Mabhodhi edunhu akadhindwa anoshandiswa zvakanyanya mumagetsi akasiyana-siyana uye matekinoroji, achiaita midziyo yakakosha. Ingave nharembozha, komputa kana muchina wakaoma, uchaona kuti pcb ine basa rekuita kwechishandiso. Kana iyo yakadhindwa yedunhu bhodhi ine kukanganisa kana matambudziko ekugadzira, inogona kukonzera chigadzirwa chekupedzisira kusashanda uye kukonzera kusagadzikana. Mumamiriro ezvinhu aya, vagadziri vanozofanira kuyeuka zvishandiso izvi uye kushandisa nguva yakawanda uye zviwanikwa kugadzirisa kukanganisa.
Ichi ndicho chimwe chezvikonzero chikuru nei vazhinji vanogadzira vanotendeukira kune vanogadzira pcb uye vagadziri vekugadzira nehunyanzvi uye kuyedza.
Nei pcb board ichifanira kuongororwa?
Chikamu chekuyedza chekugadzira PCB ndechimwe chezvikamu zvakakosha. Kana iwe usingaedze wako pcb bhodhi, pangava zvimwe zvikanganiso uye matambudziko vakanga kufuratirwa panguva kugadzirwa danho. Matambudziko aya anogona kupedzisira akonzera kutadza kwemunda uye kukanganisa. Kuti uderedze mukana wekukundikana uye kuchengetedza kugutsikana kwevatengi, zvakakosha kuita maitiro ekuedzwa kuti uone kuti mabhodhi edunhu akadhindwa uye zvikamu zvinoshanda zvizere. Kune maitiro ekuyedza mukati mechikamu chekugadzira, icho chinokutendera kuti uone zvikanganiso uye matambudziko kare kwete muchikamu chekupedzisira chekuyedza.
Yakadhindwa dhizaini bhodhi dhizaini uye makambani ekugadzira anowanzo kuve nekuchenjerera uye kwakanyatso kuyedza maitiro kuti ave nechokwadi chekuti yekupedzisira yakadhindwa redunhu bhodhi ndeyemhando yepamusoro.
PCB chikamu chekuongorora
Chikamu chekuyedza chinowanzo chikamu chakakwana uye chinoda kutarisisa kukuru kune zvakadzama. The pcb bhodhi inoumbwa siyana zvakaoma zvinoriumba. Izvi zvinogona kusanganisira capacitors, resistors, transistors, diodes uye fuse. Izvi ndizvo zvikamu zvikuru zvinoda kuongororwa chero zviratidzo zvekusagadzikana uye kusashanda.
Capacitors-Capacitors zviduku zvemagetsi zvinochengeta simba nenzira yemagetsi emagetsi. Capacitors vane basa rekuvhara kuyerera kweiyo yakananga ikozvino uye kuita kuti zvikwanise kuchengetedza zvisina kunanga ikozvino uchichengetedza simba. Kuyedza aya ma capacitor, voltage inoiswa kuyedza kuti inoshanda sezvinodiwa. Zvikasadaro, mhinduro dzakasiyana dzinogona kuoneka, zvichiratidza mapfupi maseketi, kuvuza, kana kutadza kwecapacitor.
Diode-A diode chinhu chidiki chemagetsi chinogona kutamisa ikozvino mune imwe nzira. Painotumira ikozvino mune imwe nzira, inovhara reverse ikozvino. Iyo diode mudziyo unonzwisa tsitsi, uye kuiyedza kunoda kutarisirwa. Zvinokurudzirwa kubvunzurudza nyanzvi usati waedza nhengo dzakaoma kudzivirira kukanganisa
Resistor-Resistor chimwe chezvinhu zvikuru zvinoumba pcb bhodhi. Izvi zvidiki zvemagetsi zvine materminal maviri anoburitsa voltage kubva kune yazvino. Kuti uedze kupikisa uku, unogona kushandisa ohmmeter. Kamwe kupikisa kwave kwakasarudzika, unogona kushandisa dhijitari multimeter uye ubatanidze inotungamira kune inopikisa yekuyedza. Kana kuverenga kwakanyanyisa, kungave kuri nekuda kwekuvhura resistor.
Sezvo pcb bhodhi rinoumbwa zvakasiyana-siyana zvakaoma zvemagetsi zvinoriumba, zvinokosha zvikuru kuedza kana pcb bhodhi ane chero kukanganisa kana zvikanganiso zvingaita kuti redunhu bhodhi kuti kusashanda. Chimwe nechimwe chikamu chinofanirwa kutariswa uye kuyedzwa kuchengetedza inoshanda yakadhindwa redunhu bhodhi pakukwanisa kwayo kuzere
Fastline Circuits Co., Limited.inotora zvinhu zvitatu zviri pamusoro apa semapoinzi ekubudirira, uye vatengi vanogona kusarudza zviri nyore mugadziri akakodzera. Panguva imwecheteyo, isu tinofanirwa kutarisisa kutaurirana uye kuchinjana nevagadziri, kuitira kuti mativi maviri aya aumbe "kuwirirana kunobatsira uye kuhwina-kuhwina" nyika, uye zviri nani kukurudzira chigadzirwa purojekiti kubatana.
