A boto ea potoloho e hatisitsoeng (PCB) ke boto e tšesaane e entsoeng ka fiberglass, composite epoxy, kapa lisebelisoa tse ling tsa laminate.Li-PCB li fumanoa likarolong tse sa tšoaneng tsa motlakase le tsa elektronike tse kang li-beepers, li-radios, radars, litsamaiso tsa k'homphieutha, joalo-joalo. Mefuta e fapaneng ea PCB e sebelisoa ho latela lits'ebetso.Mefuta e fapaneng ea li-PCB ke efe?Bala pele ho tseba.

Mefuta e fapaneng ea li-PCB ke efe?

Li-PCB hangata li hlophisoa ho ipapisitsoe le makhetlo a mangata, likarolo tse ngata le substrate e sebelisoang.Mefuta e meng e tsebahalang e tšohloa ka tlase.

• Li-PCB tse nang le lehlakore le le leng
  Li-PCB tse nang le lehlakore le le leng ke mofuta oa motheo oa liboto tsa potoloho, tse nang le lera le le leng feela la substrate kapa thepa ea motheo.Lera le koahetsoe ke lera le tšesaane la tšepe, ke hore koporo- e leng mokhanni o motle oa motlakase.Li-PCB tsena li boetse li na le mask a sireletsang solder, a sebelisoang ka holim'a lera la koporo hammoho le seaparo sa skrine sa silika.Melemo e meng e fanoang ke li-PCB tse nang le lehlakore le le leng ke:
  • Li-PCB tse nang le lehlakore le le leng li sebelisetsoa tlhahiso ea molumo 'me li theko e tlaase.
  • Li-PCB tsena li sebelisetsoa lipotoloho tse bonolo tse kang lisensara tsa motlakase, li-relay, li-sensor le lintho tsa ho bapala tsa elektroniki.
• Li-PCB tse nang le mahlakore a mabeli
  Li-PCB tse mahlakoreng a mabeli li na le mahlakore ka bobeli a substrate e nang le lera la conductive la tšepe.Likoti ka boto ea potoloho li lumella likarolo tsa tšepe hore li khomarele ho tloha ka lehlakoreng le leng ho ea ho le leng.Li-PCB tsena li hokahanya lipotoloho ka mahlakoreng ka bobeli ka e 'ngoe ea merero e 'meli e ntseng e hola, e leng theknoloji ea "hole-hole" le thekenoloji ea holim'a metsi.Theknoloji ea ho phunyeletsa ho kenyelletsa ho kenngoa ha likarolo tsa loto ka likoti tse entsoeng pele ho boto ea potoloho, tse rekisoang ho liphahlo ka mahlakoreng a fapaneng.Theknoloji ea holim'a thaba e kenyelletsa likarolo tsa motlakase tse lokelang ho behoa ka ho toba holim'a mapolanka a potoloho.Melemo e fanoang ke li-PCB tse mahlakoreng a mabeli ke:
  • Ho phahamisa holim'a metsi ho lumella lipotoloho tse ngata hore li hoketsoe boto ha ho bapisoa le ho kenngoa ha lesoba.
  • Li-PCB tsena li sebelisoa mefuteng e mengata ea lits'ebetso, ho kenyeletsoa sistimi ea mohala oa selefouno, ho lekola matla, lisebelisoa tsa liteko, li-amplifiers le tse ling tse ngata.
• Li-PCB tse nang le mekhahlelo e mengata
  Multi-lera PCBs ba e hatisitsoeng oa potoloho mapolanka, e leng comprise fetang tse peli magato koporo joaloka 4L, 6L, 8L, joalo-joalo PCBs tsena atolosa thekenoloji sebelisoa ka habeli mahlakoreng a PCB oa.Likarolo tse fapaneng tsa boto ea substrate le lisebelisoa tsa insulating li arola likarolo ho li-PCB tse ngata.Li-PCB li boholo bo kopaneng, 'me li fana ka melemo ea boima le sebaka.Melemo e meng e fanoang ke li-PCB tse nang le mekhahlelo e mengata ke:
  • Li-PCB tse nang le mekhahlelo e mengata li fana ka boemo bo phahameng ba ho feto-fetoha ha moralo.
