I-Ceramic PCB ye-ceramic eyodwa nezinhlangothi ezimbili I-PCB yenza ama-Ceramic Substrates| I-YMS PCB

I-Ceramic PCB: ibhodi lesifunda se-ceramic substrate

I- Ceramic Substrate ichaza ibhodi lenqubo eliyingqayizivele lapho ucwecwe lwe-aluminium yethusi lubambelele ngokuqondile endaweni (uhlangothi olulodwa noma olukabili) lwe-alumina (Al2O3) noma i-aluminium nitride (AlN) engasindi ye-ceramic substrate lapho kushisa. Uma iqhathaniswa ne-FR-4 ejwayelekile noma i-aluminium substrate enesisindo esilula, i-substrate eyinhlanganisela ye-ultra-mncane eyenziwe inamandla akhethekile okufakwa kukagesi, ukuguquguquka okuphezulu kwe-thermal, ukuthengiswa okukhethekile okuthambile kanye nokuqina kwebhondi ephezulu, futhi ingaqoshwa ihluzo eziningi njenge-PCB, kumnandi ekhona lugging ikhono. Ilungele izinto ezinesizukulwane esishisayo (i-LED ekhanya kakhulu, amandla elanga), kanye nokumelana nesimo sezulu esihle kakhulu kungcono kumasethingi angaphandle amabi. I-Ceramic Circuit Board Technology Isingeniso
Kungani usebenzise izinto ze-ceramics ukukhiqiza amabhodi wesifunda? Amabhodi wesifunda se-Ceramic enziwe nge-ceramics kagesi futhi angenziwa ngezindlela ezihlukahlukene. Izici zokumelana nokushisa okuphezulu kanye nokufakwa kukagesi okuphezulu kwamabhodi wesifunda se-ceramic yizona ezivelele kakhulu. Izinzuzo zokungaguquguquki kwe-dielectric ephansi kanye nokulahlekelwa kwe-dielectric, ukuqhutshwa kokushisa okuphezulu, ukuzinza okuhle kwamakhemikhali, kanye ne-coefficient yokwandisa ukushisa okufanayo ezingxenyeni nakho kubalulekile. Ukukhiqizwa kwamabhodi wesifunda se-ceramic kuzosebenzisa ubuchwepheshe be-LAM, okuwubuchwepheshe be-laser quick activation metallization. Asetshenziswa emkhakheni we-LED, amamojula anamandla amakhulu we-semiconductor, iziqandisi ze-semiconductor, ama-heaters kagesi, amasekhethi okulawula amandla, amasekhethi ahlanganisiwe wamandla, izingxenye zamandla ahlakaniphile, izinsiza zamandla ezishintshashintshayo ezihamba phambili, ukudluliselwa kombuso okuqinile, ugesi wezimoto, ukuxhumana, i-aerospace, kanye nezingxenye ze-electronics zempi.
Izinzuzo ze-Ceramic PCB
Ngokungafani ne-FR-4 yendabuko, izinto ze-ceramic zinokusebenza okuhle kwe-high-frequency kanye nokusebenza kukagesi, zine-conductivity ephezulu ye-thermal, ukuqina kwamakhemikhali, ukuqina okuhle kakhulu kwe-thermal, nezinye izakhiwo ezingenayo i-organic substrates. Kuyinto entsha efanelekile yokupakisha ukukhiqizwa kwamasekhethi amakhulu ahlanganisiwe namamojula we-electronic wamandla.
Izinzuzo Main:
Higher conductivity ezishisayo.
Okufanayo okwengeziwe kwe-coefficient yokwandisa okushisayo.
Ibhodi lesifunda lensimbi eliqinile neliphansi le-alumina ceramic.
I-solderability ye-substrate yinhle, futhi izinga lokushisa lokusetshenziswa liphezulu.
I-insulation enhle.
Ukulahleka kwe-high-frequency ephansi.
Ukuhlanganiswa okuphezulu kakhulu kungenzeka.
Ayiqukethe izithako zemvelo, imelana nemisebe ye-cosmic, inokwethenjelwa okuphezulu emkhathini, futhi inempilo ende yesevisi.
Ungqimba lwethusi aluqukethe ungqimba lwe-oxide futhi lungasetshenziswa isikhathi eside endaweni yokunciphisa. Ama-Ceramic PCB angaba wusizo futhi asebenze kahle kumabhodi esekethe aphrintiwe kulezi zimboni nezinye eziningi, kuye ngedizayini yakho nezidingo zokukhiqiza.

I-Ceramic PCB iwuhlobo lokushisa oluqhuba i-ceramic powder kanye ne-organic binder, kanye ne-heat conduction organic ceramic PCB ilungiselelwa ekushiseni okushisayo okungu-9-20W/m. Ngamanye amazwi, i-ceramic PCB iyibhodi lesifunda eliphrintiwe elinesisekelo se-ceramic material, okuyizinto ezithinta ukushisa kakhulu ezifana ne-alumina, i-aluminium nitride, kanye ne-beryllium oxide, engenza umphumela osheshayo ekudluliseni ukushisa kude nezindawo ezishisayo futhi zilahle. phezu kobuso bonke. Ngaphezu kwalokho, i-ceramic PCB yakhiwe ngobuchwepheshe be-LAM, okuwubuchwepheshe obusebenzisa i-laser rapid activation metallization. Ngakho-ke i-ceramic PCB iguquguquka kakhulu engathatha indawo yalo lonke ibhodi lesifunda eliphrintiwe elingokwesiko elinokwakhiwa okungenzima kangako nokusebenza okuthuthukisiwe.

Ngaphandle kwe-  MCPCB , uma ufuna ukusebenzisa i-PCB ekucindezelweni okuphezulu, ukwahlukanisa okuphezulu, imvamisa ephezulu, izinga lokushisa eliphezulu, kanye nemikhiqizo ye-elekthronikhi enokwethenjelwa ephezulu nencane, i-Ceramic PCB izoba yisinqumo sakho esingcono kakhulu.

Kungani i-Ceramic PCB inokusebenza okuhle kakhulu? Ungaba nombono omfushane ngesakhiwo sawo esiyisisekelo futhi uzoqonda.
