Metel PCB Craidd

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,Metel PCB Craidd be widely used.

Metal core printed circuit board PCB (you aslo can call it MCPCB , PCB Thermol, Trwm Copr PCB) yn fath o PCB bwrdd gyda deunydd sylfaen metel yn lle gwydr gwehyddu FR4, FR3 neu rai eraill yn un ochr, dwy ochr, a multilayer bwrdd. Y mwyaf o 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.

Metel PCB Craidd yn cael ei ddefnyddio i gymryd lle FR4 neu CEM3 PCBs draddodiadol oherwydd y gallu i chwalu gwres effeithlon i ffwrdd o'r cydrannau. Cyflawnir hyn drwy ddefnyddio haen deuelectrig thermol dargludol.

Mae'r dielectric prepreg darparu trosglwyddo gwres ardderchog gan y ffoil a chydrannau i'r plât sylfaen, tra'n cynnal ynysu trydanol ardderchog. Mae'r alwminiwm sylfaen neu blât copr yn rhoi swbstrad cywirdeb mecanyddol un ochr, ac yn dosbarthu ac yn trosglwyddo'r gwres i sinc gwres, mowntio wyneb neu yn uniongyrchol i'r aer amgylchynol.

Metel nodwedd PCB Craidd:

• triniaeth effeithiol o drylediad thermol mewn dylunio cylched PCB
• Lleihau tymheredd gweithredu, cynyddu dwysedd pŵer a dibynadwyedd, ymestyn oes y cynnyrch
• ôl-troed llai, costau caledwedd a cynulliad is
• Amnewid y swbstradau ceramig bregus PCB gyda gwell gwydnwch mecanyddol
