Flexible flat cable (FFC) e phetha karolo ea bohlokoa ho lisebelisoa tsa morao-rao tsa elektronike e le tharollo e ka tšeptjoang haholo le e tenyetsehang ea ho kopanya. Ho ipapisitsoe le boiphihlelo bo sebetsang ba boenjiniere, sengoloa sena se akaretsa lintlha tsa bohlokoa tsa ts'ebeliso ea FFC ho tsoa likarolong tsa khetho, ts'ebetso, ts'ebetso ea ts'epo, le ho rarolla mathata a tloaelehileng, ho fana ka litšupiso bakeng sa basebetsi ba mahlale ba amehang.
I. Litšobotsi tsa Motheo le Lintlha tsa Kgetho tsa Li-FFC
Li-FFC li na le conductor e bataletseng (hangata foil ea koporo), lisebelisoa tsa motheo tse sireletsang metsi (joaloka polyimide (PI) kapa PET), le lera la boikhethelo le sireletsang. Melemo ea bona ea mantlha e mabapi le ho tenyetseha, ho boloka sebaka, le moralo o ikhethileng. Ha u khetha FFC, lintlha tse latelang li lokela ho nahanoa:
Litlhaloso tsa 1.Conductor: Sena se kenyelletsa botenya ba conductor (hangata 9μm, 12μm, 18μm, joalo-joalo) le bophara ba mohala / molumo, tse amang ka ho toba matla a hona joale a ho jara le ts'ebetso ea phetisetso ea matšoao. Lits'ebetso tse phahameng{{6} tsa hajoale li hloka li-conductors tse teteaneng, athe phetiso ea mats'oao a nepahetseng e hloka molumo o fokolang.
2.Insulation Material: Li-substrates tsa PI ha li khone ho mamella mocheso-lithempereichara tse telele- tsa nako e telele li ka fihla ho likhato tse 200 ) 'me li loketse tikoloho e phahameng-. Li-substrates tsa PET li theko e tlase empa li na le khanyetso e tlase ea mocheso (hangata e Ka tlase ho kapa e lekana le likhato tse 105) 'me li loketse lits'ebetso tse akaretsang.
3.Litlhoko tsa Tšireletso: Bakeng sa-maqhubu a maqhubu a phahameng kapa lisebelisoa tse hlokang ts'ebetso e phahameng ea{2}}ea tšitiso, li-FFC tse nang le foil ea aluminium kapa mesh shielding e lohiloeng li ka khethoa ho fokotsa tšitiso ea motlakase (EMI).
4.Flex Life: FFC's bend radius le palo ea li-cycles li lokela ho khethoa ho latela boemo ba sebele ba kopo. Mohlala, likhokahano tse matla (joalo ka meaho ea lihokelo) li hloka -mokhoa oa ho kobeha{3}} o phahameng oa ho hanyetsa.
II. Ho kenya FFC le Taolo ea Ts'ebetso
Mekhoa ea mantlha ea ho kenya FFC e kenyelletsa ho crimping (mohlala, ZIF/non-lihokelo tsa ZIF), soldering (FPC/FFC to PCB soldering), le li-adhesive bonding. Nakong ea ho kenya, lintlha tse latelang tsa bohlokoa li tlameha ho lateloa ka thata:
1. Ho Bapisa Sehokelo: Netefatsa hore molumo oa FFC o lumellana ka botlalo le sehokelo ho qoba ho kopana ho fosahetseng ka lebaka la mamello. Tobetsa-lihokelo tsa fit fit li hloka ho kenngoa ka taolo le matla a ho tlosa ho thibela ho robeha ha conductor.
2.Soldering Process: Haeba u sebelisa SMT mounting, ela hloko profil ea mocheso oa reflow soldering ho qoba substrate delamination kapa pad detachment e bakoang ke mocheso o phahameng. Bakeng sa solder ka letsoho, ho kgothaletswa ho sebedisa-mocheso o tlase (jwalo ka tse nang le Sn-Pb alloys) le ho laola nako ya ho futhumatsa.
