Lefatšeng la lisebelisoa tsa elektronike tse ntseng li tsoela pele ka potlako, tlhokahalo ea lisebelisoa tse kopanetsoeng, tse bobebe le tse sebetsang hantle haholo li lebisitse ho amoheloeng hohle ha li-PCB tse thata-fetohang (Printed Circuit PCBs). Liboto tsena tse ncha tsa potoloho li kopanya likarolo tse ntle tsa li-PCB tse thata le tse tenyetsehang ho fana ka ts'epo le ts'ebetso e ntlafalitsoeng. Leha ho le joalo, ho rala li-PCB tse thata-thata ho hloka hore ho nahanoe ka hloko lintlha tse fapaneng ho netefatsa botšepehi bo nepahetseng ba matšoao, tsamaiso ea mocheso le matla a mochine. Sengoliloeng sena se hlahloba lintlha tsa bohlokoa ha ho etsoa meralo ea PCB e thata, e shebaneng le botenya ba lera, palo ea likarolo, melao ea moralo, kopano le liteko.
Botenya ba lera le palo ea lihlopha
E 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa tsa moralo o thata-flex laminate ke ho khetholla botenya bo nepahetseng ba lera le palo ea lihlopha. Botenya ba lera le leng le le leng le ama ka kotloloho ts'ebetso le ts'epahalo ea PCB. Mekhahlelo e metenya e fana ka matla a ntlafetseng a mochini le taolo ea mocheso, athe tse tšesaane li ntlafatsa ho tenyetseha le ho fokotsa boima ba 'mele.
Ha ho etsoa li-PCB tse thata-flex, ho tlameha ho ba le tekano lipakeng tsa lintlha tsena. Multi-layer stacking e ka ntlafatsa botšepehi ba matšoao ka ho fana ka tšireletso e betere le ho fokotsa tšitiso ea motlakase (EMI). Leha ho le joalo, ho eketsa palo ea li-layers ho thatafatsa ts'ebetso ea tlhahiso mme ho ka baka litšenyehelo tse phahameng. Ka hona, baqapi ba tlameha ho lekola ka hloko litlhoko tse khethehileng tsa kopo ho fumana hore na tlhophiso e nepahetseng ea lera e tla ba efe.
Litlhokomelo tsa botšepehi ba pontšo
Botšepehi ba pontšo bo bohlokoa ho moralo o thata oa PCB, haholo lits'ebetsong tsa lebelo le holimo. Sebopeho sa PCB se tlameha ho fokotsa tahlehelo ea lets'oao le ho khopama, tse ka fihlellehang ka ho tsamaisa ka hloko le ho phutha lera. Baqapi ba lokela ho nahana ka lintlha tse latelang ho matlafatsa botšepehi ba matšoao:
Taolo ea Impedans:Ho boloka impedance e tsitsitseng ho pholletsa le PCB eohle ho bohlokoa ho fokotsa maikutlo le ho netefatsa botšepehi ba matšoao. Sena se ka finyelloa ka ho laola bophara ba mesaletsa le sebaka pakeng tsa mesaletsa.
Lifofane tsa fatše le tsa Matla:Ho sebelisa lifofane tse inehetseng tsa fatše le matla ho thusa ho fokotsa lerata le ho ntlafatsa botšepehi ba matšoao. Lifofane tsena li fana ka tsela e fokolang ea ho khutlela morao, e leng ea bohlokoa bakeng sa lipontšo tsa lebelo le phahameng.
Ka Sebopeho:The peakanyo le mofuta oa vias sebelisoa ka moralo ka haholo ama pontšo botšepehi. Li-vias tse foufetseng le tse patiloeng li thusa ho khutsufatsa bolelele ba tsela ea matšoao le ho fokotsa ho kenya letsoho, ha ho behoa ka hloko ho ka thibela crosstalk pakeng tsa litsela tse haufi.
