Vim nws cov qauv complex thiab cov yam ntxwv tshwj xeeb,kev tsim cov rigid-flex boards yuav tsum muaj kev tsim tshwj xeeb. Hauv tsab ntawv tshaj tawm no, peb yuav tshawb txog ntau yam kev koom tes hauv kev tsim cov txheej txheem nruj heev ntawm PCB boards thiab qhia txog cov kev xav tshwj xeeb uas yuav tsum tau muab coj los xav.
Printed circuit boards (PCBs) yog lub hauv paus ntawm cov khoom siv hluav taws xob niaj hnub no. Lawv yog lub hauv paus rau cov khoom siv hluav taws xob sib txuas, ua rau lawv yog ib feem tseem ceeb ntawm ntau yam khoom siv uas peb siv txhua hnub. Raws li thev naus laus zis nce qib, yog li xav tau kev hloov pauv tau yooj yim dua thiab kev daws teeb meem. Qhov no tau ua rau muaj kev txhim kho ntawm rigid-flex PCBs, uas muaj kev sib xyaw tshwj xeeb ntawm kev nruj thiab yoog raws ntawm ib lub rooj tsavxwm.
Tsim rigid-flexible board
Thawj thiab tseem ceeb tshaj plaws hauv cov txheej txheem kev tsim khoom nruj-flex yog tsim. Tsim ib lub rooj tsavxwm nruj-flex yuav tsum tau ua tib zoo xav txog tag nrho lub rooj tsav xwm Circuit Court layout thiab qhov chaw tso khoom. Flex cheeb tsam, khoov radii thiab fold cheeb tsam yuav tsum tau txhais thaum lub sij hawm tsim theem kom paub meej tias zoo functionality ntawm lub tiav lawm board.
Cov ntaub ntawv siv rau hauv cov PCB nruj-flex yuav tsum tau ua tib zoo xaiv kom ua tau raws li cov cai tshwj xeeb ntawm daim ntawv thov. Kev sib xyaw ua ke ntawm cov khoom nruj thiab hloov tau yooj yim yuav tsum tau xaiv cov ntaub ntawv uas muaj kev sib xyaw ua ke ntawm kev yooj yim thiab rigidity. Feem ntau hloov tau yooj yim substrates xws li polyimide thiab nyias FR4 yog siv, nrog rau cov ntaub ntawv nruj xws li FR4 lossis hlau.
Txheej Stacking thiab Npaj cov Substrate rau nruj flex pcb manufacturing
Thaum tsim tiav, txheej txheej txheej txheej txheej pib. Rigid-flex printed circuit boards muaj ntau txheej txheej ntawm cov tawv tawv thiab hloov tau yooj yim uas tau sib koom ua ke siv cov nplaum tshwj xeeb. Qhov kev sib txuas no ua kom cov khaubncaws sab nraud povtseg txawm tias nyob rau hauv cov xwm txheej nyuaj xws li kev vibration, dabtsi yog khoov thiab kub hloov.
Cov kauj ruam tom ntej hauv kev tsim khoom yog npaj cov substrate. Qhov no suav nrog kev tu thiab kho qhov chaw kom ntseeg tau tias qhov zoo tshaj plaws adhesion. Cov txheej txheem ntxuav tshem tawm cov kab mob uas tuaj yeem cuam tshuam cov txheej txheem kev sib txuas, thaum kev kho saum npoo txhim kho qhov adhesion ntawm cov txheej txheem sib txawv. Cov txheej txheem xws li kev kho ntshav ntshav lossis tshuaj etching feem ntau yog siv los ua kom tiav cov khoom uas xav tau.
Copper patterning thiab puab txheej tsim rau rigid saj zawg zog Circuit Court boards facbrication
Tom qab npaj lub substrate, mus rau qhov txheej txheem tooj liab. Qhov no suav nrog tso cov txheej nyias ntawm tooj liab rau ntawm lub substrate thiab tom qab ntawd ua cov txheej txheem photolithography los tsim cov qauv Circuit Court uas xav tau. Tsis zoo li PCBs ib txwm muaj, rigid-flex PCBs yuav tsum tau ua tib zoo xav txog qhov hloov pauv tau thaum lub sijhawm ua qauv. Kev saib xyuas tshwj xeeb yuav tsum tau ua kom tsis txhob muaj kev ntxhov siab lossis kev puas tsuaj rau qhov hloov pauv ntawm lub rooj tsav xwm Circuit Court.
