Ngaba iiPCB zeceramic zibiza kakhulu kuneebhodi ze-FR-4 zemveli?
Ewe, ii-PCB ze-ceramic zibiza kakhulu kuneebhodi ze-FR-4 zakwantu kuba i-substrate ye-ceramic yinto entsha kunye nokusebenza okuphezulu kwemathiriyeli ye-PCB.
Zenziwa njani iiPCB zeceramic?
Oku kulandelayo yinkqubo yokwenziwa lula yeePCB zeceramic.
Lungisa imathiriyeli ekrwada → umaleko wangaphakathi wokwenza umkhondo wobhedu → ukulamisa → ukugrumba → umaleko womkhondo wobhedu → ushicilelo lwemaski yesolder → ukucocwa komphezulu → ukuprinta kwescreen sesilika → uvavanyo oluvulekileyo/olufutshane → ukuhlolwa komgangatho wokugqibela → ukupakishwa.
Ngaba i-Richfulljoy ivelisa i-PCB ye-ceramic eninzi?
Ewe, sinamava atyebileyo kakhulu kwimveliso ye-ceramic multilayer PCB. Nceda uqhagamshelane neqela lethu lezentengiso ukufumana ikowuti yasimahla yokwenziwa kwakho kwe-ceramic PCB.
Ngowuphi umahluko omkhulu: iCeramic pcb vs FR4?
1. Iisubstrates zahlukile;
2. Ukusetyenziswa kwahlukile;
3. Iindleko ziyahluka: i-copper-clad ceramic substrate ibiza kakhulu;
I-4, Eyahlukileyo kwimveliso: inkqubo yokuvelisa i-ceramic PCB inzima kakhulu.
Ngaba kukho iingqwalasela ezikhethekileyo ekufuneka uzigcine engqondweni xa uyila i-ceramic PCB?
Xa uyila iiPCB zeceramic, akufuneki sithathe uyilo kancinci kwaye kufuneka sigcine iingqwalasela ezininzi engqondweni.
Xa uyila i-ceramic PCB, kufuneka sikhethe ngononophelo imathiriyeli ye-dielectric kwisicelo esifunwayo.
I-impedance elawulwayo isoloko ifuneka kwii-PCB ze-ceramic, ngoko ke abaqulunqi kufuneka babale ixabiso le-impedance ngokweeparamitha eziphathekayo (Er), ubukhulu bobhedu, ububanzi bobhedu / indawo, ubukhulu be-dielectric, njl.
Ekubeni imathiriyeli ye-ceramic ibiza kakhulu kunemathiriyeli ye-FR4, uyilo lwebhodi yesekethe ye-ceramic kufuneka ithathele ingqalelo ixabiso le-PCB kunye nexabiso lesicelo ngokubanzi.
Ukuba sichonga iingxaki ezinokwenzeka ekuqaleni kwenkqubo yoyilo, sinokuqinisekisa impumelelo kwizigaba ezilandelayo. Ngokucwangcisa ngononophelo, iiPCB zeceramic zinokubonelela ngezisombululo ezigqwesileyo kwizicelo ezahlukeneyo. Nceda uqhagamshelane nathi ngokukhululekileyo ukuba unayo nayiphi na imibuzo malunga nee-ceramic PCBs.
Liliphi ixesha eliphambili lokwenza i-ceramic PCB?
Ixesha lethu eliqhelekileyo lokukhokela kwimveliso ye-PCB lijikeleze iiveki ezi-1-3. Kodwa ngamanye amaxesha, sinokufuna iiveki ezimbalwa ukuthenga izinto ezikhethekileyo ze-ceramic. Ke, iimeko ezifana nohlobo lwemathiriyeli kunye netekhnoloji esetyenziswa kwi-PCB iya kumisela elona xesha lichanekileyo lokwenziwa kwe-ceramic PCB.
Lithini ixabiso le-ceramic PCB?
Le miba ilandelayo imisela ixabiso le-ceramic PCB.
I-substrate imathiriyeli (eyona nxalenye ibalulekileyo);
Ubungakanani kwibhetshi nganye;
Inkqubo yeTekhnoloji, njengee-vias ezingaboniyo/ezingcwatywayo;
Ubunzima bokuvelisa, njengokunyamezelana kwe-impedance eqinile, ukunyamezela ububanzi bobhedu;
Ezinye iimfuno ezikhethekileyo.
Yintoni umahluko phakathi kweCeramic PCB kunye neTeflon PCB?
Iimathiriyeli zahlukile:
I-Teflon luhlobo oluthile lwe-polyimide, oluluhlobo olukhethekileyo lweplastiki ephezulu yokusebenza. Kodwa i-ceramic luhlobo lwekhompawundi eyenziwe nge-boron nitride, i-beryllium oxide kunye ne-silicon carbide.
Ukusetyenziswa kwahlukile:
IiPCB zeTeflon zihlala zisetyenziselwa usetyenziso lwemicrowave kunye neRF. Kodwa izinto ze-ceramic zihlala ziqiniswa kunye nezinye izinto, ngoko ke ii-substrates ze-ceramic zisetyenziswa ngokubanzi.
Inkqubo yemveliso yePCB kunye nobuchule bohlukene:
Oku kungenxa yokuba iimpawu zezi ntlobo zimbini zemathiriyeli zahluke ngokupheleleyo.
