'ny milina tsara kokoa mateza