  • Li-PCB tsena li bapala karolo ea bohlokoa lipotolohong tse lebelo le holimo.Ba fana ka sebaka se eketsehileng bakeng sa mohlala oa conductor le matla.
• Li-PCB tse thata
  Li-PCB tse thata li bua ka mefuta ea li-PCB tseo thepa ea tsona ea motheo e entsoeng ka thepa e tiileng e ke keng ea kobeha.Melemo e meng ea bohlokoa eo ba fanang ka eona:
  • Li-PCB tsena li kopane, tse tiisang hore ho thehoa mefuta e fapaneng ea lipotoloho tse rarahaneng tse potolohileng eona.
  • Li-PCB tse thata li fana ka tokiso le tlhokomelo e bonolo, kaha likarolo tsohle li tšoailoe ka ho hlaka.Hape, litsela tsa lipontšo li hlophisitsoe hantle.
• Li-PCB tse bonolo
  Li-PCB tse bonolo li hahiloe holim'a thepa ea motheo e tenyetsehang.Li-PCB tsena li tla ka liforomo tse nang le lehlakore le le leng, mahlakoreng a mabeli le tse ngata.Sena se thusa ho fokotsa ho rarahana ka har'a kopano ea sesebelisoa.Melemo e meng e fanoang ke li-PCB tsena ke:
  • Li-PCB tsena li thusa ho boloka sebaka se ngata, hammoho le ho fokotsa boima ba boto ka kakaretso.
  • Li-PCB tse feto-fetohang li thusa ho fokotsa boholo ba boto, e leng se etsang hore e be se loketseng bakeng sa lits'ebetso tse fapaneng moo ho hlokahalang matla a mats'oao a holimo.
  • Li-PCB tsena li etselitsoe maemo a ho sebetsa, moo mocheso le boima ba 'mele e leng ntho e amehang haholo.
• Li-Rigid-Flex-PCBs
  Li-PCB tsa flex tse thata ke motsoako oa liboto tsa potoloho tse thata le tse tenyetsehang.Li na le likarolo tse ngata tsa li-circuits tse feto-fetohang tse khomaretsoeng ho feta boto e le 'ngoe e thata.
  • Li-PCB tsena li entsoe ka nepo.Ka hona, e sebelisoa lits'ebetsong tse fapaneng tsa bongaka le tsa sesole.
  • Kaha ke boima bo bobebe, PCB tsena li fana ka 60% ea boima ba 'mele le ho boloka sebaka.
• Li-PCB tsa Maqhubu a Phahameng
  Li-PCB tsa maqhubu a phahameng li sebelisoa sebakeng sa maqhubu a 500MHz - 2GHz.Li-PCB tsena li sebelisoa lits'ebetsong tse fapaneng tsa bohlokoa joalo ka lits'ebetso tsa puisano, li-PCB tsa microwave, li-PCB tsa microstrip, jj.
• Aluminium tšehetso PCBs
  Li-PCB tsena li sebelisoa lits'ebetsong tse phahameng tsa matla, kaha kaho ea aluminium e thusa ho felisa mocheso.Li-PCB tse tšehelitsoeng ke aluminium li tsejoa ka ho fana ka boemo bo phahameng ba ho tiea le boemo bo tlase ba katoloso ea mocheso, e leng se etsang hore e be tse loketseng lits'ebetso tse nang le mamello e phahameng ea mochini.Li-PCB li sebelisetsoa li-LED le lisebelisoa tsa motlakase.

Tlhokahalo ea li-PCB e ntse e eketseha makaleng a fapaneng a indasteri.Kajeno, u tla fumana tse fapa-fapaneng bahlahisi ba tsebahalang ba PCB le baphatlalatsi, ba hlokomelang 'maraka oa lisebelisoa tse hokahantsoeng.Kamehla ho kgothaletswa ho reka PCB bakeng sa tšebeliso ea indasteri le ea khoebo ho tsoa ho baetsi le barekisi ba tsebahalang.Twisted Traces ke bahlahisi ba bang ba tšepahalang le ba nang le boiphihlelo ba mefuta e fapaneng ea li-PCB.Khampani e lula e fa bareki ba eona liboto tsa potoloho tsa boleng bo holimo ka lebelo le holimo, le ts'ebetso.
