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, težka baker PCB) je vrsta PCB plošče s kovinsko osnovni material namesto tkane steklene FR4, FR3 ali others.There je enostranski, dvostranski in večslojna krovu. Najbolj od 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 uporablja za zamenjavo tradicionalnih FR4 ali CEM3 PCB zaradi sposobnosti za učinkovito odvajanje toplote stran od komponent. To se doseže s pomočjo toplotno prevodne dielektrične plasti.
Prepreg dielektrično zagotavlja odlično prenos toplote iz folije in komponent glede na osnovni plošči, medtem ko vzdržujemo odlične električno izolacijo. Osnova aluminij ali baker ploščo daje enostranski substrat mehansko integriteto in distribuira in prenaša toploto toplotnega izmenjevalnika, vgradne površine ali neposredno v okoliški zrak.
Metal Core PCB funkcija:
- Učinkovito zdravljenje toplotne difuzije v oblikovanju PCB vezje
- Zmanjšanje delovno temperaturo, poveča gostoto moči in zanesljivosti, podaljša življenjsko dobo izdelka
- Manjši odtis, nižji stroški strojne opreme in montažo
- Zamenjajte krhko keramičnih substratov PCB z boljšo mehansko vzdržljivost
