Lefatšeng la kajeno le potlakileng, theknoloji e ntse e tsoela pele ka lebelo le potlakileng, e ama karolo e 'ngoe le e 'ngoe ea bophelo ba rona ba letsatsi le letsatsi.E 'ngoe ea tsoelo-pele e joalo ke botumo bo ntseng bo hola ba limithara tse bohlale, tse fanang ka melemo e mengata mabapi le ts'ebeliso ea matla le ho lekola nako ea nnete.Empa ke eng e kenang tlhahisong ea lisebelisoa tsee tse ncha?Karabo e tseleng e rarahaneng ea kopano ea PCB ea mithara e bohlale.
Kopano ea PCB, kapa kopano ea boto ea potoloho e hatisitsoeng, ke motheo oo ho oona ho hahoang limithara tse bohlale le mefuta e mengata ea lisebelisoa tsa elektroniki.Li-PCB li sebetsa e le sethala sa khokahanyo bakeng sa likarolo tsohle tsa elektroniki ka har'a sesebelisoa, se lumellang puisano e se nang moeli le ts'ebetso.Ha ho tluoa tabeng ea limithara tse bohlale, ho rarahana ha kopano ea PCB ho bohlokoa le ho feta, kaha lisebelisoa tsena li hloka ho nepahala le bokhoni ba ho sebetsa ka katleho ho lekola tšebeliso ea matla.
Ts'ebetso ea ho kopanya ea mitha e bohlale PCB e qala ka khetho ea lisebelisoa tsa boleng bo holimo tse fihlelang litlhoko tse ikhethang tsa ho tšoarella, ho tsamaisa le taolo ea mocheso.Sena se bohlokoa ho netefatsa ho ts'epahala le bophelo bo bolelele ba metara e bohlale.Hang ha lisebelisoa li khethiloe, ts'ebetso ea kopano ea PCB e fetela pele ho behoa ha lisebelisoa tsa holim'a metsi, tse kang li-resistors, li-capacitor, le li-circuits tse kopantsoeng, ho sebelisa mechine ea morao-rao ea ho khetha le ho beha sebaka.Ho nepahala ke ntho e ka sehloohong mona, kaha phoso leha e le efe kapa phoso e ka senya ts'ebetso ea meter e bohlale.
Ka mor'a hore likarolo tsa holim'a thaba li be teng, kopano ea PCB e tsoela pele ka mokhoa oa ho kopanya, moo likarolo li kenngoa ka mokhoa o sireletsehileng ho boto.Sena se finyelloa ka mekhoa ea ho solder kapa ea reflow soldering, eo ka bobeli e hlokang taolo e nepahetseng ea mocheso ho theha likhokahano tse matla le tse tšepahalang.Hang ha solder e felile, PCB ea mitha e bohlale e ea hlahlojoa le ho hlahlojoa ka botlalo ho netefatsa hore likarolo tsohle li sebetsa kamoo li reriloeng.
Ntle le likarolo tsa tekheniki tsa kopano ea PCB ea mitha e bohlale, ts'ebetso ea tlhahiso e boetse e kenyelletsa ho latela melao le melaoana ea indasteri.Ho latela maemo ana ho bohlokoa haholo ho netefatseng polokeho le ts'ebetso ea limithara tse bohlale.Ho feta moo, menahano ea tikoloho e tlameha ho tsotelloa, ho totobatsoe tšebeliso ea thepa e bolokang tikoloho le mekhoa ea tlhahiso.
Bohlokoa ba kopano ea PCB ea metara e bohlale bo fetela ka nģ'ane ho mohato oa tlhahiso, kaha o bapala karolo ea bohlokoa ho bopa bokamoso ba tsamaiso ea matla.Limithara tse bohlale li fa bareki bokhoni ba ho lekola tšebeliso ea bona ea matla ka nako ea 'nete, e ba fa matla a ho etsa liqeto tse nepahetseng mabapi le mekhoa ea bona ea ho e sebelisa.Ho feta moo, lisebelisoa tsena li thusa tsamaiso e ntle ea grid bakeng sa bafani ba lisebelisoa, e lebisang ho ntlafatseng ts'ebetso le ho fokotsa litšila.
Ha thekenoloji e ntse e tsoela pele ho fetoha, tlhoko ea limithara tse bohlale le li-PCB tse amanang le tsona e tla tsoela pele ho hola.Ka kutloisiso ea ho rarahana ho amehang kopanong ea PCB ea mitha e bohlale, re fumana kananelo e tebileng bakeng sa boqapi bo hlokolosi le boqapi bo kenang ho theheng lisebelisoa tsena tse fetolang.Qetellong, limithara tse bohlale li emela khetho e bohlale bakeng sa bokamoso bo tsitsitseng le bo hokahaneng ba matla, 'me ho nepahala ha kopano ea PCB ho ka pelong ea tsona kaofela.
