Khoom taw qhia

Flexible circuit board (FPC), tseem hu ua flexible circuit board, flexible circuit board, nws lub teeb yuag, nyias thickness, dawb dabtsi yog khoov thiab folding thiab lwm yam ntxwv zoo heev.Txawm li cas los xij, kev tshuaj xyuas zoo hauv tsev ntawm FPC feem ntau yog nyob ntawm kev tshuaj xyuas qhov muag pom, uas yog tus nqi siab thiab ua haujlwm qis.Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob, kev tsim hluav taws xob hauv Circuit Court tau dhau los ua ntau qhov kev txiav txim siab thiab siab ceev, thiab cov txheej txheem kev tshawb nrhiav ib txwm tsis tuaj yeem ua tau raws li cov kev xav tau ntau lawm, thiab tsis siv neeg tshawb pom ntawm FPC tsis xws luag tau dhau los ua ib qho tseem ceeb. trend of industrial development.

Flexible Circuit Court (FPC) yog ib lub tshuab tsim los ntawm Tebchaws Meskas rau kev tsim cov tshuab foob pob hluav taws hauv lub xyoo 1970s.Nws yog cov ntawv luam tawm uas muaj kev ntseeg siab thiab zoo heev ua los ntawm polyester zaj duab xis los yog polyimide ua substrate.Los ntawm embedding lub Circuit Court tsim ntawm ib tug saj zawg zog nyias yas ntawv, ib tug loj tus naj npawb ntawm precision Cheebtsam yog embedded nyob rau hauv ib tug nqaim thiab txwv qhov chaw.Yog li tsim ib lub voj voog hloov tau yooj yim.Qhov Circuit Court no tuaj yeem khoov thiab folded ntawm lub siab, lub teeb yuag, me me, zoo cua sov dissipation, yooj yim installation, tawg los ntawm cov tsoos interconnection technology.Nyob rau hauv cov qauv ntawm ib tug saj zawg zog Circuit Court, cov ntaub ntawv uas muaj xws li ib tug insulating zaj duab xis, ib tug neeg xyuas pib thiab ib tug neeg sawv cev sib txuas.

Cov khoom siv 1, rwb thaiv tsev zaj duab xis

Cov zaj duab xis insulating tsim cov txheej txheej hauv Circuit Court, thiab cov nplaum nplaum ua cov ntawv ci tooj liab rau cov txheej insulating.Nyob rau hauv ib tug multi-txheej tsim, nws yog ces khi rau lub puab txheej.Lawv kuj tseem siv los tiv thaiv kev tiv thaiv kev tiv thaiv hluav taws xob los ntawm cov plua plav thiab noo noo, thiab txhawm rau txo kev ntxhov siab thaum lub sij hawm flexure, tooj liab ntawv ci tsim ib txheej conductive.

Hauv qee qhov kev hloov pauv tau yooj yim, cov khoom siv nruj tsim los ntawm txhuas lossis stainless hlau yog siv, uas tuaj yeem muab kev ruaj ntseg, muab kev txhawb nqa lub cev rau kev tso kawm ntawm cov khoom thiab cov xov hlau, thiab tso tawm kev ntxhov siab.Adhesive khi cov khoom nruj rau lub voj voog hloov tau.Tsis tas li ntawd, lwm cov khoom siv qee zaum siv rau hauv kev hloov pauv hloov pauv, uas yog txheej nplaum, uas yog tsim los ntawm txheej txheej ntawm ob sab ntawm cov yeeb yaj kiab insulating nrog cov nplaum.Adhesive laminates muab kev tiv thaiv ib puag ncig thiab hluav taws xob rwb thaiv tsev, thiab muaj peev xwm tshem tawm ib zaj duab xis nyias, nrog rau kev muaj peev xwm sib txuas ntau txheej nrog tsawg txheej.

Muaj ntau hom ntaub ntawv insulating zaj duab xis, tab sis feem ntau siv yog polyimide thiab polyester cov ntaub ntawv.Ze li 80% ntawm tag nrho cov chaw tsim hluav taws xob hloov pauv hauv Tebchaws Meskas siv cov ntaub ntawv polyimide, thiab li 20% siv cov ntaub ntawv polyester.Polyimide cov ntaub ntawv muaj cov nplaim taws, ruaj khov geometrical dimension thiab muaj lub zog tsim kua muag, thiab muaj peev xwm tiv taus qhov kub thiab txias, polyester, tseem hu ua polyethylene ob phthalates (Polyethyleneterephthalate hu ua: PET), nws lub cev muaj zog zoo ib yam li polyimides, Nws muaj qhov qis dielectric tas li, absorbs me ntsis noo noo, tab sis tsis tiv taus qhov kub thiab txias.Polyester muaj qhov melting point ntawm 250 ° C thiab lub iav hloov pauv kub (Tg) ntawm 80 ° C, uas txwv tsis pub lawv siv hauv cov ntawv thov uas yuav tsum muaj qhov kawg vuam.Hauv cov ntawv thov kub qis, lawv qhia rigidity.Txawm li cas los xij, lawv tsim nyog siv rau hauv cov khoom xws li xov tooj thiab lwm yam uas tsis tas yuav raug rau qhov chaw hnyav.Polyimide insulating zaj duab xis feem ntau yog ua ke nrog polyimide lossis acrylic nplaum, polyester insulating cov ntaub ntawv feem ntau ua ke nrog polyester nplaum.Qhov kom zoo dua ntawm kev sib txuas nrog cov khoom siv nrog cov yam ntxwv zoo ib yam tuaj yeem muaj qhov ruaj khov tom qab vuam qhuav lossis tom qab ntau lub voj voog lamination.Lwm yam khoom tseem ceeb hauv cov nplaum yog qhov tsis tshua muaj hluav taws xob tsis tu ncua, kev rwb thaiv tsev siab, siab hloov iav kub thiab tsis tshua muaj dej nqus.

