METAL CORE PCB
Highleap Electronics inopa Metal Core PCBs (MCPCBs) yeanoshanda ekudziya kwekutonga mune yakakwirira-simba maapplication senge LED mwenje, mota, nezvimwe.
Chii chinonzi Metal Core PCB
A Metal Core PCB (MCPCB) inoshandisa simbi yesimbi, yakaita sealuminium kana mhangura, kunatsiridza kupisa kupisa. Kusiyana neyakajairwa FR4 mabhodhi, MCPCBs inobata yakakwirira simba density nekuda kwesimbi yakanyanya kupisa conductivity. Copper Core PCBs inopa kutonga kwepamusoro kwekupisa, nepo Aluminium Core PCBs inodhura-inoshanda uye inowanzoshandiswa mumashandisirwo akaita semwenje uye magetsi emagetsi. Iyo musimboti inoiswa insulated neceramic dielectric layers kudzivirira mashorts emagetsi uku uchiona kufambiswa kwekushisa kwakanaka.
Kuti uwane rumwe ruzivo nezvezvinhu zveMCPCB, shanyira Metal Core PCB Materials . Kuti udzidze zvakawanda nezve dhizaini yeMCPCB, tarisa Metal Core Circuit Board.
Chimiro cheMCPCB
Metal Core PCBs ine matatu akakosha akaturikidzana: simbi musimboti, dielectric layer, uye mhangura layer. Ichi chimiro chakasiyana chinogadzirisa kupisa kupisa, kuwedzera kushanda kwese uye kuvimbika kwemagetsi masisitimu.
Iyo simbi musimboti, kazhinji aruminiyamu kana mhangura, inozvirumbidza yakakwira yekupisa conductivity uye simba remuchina. Ichiita sechidzitiro chekupisa, inonyatso fambisa uye inoparadzira kupisa kubva kune zvikamu, kuchengetedza hutano hwakanaka hwekushanda uye kudzivirira kukanganisa kwekushisa.
Iyo dielectric layer, yakasungirirwa kusimbi yesimbi, inopa kuvharwa kwemagetsi uye kudziya kwekutonga zvinhu. Yakagadzirwa kubva kumidziyo ine yakakwidziridzwa yekupisa conductivity, inofambisa zvakanaka kutamisa kupisa kubva kuzvikamu kuenda kusimbi yesimbi. Iyo dielectric layer inovimbisa kunyangwe kugovera kwekupisa, kuderedza hotspots uye kushushikana kwekupisa.
Zvakanakira MCPCB
Metal Core PCBs (MCPCB) maficha anoita kuti ave akanakira simba repamusoro uye tembiricha yemagetsi ekushandisa:
Metal Core PCBs inopa kutonhora kwepamusoro, kuvimbika kwakagadziridzwa uye kurerutsa dhizaini yekupisa - ichivaita sarudzo yakanaka yemagetsi emagetsi e LED, mota dzemagetsi, magetsi ekushandura module, nezvimwe.
Nguva Itsva Mukupisa Kupisa, Highleap Yakafukidza! Yedu simbi musimboti PCBs, kuvhura chitsauko chitsva mukupisa manejimendi.

Marudzi Makuru eMetal Core PCBs
Kune marudzi matatu makuru eMetal Core PCBs (MCPCBs) zvichienderana nesarudzo yesimbi yepakati zvinhu:
Aluminium Core PCBs
MaMCPCB aya ane musimboti wearuminiyamu, zvichiita kuti ave akareruka, asingadhuri, uye anoshanda zvakanyanya mukupisa. MaPCB earuminiyamu anowanzo shandiswa muzvishandiso zvakaita semwenje ye LED, zvemagetsi zvemotokari, uye zvemagetsi zvemagetsi. MaPCB earuminiyamu anozivikanwa nekushanda kwawo kwakanaka, kunyanya muzvishandiso zvinonzwa kupisa.
Mhangura Core PCBs
MaPCB emhangura ane core yemhangura anopa kufambiswa kwekupisa kwakanaka, zvichiita kuti akwanise kushandiswa nesimba guru rinoda kupisa kwakawanda. MaPCB emhangura anowanzo shandiswa mumakombiyuta anoshanda zvakanyanya, kutaurirana, uye michina yeindasitiri.
Yakasanganiswa Metal Core PCBs
Mamwe ma MCPCB anoratidza simbi yakasanganiswa, kusanganisa zvakanakira simbi dzakasiyana. Semuenzaniso, simbi yakasanganiswa core inogona kusanganisira mhangura yemhangura yekuwedzera kupisa kupisa uye aruminiyamu layer yekudhura-inoshanda. Aya akasanganiswa simbi musimboti PCBs anopa chiyero pakati pekuita uye mutengo, ichipa kune chaiyo application zvinodiwa.
Aluminium PCB VS Copper base PCB
Aluminium base PCBs

Musiyano pakati pesimbi musimboti PCB uye FR4 PCB
Kufambisa kwekupisa: MCPCB ine musimboti wesimbi, ine mashandiro ari nani ekuparadza kupisa kupfuura FR4 PCB.
Hupenyu hwebasa: Nekuda kwekupiswa kuri nani, hupenyu hwebasa reMCPCB hunowanzo kureba kupfuura FR4 PCB.