Thaum tooj liab qauv tiav, txheej txheej sab hauv pib. Hauv cov kauj ruam no, cov txheej txheem nruj thiab hloov tau yooj yim yog ua raws thiab kev sib txuas ntawm lawv tau tsim. Qhov no feem ntau ua tiav los ntawm kev siv vias, uas muab kev sib txuas hluav taws xob ntawm cov txheej txheem sib txawv. Vias yuav tsum tau ua tib zoo tsim kom haum raws li qhov yooj yim ntawm lub rooj tsavxwm, kom ntseeg tau tias lawv tsis cuam tshuam nrog kev ua haujlwm tag nrho.
Lamination thiab txheej txheej txheej rau nruj-flex pcb raug
Thaum txheej txheej sab hauv tsim, txheej txheem lamination pib. Qhov no suav nrog stacking tus neeg txheej thiab ua rau lawv kub thiab siab. Thaum tshav kub kub thiab siab ua kom cov nplaum nplaum thiab txhawb kev sib txuas ntawm cov khaubncaws sab nraud povtseg, tsim kom muaj cov qauv ruaj khov thiab ruaj khov.
Tom qab lamination, txheej txheej txheej txheej pib pib. Qhov no suav nrog tso ib txheej nyias ntawm tooj liab rau sab nrauv ntawm lub rooj tsav xwm hauv Circuit Court, ua raws li txheej txheem photolithography los tsim cov qauv Circuit Court kawg. Tsim cov txheej txheej sab nrauv yuav tsum tau ua kom raug thiab raug kom muaj kev sib raug zoo ntawm cov qauv hauv Circuit Court nrog cov txheej sab hauv.
Drilling, plating thiab deg kev kho mob rau rigid saj zawg zog pcb boards ntau lawm
Cov kauj ruam tom ntej hauv kev tsim khoom yog drilling. Qhov no suav nrog qhov drilling qhov hauv PCB kom tso cai rau cov khoom sib txuas thiab kev sib txuas hluav taws xob. Rigid-flex PCB drilling xav tau cov cuab yeej tshwj xeeb uas tuaj yeem ua kom haum cov thicknesses sib txawv thiab hloov tau yooj yim Circuit Court boards.
Tom qab drilling, electroplating yog ua los txhim kho cov conductivity ntawm PCB. Qhov no suav nrog tso cov txheej nyias ntawm cov hlau (feem ntau yog tooj liab) rau ntawm phab ntsa ntawm lub qhov drilled. Plated qhov muab ib txoj kev txhim khu kev qha ntawm kev tsim hluav taws xob sib txuas ntawm cov txheej txheem sib txawv.
Thaum kawg, nto tiav yog ua. Qhov no suav nrog kev siv cov txheej tiv thaiv rau cov khoom siv tooj liab los tiv thaiv corrosion, txhim khu kev ua haujlwm zoo, thiab txhim kho kev ua tau zoo ntawm lub rooj tsavxwm. Nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, muaj kev kho deg sib txawv, xws li HASL, ENIG lossis OSP.
Kev tswj kom zoo thiab kev sim rau nruj flex printed Circuit Court board manufacturing
Thoob plaws hauv tag nrho cov txheej txheem tsim khoom, kev tswj xyuas kev ua tau zoo yog siv los xyuas kom meej cov qauv siab tshaj plaws ntawm kev ntseeg siab thiab kev ua haujlwm. Siv cov kev sim siab tshaj plaws xws li kev tshuaj ntsuam xyuas qhov muag (AOI), X-ray kuaj thiab kuaj hluav taws xob txhawm rau txheeb xyuas qhov muaj peev xwm lossis teeb meem hauv lub rooj tsav xwm tiav. Tsis tas li ntawd, kev ntsuam xyuas ib puag ncig thiab kev ntseeg siab tau ua kom ntseeg tau tias cov PCBs nruj-flex tuaj yeem tiv taus cov xwm txheej nyuaj.
Los xaus
Kev tsim cov rigid-flex boards xav tau kev tsim khoom tshwj xeeb. Cov txheej txheem nyuaj thiab cov yam ntxwv tshwj xeeb ntawm cov kev tshaj lij Circuit Court boards yuav tsum tau ua tib zoo xav txog kev tsim qauv, kev xaiv cov khoom raug thiab cov txheej txheem tsim khoom. Los ntawm kev ua raws li cov txheej txheem tsim tshwj xeeb no, cov tuam txhab hluav taws xob tuaj yeem siv tag nrho cov peev txheej ntawm rigid-flex PCBs thiab coj cov hauv kev tshiab rau cov khoom siv hluav taws xob tshiab, hloov tau yooj yim thiab compact.
