Ni ubuhe bwoko bw'imirongo ishobora gukoreshwa hamwe na PCB za keramik?
Hari ubwoko bwinshi bw'imiyoboro ishobora gukoreshwa hamwe na PCB za keramike. Ingero zikurikira ni zimwe muri zo.
Imiyoboro yihuta cyane
Imiyoboro ya RF
Imiyoboro yo gukwirakwiza ubushyuhe
Ingufu zitanga amashanyarazi
Imiyoboro yo gupima ubushyuhe
Ese PCB za keramik zihenze kurusha imbaho zisanzwe za FR-4?
Yego, PCB za keramike zirahenze kurusha imbaho zisanzwe za FR-4 kubera ko substrate ya keramike ari ibikoresho bishya kandi bihebuje bya PCB.
PCB zikozwe mu buryo ki mu ibumba?
Ibi bikurikira ni uburyo bworoshye bwo gukora PCB za ceramic.
Tegura ibikoresho fatizo → gushushanya umuringa w'imbere → gusiga lamination → gucukura → gusohora umuringa w'imbere → gucapa maske yo gusoda → gutunganya ubuso → gucapa silkscreen → gupima vuba/kureba neza → gusuzuma ubuziranenge bwa nyuma → gupfunyika.
Ese Richfulljoy ikora PCB ya keramik ifite ibara ryinshi?
Yego, dufite ubunararibonye bwinshi mu gukora PCB za ceramic. Nyamuneka hamagara itsinda ryacu rishinzwe kugurisha kugira ngo ubone ibiciro ku buntu ku bikoresho byawe bya ceramic PCB.
Ni irihe tandukaniro nyamukuru: PCB ya Ceramic ugereranyije na FR4?
1. Ibyuma biratandukanye;
2. Imikoreshereze iratandukanye;
3. Ibiciro biratandukanye: icyuma gikozwe mu muringa gihenze cyane;
4, Itandukaniro mu musaruro: inzira yo gukora PCB za ceramic iragoye cyane.
Ese hari ibintu byihariye ugomba kuzirikana mu gihe ushushanya PCB ya ceramic?
Mu gihe dushushanya PCB za ceramic, ntitugomba gufata igishushanyo mbonera nk'ikintu cyoroshye kandi tugomba kuzirikana ibintu byinshi.
Mu gihe dushushanya PCB ya ceramic, tugomba guhitamo neza ibikoresho bya dielectric kugira ngo bikoreshwe.
Impedansi igenzurwa ihora ikenewe muri PCB za ceramic, bityo abashushanya bagomba kubara agaciro ka impedansi hakurikijwe ibipimo by'ibikoresho (Er), ubunini bw'umuringa, ubugari/umwanya w'umuringa, ubunini bwa dielectric, nibindi.
Kubera ko ibikoresho bya ceramic bihenze cyane kurusha ibikoresho bya FR4, igishushanyo mbonera cy'ikibaho cya ceramic kigomba kuzirikana ikiguzi cya PCB n'igiciro rusange cy'ikoreshwa.
Iyo tubonye ibibazo bishobora kubaho mu ntangiriro z'igikorwa cyo gushushanya, dushobora kwemeza ko bizagenda neza mu byiciro bya nyuma. Dukoresheje igenamigambi ryitondewe, PCB za ceramic zishobora gutanga ibisubizo byiza ku bikorwa bitandukanye. Twandikire ku buntu niba ufite ikibazo kijyanye na PCB za ceramic.
Igihe cyo gukora PCB za ceramic ni ikihe?
Igihe gisanzwe cyo gukora PCB ni hagati y'icyumweru kimwe na bitatu. Ariko rimwe na rimwe, dushobora gukenera ibyumweru bike kugira ngo tugure ibikoresho byihariye bya ceramic. Rero, imiterere nk'ubwoko bw'ibikoresho n'ikoranabuhanga bikoreshwa kuri PCB bizagena igihe nyacyo cyo gukora PCB za ceramic.
Igiciro cya PCB ya ceramic ni ikihe?
Ibintu bikurikira bigena ikiguzi cya PCB ya ceramic.
Ibikoresho byo mu butaka (igice cy'ingenzi cyane);
Ingano kuri buri itsinda;
Ikoranabuhanga mu gutunganya ibintu, nk'ibikoresho byo mu bwoko bwa "vices" bidafite aho bibonywe cyangwa bitwikiriwe;
Ingorane mu nganda, nko kwihanganira impedance cyane, kwihanganira ubugari bw'umuringa bukabije;
Ibindi bisabwa byihariye.
Ni irihe tandukaniro riri hagati ya PCB ya Ceramic na Teflon PCB?
Ibikoresho biratandukanye:
Teflon ni ubwoko bw'ibikoresho bya polyimide, bikaba ari ubwoko bwihariye bwa pulasitiki ikora neza cyane. Ariko ceramic ni ubwoko bw'ibintu bikozwe muri boron nitride, beryllium oxide na silicon carbide.
Imikoreshereze iratandukanye:
Teflon PCBs ikoreshwa buri gihe mu gukoresha mikoroonde na RF. Ariko ibikoresho bya ceramic akenshi bikomezwa n'ibindi bikoresho, bityo substrates za ceramic zikoreshwa cyane.
Uburyo bwo gukora PCB n'ubuhanga biratandukanye:
Ibi biterwa nuko imiterere y'ubwoko bubiri bw'ibikoresho itandukanye rwose.
