I-PCB yodongwe
Yintoni i-PCB yodongwe?
I-PCB yeCeramic yitekhnoloji yebhodi yesekethe eprintiweyo esemgangathweni ephucukileyo esebenzisa iipropati ezikhethekileyo zezinto ze-ceramic ukuze inikeze ukusebenza okungenakuthelekiswa nanto. Ngokungafaniyo nezinto ze-PCB zemveli ezifana ne-FR-4, ii-PCB ze-ceramic zenziwe ngezinto ze-ceramic eziphambili ezifana ne-aluminium oxide (Al₂O₃), i-aluminium nitride (AlN), okanye i-beryllium oxide (BeO). Ezi zinto zibonelela ngokuhanjiswa kobushushu okugqwesileyo, amandla oomatshini, kunye nokufakelwa kombane, okwenza ukuba zilungele ukusetyenziswa kwamandla aphezulu, amaza aphezulu, kunye nobushushu obuphezulu.
Ulawulo oluKhethekileyo lobushushu
IiPCB zeCeramic zibalasele ekulawuleni ubushushu, kunye namaxabiso okuqhuba ubushushu aqala kwi-20 ukuya kwi-200 W/m·K (umz., i-aluminium nitride ene-170 W/m·K). Olu kuqhuba ubushushu obuphezulu luqinisekisa ukuchithwa kobushushu okusebenzayo, okuvumela i-PCB ukuba isebenze kumanqanaba aphezulu amandla ngaphandle kokugqithisa kakhulu. Ngokwahlukileyo koko, ii-PCB ze-FR-4 zemveli zinokuqhuba ubushushu kwe-0.3 W/m·K kuphela, nto leyo eyenza ukuba zingafaneleki ukusetyenziswa kwamandla aphezulu.
Ukufakwa kombane okuPhezulu
Izinto zeseramikhi zibonelela ngeempawu ezintle zokuthintela umbane, ezinamandla e-dielectric ukuya kuthi ga kwi-20 kV/mm. Oku kuqinisekisa ukuba i-PCB inokusingatha ukusetyenziswa kwe-high-voltage ngaphandle kokuphazamiseka kombane. Ukongeza, ii-ceramic PCB zine-dielectric constant ephantsi (Dk) kunye ne-dielectric loss ephantsi (Df), ezinciphisa ukuncitshiswa kwesignali kwaye ziqinisekise ukuthembeka kwesignali ephezulu.
Amandla kunye nozinzo lweMishini
IiPCB zeseramikhi zaziwa ngamandla azo oomatshini kunye nokuzinza okulinganayo. Ziyakwazi ukumelana noxinzelelo oluphezulu loomatshini kwaye zigcine imo kunye nokusebenza kwazo naphantsi kweemeko ezinzima. Oku kuzenza zilungele ukusetyenziswa kwiindawo ezinzima, ezifana neenqwelo moya, iimoto, kunye nokuzisebenzela kwemizi-mveliso.

Uthotho lwe-Aluminium Oxide (Al₂O₃)
I-aluminium oxide yeyona nto isetyenziswa kakhulu kwi-ceramic kwi-PCB ngenxa yokuba ixabisa kakuhle kwaye ineempawu ezilungileyo zobushushu nezombane. Ifanelekile kwiintlobo ngeentlobo zezicelo, kubandakanya iimodyuli zamandla, izibane ze-LED, kunye ne-elektroniki yeemoto. -
Uthotho lweAluminiyam Nitride (AlN)
I-aluminium nitride inika amandla aphezulu okuqhuba ubushushu (ukuya kuthi ga kwi-170 W/m·K) kwaye isetyenziswa kwizicelo zamandla aphezulu apho ukusasazwa kobushushu okusebenzayo kubalulekile. Ixhaphake kakhulu kwizixhobo zokukhulisa amandla, ii-laser diodes, kunye nezixhobo zonxibelelwano ezisebenzisa amaxesha amaninzi. -
Uthotho lweBeryllium Oxide (BeO)
I-Beryllium oxide ine-thermal conductivity ephezulu phakathi kwezinto ze-ceramic (ukuya kuthi ga kwi-200 W/m·K) kodwa ayisetyenziswa rhoqo ngenxa yobuthi bayo. Igcinelwe ukusetyenziswa okukhethekileyo kumacandelo omkhosi kunye neenqwelo-moya apho kufuneka khona ukusebenza okugqithisileyo kobushushu.
I-PCB yeCeramic vs. i-PCB yendabuko: Ungakhetha njani?
Izixhobo zePCB zemveli ezifana ne-FR-4 zifanelekile kwiindlela ezisebenzisa amandla aphantsi, ezisebenzisa i-frequency ephantsi ngenxa yokuba zisebenza kakuhle kwaye kulula ukuzisebenzisa. Nangona kunjalo, aziphumeleli kwiimeko ezisebenzisa amandla aphezulu, ezisebenzisa i-frequency ephezulu, kunye ne-high-temperature. IiPCB ze-ceramic, kwelinye icala, zibonelela ngolawulo oluphezulu lobushushu, i-insulation yombane, kunye namandla oomatshini, nto leyo eyenza ukuba zilungele ukusetyenziswa okufunwayo njenge-electronics zamandla, iinkqubo zonxibelelwano ezisebenzisa i-frequency ephezulu, kunye ne-electronics ze-aerospace. Ukukhetha phakathi kwee-PCB ze-ceramic kunye nezemveli kuxhomekeke kwiimfuno ezithile zesicelo.
I-PCB yeCeramic kwiiTekhnoloji eziPhumayo
Uphuhliso olukhawulezileyo lwetekhnoloji entsha efana ne-5G, izithuthi zombane, kunye namandla ahlaziyekayo luqhuba imfuno yee-PCB ezisebenzayo kakhulu. Ii-PCB zeseramikhi zibekwe kakuhle ukuhlangabezana nezi mfuno ngenxa yeempawu zazo ezibalaseleyo zobushushu kunye nombane. Umzekelo, kwizikhululo zesiseko ze-5G, ii-PCB zeseramikhi zinokusingatha amandla aphezulu kunye neemfuno ze-frequency ephezulu zeemodyuli zonxibelelwano. Kwizithuthi zombane, zinokulawula iimeko zamandla aphezulu kunye nobushushu obuphezulu kwiinkqubo ze-elektroniki zamandla.
Imingeni kunye nezisombululo zeMveliso
Ukwenziwa kwee-PCB zeseramikhi kufuna iinkqubo kunye nezixhobo ezikhethekileyo. Inkqubo yokusila ngobushushu obuphezulu kunye nokufakelwa ngokuchanekileyo kweziseko zeseramikhi ngamanyathelo abalulekileyo ekufuneka alawulwe ngokuqinileyo. Iqela lethu, elinamava angaphezu kweshumi leminyaka ekuvelisweni kwee-PCB zeseramikhi, linikezela ngezisombululo eziqala ekupheleni ukuya ekupheleni ukusuka ekukhethweni kwezinto ukuya ekuhlanganisweni kokugqibela. Sinikezela ngeenkonzo zokulinganisa ngokukhawuleza (kwiiyure ezingama-48) kunye nemveliso ephantsi ngolawulo oluqinileyo lomgangatho ukuqinisekisa ukusebenza okuphezulu kunye nokuthembeka.
