PCB e thata ebile e tenyetseha - litlhaloso tse tsoetseng pele tsa tekheniki

Ka poso ena ea blog, re shebisisa ka botebo lintlha tsa tekheniki tsa li-PCB tse thata-flex le ho hlahloba hore na li fetola lefatše la lisebelisoa tsa elektroniki joang.

Lefapheng le ntseng le tsoela pele la lisebelisoa tsa elektroniki, boqapi bo fetohile motheo oa katleho.Baetsi ba lisebelisoa tsa elektroniki ba lula ba loanela ho ntlafatsa ts'ebetso ea sesebelisoa, ho ntlafatsa ts'ebetso le ho fokotsa boholo.E le ho finyella litlhoko tsena, baenjiniere le baqapi ba retelehela ho theknoloji e tsoetseng pele e bitsoang rigid-flex PCBs.Ho fana ka phetoho e ke keng ea lekanngoa le ho tšepahala, liboto tsena tse tsoetseng pele tsa potoloho li fetotse indasteri ea lisebelisoa tsa elektronike, e leng se etsang hore e be karolo ea bohlokoa ea ntlafatso ea lisebelisoa tsa morao-rao.

Rigid-flex PCB, eo hape e tsejoang e le flex-rigid PCB, e kopanya melemo ea liboto tsa potoloho tse thata le tse tenyetsehang ho ba yuniti e kopaneng.Liboto tsena li entsoe ka li-substrates tse tenyetsehang tse lumellang li-circuitry hore li kobehe, li sothe, 'me li lumellane le lintlha tse fapaneng tsa sebopeho, athe likarolo tse thata li fana ka botsitso le ts'ehetso ea sebopeho ho moralo o akaretsang.Motsoako ona o ikhethang o fana ka tokoloho e ke keng ea lekanngoa ea moralo, e lumellang baenjiniere ho etsa lisebelisoa tseo pele li neng li sa nahane.

E 'ngoe ea lintlha tsa bohlokoa tsa tekheniki ea mapolanka a rigid-flex ke sebopeho sa bona sa mekhahlelo e mengata.Ho fapana le liphanele tsa setso tse thata, tse nang le lera le le leng, liphanele tse thata-thata li ka amohela likarolo tse ngata, tse eketsang haholo menyetla ea moralo.Bokhoni ba ho ba le mekhahlelo e fapaneng libakeng tse fapaneng tsa boto bo lumella tšebeliso e nepahetseng ea sebaka se fumanehang, ho etsa hore li-PCB tse thata-flex li loketse lisebelisoa tse nyane tsa elektroniki.

Sebopeho sa li-multi-layer tsa PCB e tsitsitseng-flex e boetse e thusa ho kopanngoa ha lipotoloho tse rarahaneng.Hona joale lienjiniere li ka kenyelletsa meralo e rarahaneng, joalo ka likhokahano tse phahameng haholo le likarolo tsa molumo o motle, lisebelisoa tsa bona ntle le ho tela ts'ebetso kapa ts'epahalo.Bokhoni bona bo matla bo bula menyetla bakeng sa nts'etsopele ea mahlale a morao-rao a kang liaparo, lisebelisoa tsa bongaka esita le lipontšo tse feto-fetohang.

Ntle le moo, ho tšoarella ha mochini le ho ts'epahala ha li-PCB tse thata-flex li ntle haholo.Li-substrates tse feto-fetohang li entsoe ka thepa ea polyimide, e tsejoang ka botsitso ba eona bo botle ba mocheso, ho hanyetsa lik'hemik'hale le matla a mochine.Sebopeho sena se matsutla-tsutla se thusa li-PCB tse thata hore li khone ho mamella maemo a thata a tikoloho, ho kenyelletsa le mocheso o feteletseng, ho thothomela le ho makala.Ka lebaka leo, lisebelisoa tse sebelisang li-PCB tse thata-thata li ka sebetsa ka mokhoa o se nang sekoli maemong a phephetso, ka hona, li holisa boholo ba lits'ebetso ho pholletsa le liindasteri.

Ho sebelisa li-PCB tse sa fetoheng ho lisebelisoa tsa elektroniki le hona ho ka ntlafatsa botsitso ba matšoao le ho fokotsa tšitiso ea motlakase (EMI).Li-substrates tse feto-fetohang li thusa ho kokobetsa ho thothomela le ho fokotsa tahlehelo ea matšoao, ho netefatsa phetiso e tšepahalang le e sebetsang ea mats'oao a motlakase.Ho phaella moo, li-PCB tse thata-flexible li fana ka tšireletso e phahameng ea EMI, ho fokotsa kotsi ea mahlaseli a motlakase a kenang ho kena-kenana le likarolo tse haufi kapa ho ama ts'ebetso ea kakaretso ea sesebelisoa.Sena se etsa hore li-PCB tse thata-thata e be tse loketseng lits'ebetso tsa maqhubu a holimo joalo ka litsamaiso tsa puisano tse se nang mohala le lisebelisoa tsa elektroniki tsa likoloi.

Li-PCB tse thata-flex ha li ntlafatse ts'ebetso le ts'epahalo ea lisebelisoa tsa elektronike, empa hape li thusa ho boloka litšenyehelo nakong ea ts'ebetso ea tlhahiso.Ho kopanya mesebetsi e mengata letlapeng le le leng ho fokotsa tlhokahalo ea likarolo tse eketsehileng le ho nolofatsa kopano, kahoo ho fokotsa litšenyehelo tsa tlhahiso le ho eketsa tlhahiso.Ho feta moo, sebopeho sa komporo ea li-PCB tse thata-flex e lumella mehato e menyenyane ea lisebelisoa, ho boloka thepa le litšenyehelo tsa ho paka.

Ka kakaretso, Li-PCB tse thata tse feto-fetohang li fetotse lefatše la lisebelisoa tsa elektroniki ka ho fana ka litlhaloso tse tsoetseng pele tsa tekheniki tse fihlelang litlhoko tsa lisebelisoa tsa sejoale-joale.Liboto tsena tsa potoloho tse feto-fetohang le tse tšepahalang li fana ka phetoho ea moralo, kaho ea mekhahlelo e mengata, ho tšoarella ha mochini, ho ntlafala ha ponts'o ea matšoao, ho fokotsa EMI le ho boloka litšenyehelo.Ka ho sebelisa li-PCB tse sa fetoheng, baenjiniere le bahlahisi ba ka sutumelletsa meeli ea boqapi le ho fana ka mahlale a atlehileng 'marakeng.Ha indasteri ea lisebelisoa tsa elektroniki e ntse e tsoela pele ho fetoha, ho hlakile hore li-PCB tse sa fetoheng li tla bapala karolo ea bohlokoa ho bopeng bokamoso ba lisebelisoa tsa elektroniki.
