Melemo ea Flexible PCB le Rigid-Flex PCB

Ho ea ka maemo a IPC 6013, liboto tse feto-fetohang li arotsoe ka liboto tse nang le lehlakore le le leng, mahlakoreng a mabeli, a mangata, le a thata-thata.

Mokhoa oa ho etsa mapolanka a thata-thata o kenyelletsa ho lokisoa ha thepa, ho etsa, ho cheka, ho cheka, ho pata, ho seha boto, le tlhahlobo ea motlakase.

Ts'ebetso ea ho etsa liboto tse thata-thata ke khetho e nepahetseng bakeng sa ho aha lipotoloho indastering ea bongaka, ea sefofane, ea sesole le ea mehala.

Ka lebaka la melemo ea tsona e kang bobebe, ho ba le bongata bo boholo ba kopano, le ho ba le li-miniaturization, tlhoko ea li-PCB tse joalo e ntse e eketseha. Li-PCB tse feto-fetohang le tsona li na le moralo o tsoetseng pele oa mechini le ts'ebetso e ntle ea motlakase le mocheso. Botumo ba li-PCB tse feto-fetohang bo susumelitse nts'etsopele ea lihlahisoa tse ling tse amanang le tsona, joalo ka li-PCB tse feto-fetohang tsa HDI, li-PCB tse feto-fetohang tse kentsoeng, le li-PCB tse thata tse feto-fetohang.

Har'a lihlahisoa tsena tse nkiloeng ho tsona, li-PCB tse thata li sebelisoa haholo indastering ea likoloi, ea bongaka, ea sesole le ea lifofane. Ho etsoa ha liboto tse thata ke ts'ebetso e jang nako e ngata, e kenyeletsang mehato e kang ho lokisa thepa, ho ebola, ho cheka le ho poleiti, ho lateloa ke tlhahiso ea lihlahisoa tsa ho qetela. Tataiso ena e tla hlahloba li-PCB tse tenyetsehang le ho utloisisa ts'ebetso ea tlhahiso ea thata.

Flexible PCBs Melemo

Boto ea potoloho e entsoeng ka lisebelisoa tsa motheo tse tenyetsehang e bitsoa PCB e tenyetsehang. Li-PCB tse feto-fetohang (kapa liboto tse feto-fetohang) lia tenyetseha le maemo, li khona ho bōptjoa ho fihlela litlhoko tsa mefuta e fapaneng ea likopo. Ha ho bapisoa le liboto tse thata tsa setso, liboto tsa flex li na le melemo e mengata, ho kenyelletsa:

• Boholo bo nyane, bo bobebe
• Bohlanya
• Miniaturization ea lipotoloho, bongata ba kopano e phahameng
• Liphoso tse fokolang tsa lithapo
• Ho feto-fetoha ha maemo, ho loketse ho aha lipotoloho tse kobehang
• Ha ho hlokahale lihokelo tsa mochini
• E lumellana le likhokahano tsa 3D
• Tekanyo e phahameng ea tokoloho ea moralo oa mochini le oa elektroniki
• Botšepehi bo phahameng ba pontšo le botšepehi ba potoloho
• Taolo e ntle ea impedance
• Mefuta e mengata ea mocheso oa ho sebetsa
• Khanyetso e matla ya tshohanyetso
• E loketse libaka tse thata

Leha a na le melemo ena kaofela, li-PCB tse tenyetsehang li na le litšenyehelo tse phahameng tsa thepa ha li bapisoa le liboto tse thata kapa tse thata. Liboto tse thata-thata li kopanya melemo ea li-PCB tse thata le tse tenyetsehang, e leng se etsang hore e be thuso bakeng sa tlhahiso ea potoloho. Litaba tse latelang li tla hlahisa mapolanka a thata-thata le mokhoa oa ho etsa lintho tse thata.

Li-Rigid-flex board li sebelisoa hangata indastering ea likoloi, tsa bongaka, tsa sesole le tsa lifofane.

Li-Rigid-Flexible Boards ke eng

Ho latela maemo a IPC 6013, liboto tse feto-fetohang li arotsoe ka mefuta e fapaneng, ho kenyeletsoa mapolanka a mahlakoreng a le mong, a mahlakore a mabeli, a mangata, le a thata-thata. Mofuta oa 4 tlas'a IPC 6013 o bua ka mapolanka a thata-thata, a kopanyang melemo ea liboto tse tenyetsehang le tse thata. Li ka hlalosoa e le liboto tsa lebasetere kapa mapolanka a thata-thata. Li-Rigid-flex board li arotsoe ka mekhahlelo e 'meli:

1. Flexible Mounting Type - Mofuta ona o ka kobeha hanngoe feela nakong ea ho kenya kapa ho e lokisa.
2. Dynamic Flexible Type - Mofuta ona o ka kobeha hangata ha o sebelisoa.

