Mwachidule, PCB yopanda kanthu imatanthawuza bolodi yosindikizidwa yopanda mabowo kapena zida zamagetsi.Nthawi zambiri amatchedwa ma PCB opanda kanthu ndipo nthawi zina amatchedwanso ma PCB.Gulu la PCB lopanda kanthu limakhala ndi njira zoyambira, mapatani, zokutira zitsulo ndi gawo lapansi la PCB.
Kodi kugwiritsa ntchito PCB board yopanda kanthu ndi chiyani?
PCB yopanda kanthu ndi mafupa a bolodi lachikhalidwe.Imawongolera njira zamakono komanso zamakono kudzera munjira zoyenera ndipo imagwiritsidwa ntchito pazida zamagetsi zambiri zamakompyuta.
Kuphweka kwa PCB yopanda kanthu kumapereka mainjiniya ndi opanga ufulu wokwanira wowonjezera zinthu zina zofunika.Gulu lopanda kanthuli limapereka kusinthasintha komanso limathandizira kupanga zambiri.
PCB board iyi imafuna ntchito yopangira zambiri kuposa njira zina zama waya, koma imatha kukhala yokhayo ikatha kusonkhana ndi kupanga.Izi zimapangitsa ma board a PCB kukhala otsika mtengo komanso abwino kwambiri.
Bolodi lopanda kanthu limangothandiza pambuyo powonjezera zigawo.Cholinga chachikulu cha PCB yopanda kanthu ndikukhala gulu lonse ladera.Ngati ikugwirizana ndi zigawo zoyenera, imakhala ndi ntchito zambiri.
Komabe, izi si ntchito yokhayo anabala PCB matabwa.Blank PCB ndiye siteji yabwino kwambiri yochitira mayeso opanda kanthu pakupanga ma board board.Ndikofunikira kupewa zovuta zambiri zomwe zingachitike mtsogolo.
N'chifukwa chiyani akuyezetsa bolodi?
Pali zifukwa zambiri zoyesera matabwa opanda kanthu.Monga dera bolodi chimango, PCB bolodi kulephera pambuyo unsembe zingayambitse mavuto ambiri.
Ngakhale sizodziwika, PCB yopanda kanthu ikhoza kukhala ndi zolakwika musanawonjezere zigawo.Mavuto omwe amapezeka kwambiri ndi kukomoka, kutsika pang'ono komanso mabowo.Ngakhale zolakwika zazing'ono zimatha kuyambitsa kulephera kupanga.
Chifukwa cha kuchuluka kwa kachulukidwe kazinthu, kufunikira kwa ma board a PCB amitundu yambiri kukupitilirabe, ndikupangitsa kuyesa kwa board kukhala kofunika kwambiri.Pambuyo kusonkhanitsa multilayer PCB, kamodzi kulephera kuchitika, ndi pafupifupi zosatheka kukonza izo.
Ngati PCB yopanda kanthu ndi mafupa a gulu lozungulira, zigawozo ndi ziwalo ndi minofu.Zigawo zimatha kukhala zodula kwambiri ndipo nthawi zambiri zimakhala zovuta, choncho m'kupita kwanthawi, kukhala ndi chimango cholimba kumatha kulepheretsa kuti zigawo zapamwamba ziwonongeke.
Mitundu ya mayeso opanda bolodi
Kodi mungadziwe bwanji ngati PCB yawonongeka?
Izi ziyenera kuyesedwa m'njira ziwiri: zamagetsi ndi kukana.
Mayeso a bolodi opanda kanthu amaganiziranso kudzipatula ndi kupitiriza kwa kugwirizana kwa magetsi.Mayeso odzipatula amayesa kugwirizana pakati pa maulumikizi awiri osiyana, pamene kuyesa kopitilira kumayang'ana kuonetsetsa kuti palibe malo otseguka omwe angasokoneze zamakono.
Ngakhale kuyesa kwamagetsi kumakhala kofala, kuyesa kukana sikozolowereka.Makampani ena adzagwiritsa ntchito kuphatikiza ziwirizi, m'malo mogwiritsa ntchito mwakhungu mayeso amodzi.
Kuyezetsa kukaniza kumatumiza panopa kudzera mwa kondakitala kuti ayese kukana kuyenda.Kulumikizana kwautali kapena kocheperako kumapangitsa kukana kwambiri kuposa kulumikizana kwakufupi kapena kokulirapo.
