Inti Logam 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,Inti Logam PCB be widely used.

Metal core printed circuit board PCB (you aslo can call it MCPCB , PCB Thermal, Heavy tembaga PCB) adalah jenis papan PCB dengan bahan dasar logam bukan kaca tenun FR4, FR3 atau orang lain.Ada satu sisi, dua sisi, dan multilayer naik. Sebagian 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.

Inti Logam PCB digunakan untuk menggantikan tradisional FR4 atau CEM3 PCB karena kemampuan untuk secara efisien mengusir panas dari komponen. Hal ini dicapai dengan menggunakan lapisan dielektrik konduktif termal.

The prepreg dielectric menyediakan transfer panas yang sangat baik dari foil dan komponen untuk pelat dasar, sambil mempertahankan isolasi listrik yang baik. Dasar aluminium atau pelat tembaga memberikan substrat integritas mekanik satu sisi, dan mendistribusikan dan transfer panas ke heat sink, pemasangan permukaan atau langsung ke udara ambien.

Logam fitur inti PCB:

• Pengobatan yang efektif dari difusi termal di PCB desain sirkuit
• Mengurangi suhu operasi, meningkatkan densitas daya dan kehandalan, memperpanjang umur produk
• footprint yang lebih kecil, perangkat keras dan perakitan rendah biaya
• Menggantikan rapuh substrat keramik PCB dengan daya tahan mekanik yang lebih baik
