Best Technology ndeimwe yakanakisisa pcb vagadziri uye akadhindwa redunhu bhodhi vatengesi mu China
Metal Core PCB zvinoreva musimboti (hwaro) zvinhu zvePCB isimbi, kwete yakajairika FR4/CEM1-3, nezvimwewo, uye parizvino, simbi inonyanya kushandiswaMCPCB vagadziri Aluminium, Copper, uye simbi alloy. Aluminium ine yakanaka kutamisa kupisa uye kugona kuburitsa, asi zvakadaro yakachipa; mhangura inotoita zviri nani asi inodhura zvakanyanya, uye simbi inogona kukamurwa kuita simbi yakajairika nesimbi isina tsvina. Iyo yakanyanya kuomarara kupfuura ese aluminium nemhangura, asi yayo yekupisa conductivity yakaderera pane yavo zvakare. Vanhu vanozosarudza yavo base / musimboti zvinhu zvinoenderana nekushandisa kwavo kwakasiyana.
Kazhinji kutaura, aluminium ndiyo yakanyanya hupfumi sarudzo tichifunga nezvekupisa kwayo, kuoma, uye mutengo. Naizvozvo, hwaro / hwepakati zvinhu zveyakajairika Metal Core PCB yakagadzirwa nealuminium. Mukambani yedu, kana pasina zvakakosha zvikumbiro, kana zvinyorwa, iyo simbi yepakati referensi ichave aluminium, ipaposimbi yakatsigirwa PCB zvichareva Aluminium Core PCB. Kana iwe uchida Copper Core PCB, Steel Core PCB, kana Stainless simbi musimboti PCB, iwe unofanirwa kuwedzera akakosha manotsi mudhirowa.
Dzimwe nguva vanhu vanozoshandisa chidimbu chekuti “MCPCB”, pachinzvimbo chezita rizere reMetal Core PCB, Metal Core PCBs, kana Metal Core Printed Circuit Board. Uye zvakare rakashandiswa izwi rakasiyana rinoreva musimboti / hwaro, saka iwe uchaonawo mazita akasiyana eMetal Core PCB, senge. Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB, Metal Core Board, zvichingodaro. Thesimbi musimboti PCBs anoshandiswa pachinzvimbo chechinyakare FR4 kana CEM3 PCBs nekuda kwekugona kuburitsa kupisa kubva kune izvo zvinoriumba. Izvi zvinowanikwa nekushandisa Thermally Conductive Dielectric Layer.
Musiyano mukuru pakati peFR4 board uye asimbi yakavakirwa PCB ndiko kupisa kwemafuta e dielectric zvinhu muMCPCB. Iri rinoita sebhiriji rinopisa pakati pezvikamu zveIC uye ndiro yesimbi inotsigira. Kupisa kunoitwa kubva pasuru kuburikidza nesimbi core kune imwezve kupisa singi. Pane iyo FR4 bhodhi, kupisa kunoramba kwakamira kana kukasaendeswa neiyo topical heatsink. Zvinoenderana nekuyedza lab MCPCB ine 1W LED yakaramba iri padyo nenzvimbo ye25C, ukuwo 1W LED pabhodhi reFR4 yakasvika 12C pamusoro penzvimbo. LED PCB inogara ichigadzirwa neAluminium core, asi dzimwe nguva simbi yepakati PCB inoshandiswawo.
Kubatsira kwesimbi inotsigirwa nePCB
1. Kupisa kupisa
Mamwe ma LED anoparadza pakati pe2-5W yekupisa uye kukundikana kunoitika kana kupisa kubva ku LED kusina kubviswa zvakanaka; chiedza che LED chinobuda chakaderedzwa pamwe nekuderedzwa kana kupisa kunoramba kumire mu LED package. Chinangwa cheMCPCB ndechekubvisa kupisa kubva kune ese topical ICs (kwete maLED chete). Iyo aluminium base uye thermally conductive dielectric layer inoita semabhiriji pakati peICs uye sink yekupisa. Imwe chete yekupisa sink inoiswa yakananga kune iyo aluminium base ichibvisa kudiwa kweakawanda kupisa sink pamusoro pepamusoro-akaiswa zvikamu.
2. Kuwedzera kupisa
Kuwedzera kwekupisa uye kuputika ndiyo yakajairika hunhu hwechinhu, CTE yakasiyana yakasiyana mukuwedzera kwekupisa. Sezvimiro zvavo, aruminiyamu nemhangura zvine yakasarudzika kumberi kune yakajairika FR4, yekupisa conductivity inogona kuita 0.8~3.0 W/c.K.
3. Dimensional kugadzikana
Zviri pachena kuti saizi yesimbi yakavakirwa PCB yakagadzikana kupfuura insulating zvinhu. Saizi shanduko ye2.5 ~ 3.0% apo Aluminium PCB uye aruminiyamu sandwich mapaneru akadziya kubva ku30 ℃ kusvika 140 ~ 150 ℃.
