Mukapanga chinthu chamagetsi kapena dera, chimodzi mwazosankha zazikulu zomwe mungakumane nazo ndikusankha mtundu wa bolodi losindikizidwa (PCB) kuti mugwiritse ntchito.Njira ziwiri zodziwika bwino ndi PCB yokhala ndi mbali ziwiri ndi PCB yambali imodzi.Ngakhale onse ali ndi zabwino ndi zoyipa zawo, kusankha koyenera kumatha kupangitsa kuti polojekiti ichitike bwino.Mubulogu iyi, tiwona mozama mawonekedwe a ma PCB a mbali ziwiri ndi ma PCB a mbali imodzi kuti akuthandizeni kupanga chisankho mwanzeru.
PCB yokhala ndi mbali ziwiri.
Ma PCB okhala ndi mbali ziwiri amakhala ndi zingwe zamkuwa ndi zigawo zake mbali zonse za bolodi, zolumikizidwa ndi vias kapena zokutidwa ndi mabowo.Vias izi amachita ngati tunnels conductive, kulola chizindikiro kudutsa zigawo zosiyanasiyana za PCB, kupangitsa kukhala yaying'ono komanso zosunthika.Ma board awa amagwiritsidwa ntchito kwambiri pazida zamagetsi zovuta monga mafoni a m'manja, zida zamakompyuta, komanso kugwiritsa ntchito kwambiri kachulukidwe.
Ubwino wapawiri-mbali PCB.
1. Kuwonjezeka kwapang'onopang'ono kwa zigawo: Ma PCB okhala ndi mbali ziwiri amatha kukhala ndi zigawo zambiri, kupereka mlingo wapamwamba wa magwiridwe antchito mu kukula kophatikizana.Izi ndizofunikira popanga makina ovuta amagetsi.
2. Kupititsa patsogolo luso la mawaya: Pokhala ndi zizindikiro zamkuwa kumbali zonse za bolodi, opanga ali ndi njira zambiri zopangira mawaya, kuchepetsa mwayi wa kusokoneza zizindikiro ndi crosstalk.Izi zimakulitsa kukhulupirika kwa chizindikiro komanso magwiridwe antchito onse.
3. Mtengo Wogwira Ntchito: Ngakhale kuti ndizovuta, ma PCB okhala ndi mbali ziwiri ndi otsika mtengo chifukwa cha kufalikira kwawo komanso kupezeka kwawo.Zitha kupangidwa bwino pamlingo waukulu, kuwapangitsa kukhala njira yabwino pama projekiti akuluakulu.
Zoyipa za PCB yokhala ndi mbali ziwiri
1. Kupanga zovuta: Kuvuta kwa PCB yokhala ndi mbali ziwiri kumapangitsa kuti mapangidwewo akhale ovuta kwambiri, omwe amafunikira mapulogalamu ovuta komanso odziwa zambiri.Izi zimakweza mtengo wa chitukuko chonse cha polojekitiyi.
2. Zovuta za Soldering: Popeza kuti zigawo zilipo kumbali zonse ziwiri, kutsekemera kungakhale kovuta kwambiri, makamaka pazigawo za teknoloji yapamwamba (SMT).Chisamaliro chowonjezereka chimafunika pakusonkhana kuti tipewe maulendo afupiafupi ndi zolakwika.
Single sided PCB
Kumbali inayi, PCB yokhala ndi mbali imodzi ndiyo njira yosavuta kwambiri ya PCB, yokhala ndi zigawo zingapo zamkuwa zomwe zili mbali imodzi yokha ya bolodi.Ma PCB amtunduwu nthawi zambiri amagwiritsidwa ntchito pazinthu zochepa zovuta monga zoseweretsa, zowerengera, ndi zamagetsi zotsika mtengo.
Ubwino wa single-mbali PCB
1. Kupanga kosavuta: Poyerekeza ndi PCB ya mbali ziwiri, PCB ya mbali imodzi ndiyosavuta kupanga.Kuphweka kwa masanjidwewo kumafulumizitsa prototyping ndikuchepetsa nthawi yopanga.
2. Chepetsani ndalama zachitukuko: Ma PCB a mbali imodzi ndi otsika mtengo okhala ndi zigawo zochepa zamkuwa ndi mapangidwe osavuta, kuwapanga kukhala abwino kwa mapulojekiti otsika mtengo kapena mapulojekiti omwe ali ndi zofunikira zochepa zogwirira ntchito.
3. Njira yowotcherera yosavuta: Zigawo zonse zili mbali imodzi, kuwotcherera kumakhala kosavuta, koyenera kwa okonda DIY ndi amateurs.Kuphatikiza apo, kuchepetsa zovuta kumathandizira kuthetsa mavuto.
Zoyipa za PCB ya mbali imodzi
1. Zopinga za Malo: Kuchepetsa kwakukulu kwa ma PCB a mbali imodzi ndi malo ochepa omwe alipo a zigawo ndi njira.Izi zimalepheretsa kugwiritsidwa ntchito kwawo muzinthu zovuta zomwe zimafuna ntchito zapamwamba kapena mawaya ambiri.
2. Kusokoneza kwa chizindikiro: PCB yokhala ndi mbali imodzi ilibe mphamvu yodziyimira payokha ndi yosanjikiza pansi, zomwe zingayambitse kusokoneza kwa chizindikiro ndi phokoso, zomwe zimakhudza ntchito ndi kudalirika kwa dera.
Kusankha pakati pa PCB ya mbali ziwiri ndi PCB ya mbali imodzi kumadalira zovuta ndi zofunikira za polojekiti yamagetsi.Ma PCB a mbali imodzi ndi oyenera kugwiritsa ntchito zosavuta zokhala ndi magwiridwe antchito ochepa, pomwe ma PCB ambali ziwiri amapereka kusinthasintha kwakukulu, kachulukidwe kagawo kakang'ono komanso kuwongolera njira zamachitidwe ovuta kwambiri.Ganizirani zinthu monga mtengo, zofunikira za malo, ndi zolinga zonse za polojekiti kuti mudziwe mtundu woyenera kwambiri wa PCB.Kumbukirani, kufufuza koyenera, kukonzekera, ndi kukambirana ndi katswiri wodziwa kupanga PCB ndizofunikira kwambiri kuti polojekiti yanu ikwaniritsidwe.