Mayeso a gulu
Pazinthu zomwe zili ndi projekiti inayake, opanga ma board osindikizidwa nthawi zambiri amagwiritsa ntchito zida zokhazikika poyesa, zomwe zimatchedwa "test racks."Mayesowa amagwiritsa ntchito zikhomo zodzaza masika kuyesa malo aliwonse olumikizana pa PCB.
Mayeso okhazikika okhazikika ndiwothandiza kwambiri ndipo amatha kumaliza m'masekondi ochepa chabe.Choyipa chachikulu ndichokwera mtengo komanso kusowa kwa kusinthasintha.Mapangidwe osiyanasiyana a PCB amafunikira makonzedwe osiyanasiyana ndi mapini (oyenera kupanga zambiri).
Mayeso a Prototype
Mayeso owuluka nthawi zambiri amagwiritsidwa ntchito.Mikono iwiri ya robotic yokhala ndi ndodo imagwiritsa ntchito pulogalamu ya pulogalamu kuyesa kugwirizana kwa bolodi.
Poyerekeza ndi mayeso okhazikika, zimatenga nthawi yayitali, koma ndizotsika mtengo komanso zosinthika.Kuyesa mapangidwe osiyanasiyana ndikosavuta ngati kukweza fayilo yatsopano.
Ubwino wa kuyesa kwa bolodi wopanda kanthu
Kuyesa kwa board board kuli ndi zabwino zambiri, popanda zovuta zazikulu.Njira iyi yopangira zinthu imatha kupewa mavuto ambiri.Kutsika pang'ono kwa ndalama zoyambilira kumatha kupulumutsa ndalama zambiri zokonza ndikusinthanso.
Kuyesa kwa bare board kumathandiza kupeza zovuta kumayambiriro kwa kupanga.Kupeza vuto msanga kumatanthauza kupeza gwero la vutolo ndi kutha kuthetsa vutolo pamiyambi yake.
Ngati vutoli lipezeka munjira yotsatira, zimakhala zovuta kupeza vuto.Pamene bolodi PCB ataphimbidwa ndi zigawo zikuluzikulu, n'zosatheka kudziwa chimene chinayambitsa vuto.Kuyezetsa koyambirira kumathandiza kuthetsa zomwe zimayambitsa.
Kuyesa kumapangitsanso njira yonse kukhala yosavuta.Ngati mavuto apezeka ndikuthetsedwa panthawi yachitukuko cha prototype, magawo otsatirawa amatha kupitilira popanda chopinga.
Sungani nthawi ya polojekiti pogwiritsa ntchito kuyesa kwa board
Pambuyo podziwa kuti bolodi lopanda kanthu ndi chiyani, ndikumvetsetsa kufunikira kwa kuyesa kopanda pake.Mudzapeza kuti ngakhale ndondomeko yoyamba ya polojekitiyi imakhala yochedwa chifukwa cha kuyesedwa, nthawi yopulumutsidwa ndi kuyesa kopanda pake kwa polojekitiyi ndi yochuluka kwambiri kuposa nthawi yomwe imawononga.Kudziwa ngati pali zolakwika mu PCB kungapangitse kuti mavutowo akhale osavuta.
Gawo loyambirira ndi nthawi yotsika mtengo kwambiri yoyesa mayeso opanda kanthu.Ngati gulu ladera lomwe lasonkhanitsidwa likulephera ndipo mukufuna kulikonza pomwepo, mtengo wake ukhoza kukhala wokwera kwambiri.
Gawoli likakhala ndi vuto, kuthekera kwa kusweka kwake kudzakwera kwambiri.Ngati zigawo zamtengo wapatali zagulitsidwa ku PCB, kutayikako kudzawonjezeka.Chifukwa chake, ndizoyipa kwambiri kupeza cholakwika pambuyo poti gulu ladera lisonkhanitsidwa.Mavuto omwe amapezeka panthawiyi nthawi zambiri amachititsa kuti mankhwala onse awonongeke.
Ndi kuwongolera bwino komanso kulondola komwe kumaperekedwa ndi mayesowo, ndikofunikira kuchita mayeso a board opanda kanthu koyambirira kopanga.Kupatula apo, ngati gulu lomaliza ladera likulephera, zigawo zambiri zitha kuonongeka.
