FPC board hloov tauyog ib daim ntawv ntawm Circuit Court fabricated ntawm ib tug saj zawg zog finish nto, nrog los yog tsis muaj ib tug npog txheej (feem ntau yog siv los tiv thaiv FPC circuits). Vim tias FPC lub rooj tsavxwm tuaj yeem khoov, quav lossis rov txav mus rau ntau txoj hauv kev, piv nrog lub rooj tsavxwm zoo tib yam (PCB), muaj qhov zoo ntawm lub teeb, nyias, hloov tau, yog li nws daim ntawv thov ntau dua thiab dav, yog li peb yuav tsum tau. xyuam xim rau qhov peb tsim, cov hauv qab no me me ua kom hais meej.
Hauv kev tsim, FPC feem ntau yuav tsum tau siv nrog PCB, nyob rau hauv kev sib txuas ntawm ob feem ntau txais yuav lub rooj tsavxwm-rau-board connector, connector thiab kub ntiv tes, HOTBAR, mos thiab nyuaj ua ke board, phau ntawv vuam hom kev sib txuas, raws li sib txawv daim ntawv thov ib puag ncig, tus tsim qauv tuaj yeem txais cov kev sib txuas sib txuas.
Hauv kev siv cov tswv yim, nws tau txiav txim siab seb puas yuav tsum muaj kev tiv thaiv ESD raws li daim ntawv thov. Thaum FPC hloov pauv tsis siab, cov tawv tawv tawv thiab tuab tuab tuaj yeem siv los ua kom tiav. Thaum qhov kev xav tau ntawm kev hloov pauv siab, tooj liab mesh thiab cov nyiaj siv hluav taws xob tuaj yeem siv tau
Vim lub softness ntawm FPC mos phaj, nws yog ib qho yooj yim rau tawg nyob rau hauv kev ntxhov siab, yog li ib co tshwj xeeb txhais tau tias yuav tsum tau rau kev tiv thaiv FPC.
Cov txheej txheem feem ntau yog:
1. Qhov tsawg kawg nkaus lub vojvoog ntawm lub puab lub kaum sab xis ntawm lub flexible contour yog 1.6 hli. Qhov loj ntawm lub vojvoog, qhov siab dua qhov kev ntseeg tau thiab muaj zog dua lub kua muag. Ib txoj kab tuaj yeem raug ntxiv ze ntawm ntug ntawm lub phaj ntawm lub ces kaum ntawm cov duab los tiv thaiv FPC los ntawm kev tawg.
2. Cov kab nrib pleb lossis grooves hauv FPC yuav tsum xaus rau hauv lub voj voog tsis pub tsawg dua 1.5 hli hauv txoj kab uas hla, txawm tias ob lub FPCS uas nyob ib sab yuav tsum tau txav mus rau nyias.
3. Yuav kom ua tiav qhov kev hloov pauv tau zoo dua, qhov chaw khoov yuav tsum tau xaiv nyob rau hauv cheeb tsam uas muaj qhov dav dav, thiab sim kom tsis txhob FPC qhov sib txawv ntawm qhov dav thiab qhov tsis sib xws ntawm txoj kab hauv qhov chaw khoov.
STIffener board yog siv rau kev txhawb nqa sab nraud. Cov ntaub ntawv STIffener board suav nrog PI, Polyester, iav fiber ntau, polymer, aluminium ntawv, steel ntawv, thiab lwm yam. Tsim nyog tsim ntawm txoj hauj lwm, cheeb tsam thiab cov khoom siv ntawm cov phaj reinforcement plays lub luag haujlwm zoo hauv kev zam FPC tearing.
5. Nyob rau hauv ntau txheej FPC tsim, huab cua sib txawv stratification tsim yuav tsum tau nqa tawm rau cov cheeb tsam uas yuav tsum tau nquag khoov thaum lub sij hawm siv cov khoom. Nyias PI cov ntaub ntawv yuav tsum tau siv kom deb li deb tau los ua kom cov softness ntawm FPC thiab tiv thaiv FPC los ntawm kev tawg nyob rau hauv tus txheej txheem ntawm rov khoov.
