Ceramic PCB: guddiga wareegga wareegga substrate dhoobada

Substrate Ceramic wuxuu qeexayaa guddi nidaamsan oo u gaar ah halkaas oo foornada aluminiumka naxaasta ah ay si toos ah ugu dheggan tahay aagga dusha sare (dhinac keli ah ama laba dhinac) alumina (Al2O3) ama aluminium nitride ah (AlN) substrate dhoobada ah oo fudud. Marka la barbardhigo heerka FR-4 ama substrate aluminium khafiif ah, substrate-ka aadka u khafiifka ah ee la sameeyay ayaa leh hufnaan koronto oo aan caadi ahayn, kulaylka sareeyo, alxanka jilicsan ee gaarka ah iyo sidoo kale adkeysi sare oo dammaanad ah, iyo sidoo kale waxaa lagu dhejin karaa sawirro badan sida PCB, oo leh kartida boorsooyinka ee jira ee fantastic. Waxay ku habboon tahay shayada leh jiil diiran oo sarreeya (iftiin sare leh oo LED ah, korantada qorraxda), iyo sidoo kale caabbinta xaalad cimileed oo heer sare ah ayaa doorbideysa goobaha qallafsan ee ka baxsan. Hordhaca Tignoolajiyada Boodhka Wareegga Ceramic
Maxay tahay sababta loo isticmaalo alaabta ceramics si loo soo saaro looxa wareegga? Looxyada wareegga dhoobada waxay ka samaysan yihiin dhoobada elektarooniga ah waxaana lagu samayn karaa qaabab kala duwan. Astaamaha caabbinta heerkulka sare iyo korantada sare ee looxyada wareegga dhoobada ayaa ah kuwa ugu caansan. Faa'iidooyinka dielectric hoose ee joogtada ah iyo khasaaraha dielectric, conductivity kaamerada sare, xasiloonida kiimikada wanaagsan, iyo isku midka ah ballaarinta kulaylka ee qaybaha ayaa sidoo kale muhiim ah. Soo saarista looxyada wareegyada dhoobada waxay isticmaali doonaan tignoolajiyada LAM, taas oo ah tignoolajiyada firfircoonida degdega ah ee laser. Waxaa loo isticmaalaa beerta LED, modules semiconductor awood sare, qaboojiyaha semiconductor, kuleyliyaha elektarooniga ah, korantada korantada, wareegyada hybrid korontada, qaybaha awoodda smart, sahayda korantada beddelka-soo noqnoqda sare, Relays-state adag, elektarooniga baabuurta, isgaarsiinta, aerospace, iyo qalabka elegtarooniga ah ee militariga.
Faa'iidooyinka PCB Ceramic
Si ka duwan FR-4-dhaqameedka, alaabta dhoobada ah waxay leeyihiin waxqabad heer sare ah oo wanaagsan iyo waxqabadka korantada, waxay leeyihiin kuleylka kuleylka sare, xasiloonida kiimikada, xasilloonida kulaylka heer sare ah, iyo waxyaabo kale oo aan lahayn substrates organic. Waa baakad cusub oo ku habboon jiilka wareegyada isku dhafan ee baaxadda weyn iyo korantada korantada.
Faa'iidooyinka ugu muhiimsan:
Dhaqdhaqaaqa kulaylka sare.
Isku xidhka ballaadhinta kulaylka oo aad u habboon.
Filimka birta ah ee birta ah ee adag iyo iska caabinta hoose ee alumina dhoobada wareegga wareegga.
Alxanka substrate waa wanaagsan yahay, heerkulka isticmaalkuna waa sarreeyaa.
Dahaarka wanaagsan.
Khasaare hooseeya oo soo noqnoqonaya.
Isku-dhafka cufnaanta sare ee suurtogalka ah.
Kuma jiraan walxo dabiici ah, way adkaysi u leedahay fallaadhaha cosmic, waxay leedahay isku halaynta sare ee hawada hawada, waxayna leedahay nolol adeeg oo dheer.
Lakabka naxaasta ah kuma jiro lakabka oksaydh waxaana loo isticmaali karaa waqti dheer jawiga yaraynta. PCB-yada dhoobada ah waxay faa'iido iyo waxtar u yeelan karaan looxyada wareegyada daabacan ee kuwan iyo warshado kale oo badan, iyadoo ku xiran baahidaada naqshadeynta iyo wax soo saarka.

Ceramic PCB waa nooc ka mid ah kulaylka samaynta budada dhoobada iyo xidhaha organic, iyo kulaylka conduction dhoobada organic PCB waxaa lagu diyaariyaa kulaylka conductivity of 9-20W/m. Si kale haddii loo dhigo, PCB dhoobada waa loox daabacan oo leh walxo saldhig dhoobo ah, taas oo ah qalab aad u kulul sida alumina, aluminium nitride, iyo sidoo kale beryllium oxide, taas oo samayn karta saameyn degdeg ah oo ku saabsan wareejinta kulaylka meelaha kulul iyo daadinta. dushiisa oo dhan. Intaa waxaa dheer, PCB ceramik waxaa lagu farsameeyay tignoolajiyada LAM, taas oo ah tignoolajiyada biraynta degdega ah ee laysarka. Markaa PCB ceramic waa mid aad u wanagsan oo ka dhici karta dhammaan guddida wareegyada daabacan ee dhaqameed oo leh dhismo ka dhib yar oo leh waxqabad la xoojiyay.

Marka laga reebo  MCPCB , haddii aad rabto in aad isticmaasho PCB cadaadis sare, dahaarka sare, soo noqnoqda sare, heerkulka sare, iyo sare oo la isku halayn karo iyo alaabta elektarooniga ah, ka dibna Ceramic PCB noqon doonaa doorashada ugu fiican.

Waa maxay sababta Ceramic PCB u leedahay waxqabad aad u wanaagsan? Waxaad ka yeelan kartaa aragti kooban oo ku saabsan dhismaheeda aasaasiga ah ka dibna waad fahmi doontaa.
