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 , PCB obushushu, Heavy Copper PCB) luhlobo ibhodi PCB imathiriyeli endaweni zeglasi yokwaluka FR4, FR3 okanye others.There isiseko but is olunye uhlangothi lwayo, amacala amabini, nokuba multilayer ebhodini. Eyona kakhulu 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 lisetyenziswa indawo bemveli FR4 okanye CEM3 PCBs ngenxa ubuchule uthothe eyiyo ubushushu kude amacandelo. Oku kuphunyezwa ngokusebenzisa umaleko thermally conductive Heating.

Le Heating prepreg inika transfer ubushushu lexinene eka ngefoyile ye kunye namacandelo ukuba nembasa isiseko, lo gama kugcinwe yodwa zombane obalaseleyo. I-aluminiyamu Isiseko okanye imbasa yobhedu unika zeendawana ingqibelelo mechanical bahlangene olunye-, ize isasaze kwaye lidlulise nobushushu isinki ubushushu, obuninzi umphezulu okanye ngqo emoyeni voice.

Metal Core PCB phawu:

• unyango olusebenzayo of kwe- thermal kuyilo circuit PCB
• Nciphisa ubushushu yokusebenza, ukwandisa ingxinano amandla nokuthembeka, wandise ubomi lemveliso
• imithombo ezincinane, hardware kunye nebandla iindleko ezisezantsi
• Buyisela ezonakala substrates yodongwe PCB kunye ihlala engcono mechanical

Metal Core izicelo PCB:

• Izibane: LED Ukukhanya umsebenzisi enkulu Aluminium PCB
• imodyuli Power: Converters Power, Inverters, eqinileyo baphinde karhulumente, iibhulorho amandla rectifier
• Power ubonelelo: isenza i alawulayo, DC / AC lokuguqulela, SW Regulator
• Unxibelelwano izixhobo zombane: oluvela rhoqo ngombhobho, izixhobo zombane filter, iziphaluka samaza
• izixhobo Audio: igalelo, yokukhulisa imveliso, yokukhulisa elungeleleneyo, yokukhulisa odiyo, preamplifiers, yokukhulisa amandla
• iibhodi CPU, diski floppy drives, izixhobo unikezelo lwamandla: Computer
• Office izixhobo esizisebenzelayo: motor drives ...
• imodyuli Power: Inverters, oqinileyo baphinde karhulumente, iibhulorho amandla rectifier
• Car: Regulator Electronic, ucinezelo, izilawuli amandla ...