6. Yog hais tias qhov chaw tso cai, ob-sided adhesive kho cheeb tsam yuav tsum tau tsim nyob rau hauv kev sib txuas ntawm cov ntiv tes kub thiab connector los tiv thaiv kub ntiv tes thiab connector los ntawm ntog thaum lub sij hawm khoov.
7. FPC positioning silk screen kab yuav tsum tau tsim los ntawm kev sib txuas ntawm FPC thiab connector los tiv thaiv kev sib txawv thiab tsis tsim nyog ntawm FPC thaum sib dhos. Yooj yim rau kev tshuaj xyuas ntau lawm.
Vim yog qhov tshwj xeeb ntawm FPC, xyuam xim rau cov ntsiab lus hauv qab no thaum lub sij hawm cable:
Routing txoj cai: Muab qhov tseem ceeb kom ntseeg tau tias lub teeb liab routing, ua raws li lub hauv paus ntsiab lus ntawm luv luv, ncaj thiab ob peb lub qhov, tsis txhob ntev, nyias thiab ncig routing kom deb li deb tau, coj kab rov tav, ntsug thiab 45 degree kab ua lub ntsiab, tsis txhob arbitrary Angle kab. , khoov ib feem ntawm kab radian, cov ntsiab lus saum toj no yog raws li hauv qab no:
1. Kab dav: Xav txog tias txoj kab dav dav ntawm cov ntaub ntawv cable thiab lub hwj chim cable tsis sib haum, qhov chaw nruab nrab tshwj xeeb rau kev xaim yog 0.15mm
2. Kab sib nrug: Raws li lub peev xwm ntau lawm ntawm cov tuam ntxhab feem ntau, cov qauv tsim kab sib nrug (Pitch) yog 0.10mm
3. Kab npoo: qhov kev ncua deb ntawm cov kab sab nraud thiab FPC contour yog tsim los ua 0.30mm. Qhov loj dua qhov chaw tso cai, qhov zoo dua
4. Sab hauv fillet: Qhov tsawg kawg nkaus sab hauv fillet ntawm FPC contour yog tsim raws li lub vojvoog R = 1.5mm
5. Tus neeg xyuas pib yog perpendicular rau txoj kev khoov
6. Cov hlau yuav tsum sib npaug ntawm qhov chaw khoov
7. Tus neeg xyuas pib yuav tsum npog qhov chaw khoov kom ntau li ntau tau
8. Tsis muaj plating hlau ntxiv rau hauv qhov chaw khoov (cov xov hlau hauv qhov chaw khoov tsis yog plating)
9. Khaws cov kab dav kom zoo ib yam
10. Kev sib txuas ntawm ob lub vaj huam sib luag tsis tuaj yeem sib tshooj los ua ib qho "Kuv" zoo li
11. Txo tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm qhov nkhaus
12. Yuav tsum tsis txhob muaj qhov los ntawm qhov thiab metallized qhov hauv qhov chaw khoov
13. Lub bending center axis yuav tsum tau teem rau ntawm qhov chaw ntawm cov hlau. Cov khoom coefficient thiab thickness ntawm ob sab ntawm tus neeg xyuas pib yuav tsum zoo ib yam li qhov ua tau. Qhov no tseem ceeb heev nyob rau hauv dynamic dabtsi yog khoov daim ntawv thov.
14. Kab rov tav torsion ua raws li cov hauv paus ntsiab lus hauv qab no ---- txo qhov khoov seem kom yooj yim dua, los yog ib nrab ua rau thaj tsam tooj liab kom muaj zog ntxiv.
15. Lub vojvoog dabtsi yog khoov ntawm lub dav hlau ntsug yuav tsum tau nce ntxiv thiab cov txheej txheem ntawm qhov chaw khoov yuav tsum raug txo kom tsawg.
16. Rau cov khoom uas yuav tsum tau EMI, yog hais tias muaj ntau zaus hluav taws xob teeb liab kab xws li USB thiab MIPI nyob rau FPC, conductive silver foil txheej yuav tsum tau ntxiv thiab grounded rau FPC raws li EMI ntsuas los tiv thaiv EMI.
