Gabatarwar MCPCB

MCPCB shine taƙaitaccen bayanin Metal core PCBS, gami da PCB na tushen aluminum, PCB tushen jan karfe da PCB tushen ƙarfe.

Aluminum tushen allo shine nau'in gama gari.A tushe abu kunshi wani aluminum core, misali FR4 da kuma jan karfe.Yana da nau'i mai rufi na thermal wanda ke watsar da zafi a cikin ingantacciyar hanya yayin sanyaya abubuwa.A halin yanzu, PCB Based Aluminum ana ɗaukarsa azaman mafita ga babban iko.Aluminum tushen allon iya maye gurbin frangible yumbu tushen jirgin, da aluminum samar da ƙarfi da karko ga samfurin da yumbu tushe ba zai iya.

Copper substrate yana daya daga cikin mafi tsadan karfen karfe, kuma yanayin zafinsa ya ninka na aluminum substrates da baƙin ƙarfe sau da yawa.Ya dace da mafi girma yadda ya kamata zafi watsar da high mita da'irori, sassa a cikin yankuna tare da babban bambanci a high da ƙananan zafin jiki da daidaitattun kayan sadarwa.

Thermal rufi Layer na daya daga cikin core sassa na jan karfe substrate, don haka kauri na tagulla tsare ne mafi yawa 35 m-280 m, wanda zai iya cimma wani karfi halin yanzu-daukar iya aiki.Idan aka kwatanta da aluminum substrate, jan karfe substrate iya cimma mafi zafi watsawa sakamako, don tabbatar da kwanciyar hankali na samfurin.

Tsarin Aluminum PCB

Layin Copper Layer

An haɓaka Layer na jan ƙarfe na kewaye kuma an tsara shi don samar da da'irar da'irar, ƙirar aluminum na iya ɗaukar mafi girma na halin yanzu fiye da FR-4 mai kauri ɗaya da faɗin alama iri ɗaya.

Insulating Layer

Ƙaƙƙarfan rufi shine ainihin fasaha na aluminum substrate, wanda ya fi dacewa da ayyuka na rufi da zafi.Ƙaƙƙarfan madaidaicin aluminum shine mafi girman shingen thermal a cikin tsarin tsarin wutar lantarki.Mafi kyawun ingancin thermal conductivity na insulating Layer, da mafi inganci shi ne don yada zafi da aka haifar yayin aikin na'urar, kuma rage zafin na'urar.

Metal substrate

Wani irin karfe za mu zaba a matsayin insulating karfe substrate?

Muna bukatar mu yi la'akari da thermal fadada coefficient, thermal watsin, ƙarfi, taurin, nauyi, surface jihar da kuma kudin na karfe substrate.

A al'ada, aluminum yana da rahusa fiye da jan karfe.Samfuran kayan aluminum sune 6061, 5052, 1060 da sauransu.Idan akwai ƙarin buƙatu don haɓakar thermal, kayan aikin injiniya, kayan lantarki da sauran kaddarorin na musamman, faranti na jan karfe, faranti na bakin karfe, faranti na ƙarfe da faranti na silicon kuma ana iya amfani da su.
