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 , Termalni PCB, teški bakra) je vrsta PCB ploča sa metalnom bazom materijala, umjesto od komada stakla FR4, FR3 ili others.There je jednostrani, dvostrani, i višeslojne odbora. Najveći broj 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 se koristi za zamjenu tradicionalnih FR4 ili CEM3 PCB zbog sposobnosti da efikasno trošiti topline od komponenti. To se postiže pomoću termički provodni dielektrična sloja.

U predimpregniranog dielektrična pruža odličnu prijenos topline iz folije i komponente osnovne ploče, zadržavajući odlična električna izolacija. U bazi bakrenih ili aluminijskih ploča daje jednostrano podloge mehanički integritet, i distribuira i prenosi toplinu na hladnjak, fiksiranje na ravnu površinu ili direktno na okolni vazduh.

Metal karakteristika Core PCB:

• Efikasan tretman toplinske difuzije u PCB dizajn kola
• Smanjite radna temperatura, povećanje gustoće snage i pouzdanosti, produžiti vijek trajanja proizvoda
• Manjim dimenzijama, niže hardver i montaže troškove
• Zamijenite krhka keramičke podloge PCB sa bolja mehanička izdržljivost
