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, teške bakar PCB) je vrsta PCB ploču s metalnim osnovnog materijala umjesto tkane staklene FR4, ili FR3 others.There je jednostruki, dvostrani i višeslojni odbor. Većina 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 koriste kao zamjena za tradicionalne FR4 ili CEM3 PCB zbog sposobnosti da učinkovito trošiti topline od komponenti. To se postiže upotrebom dielektrične toplinski provodljivog sloja.

Prepreg dielektrik osigurava izvrsnu prijenos topline od folije i komponenata na osnovnu ploču, uz održavanje izvrsnu električnu izolaciju. Baza aluminija ili bakra daje jednostrano supstrata mehaničku cjelovitost i distribuira i prenosi toplinu na hladnjak, površine za montažu ili izravno na okolnom zraku.

Metal core PCB značajka:

• Učinkovito liječenje toplinske difuzije u dizajnu PCB krug
• Smanjiti radnu temperaturu, povećava gustoću snage i pouzdanosti, produžiti vijek trajanja proizvoda
• Manji otisak, niže hardvera i montaža troškovi
• Zamijenite krhku keramičke podloge PCB s boljim mehaničkim trajnost
