ThePulogalamu ya PCBakusintha nthawi zonse ndi kupita patsogolo kwa luso ndondomeko, koma mfundo, wathunthu PCB dera bolodi ayenera kusindikiza bolodi dera, ndiye kudula bolodi dera, pokonza mkuwa atavala laminate, kusamutsa bolodi dera, dzimbiri, kubowola, pretreatment, ndipo kuwotcherera kumatha kuyatsidwa pambuyo popanga izi.Zotsatirazi ndikumvetsetsa kwatsatanetsatane kwa njira yopangira bolodi ya PCB.
Pangani chojambula chojambula molingana ndi ntchito ya dera.Mapangidwe a chithunzi chojambula amachokera makamaka pamagetsi a gawo lililonse kuti apangidwe moyenera ngati pakufunika.Chithunzicho chikhoza kuwonetsa bwino ntchito zofunika za bolodi la dera la PCB ndi mgwirizano pakati pa zigawo zosiyanasiyana.Mapangidwe a chithunzi chojambula ndi sitepe yoyamba pakupanga kwa PCB, ndipo ndi sitepe yofunika kwambiri.Nthawi zambiri mapulogalamu omwe amagwiritsidwa ntchito popanga ma schematics ozungulira ndi PROTEl.
Pambuyo pomaliza kukonza, ndikofunikira kupititsa patsogolo gawo lililonse kudzera mu PROTEL kuti mupange ndikuzindikira gululi ndi mawonekedwe ofanana ndi kukula kwa zigawo.Pambuyo pakusintha phukusi lachigawo, yesani Sinthani/Set Preference/pin 1 kuti muyike malo ofotokozera phukusi pa pini yoyamba.Kenako yesani cheke cha Report/Component Rule kuti muyike malamulo onse kuti awonedwe, ndipo OK.Panthawiyi, phukusi limakhazikitsidwa.
Pangani PCB yoyambira.Ukonde ukapangidwa, malo a gawo lililonse ayenera kuyikidwa molingana ndi kukula kwa gulu la PCB, ndipo ndikofunikira kuwonetsetsa kuti zitsogozo za gawo lililonse siziwoloka poyika.Pambuyo kuyika kwa zigawo zamalizidwa, DRC kuyendera potsiriza ikuchitika kuthetsa pini kapena kutsogolera kuwoloka zolakwa za chigawo chilichonse pa mawaya.Pamene zolakwa zonse kuthetsedwa, wathunthu pcb kapangidwe ndondomeko anamaliza.
Sindikizani bolodi yozungulira: Sindikizani bolodi yokokedwa ndi pepala losamutsa, tcherani khutu ku mbali yoterera yomwe ikuyang'anizana, nthawi zambiri sindikizani matabwa awiri, ndiko kuti, sindikizani matabwa awiri papepala limodzi.Pakati pawo, sankhani yomwe ili ndi zotsatira zabwino kwambiri zosindikizira kuti mupange bolodi la dera.
Dulani laminate yamkuwa, ndipo gwiritsani ntchito mbale ya photosensitive kuti mupange chithunzi chonse cha bolodi la dera.Ma laminates okhala ndi mkuwa, ndiye kuti, matabwa ozungulira ophimbidwa ndi filimu yamkuwa kumbali zonse ziwiri, amadula ma laminates okhala ndi mkuwa kukula kwa bolodi la dera, osati lalikulu kwambiri, kuti apulumutse zipangizo.
Kukonzekera kwazitsulo zamkuwa: gwiritsani ntchito sandpaper yabwino kuti mupukutire zitsulo za oxide pamtunda wa laminates zokhala ndi mkuwa kuti zitsimikizire kuti tona pa pepala lotengera kutentha likhoza kusindikizidwa mwamphamvu pazitsulo zamkuwa pamene mukusamutsa bolodi.Kumaliza kowala popanda madontho owoneka.
Tumizani bolodi losindikizidwa: Dulani bolodi losindikizidwa mu kukula koyenera, muyike mbali yosindikizidwa yozungulira pa laminate yamkuwa, mutatha kuyanjanitsa, ikani laminate yamkuwa mu makina otengera kutentha, ndikuonetsetsa kuti mukuyiyika mu Pepala. sichinasinthidwe molakwika.Nthawi zambiri, pambuyo pa kusamutsidwa kwa 2-3, bolodi yozungulira imatha kusamutsidwa mwamphamvu ku laminate yamkuwa.Makina osinthira kutentha adatenthedwa pasadakhale, ndipo kutentha kumayikidwa pa 160-200 digiri Celsius.Chifukwa cha kutentha kwambiri, chonde tcherani khutu ku chitetezo pamene mukugwira ntchito!
Gulu lozungulira la Corrosion, reflow soldering makina: choyamba fufuzani ngati kusamutsidwa kwatha pa bolodi la dera, ngati pali malo ochepa omwe sanasamutsidwe bwino, mungagwiritse ntchito cholembera chakuda chopangira mafuta kuti mukonze.Ndiye akhoza dzimbiri.Pamene filimu yamkuwa ikuwonekera pa bolodi la dera lawonongeka kwathunthu, bolodi la dera limachotsedwa kumadzi owononga ndikutsukidwa, kotero kuti bolodi lozungulira liwonongeke.The zikuchokera njira zikuwononga ndi anaikira hydrochloric asidi, anaikira wa hydrogen peroxide, ndi madzi chiŵerengero cha 1:2:3.Pokonzekera njira zowononga, onjezerani madzi poyamba, kenaka yikani hydrochloric acid ndi hydrogen peroxide.Ngati concentrated hydrochloric acid, moyikira wa hydrogen peroxide kapena corrosive solution satero Samalani kuwaza pakhungu kapena zovala ndikutsuka ndi madzi oyera pakapita nthawi.Popeza njira yamphamvu yakuwononga imagwiritsidwa ntchito, onetsetsani kuti mwatcheru chitetezo mukamagwira ntchito!
Kubowola kwa bolodi: Gulu loyang'anira dera ndikuyika zida zamagetsi, kotero ndikofunikira kubowola bolodi lozungulira.Sankhani zobowola zosiyanasiyana molingana ndi makulidwe a zikhomo zamagetsi zamagetsi.Pogwiritsa ntchito kubowola pobowola mabowo, bolodi lozungulira liyenera kupanikizidwa mwamphamvu.Liwiro la kubowola sikuyenera kukhala pang'onopang'ono.Chonde yang'anani wogwiritsa ntchito mosamala.
Circuit board pretreatment: Mukamaliza kubowola, gwiritsani ntchito sandpaper yabwino kwambiri popukuta tona yomwe imaphimba bolodi lozungulira, ndikuyeretsa bolodi ndi madzi oyera.Madzi akauma, perekani madzi a pine kumbali ndi dera.Kuti tifulumizitse kulimba kwa rosin, timagwiritsa ntchito chowotcha mpweya wotentha kuti tiwotche bolodi la dera, ndipo rosin imatha kulimba mu mphindi 2-3 zokha.
Zida zamagetsi zowotcherera: Ntchito yowotcherera ikamalizidwa, chitani mayeso athunthu pagulu lonse ladera.Ngati pali vuto panthawi yoyesedwa, m'pofunika kudziwa malo a vutolo kudzera mu chithunzi cha schematic chopangidwa mu sitepe yoyamba, ndiyeno bwereraninso kugulitsa kapena kusintha chigawocho.chipangizo.Pamene mayeso adutsa bwino, bolodi lonse la dera latha.
