Ngaba ii-PCB zeseramikhi zibiza kakhulu kuneebhodi ze-FR-4 zemveli?
Ewe, ii-PCB zeseramikhi zibiza kakhulu kuneebhodi ze-FR-4 zemveli kuba i-substrate yeseramikhi yinto entsha nesebenza kakuhle kakhulu kwi-PCB.
Zenziwa njani iiPCB zeseramikhi?
Oku kulandelayo yinkqubo elula yokuvelisa ii-PCB zeseramikhi.
Lungisa izinto eziluhlaza → ukukrola ubhedu olungaphakathi → ukulaminetha → ukubhola → ubhedu olungaphandle → ukuprinta imaski yesolder → unyango lomphezulu → ukuprinta i-silkscreen → uvavanyo oluvulekileyo/olufutshane → ukuhlolwa komgangatho wokugqibela → ukupakishwa.
Ngaba iRichfulljoy ivelisa i-PCB yeseramikhi enezingqimba ezininzi?
Ewe, sinamava amaninzi kakhulu ekuveliseni i-ceramic multilayer PCB. Nceda unxibelelane neqela lethu lentengiso ukuze ufumane ikowuteshini yasimahla yemveliso yakho ye-ceramic PCB.
Yintoni umahluko ophambili: i-ceramic pcb vs i-FR4?
1. Ii-substrates zahlukile;
2. Iindlela zokusetyenziswa zahlukile;
3. Iindleko zahlukile: isiseko se-ceramic esigqunywe ngobhedu sibiza kakhulu;
4, Yahlukile kwimveliso: inkqubo yokuvelisa i-PCB yeseramikhi inzima ngakumbi.
Ngaba kukho naziphi na izinto ezikhethekileyo ekufuneka ziqwalaselwe xa uyila i-PCB yeseramikhi?
Xa siyila iiPCB zeseramikhi, akufuneki sithathe uyilo lula kwaye kufuneka sikhumbule izinto ezininzi ekufuneka siziqwalasele.
Xa siyila i-PCB yeseramikhi, kufuneka sikhethe ngononophelo izinto ze-dielectric ezifunekayo.
I-impedance elawulwayo isoloko ifuneka kwii-PCB ze-ceramic, ngoko ke abayili kufuneka babale ixabiso le-impedance ngokweeparameter zezinto (Er), ubukhulu be-copper, ububanzi be-copper/isithuba, ubukhulu be-dielectric, njl.njl.
Ekubeni izinto zeseramikhi zibiza kakhulu kunezinto zeFR4, uyilo lwebhodi yesekethe yeseramikhi lufanele luqwalasele iindleko zePCB kunye nexabiso lilonke lesicelo.
Ukuba sichonga iingxaki ezinokubakho kwasekuqaleni kwenkqubo yoyilo, sinokuqinisekisa impumelelo kumanqanaba alandelayo. Ngokucwangcisa ngononophelo, ii-PCB zeseramikhi zinokubonelela ngezisombululo ezibalaseleyo kwizicelo ezahlukeneyo. Nceda unxibelelane nathi ngokukhululekileyo ukuba unemibuzo malunga nee-PCB zeseramikhi.
Lingakanani ixesha eliphambili lokwenziwa kwePCB yodongwe?
Ixesha lethu eliqhelekileyo lokufumana imveliso ye-PCB limalunga neveki e-1-3. Kodwa ngamanye amaxesha, sinokudinga iiveki ezimbalwa ukuze sithenge izinto ezikhethekileyo ze-ceramic. Ngoko ke, iimeko ezifana nohlobo lwezinto kunye netekhnoloji esetyenziswa kwi-PCB ziya kumisela ixesha elifanelekileyo lokufumana imveliso ye-PCB ye-ceramic.
Ixabisa malini iPCB yodongwe?
Ezi zinto zilandelayo zimisela ixabiso lePCB yodongwe.
Izinto ezingaphantsi komhlaba (eyona nto ibalulekileyo);
Ubungakanani ngebhetshi nganye;
Iteknoloji yeNkqubo, njengee-vias ezingaboniyo/ezingcwatywe;
Ubunzima ekuvelisweni, njengokunyamezelana kwe-impedance eqinileyo, ukunyamezelana kobubanzi bekopolo eqinileyo;
Ezinye iimfuno ezikhethekileyo.
Yintoni umahluko phakathi kwePCB yeCeramic kunye neTeflon PCB?
Izixhobo zahlukile:
I-Teflon luhlobo lwezixhobo ze-polyimide, oluluhlobo olukhethekileyo lweplastiki esebenza kakhulu. Kodwa i-ceramic luhlobo lwe-compound eyenziwe nge-boron nitride, i-beryllium oxide kunye ne-silicon carbide.
Iindlela zokusetyenziswa zahlukile:
Ii-PCB zeTeflon zihlala zisetyenziswa kwi-microwave nakwi-RF. Kodwa izinto ze-ceramic zihlala ziqiniswa ngokudibanisa nezinye izinto, ngoko ke izinto ze-ceramic zisetyenziswa kakhulu.
Inkqubo kunye neendlela zokuvelisa i-PCB zahlukile:
Oku kungenxa yokuba iimpawu zeentlobo ezimbini zezinto zahlukile ngokupheleleyo.
