Chuma 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,Chuma Core PCB be widely used.
Metal core printed circuit board PCB (you aslo can call it MCPCB , Thermal PCB, Heavy Copper PCB) ni aina ya PCB bodi na nyenzo chuma msingi badala ya kusuka kioo FR4, FR3 au others.There ni moja upande mmoja, mbili upande mmoja, na multilayer bodi. Zaidi ya 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.
Chuma Core PCB ni kutumika badala ya jadi FR4 au CEM3 PCB kwa sababu ya uwezo wa ufanisi kupelekea joto mbali na vipengele. Hii ni mafanikio kwa kutumia thermally conductive safu dielectric.
prepreg dielectric hutoa bora joto uhamisho kutoka foil na sehemu ya sahani msingi, na kudumisha bora umeme kutengwa. msingi alumini au sahani shaba anatoa moja kuwa upande mmoja substrate mitambo uadilifu, na inasambaza na uhamisho joto joto kuzama, mounting uso au moja kwa moja kwa hewa iliyoko.
Chuma Core PCB kipengele:
- tiba nzuri ya usambazaji mafuta katika PCB mzunguko kubuni
- Kupunguza joto uendeshaji, kuongeza nguvu wiani na kuegemea, kuendeleza maisha ya bidhaa
- Ndogo footprint, chini ya vifaa na mkutano gharama
- Kuchukua nafasi ya tete kauri substrates PCB na bora uimara wa mitambo