2. Tus coj

Copper foil yog tsim rau siv nyob rau hauv kev hloov pauv hloov pauv, nws tuaj yeem ua Electrodeposited (ED), lossis plated.Cov ntawv ci tooj liab nrog hluav taws xob tso tawm muaj qhov ci ntsa iab ntawm ib sab, thaum lub ntsej muag ntawm lwm sab yog npub thiab npub.Nws yog cov khoom siv hloov tau yooj yim uas tuaj yeem ua rau ntau qhov tuab thiab dav, thiab sab dull ntawm ED tooj liab ntawv ci feem ntau tshwj xeeb kho los txhim kho nws lub peev xwm sib txuas.Ntxiv nrog rau nws yooj yim, forged tooj liab ntawv ci kuj muaj cov yam ntxwv ntawm cov tawv thiab du, uas yog tsim rau cov ntawv thov uas yuav tsum tau dynamic dabtsi yog khoov.

3. Adhesive

Ntxiv nrog rau kev siv los txuas cov yeeb yaj kiab insulating rau cov khoom siv hluav taws xob, cov nplaum kuj tuaj yeem siv los ua cov txheej txheej, ua cov txheej tiv thaiv, thiab ua cov txheej txheej.Qhov sib txawv tseem ceeb ntawm ob qhov lus dag nyob rau hauv daim ntawv thov siv, qhov twg cov cladding bonded rau lub npog rwb thaiv tsev zaj duab xis yog tsim ib tug laminated tsim Circuit Court.Screen printing tshuab siv rau txheej cov nplaum.Tsis yog txhua lub laminates muaj cov nplaum, thiab cov laminates tsis muaj cov nplaum ua rau nyias nyias thiab yooj yim dua.Piv nrog rau cov qauv laminated raws li cov nplaum, nws muaj thermal conductivity zoo dua.Vim tias cov qauv nyias nyias ntawm cov tsis-nplaum hloov tau yooj yim, thiab vim tias tshem tawm cov thermal tsis kam ntawm cov nplaum, yog li txhim kho cov thermal conductivity, nws tuaj yeem siv rau hauv qhov chaw ua haujlwm qhov chaw hloov pauv raws li cov nplaum laminated qauv. siv tsis tau.

Kev kho mob ua ntej yug menyuam

Hauv cov txheej txheem tsim khoom, txhawm rau tiv thaiv kev qhib luv luv luv thiab ua rau cov khoom qis dhau los lossis txo qhov drilling, calender, txiav thiab lwm yam teeb meem txheej txheem los ntawm FPC board seem, teeb meem ntxiv, thiab ntsuas seb yuav xaiv cov ntaub ntawv li cas kom ua tiav qhov zoo tshaj plaws. Cov txiaj ntsig ntawm cov neeg siv khoom ntawm cov khoom siv hluav taws xob hloov tau yooj yim, kev kho ua ntej yog qhov tseem ceeb tshwj xeeb.

Kev kho mob ua ntej, muaj peb yam uas yuav tsum tau ua nrog, thiab peb yam no tau ua tiav los ntawm engineers.Thawj yog FPC pawg thawj coj saib xyuas engineering, feem ntau yog los ntsuas seb tus neeg siv khoom FPC lub rooj tsavxwm puas tuaj yeem tsim tau, seb lub tuam txhab lub peev xwm ntau lawm tuaj yeem ua tau raws li cov neeg siv khoom lub rooj tsavxwm thiab cov nqi tsev;Yog tias qhov kev ntsuam xyuas tiav lawm, cov kauj ruam tom ntej yog npaj cov ntaub ntawv tam sim ntawd kom tau raws li cov khoom siv raw rau txhua qhov txuas.Thaum kawg, tus engineer yuav tsum: Tus neeg siv khoom CAD qauv kos duab, gerber kab cov ntaub ntawv thiab lwm yam ntaub ntawv engineering tau ua tiav kom haum rau qhov chaw tsim khoom thiab cov khoom siv ntau lawm, thiab tom qab ntawd cov duab kos duab thiab MI (engineering process card) thiab lwm yam ntaub ntawv yog xa mus rau lub tuam tsev tsim khoom, tswj cov ntaub ntawv, kev yuav khoom thiab lwm lub tuam tsev kom nkag mus rau cov txheej txheem ntau lawm.
