Ho theha boto ea potoloho e hatisitsoeng (PCB) ho ka bonahala e le mosebetsi o boima, haholo ho ba qalang. Leha ho le joalo, ka tataiso le tsebo e nepahetseng, mang kapa mang a ka ithuta ho iketsetsa meralo ea PCB ea hae. Tataisong ena ea ba qalang, re tla fana ka litaelo tsa mohato ka mohato mabapi le mokhoa oa ho theha PCB ho tloha qalong. Kahoo, ha re ikakhele ka setotsoana!
Mohato oa 1: Ho rera Moralo oa PCB
Pele o qala ts'ebetso ea nts'etsopele ea PCB, ho bohlokoa ho ba le kutloisiso e hlakileng ea litlhoko tsa projeke ea hau. Fumana sepheo sa PCB, likarolo tseo e tla li tšehetsa, le ts'ebetso e hlokahalang. Theha meralo ho bona ka mahlo a kelello likhokahano tsa potoloho le ho netefatsa moralo o se nang moeli.
Mohato oa 2: Etsa moralo oa PCB
Hang ha schematic e se e lokile, sebopeho sa PCB se ka etsoa. Khetha software e tšepahalang ea moralo oa PCB joalo ka Eagle, Altium Designer kapa KiCad ho rala boto ea hau. Qala ka ho beha likarolo ka leano holim'a boto, ho netefatsa likhokahano tse khutšoane tse ka khonehang. Ela hloko lifofane tsa fatše, tsamaiso ea motlakase, le botšepehi ba lipontšo. Hopola ho boloka sebaka se nepahetseng le ho boloka likarolo tsa bohlokoa li le hole le libaka tse lerata.
Mohato oa 3: Moralo le Trace Placement
Routing e kenyelletsa ho theha mesaletsa ea koporo e hokahanyang likarolo ho PCB. Beha mesaletsa ka tsela e etsang hore lerata le tšitiso ea matšoao li fokotsehe. Kopanya likarolo tse tšoanang 'me u qobe ho tšela mesaletsa ntle le haeba ho hlokahala. Etsa bonnete ba hore ho na le sebaka se nepahetseng pakeng tsa mesaletsa ho thibela li-circuits tse khutšoane. Haeba u sebelisa likarolo tsa holim'a marulelo, etsa bonnete ba hore mesaletsa e tšesaane ho lekana sebaka sa maoto.
Mohato oa Bone: Qetella Moralo
Sheba ka botlalo moralo oa hau oa PCB bakeng sa ho nepahala le ho nepahala. Sheba liphoso leha e le life tsa moralo, likhokahano tse hlokomolohuoang, kapa liphoso tsa ho beha likarolo. Sebelisa sehlahlobi sa melao ea moralo oa software ho tseba mathata a ka bang teng. Ka mor'a hore ntho e 'ngoe le e' ngoe e netefatsoe, lifaele tsa tlhahiso li hlahisoa, ho kenyelletsa le lifaele tsa Gerber le Bill of Materials (BOM), ho netefatsa tlhahiso e nepahetseng ea PCB.
Mohato oa 5: Boqapi le Kopano
Romela moralo oa hau oa ho qetela oa PCB ho moetsi oa khetho ea hau. Litšebeletso tse fapaneng tsa marang-rang tsa PCB tsa marang-rang li fana ka likhetho tse fumanehang bakeng sa ho etsa meralo ea hau. Khetha li-parameter tse loketseng joalo ka thepa ea lakane, palo ea lira le botenya ho latela litlhoko tsa hau. Hang ha PCB ea maiketsetso e phethiloe, laela likarolo tse hlokahalang 'me u qale ho kopanya boto. Etsa bonnete ba hore u latela mekhoa e metle ea soldering ho qoba tšenyo leha e le efe ho likarolo.
Mohato oa 6: Ho etsa liteko le ho rarolla mathata
Ka mor'a hore PCB e kopane, ho bohlokoa ho hlahloba ts'ebetso ea eona. Sebelisa multimeter kapa oscilloscope ho lekola maemo a motlakase, botšepehi ba matšoao le likhokahano tse nepahetseng. Matlafatsa PCB 'me u leke karolo ka 'ngoe. Haeba ho na le mathata a fumanoeng, sebelisa tsebo ea hau ea ho lokisa bothata ho a rarolla le ho lokisa ka nepo.
Ho hlahisa PCB qalong ho ka bonahala e le mokhoa o rarahaneng, empa ka mokhoa o hlophisitsoeng le kutloisiso e nepahetseng, e fetoha mosebetsi o laolehang. Tataiso ena ea ba qalang e fana ka mohato ka mohato oa mokhoa oa ho nts'etsapele PCB ho tloha ho rala moralo ho isa tekong ea tšebetso ea eona. Joalo ka boiphihlelo bofe kapa bofe, boikoetliso le boiphihlelo ba matsoho bo tla ntlafatsa tsebo ea hau ho nts'etsopele ea PCB. Ka hona, kena ka har'a phephetso, 'me u lumelle boqapi ba hau hore bo phalle ho rala li-PCB tse sebetsang hantle. Mahlohonolo!
