Metal core PCBs kuma ana kiransa MCPCBs, wanda Layer Layer Layer tushe ne na karfe. Mafi yawan karafa na MCPCBs da ake amfani da su sune aluminum, jan karfe, da gami da karfe. PCBs na tushen Aluminum sune mafi tsada-tasiri; suna da kyakkyawan yanayin zafi da kuma iyawar thermal a ƙananan farashin. PCB na tushen jan ƙarfe yana aiki fiye da aluminium, amma farashin ya fi girma. PCBs na tushen ƙarfe sun fi kayan biyu na farko wahala, yayin da tare da ƙarancin ƙarancin zafi. Metal PCBs da aka sani da su m thermal dissipation.A cikin 'yan shekarun nan, LED masana'antu da aka sauri ci gaba, amma matsalar zafi dissipation ya dame aikace-aikace da kuma ci gaban LED, musamman high-ikon LED a fagen haske. Aikace-aikace na karfe substrate yana ba da sabuwar hanyar da za a magance zafin zafi na LED yadda ya kamata.

Domin karfe core tushe abu, akwai aluminum da kuma jan karfe tushe kayan. Aluminum substrate wani nau'in farantin karfe ne na tushen ƙarfe tare da kyakkyawan canjin zafi da aikin watsawa. Copper Substrate yana da mafi kyawun aiki fiye da aluminum, amma farashin sa ya fi tsada fiye da aluminum.

Abokan ciniki suna yin odar pcbs na aluminum sau da yawa, saboda farashin aluminum pcb ya fi tattalin arziki, ana amfani da su don hasken wuta na LED, na'urorin mitar sauti da kayan lantarki na sadarwa.

MCPCB mai sauƙi mai gefe guda ɗaya ya ƙunshi tushe na ƙarfe (yawanci aluminum, ko jan ƙarfe), Layer Dielectric (marasa gudanarwa), Layer Circuit Copper, abubuwan IC da abin rufe fuska.

Kyakkyawan zubar da zafi na karfe core PCBs yana sa su ƙasa da haɗari ga babban zafin jiki, wanda ke haifar da ƙarancin murdiya yayin jigilar sigina.

Fa'idodin da aka ambata a sama suna sa ƙarfe core PCBs mafita mafi kyau a aikace-aikace da yawa, kamar masu canza wuta, fitilu, photovoltaic, aikace-aikacen hasken baya, aikace-aikacen LED na motoci, kayan gida, da sauransu. PCB na tushen Aluminum shine mafi yawan nau'in PCBs na ƙarfe na yau da kullun don fa'idar farashin sa. Musamman a cikin m-state lighting, aluminum PCBs taimaka cimma mafi girma haske matakan da ƙasa da yawa na LED.

Kauri mai kauri na jan karfe na MCPCB na iya zama 1oz zuwa 10oz, kuma kauri daga cikin allunan yawanci shine 30mil zuwa 125mil. YMS yana ba da kowane nau'ikan PCBs na ƙarfe na ƙarfe, kuma kawai a tuntuɓe mu idan kuna buƙatar ƙaramin abu mai kauri ko sirara. YMS koyaushe za ta ci gaba da kiyaye iyawarmu da ka'idodin kayan aiki tare da saurin matakan ci gaba don samarwa abokan ciniki mafi kyawun sabis na samfur na PCB, ƙirƙira PCB, haɓaka kayan aikin.
