Munyika yakafara yemagetsi, chidimbu chePCB chinowanzoshandiswa kureva bhodhi rakadhindwa redunhu.Nekudaro, kune avo vasina kujaira kuomesesa kweiyi tekinoroji yakakosha, izwi iri rinogona kuvhiringa uye rinowanzomutsa mibvunzo yakadai sekuti "PCB inorevei?"Kana iwe ukazviwana iwe uchida kuziva nezvePCBs uye uchida kuwana kunzwisisa kwakajeka kwezvakakosha, iwe uri munzvimbo chaiyo.Iyi blog ine chinangwa chekukupa iwe nyore kunzwisisa tsananguro nezve maPCB, kukosha kwawo uye mashandisiro awo munyika yanhasi yetekinoroji.
Tsanangura PCB
Mabhodhi edunhu akadhindwa (PCBs) zvinhu zvakakosha mumagetsi emazuva ano.Iwo anosanganisira akafuratira mapepa easina-conductive zvinhu senge fiberglass inoshanda sehwaro hwekuisa akasiyana emagetsi zvinhu.Izvi zvikamu zvakabatanidzwa netiweki yemakwara emhangura, anonzi traces, akaiswa pamusoro pebhodhi.
1. Chimiro uye basa
Chinangwa chikuru chePCB ndechekupa tsigiro yemagetsi uye kubatanidza kwemagetsi pakati pezvinhu zvemagetsi.Iyo ine basa rekuona kwakanyatso kubatanidza uye kutaurirana pakati pezvakasiyana zvikamu, zvinosanganisira integrated circuits (ICs), resistors, transistors, capacitors, nezvimwe.Conductive trace mapatani pamabhodhi edunhu anobatsira kurerutsa kuyerera kwemagetsi kuitira kuti zvigadzirwa zvemagetsi zvishande zvakanaka.
2. Zvakanakira PCB
Kubatanidza maPCB mumidziyo yemagetsi kune zvakanakira zvakawanda.Kutanga, yavo compact dhizaini inogonesa miniaturization, optimize nzvimbo mukati memidziyo yemagetsi.Mukuwedzera, kushandisa PCB kunoderedzawo mukana wekukanganisa panguva yegungano, sezvo zvikamu zvakagadzirirwa zvakaiswa pabhodhi, izvo zvinorerutsa maitiro ekugadzira.MaPCB anopawo kusimba kwakakura kana zvichienzaniswa nedzimwe nzira dzewaya.Soldered components inovimbisa kubatana kwakachengeteka uye kuderedza njodzi yewaya dzakasununguka kana kubatanidza kusina kururama.
3. Mhando dzePCBs
MaPCB anogona kusiyana mukuoma, dhizaini, uye huwandu hwematanho kusangana nezvinodiwa zvemashandisirwo chaiwo.Mamwe marudzi akajairika ePCB anosanganisira single-layer, double-layer, uye multi-layer PCBs.A single-layer PCB ine mutsetse mumwe chete wemhangura kune rimwe divi, nepo kaviri-layer PCB ine mhangura inoteedzera mativi ese.Multilayer PCBs ine akawanda akaturikidzana uye akabatanidzwa kuburikidza nemaburi akacherwa anonzi vias, achibvumira huwandu hukuru hwezvikamu kuti zvibatanidzwe uye kuvandudzwa kushanda.
4. PCB yekugadzira nzira
Maitiro ekugadzira PCB anosanganisira akati wandei matanho.Pakutanga, zviyero zvebhodhi uye marongerwo ezvikamu zvakagadzirirwa uchishandisa komputa-inobatsira dhizaini (CAD) software.Kana dhizaini yapera, inotamirwa kubhodhi redunhu kuburikidza nefirimu ine photosensitive kana mask inodzivirira.Idzo nzvimbo dzemhangura dziri pachena dzinozodzikwa pachishandiswa mushonga wemakemikari, zvichisiya zvinenge zvichidiwa.Pakupedzisira, zvikamu zvakasungirirwa pabhodhi uye zvinotengeswa, kupedzisa nzira yegungano.
mukupedzisa
Muchidimbu, mabhodhi edunhu akadhindwa (PCBs) anoita basa rakakosha mumagetsi, achipa kubatanidza kwemagetsi kunodiwa uye tsigiro yemuchina yezvishandiso zvisingaverengeki.Kunzwisisa izvo zvekutanga zvePCBs, kusanganisira chimiro chavo, basa, mabhenefiti, uye maitiro ekugadzira, zvakakosha kuti tinzwisise zvakaomarara zvemagetsi zvatinosangana nazvo zuva rega rega.Sezvo tekinoroji ichienderera mberi, maPCB pasina mubvunzo acharamba ari musimboti wekuvandudza, kushanduka kusangana nematambudziko matsva uye zvinodiwa.
