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 , Termisk PCB, Heavy Copper PCB) er slags PCB bord med metal basismateriale i stedet for vævet glas FR4, FR3 eller others.There er enkeltsidet, dobbeltsidet, og flerlags bestyrelse. De fleste af 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 anvendes til at erstatte traditionelle FR4 eller CEM3 PCB grund af evnen til effektivt sprede varmen væk fra komponenterne. Dette opnås ved anvendelse af en termisk ledende dielektrisk lag.

Prepreg dielektriske giver fremragende varmeoverføring fra folien og komponenter til bundpladen, og samtidig opretholde fremragende elektrisk isolation. Basen aluminium eller kobber plade giver enkeltsidet substrat mekanisk integritet, og distribuerer og overfører varmen til et kølelegeme, monteringsfladen eller direkte til den omgivende luft.

Metal Core PCB-funktionen:

• Effektiv behandling af termisk diffusion i PCB kredsløb design
• Reducere driftstemperatur, øge effekttæthed og pålidelighed, forlænge levetiden af ​​produktet
• Mindre fodaftryk, lavere hardware og monteringsomkostninger
• Erstatte den skrøbelige keramiske substrater PCB med bedre mekanisk holdbarhed
