Mwachidule, PCB yopanda kanthu imatanthawuza kusungitsa malo osindikizidwa popanda mabowo kapena zinthu zamagetsi. Nthawi zambiri amatchedwa PCBS ndipo nthawi zina amatchedwa PCB. Bokosi la PCB lopanda kanthu lili ndi njira zoyambira zokha, mapangidwe, zitsulo zokutira zachitsulo ndi pcb gawo.
Kodi kugwiritsa ntchito bwanji bolodi ya PCB?
PCB yopanda kanthu ndi mafupa a gulu la madera achikhalidwe. Imatsogolera masiku ano komanso masiku ano njira zoyenera ndipo imagwiritsidwa ntchito m'njira zamagetsi ambiri.
Kuphweka kwa PCB yopanda kanthu kumapereka mainjiniya ndi opanga ufulu wokwanira kuti aonjezere zinthu zomwe zingafunikire. Bungwe lopanda tanthauzo ili limapereka kusinthasintha ndipo kumathandizira kupanga.
Bungwe la PCB ili limafuna kuti ntchito ina yambiri kuposa njira zina zowonera, koma zimatha kungokhala ndi msonkhano nditapanga msonkhano ndi kupanga. Izi zimapangitsa PCB matabwa osankha zotsika mtengo komanso ogwira mtima kwambiri.
Bungwe losavala limangothandiza pambuyo powonjezera zinthu. Cholinga chachikulu cha PCB yopanda kanthu ndikuti mukhale gulu lonse la madera athunthu. Ngati zikufanana ndi zigawo zoyenera, zimagwiritsidwa ntchito zingapo.
Komabe, izi sizongogwiritsa ntchito mabodi a PCB. PCB yopanda kanthu ndi gawo labwino kwambiri kuti mupange board yoyeserera mu bolodi ya madera. Ndikofunikira kuteteza mavuto ambiri omwe angachitike mtsogolo.
Chifukwa chiyani board baard ikuyesedwa?
Pali zifukwa zambiri zoyeserera maadiboti osavala. Monga gulu la madera ozungulira, pcb board kulephera pambuyo kukhazikitsa kudzadzetsa mavuto ambiri.
Ngakhale sizachilendo, pcb yopanda kanthu ikhoza kukhala kale musanawonjezere zigawo zikuluzikulu. Mavuto ofala kwambiri achulukirachulukira, akuwonjezereka ndi mabowo. Ngakhale zolakwika zazing'ono zimatha kuyambitsa zolephera zopanga.
Chifukwa cha kuchuluka kwa matenda oyambitsa matenda, kufunikira kwa matabwa ambiri a milgafer pcb akupitiliza kuwonjezeka, kupangitsa kuti abowo akhale ofunika kwambiri. Pambuyo kusonkhanitsa PCB yama 100, kamodzi chifukwa cholephera chimachitika, ndizosatheka kukonza.
Ngati PCB yosavala ndi mafupa a gulu la madera, ziwalo ndi ziwalo ndi minofu. Zigawo zikhoza kukhala zodula kwambiri ndipo nthawi zambiri zimakhala zovuta, kotero pakapita nthawi, kukhala ndi chimango cholimba kumatha kupewa zinthu zomaliza zothana ndi zokwanira.
Mitundu ya Kuyeserera kwa Board
Momwe Mungadziwire Ngati PCB yawonongeka?
Izi zimafunikira kuyesedwa munjira ziwiri: zamagetsi ndi kukana.
Mayeso osavala bwino amawonanso kudzipatula komanso kupitiliza kwa magetsi. Kuyesa kwa chiwongola dzanja kumayesa kulumikizana pakati pa kulumikizana kwapadera, pomwe mayeso opitiliza kuwonetsetsa kuti palibe malo otseguka omwe angasokoneze zomwe zingasokoneze zomwe zikuchitika.
Ngakhale kuyezetsa kwamagetsi kuli kofala, kuyesa kukana sichachilendo. Makampani ena amagwiritsa ntchito kuphatikiza awiriwo, m'malo mongogwiritsa ntchito mayeso amodzi.