Melao ea moralo e lokelang ho lateloa
Ho khomarela melao e hlophisitsoeng ea moralo ho bohlokoa ho netefatsa ho tšepahala ha li-PCB tse thata-flex. Melao e meng ea bohlokoa ea moralo e lokelang ho nahanoa e kenyelletsa:
Minimum Aperture:Bonyane aperture size bakeng sa vias le pads lokela ho hlalosoa e thehiloeng bokgoni tlhahiso. Sena se etsa bonnete ba hore li-PCB li ka hlahisoa ka mokhoa o tšepahalang le ntle le liphoso.
Bophara ba mola le sebaka:Bophara le sebaka sa mesaletsa se tlameha ho baloa ka hloko ho thibela mathata a kang li-circuits tse khutšoane le ho fokotsa matšoao. Baqapi ba lokela ho sheba maemo a IPC bakeng sa tataiso mabapi le bonyane ba bophara ba mela le sebaka.
Taolo ea Thermal:Taolo e nepahetseng ea mocheso e bohlokoa ho boloka ts'ebetso le ts'epahalo ea li-PCB tse thata-flex. Baqapi ba lokela ho nahana ka li-vias tsa mocheso le lisinki tsa mocheso ho felisa mocheso o hlahisoang ke likarolo tse phahameng tsa matla.
Sengoloa sa kopano le tlhahlobo
Ts'ebetso ea ho kopanya ea li-PCB tse thata-thata e hlahisa liphephetso tse ikhethang tse tlamehang ho rarolloa nakong ea moralo. Ho etsa bonnete ba hore mokhoa oa ho kopanya o boreleli, baqapi ba lokela ho:
Behela sebaka sa sehokelo:Sebaka se lekaneng se lokela ho bolokeloa lihokelo le likarolo tse ling ho tsamaisa kopano le tlhokomelo. Sena se bohlokoa ka ho khetheha meralong e kopaneng moo sebaka se lekanyelitsoeng.
Sebopeho sa Ntlha ea Teko:Ho kenyelletsa lintlha tsa tlhahlobo moralong ho etsa hore liteko le ho rarolla mathata ho be bonolo nakong ea kopano. Baqapi ba lokela ho beha lintlha tsa tlhahlobo ka mokhoa o hlophisehileng ho netefatsa phihlello ntle le ho ama sebopeho ka kakaretso.
Flexibility le ho Kobeha Radius:Moralo o tlameha ho nahana ka ho tenyetseha ha PCB, haholo libakeng tseo ho kobehang ho tla etsahala. Baqapi ba lokela ho khomarela radius e khothalelitsoeng ho thibela tšenyo ea PCB nakong ea tšebeliso.
Ho khonahala ha ts'ebetso ea tlhahiso ea PCB e thata-flex
Qetellong, ho khonahala ha ts'ebetso ea tlhahiso ea PCB e thata-flex e tlameha ho nahanoa nakong ea moralo. Ho rarahana ha moralo ho ama bokhoni ba tlhahiso le litšenyehelo. Baqapi ba lokela ho sebelisana haufi-ufi le moetsi oa PCB ho etsa bonnete ba hore moralo o ka hlahisoa ka katleho le ka har'a tekanyetso.
Ka kakaretso, ho rala li-PCB tse thata-thata ho hloka kutloisiso e felletseng ea lintlha tse amang ho ts'epahala le ts'ebetso. Ka ho ela hloko ka hloko botenya ba lera, botšepehi ba matšoao, melao ea moralo, le litlhoko tsa kopano le tlhahlobo, baqapi ba ka etsa li-PCB tse sa fetoheng tse fihlelang litlhoko tsa lits'ebetso tsa sejoale-joale tsa elektroniki. Ha thekenoloji e ntse e tsoela pele, li-PCB tse sa fetoheng li tla hola ka bohlokoa indastering ea lisebelisoa tsa elektroniki, kahoo baqapi ba tlameha ho lula ba tseba ka mekhoa e metle le mekhoa e hlahang moralong oa PCB.