Kudzivirira kweEMI: Chikamu chesimbi cheMCPCB chinogona kudzivirira kukanganiswa kwemagetsi, nehukuru hwakasimba hwekudzivirira kukanganiswa.
Kufambisa: Chinoumba simbi (kazhinji mhangura kana aruminiyamu) cheMCPCB chine kufambisa kwakanyanya.
Kuwanda kwemagetsi: MCPCB inogona kuita kuti dunhu rive rakatetepa uye mipata midiki yekutumira magetsi, saka huwandu hwemagetsi hwacho hwakakwira.
Simba remuchina: Bhodhi resimbi reMCPCB rinowanzova rakaoma uye rakasimba kupfuura substrate yeFR4.
Mutengo: Mutengo weMCPCB unowanzo kuve wakakwira kupfuura weFR4 PCB yakajairika.
Chiyero chekushandisa: MCPCB yakakodzera mashandisirwo anoda simba rakawanda, density yakakwira, kumhanya kwakakwirira uye kuvimbika kwakakwirira, senge maseva emhando yepamusoro uye michina yekuyedza yehunyanzvi. FR4 PCB inoshandiswa zvakanyanya mumidziyo yakasiyana-siyana yemagetsi.
Muchidimbu, MCPCBs inopa akati wandei mabhenefiti pamusoro peFR4 PCBs, kusanganisira yepamusoro kupisa dissipation, yakakwirira yekupisa conductivity, uye yakasimba EMI kudzivirira. Nekudaro, zvakakosha kuti uzive kuti MCPCBs inowanzouya nemutengo wakakwira. Kusarudzwa pakati pezviviri zvinoenderana nezvinodiwa zvehunyanzvi zvekushandisa.
Kusanetseka-pasina Kupisa Kupisa, Highleap Yakafukidza! Yedu simbi yepakati PCBs, sarudzo yakakwana yekudziya manejimendi.
Metal Core PCB Dhizaini Mirayiridzo
Thermal Management
Iyo yesimbi musimboti muMCPCB inopa yakanyanya conductive nzira yekupisa kupisa. Kuti uve nechokwadi chekufambisa kupisa kwakanaka, zvakakosha kuti ugadzire bhodhi neyakakwana yekupisa vias, thermal pads, uye heatsinks. The thermal vias inofanira kunge iri pedyo nepedyo kune zvinopisa-inogadzira zvikamu uye inofanira kuva yehukuru hwakakwana kupa yakaderera kupisa kwekudzivirira.
Kusarudzwa Kwezvinhu
Nekuchenjera sarudza simbi yepakati zvinhu kuti ugone kuita MCPCB. Aluminium inowanzoshandiswa kune yayo yakakwirira yekupisa conductivity, mutengo-unoshanda, uye huremu zvivakwa. Nekudaro, mhangura, ndarira, kana simbi isina tsvina inogona kutariswa zvichienderana nezvinodiwa zvekushandisa. Pamusoro pezvo, iyo dielectric zvinhu uye ukobvu hwemhangura zvinokanganisa kuita kwebhodhi rose.
Trace Width uye Spacing
Dhizaina yakakodzera hupamhi hwekutsvaga uye nzvimbo yekubata ikozvino kutakura kugona uye kuchengetedza chiratidzo chekuvimbika. Ita shuwa kuti trace wide inokwana kutakura inodiwa ikozvino pasina kuunza kupisa kwakanyanya. Kupatsanurana kwakaringana pakati pezvitevedzwa kunoderedza kukanganiswa kwechiratidzo uye crosstalk. Seta hudiki hwekutsvagisa hupamhi uye nzvimbo zvichienderana nekugadzira maitiro uye zvidikanwi zvekushandisa.
Component Placement
Kuiswa kwezvikamu paMCPCB kwakakosha kune ese ari maviri ekutonga kwekupisa uye kutendeseka kwechiratidzo. Zvikamu zvesimba repamusoro zvinofanirwa kuiswa padhuze nesimbi musimboti kuti uwedzere kupisa kupisa, nepo zvinhu zvinonzwisa tsitsi zvakaita seRF maseketi zvichifanirwa kuiswa kure nekupisa. The component density inofanira kuvandudzwa kuti ive nechokwadi chekushandisa zvakanaka kwebhodhi nzvimbo uye kudzivirira kukanganiswa kwechiratidzo.
Solder Mask
Iyo solder mask paMCPCBs inofanirwa kugadzirwa kuti ifambise kupisa kwekufambisa uku ichipa insulation pakati pematanho. Sarudza solder mask ine matte kupera, sezvo inopa yakagadziridzwa yekupisa conductivity. Ita shuwa kucheneswa kwakakodzera uye kuvharika kudzivirira solder bridging uye mapfupi maseketi. Iyo yakanyatsogadzirwa solder mask inowedzera kushanda uye kuvimbika.
Kufunga kwekupedzisira
Pamusoro peiyo nhungamiro iri pamusoro, teerera kune zvinhu zvakaita sekufunga kweEMC, zvinodiwa kwezvakatipoteredza, uye kugona kugadzira. Ita shuwa kutevedzera zvinoenderana neindasitiri zviyero. Bata pamwe nemugadziri wako wePCB kukwidziridza dhizaini nekugadzira maitiro eMCPCBs, kuve nechokwadi chekuita kwepamusoro, kuvimbika, uye kugutsikana kwevatengi.