Mapolanka a Rigid-flex a loketse likopo tse hlokang boholo bo fokolang, ke hore, tlhokahalo ea ho kenyelletsa likarolo tse ngata sebakeng se senyenyane. E entsoe sebakeng sa 3D, mapolanka a thata-thata a na le bokhoni bo phahameng ba sebaka; li ka kobeha kapa tsa menwa ka matla, tsa nolofatsa ho thehwa ha sebopeho se hlokehang sephuthelong sa ho qetela sa sehlahiswa; ha li hloke likhokahano tse ngata, li hloka tlhokomelo e fokolang, 'me li tsejoa ka bophara bakeng sa ho tšepahala ha tsona; mapolanka a rigid-flex a sebelisoa haholo indastering ea bongaka, ea mehala le ea sefofane.

Mapolanka a Rigid-flex a loketse likopo tse hlokang boholo bo fokolang, ke hore, tlhokahalo ea ho kenyelletsa likarolo tse ngata sebakeng se senyenyane.

Mokhoa oa Tlhahiso oa Rigid-flex

Pele ts'ebetso ea tlhahiso e sa fetoheng e qala, moralo oa moralo oa PCB o tlameha ho etsoa. Hang ha moralo o khethiloe, ts'ebetso ea tlhahiso e thata-flex e ka qala.

Mokhoa o thata oa ho etsa lintho o kopanya mekhoa ea ho etsa liboto tse thata le tse tenyetsehang. Liboto tse thata-thata li bokella li-PCB tse thata le tse tenyetsehang ka sekhahla. Likarolo li bokelloa libakeng tse thata 'me li hokahane le liboto tse thata tse haufi ka libaka tse tenyetsehang. Likamano pakeng tsa lihlopha li hlahisoa ka likoti tse phunyeletsoeng.

Ts'ebetso ea tlhahiso ea rigid-flex e kenyelletsa mehato e latelang:

1. Lokisetsa substrate: Mohato oa pele oa mokhoa o tsitsitseng oa ho etsa lintho ke ho lokisa kapa ho hloekisa laminate. Ho sa tsotellehe hore na ho na le sekhomaretsi sa sekhomaretsi, li-laminate tse nang le likarolo tsa koporo li lokela ho hloekisoa pele li kenngoa lits'ebetsong tse ling tsa tlhahiso.
2. Ho hlahisa mohlala: Ho etsoa ka ho hatisa skrineng kapa ho nka linepe.
3. Etching process: Mahlakore ka bobeli a laminate ka mokhoa oa potoloho a qoelisoa ka tanka ea etching kapa a fafatsoa ka tharollo ea etching agent bakeng sa etching.
4. Mokhoa oa ho cheka ka mechine: Lisebelisoa tsa ho cheka ka mokhoa o nepahetseng kapa ho cheka ka botekgeniki li sebelisetsoa ho cheka likoti tse hlokahalang tsa potoloho, li-pads, le mekhoa ea ho phunya ka har'a liphanele tsa tlhahiso. Ka mohlala, theknoloji ea ho phunya laser.
5. Ts'ebetso ea koporo ea koporo: Sepheo sa ts'ebetso ea koporo ke ho kenya koporo e hlokahalang ka har'a likoti tse pentiloeng ho theha likhokahano tsa motlakase lipakeng tsa likarolo tsa boto e thata-thata.
6. Sebelisa lera la sekoahelo: Thepa ea sekoaelo (hangata filimi ea polyimide) le sekhomaretsi li hatisoa ka holim'a boto e thata-flex ka khatiso ea skrine.
7. Cover layer lamination: Lamination e etsoa ka mocheso o itseng, likhatello, le meeli ea vacuum ho etsa bonnete ba ho khomarela hantle ha lera la sekoahelo.
8. Etsa kopo ea likhopo tse matlafatsang: Likhopo tse eketsehileng tsa ho matlafatsa li ka sebelisoa pele ho ts'ebetso e eketsehileng ea lamination, ho itšetlehile ka litlhoko tsa moralo oa boto e thata-flex.
9. Flexible board cutting: Sebelisa mekhoa ea ho phunya ka hydraulic kapa lithipa tse khethehileng tsa ho phunya ho khaola boto e tenyetsehang ho tloha phanele ea tlhahiso.
10. Teko le netefatso ea motlakase: Liboto tse Rigid-flex li lekoa ka motlakase ho latela litataiso tsa IPC-ET-652 ho netefatsa ts'ebetso ea insulation, khokahano, boleng le ts'ebetso ea boto ea potoloho e fihlela litlhoko tsa litlhaloso tsa moralo. Mekhoa ea ho etsa liteko e kenyelletsa tlhahlobo ea probe e fofang le sistimi ea tlhahlobo ea grid.

Ts'ebetso ea tlhahiso e sa fetoheng ke khetho e nepahetseng bakeng sa ho aha lipotoloho indastering ea bongaka, ea sefofane, ea sesole le ea likhokahano hobane liboto tsena tsa potoloho li na le ts'ebetso e ntle haholo le mesebetsi e nepahetseng, haholo maemong a thata.

Hangata baenjiniere ba tiisa taba ena hammoho le tlhahiso ea potoloho e tenyetsehang le lintlha tsa PCB tsa transformer ea matla ha ba lokisa moaho o tšepahalang oa PCB kapa PCBA.
