M'magawo a PCB, akatswiri ambiri opanga zamagetsi sadziwa kwenikweni kuti ndi mafayilo amtundu wanji omwe amafunikira komanso momwe angapangire mafayilo oyenerera kuti asonkhane pamwamba.Tikudziwitsani zonse za izi.Fayilo ya data ya Centroid.
Deta ya Centroid ndi fayilo yamakina yomwe ili mumtundu wa ASCII wokhala ndi wojambula, X, Y, kuzungulira, pamwamba kapena pansi pa bolodi.Deta iyi imathandizira mainjiniya athu kuti apitilize kusonkhanitsa ma mount mount m'njira yolondola.
Kuyika magawo okwera pamwamba pa ma PCB kudzera pazida zokha, ndikofunikira kupanga fayilo ya Centroid kuti ikonzekere zida.Fayilo ya Centroid imakhala ndi magawo onse kuti makina azidziwa komwe angayike gawo komanso momwe PCB imayendera.
Fayilo ya Centroid imakhala ndi izi:
1. Reference Designator (RefDes).
2. Gulu.
3. X malo.
4. Y malo.
5. Njira Yozungulira.
RefDes
RefDes imayimira wolemba wotsogolera.Idzagwirizana ndi bilu yanu yazinthu ndi mawonekedwe a PCB.
Gulu
Layer amatanthauza kumtunda kapena kuseri kwa PCB kapena mbali yomwe zigawozo zimayikidwa.Opanga PCB ndi ophatikiza nthawi zambiri amatcha pamwamba ndi kumbuyo mbali mbali ya gawo ndi solder, motsatana.
Malo
Malo: Malo a X ndi Y amatanthawuza zikhalidwe zomwe zimazindikiritsa malo opingasa ndi oyima a gawo la PCB potengera komwe board idachokera.
Malo amayezedwa kuyambira pomwe adayambira mpaka pakati pa gawolo.
Magwero a bolodi amatanthauzidwa ngati (0, 0) mtengo ndipo ali kumunsi kumanzere kwa bolodi kuchokera pamwamba.
Ngakhale mbali yakumbuyo ya bolodi imagwiritsa ntchito ngodya yakumanzere yakumanzere ngati malo oyambira.
Miyezo ya malo a X ndi Y imayesedwa kufika pa gawo limodzi mwa magawo khumi a inchi (0.000).
Kasinthasintha
Kuzungulira ndi komwe kumazungulira kwa gawo la PCB lomwe limatchulidwa pamwamba.
Kuzungulirako ndi mtengo wa 0 mpaka 360 kuchokera komwe unayambira.Mbali zonse zapamwamba ndi zosungirako zimagwiritsa ntchito malo apamwamba monga malo awo ofotokozera.
Zotsatirazi ndi njira zazikulu zopangira izo ndi mapulogalamu osiyanasiyana opangira
Pulogalamu ya Eagle
1. Thamangani mountsmd.ulp kupanga fayilo ya Centroid.
Mutha kuwona fayiloyo popita ku menyu.Sankhani Fayilo ndikuyendetsa ULP kuchokera pamndandanda wotsitsa.Pulogalamuyo idzapanga mwamsanga .mnt (mount top) ndi .mnb (mount reverse).
Fayiloyi imasunga malo a zigawozo komanso makonzedwe a chiyambi cha PCB.Fayiloyo ili mumtundu wa txt.
Pulogalamu ya Altium
Pulogalamuyi imagwiritsidwa ntchito kupanga chosankha ndikuyika zomwe zidzagwiritsidwe ntchito pakusokonekera.
Pali njira ziwiri zopangira zotulutsa:
1. Pangani Fayilo Yosinthira Ntchito Yotulutsa (*.outjob).Izi adzalenga bwino kukhazikitsidwa linanena bungwe jenereta.
2. Kuchokera menyu kusankha Fayilo.Ndiye kuchokera dropdown mndandanda, alemba pa Assembly linanena bungwe ndiyeno Amatulutsa Sankhani ndi Place owona.
Pambuyo kuwonekera, Chabwino, mudzaona linanena bungwe Sankhani ndi Place Setup kukambirana bokosi.
Zindikirani: Zomwe zimapangidwa ndi fayilo ya Output Job Configuration ndizosiyana ndi zomwe zinapangidwa ndi bokosi la zokambirana la Pick and Place Setup.Zokonda zimasungidwa mufayilo yosinthira mukamagwiritsa ntchito fayilo ya Output Job Configuration.Komabe, mukamagwiritsa ntchito bokosi la Pick and Place Setup, zosintha zimasungidwa mufayilo ya polojekiti.
