zitsulo pachimake pcb 1Layer Thermoelectric Copper base Board | Mtengo wa YMSPCB

Kodi PCB yochokera mkuwa ndi chiyani?

PCB ya mkuwa ndiyokwera mtengo kwambiri muzitsulo zapakati pa PCB , zomwe zimakhala ndi matenthedwe abwino kwambiri kuposa aluminiyamu PCB ndi PCB yachitsulo. Oyenera kuwongolera pafupipafupi komanso kusiyanasiyana kwa kutentha komanso kutsika komanso kuwongolera bwino zida zoyankhulirana zotayira kutentha ndi mafakitale okongoletsa nyumba.

A Metal Core Printed Circuit Board (MCPCB), yomwe imadziwikanso kuti PCB yotentha kapena PCB yothandizidwa ndi zitsulo, ndi mtundu wa PCB womwe uli ndi zitsulo monga maziko ake a gawo lofalitsa kutentha kwa bolodi. Chitsulo chokhuthala (nthawi zonse aluminium kapena mkuwa) chimakwirira mbali imodzi ya PCB. Chitsulo chachitsulo chikhoza kutanthauza chitsulo, kukhala pakati penapake kapena kumbuyo kwa bolodi. Cholinga cha pachimake cha MCPCB ndikuwongolera kutentha kutali ndi zigawo zofunika kwambiri za board ndikupita kumadera osafunikira kwambiri monga zitsulo za heatsink kapena zitsulo. Zitsulo zoyambira mu MCPCB zimagwiritsidwa ntchito ngati m'malo mwa FR4 kapena CEM3 board.

Pakatikati pazitsulo za PCB yotentha imatha kukhala aluminium (aluminiyamu pachimake PCB), mkuwa (PCB yamkuwa kapena PCB yamkuwa yolemera) kapena kusakaniza kwa ma aloyi apadera. Chodziwika kwambiri ndi aluminium pachimake PCB. Zida zina, monga mkuwa kapena chitsulo, nthawi zina zimapemphedwa koma sizovomerezeka. Zida zachitsulo za PCB ndizovuta kwambiri ndipo kudula PCB kukhala tiziduswa tating'onoting'ono kumatha kuyambitsa mavuto. Mfundo zina posankha zitsulo PCB zipangizo ndi mankhwala mu kupanga ndi ngati zitsulo adzachita nawo.

Makulidwe azitsulo zazitsulo mu mbale zoyambira za PCB nthawi zambiri zimakhala 30 mil - 125 mil, koma mbale zowonda komanso zoonda ndizotheka.

Makulidwe a zojambula zamkuwa a MCPCB amatha kukhala 1 - 10 oz. Kuchuluka kwa kutentha kwambiri m'mabwalo osindikizira osindikizira kumabweretsa kuwonongeka kwa zipangizo. Zipangizo zamagetsi zomwe zimatulutsa kutentha kochuluka sizingathe kuzizidwa nthawi zonse pogwiritsa ntchito mafani ochiritsira. Kuzizira kochititsa chidwi kudzera pazitsulo zachitsulo ndi njira yabwino. Mu kuzirala kochititsa chidwi, kutentha kumasamutsidwa kuchokera ku gawo limodzi lotentha kupita ku gawo lozizira kwambiri pokhudzana mwachindunji. Izi zimagwira ntchito bwino chifukwa kutentha kumafuna kusunthira ku chinthu chilichonse kapena sing'anga yomwe ili yozizira. YMSPCB ndi wopanga ma PCB ndi ma PCBA ku China. Malo athu akuluakulu amatha kusamalira madongosolo ang'onoang'ono a volume popanda kuletsa zidutswa zochepa; mutha kuyitanitsanso PCB imodzi. Timapereka ma prototypes achangu a PCB ndi ntchito zosonkhana za turnkey PCB. Chilichonse chikhoza kuchitika pansi pa denga limodzi, ndipo timakhala ndi udindo pazochitika zonse. Akatswiri athu amakhala okonzeka nthawi zonse kukuthandizani kuti mubwere ndi mapangidwe abwino kuti mugwire bwino ntchito.

Timatsimikizira ma PCB ochita bwino kwambiri omwe ali ndi khalidwe lapadera pamtengo wotsika. Tili ndi kasamalidwe kokhazikika kabwino, komwe kumatsimikiziridwa ndi RoHS, IOS, ndi UL. Timatsatira miyezo yamakampani, ndipo ukadaulo wathu waposachedwa umapangitsa chilichonse kukhala chodalirika komanso chachangu. Mutha kulumikizana nafe nthawi iliyonse, ndipo gulu lathu lothandizira makasitomala 24/7 likuthandizani.

Chifukwa chiyani ma PCB achitsulo pachimake?

Kuchuluka kwa kutentha kwambiri m'mabwalo osindikizira osindikizira kumabweretsa kuwonongeka kwa zipangizo. Zipangizo zamagetsi zomwe zimatulutsa kutentha kochuluka sizingathe kuzizidwa nthawi zonse pogwiritsa ntchito mafani ochiritsira. Kuzizira kochititsa chidwi kudzera pazitsulo zachitsulo ndi njira yabwino. Mu kuzirala kochititsa chidwi, kutentha kumasamutsidwa kuchokera ku gawo limodzi lotentha kupita ku gawo lozizira kwambiri pokhudzana mwachindunji. Izi zimagwira ntchito bwino chifukwa kutentha kumafuna kusunthira ku chinthu chilichonse kapena sing'anga yomwe ili yozizira.
