MaPCB eceramic anodhura kupfuura mabhodhi eFR-4 echinyakare here?
Ehe, maPCB esimbi anodhura kupfuura mabhodhi ekare eFR-4 sezvo simbi yesimbi iri itsva uye inoshanda zvakanaka pane PCB.
MaPCB eceramic anogadzirwa sei?
Inotevera inzira iri nyore yekugadzira maPCB eceramic.
Gadzirirai zvinhu zvakabikwa → kuchekerera kwemhangura yemukati → kurongedza → kubhoorera → kuburitsa jira remhangura → kudhinda mask yesolder → kurapwa kwepamusoro → kudhinda silkscreen → kuyedza kwakavhurika/kupfupi → kuongororwa kwemhando yepamusoro → kurongedza.
Richfulljoy inogadzira PCB yeceramic ine layer yakawanda here?
Ehe, tine ruzivo rwakakura mukugadzira ceramic multilayer PCB. Ndapota taurai nechikwata chedu chekutengesa kuti muwane mutengo wemahara wekugadzira ceramic PCB yenyu.
Musiyano mukuru ndeupi: Ceramic pcb vs FR4?
1. Zvigadziko zvakasiyana;
2. Mashandisirwo akasiyana;
3. Mitengo yakasiyana: substrate yesimbi yakaputirwa nemhangura inodhura zvakanyanya;
4, Kusiyana mukugadzirwa: maitiro ekugadzira PCB yeceramic akaoma zvikuru.
Pane zvinhu zvakakosha here zvekufunga nezvazvo pakugadzira PCB yeceramic?
Pakugadzira maPCB eceramic, hatifaniri kutora dhizaini yacho zvishoma uye tinofanira kufunga nezvezvinhu zvakati wandei.
Pakugadzira PCB yeceramic, tinofanira kunyatsosarudza zvinhu zve dielectric zvekushandisa kwatinoda.
Kudzora kudzorwa kunodiwa nguva dzose mumaPCB eceramic, saka vagadziri vanofanira kuverenga kukosha kwekudzivirira zvichienderana nezvinodiwa nezvinhu (Er), ukobvu hwemhangura, upamhi hwemhangura/nzvimbo, ukobvu hwe dielectric, nezvimwewo.
Sezvo zvinhu zveceramic zvichidhura zvakanyanya kupfuura zvinhu zveFR4, dhizaini yebhodhi recircuit receramic inofanira kufunga nezvemutengo wePCB uye mutengo wekushandisa wese.
Kana tikaona matambudziko angangoitika pakutanga kwekugadzirwa, tinogona kuva nechokwadi chekubudirira muzvikamu zvinotevera. Nekuronga kwakanaka, maPCB eceramic anogona kupa mhinduro dzakanaka kumashandisirwo akasiyana-siyana. Ndapota taurai nesu makasununguka kana muine mibvunzo maererano nemaPCB eceramic.
Inguva ipi yekutungamira yekugadzira PCB yeceramic?
Nguva yedu yakatarwa yekugadzira PCB inenge vhiki imwe kusvika nhatu. Asi dzimwe nguva, tingada mavhiki mashoma kuti titenge zvinhu zveceramic. Saka, mamiriro akaita semhando yezvinhu uye tekinoroji inoshandiswa paPCB ndiyo ichasarudza nguva chaiyo yekugadzira PCB yeceramic.
Mutengo wePCB yeceramic unoita sei?
Zvinhu zvinotevera zvinosarudza mutengo wePCB yeceramic.
Zvinhu zvepasi pevhu (chikamu chakakosha);
Huwandu pabhechi rimwe nerimwe;
Tekinoroji yeMaitiro, senge ma-vias asina kuvonekwa/akavigwa;
Kuoma mukugadzira, zvakaita sekushivirira kwakanyanya impedance, kushivirira kwakasimba kwehupamhi hwemhangura;
Zvimwe zvinodiwa zvakakosha.
Chii chiri musiyano uripo pakati peCeramic PCB neTeflon PCB?
Zvinhu zvakasiyana:
Teflon imhando yezvinhu zvepolyimide, inova mhando yakakosha yepurasitiki inoshanda zvakanyanya. Asi ceramic imhando yemusanganiswa wakagadzirwa ne boron nitride, beryllium oxide uye silicon carbide.
Mashandisirwo akasiyana:
Mateflon PCB anoshandiswa nguva dzose pakushandisa microwave neRF. Asi zvinhu zveceramic zvinowanzosimbiswa nekubatanidzwa kwezvimwe zvinhu, saka zvinhu zveceramic zvinoshandiswa zvakanyanya.
Maitiro ekugadzira PCB uye matekiniki akasiyana:
Izvi zvinodaro nekuti hunhu hwemhando mbiri dzezvinhu zvakasiyana zvachose.
