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 Thermal, Heavy yethusi PCB) kuyinto uhlobo PCB ibhodi metal isizinda impahla esikhundleni Nokwelukiweyo ingilazi FR4, FR3 noma others.There engashadile emaceleni, kabili emaceleni, futhi multilayer ibhodi. I iningi 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 isetshenziswa esikhundleni bendabuko FR4 noma CEM3 PCB ngenxa ikhono kahle ukudamba ukushisa kude izingxenye. Lokhu kufezwa ngokusebenzisa ungqimba thermally conductive Kwe-dielectric Heating.

I Kwe-dielectric Heating prepreg inikeza kakhulu yokudlulisa ukushisa kusukela ucwecwe izingxenye plate isizinda, ngesikhathi esifanayo ulondoloze isimo esihle ngabodwa kagesi. Aluminiyamu isizinda noma plate zethusi unikeza olulodwa emaceleni substrate ubuqotho mechanical, futhi ihambisa futhi idlulisela ukushisa kuya echibini ukushisa, obandayo surface noma ngqo emoyeni kuma.

Metal Core PCB sici:

• ukuphathwa ngempumelelo okusheshayo ezishisayo e PCB design wesifunda
• Yehlisa izinga lokushisa lokusebenza, ukwandisa amandla ukuminyana futhi waba nokwethenjelwa, ukunweba ukuphila komkhiqizo
• lokungcolisa ezincane, ephansi hardware kanye inhlangano izindleko
• Buyisela ethambile substrates Ceramic PCB ne kangcono ukuqina mechanical

Metal Core PCB izicelo:

• Ukukhanyisa: LED Light kuyinto umsebenzisi enkulu Aluminium PCB
• Amandla mojuli: Amandla converters, inverters, okuqinile isimo udlulisela, amandla rectifier amabhuloho
• Amandla kagesi: ukushintsha Regulator, DC / AC lokuguqulela, SW Regulator
• Ukuxhumana zikagesi: ephezulu imvamisa amplifier, ukuhlunga zikagesi, Lidlulisela izifunda
• imishini lomsindo: okokufaka, okukhipha yokukhulisa umsindo, yokukhulisa umsindo olinganiselayo, alalelwayo yokukhulisa umsindo, preamplifiers, amandla yokukhulisa umsindo
• Ikhompyutha: CPU amabhodi, idrayivu oshayelayo disk, amadivayisi ugesi
• Ihhovisi imishini ezishintshayo: motor ngemoto ...
• Amandla mojuli: inverters, okuqinile isimo udlulisela, amandla rectifier amabhuloho
• Car: Umlawuli Electronic, ukuthungela, amandla abalawuli ...