3.Securing and Protection: Lits'ebetsong tse matla, li-FFC li lokela ho sireletsoa ka tepi (e kang 3M acrylic tape) kapa likotoana ho thibela ho lokoloha ka lebaka la ho thothomela. Li-FFC tse pepesehileng linthong tsa nako e telele li ka kenngoa ka filimi e sireletsang kapa sheath ho ntlafatsa ho hanyetsa ho apara.
4.Stress Relief: Ho khothaletsoa ho rala litataiso tse kobehileng kapa meaho ea buffer khokahanong lipakeng tsa FFC le PCB e thata ho fokotsa khatello ea maikutlo e kobehang.
III. Tšebeliso ea ho Tšepahala le Mathata a Tloaelehileng a Tharollo
Ho tšepahala ha li-FFC ho ama bophelo ba sesebelisoa ka kotloloho. Mekhoa e tloaelehileng ea ho hloleha e kenyelletsa ho robeha ha conductor, ho senyeha ha insulation, le ho eketseha ha khanyetso ea ho ikopanya. Ho rarolla mathata ana, ho ka nkoa mehato e latelang ea ho ntlafatsa:
1. Ho Thibela Ho robeha ha Conductor: Qoba ho kobeha ho feteletseng, haholo-holo ho radii e nyenyane (e khothalelitsoeng bonyane ba radius E kholo ho feta kapa e lekana le makhetlo a 10 ho feta FFC). Lits'ebetsong tse matla, ho sebelisa-foil ea koporo e nang le ductility e phahameng (joalo ka koporo e rolotsoeng) ho ka ntlafatsa ho kobeha.
2. Mehato ea ho Thibela ho Hloleha ha Insulation: Thibela lintho tse hlabang hore li se ke tsa ngoaea substrate 'me u qobe ho ja ha nako e telele{1}}litikolohong tsa mocheso o phahameng. Bakeng sa{3}lisebelisoa tse phahameng tsa motlakase, etsa bonnete ba hore sebaka sa FFC se fihlang se finyella litekanyetso tsa polokeho.
3. Ho Sebetsana le Mathata a ho Kopana: Kamehla hlahloba lihokelo bakeng sa oxidation, 'me, ha ho hlokahala, sebelisa likhokahano tse nang le khauta- kapa silevera{2}}ho ntlafatsa khanyetso ea oxidation. Bakeng sa ho tobetsa-fit FFCs, etsa bonnete ba hore polaka e notlela ka mokhoa o sireletsehileng ho thibela ho lokoloha.
4. Ho Ikamahanya le Boemo ba Tikoloho: Litikolohong tse mongobo kapa tse senyang, sebelisa li-FFC tse sa keneleng metsi (tse kang tse nang le sekhomaretsi sa UV) kapa -litšila tse thibelang mongobo.
IV. Kakaretso le Outlook
Ka lebaka la libopeho tsa tsona tse bobebe le{0}}mahano a holimo, li-FFC li fetohile karolo ea mantlha ea likhokahano lisebelisoa tsa elektroniki. Lits'ebetsong tse sebetsang, khetho e nepahetseng, mekhoa ea ho kenya, le moralo o ts'epahalang li tlameha ho ikamahanya le maemo a ikhethileng ho eketsa melemo ea ts'ebetso ea bona. Nakong e tlang, ha theknoloji ea elektronike e ntse e tsoela pele, li-FFC li tla tsoela pele ho ikamahanya le maemo (mohlala, moralo o motle oa molumo) le ho ntlafala ha maemo a leholimo (mohlala,{7}}mocheso o phahameng le ho hanyetsa lik'hemik'hale), ho fana ka litharollo tse tšeptjoang tsa khokahanyo bakeng sa libaka tse ntseng li hlaha joalo ka lisebelisoa tse phuthoang le lisebelisoa tsa elektroniki tse aparoang.
Ka boiphihlelo bo hlophisehileng le boits'oaro ba tekheniki, baenjiniere ba ka sebelisa li-FFC ka katleho le ho ntlafatsa ts'ebetso le botsitso ba lihlahisoa tsa bona.