Kuyesa Kukaniza Kutumiza kwapano kudzera kwa wochititsa kuti ayesere kukana. Kulumikizana kwa nthawi yayitali kapena kuwonera kumabweretsa kuponderezana kwakukulu kuposa kufupikira kapena kwaukadaulo.
Kuyesa kwa Batch
Pazinthu zomwe zili ndi polojekiti ina, opanga madera osindikizidwa nthawi zambiri amagwiritsa ntchito zokuza zoyeserera, zotchedwa "mayesero." Kuyezetsa kumeneku kumagwiritsa ntchito zikhomo zonyamula masika kuti ziyesere chilichonse pa PCB.
Kuyeserera kokhazikika ndi koyenera kwambiri ndikutha kumalizidwa m'masekondi ochepa chabe. Choyipa chachikulu ndichotsika mtengo komanso kusowa kosinthasintha. Mapangidwe osiyanasiyana a PCB amafunikira filimu yosiyanasiyana ndi zikhomo (zoyenera kupanga misa).
Mayeso a Prototype
Kuyesa kwa Probeng Probe kumagwiritsidwa ntchito. Manja awiri aboti okhala ndi ndodo amagwiritsa ntchito pulogalamu pulogalamu yoyesa kulumikizana.
Poyerekeza ndi mayeso okhazikika, zimatenga nthawi yayitali, koma ndizotsika mtengo komanso zosinthika. Kuyesa mapangidwe osiyanasiyana ndikosavuta ngati kuyika fayilo yatsopano.
Ubwino wa Kuyeserera kwa Board
Kuyesa kwa board kulibe zabwino zambiri, popanda zovuta zazikulu. Izi popanga njira yopanga imatha kupewa mavuto ambiri. Kuchuluka kwa ndalama zochepa kumatha kusunga ndalama zambiri zokonza komanso zobwezeretsa.
Kuyesedwa kwa board kumathandiza kuti mupeze mavuto kumayambiriro pakupanga. Kupeza vutoli kumatanthauza kupeza zomwe zimayambitsa vutoli ndikutha kuthetsa vutoli ndi muzu wake.
Ngati vutoli likupezeka motsatira, zingakhale zovuta kupeza vuto la mizu. Bolo la PCB litaphimbidwa ndi zigawo zikuluzikulu, ndizosatheka kudziwa zomwe zidayambitsa vutoli. Kuyesedwa koyambirira kumathandizanso kuthetsa mavuto chifukwa cha chomwe chimayambitsa.
Kuyesa kumathandizanso njira yonseyo. Ngati mavuto apezeka ndikusinthidwa mu gawo la Prototype, magawo opanga omwe ali ndi chifukwa amatha popanda choletsa.
Sungani Project Project kudzera pakuyesa kwa board
Nditadziwa kuti ndi gulu lopanda tanthauzo lanji, ndipo kumvetsetsa kufunikira kwa board yoyeserera. Mudzaona kuti ngakhale njira yoyamba yolowererayo imachedwa chifukwa choyesedwa, nthawi yomwe yasungidwa ndi board yosanja yoyesedwa ndi nthawi yomwe imadya. Kudziwa ngati pali zolakwika mu PCB kungapangitse kuthetsa mavuto pambuyo pake.
Gawo loyambirira ndi nthawi yotsika mtengo kwambiri yambiri yoyeserera. Ngati gulu loyang'anira madera limalephera ndipo mukufuna kukonza nthawi yomweyo, mtengo wotayika ungakhale kupitirira kambirimbiri.
Gawolo likakhala ndi vuto, kuthekera kwa kuwonongeka kwake kumawuka kwambiri. Ngati zigawo zodula zomwe zidagulitsidwa ku PCB, kutayika kumawonjezeka. Chifukwa chake, ndiye zoyipa kwambiri kuti mupeze vuto litasokonekera. Mavuto omwe apezeka nthawi imeneyi nthawi zambiri amayambitsa kugwetsa malonda onse.
Ndi kukonza moyenera ndi makopedwe operekedwa ndi kulondola, ndikofunikira kuti muziyesetsa kuyezetsa m'magawo oyamba. Kupatula apo, ngati bolodi yomaliza italephera, zikwizikwi za zikuluzikulu zimatha kuwonongeka.
