Metal Prìomh 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 Prìomh PCB be widely used.

Metal core printed circuit board PCB (you aslo can call it MCPCB , ìomhaigheach tearmach PCB, Trom Copper PCB) 'S e seòrsa de PCB bòrd meatailt ionad stuth an àite fìghte glainne FR4, FR3 no others.There' S e aon taobhach, dà thaobhach, agus multilayer bòrd. Tha a 'chuid as motha de 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 Prìomh PCB air a chleachdadh airson an àite traidiseanta FR4 no CEM3 PCBs sgàth an comas èifeachdach dissipate teas air falbh bho na co-phàirtean. Tha seo ga choileanadh le bhith a 'cleachdadh thermally conductive dielectric filleadh.

Tha prepreg dielectric a 'toirt seachad sàr-mhath gluasad teas bho foil agus co-phàirtean a' bhonn truinnsear, fhad 'sa bha a' cumail suas sàr-dealain iomallachd. Tha an ionad almain no umha truinnsear a 'toirt an aon-taobhach fo-fhilleadh meacanaigeach ionracas, agus a' sgaoileadh agus a 'tar-aiseag an teas a teas-sinc, a' cur air uachdar no dìreach ris an Ambient adhar.

Metal Prìomh PCB feart:

• Tearmach èifeachdach a leigheas ann an sgaoileadh PCB cuairt dealbhadh
• Lùghdaich obrachaidh Teòthachd, a 'meudachadh cumhachd dùmhlachd agus earbsachd, leudachadh air a' bheatha aig bathar
• Nas lugha lorg-coise, ìsle bathar-cruaidh is Seanadh cosgaisean
• Cuir an àite an cugallach ceramic mònach PCB le nas fheàrr meacanaigeach fàgail
