Nyob rau hauv xyoo tas los no, rigid-flex PCBs tau dhau los ua neeg nyiam vim lawv qhov sib xyaw ua ke ntawm kev yooj yim thiab ua haujlwm ntev. Hom kab hluav taws xob no tso cai rau cov neeg tsim qauv tsim cov kev daws teeb meem tshiab thiab txuag chaw, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas cov rooj sib tsoo tsoos tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua. Thaum rigid-flex PCBs muaj ntau yam kev tsim tsim, tseem muaj qee qhov kev txwv uas yuav tsum tau xav txog, tshwj xeeb yog hais txog khoov radii.
Lub vojvoog khoov ntawm PCB yog lub vojvoog me tshaj plaws uas lub rooj tsavxwm tuaj yeem khoov tau zoo yam tsis muaj kev puas tsuaj rau cov kab lossis cov khoom.Rau rigid-flex boards, dabtsi yog khoov vojvoog yog ib qho tseem ceeb parameter uas ncaj qha cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev cia siab ntawm lub Circuit Court board.
Thaum tsim ib lub rigid-flex PCB, koj yuav tsum nkag siab txog cov kev txwv los ntawm lub vojvoog khoov.Tshaj qhov khoov lub vojvoog tau pom zoo yuav ua rau muaj teeb meem xws li kab delamination, tawg, lossis txawm tias cov khoom tsis ua haujlwm. Yog li ntawd, qhov nam no yuav tsum tau ua tib zoo txiav txim siab thaum lub sij hawm tsim qauv los xyuas kom meej kev ua haujlwm zoo thiab lub neej ntev ntawm lub rooj tsavxwm.
Qhov khoov vojvoog txwv rau nruj-flex PCBs nyob ntawm ntau yam, suav nrog cov khoom siv, cov txheej txheem, thiab tag nrho cov board thickness.Cia peb delve tob rau hauv txhua yam kom nkag siab zoo dua lawv qhov cuam tshuam:
1. Cov khoom siv ntawm kev tsim kho:Kev xaiv ntawm cov ntaub ntawv, xws li cov khoom siv hauv paus thiab cov ntaub ntawv hloov tau yooj yim siv, ncaj qha cuam tshuam rau qhov khoov vojvoog txwv. Cov ntaub ntawv sib txawv muaj cov yam ntxwv sib txawv, uas cuam tshuam rau qhov qis qis qis. Piv txwv li, polyimide yog ib qho kev xaiv rau qhov hloov tau yooj yim vim nws yooj yim heev thiab kub tsis kam. Txawm li cas los xij, kev xaiv cov khoom siv yuav tsum tau ua tib zoo sib npaug, vim tias siv cov khoom siv uas hloov tau yooj yim tuaj yeem ua rau kev khoov ntau dhau thiab ua rau lub rooj tsav xwm puas tsuaj.
2. Cov txheej txheem:Tus naj npawb ntawm cov khaubncaws sab nraud povtseg ntawm rigid-flex board yuav cuam tshuam rau lub vojvoog dabtsi yog khoov. Feem ntau hais lus, ntau txheej ntawm lub rooj tsavxwm muaj, qhov loj dua qhov khoov vojvoog yuav tsum yog. Qhov no yog vim hais tias cov txheej txheem ntxiv qhia txog kev nruj dua, ua rau lub rooj tsavxwm nyuaj rau khoov yam tsis muaj straining cov kab lossis ua rau lwm yam teeb meem. Cov neeg tsim qauv yuav tsum ua tib zoo xav txog cov txheej txheem uas yuav tsum tau ua rau ib daim ntawv thov tshwj xeeb thiab kho lub vojvoog khoov kom haum.
3. Zuag qhia tag nrho thickness ntawm lub phaj:Lub thickness ntawm lub phaj kuj plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab khoov vojvoog txwv. Cov phaj tuab zoo li yuav muaj qhov tsawg kawg nkaus khoov radii dua li daim hlau nyias. Raws li board thickness nce, cov khoom yuav khov, yuav tsum tau ib tug loj dabtsi yog khoov vojvoog kom tsis txhob muaj tej yam kev puas tsuaj.
Thaum txiav txim siab txog cov xwm txheej no thiab txiav txim siab qhov txwv flex rau rigid-flex PCBs, nws tseem ceeb heev uas yuav tsum xav txog lwm yam uas yuav cuam tshuam rau pawg thawj coj saib kev ua haujlwm.Piv txwv li, cov kev thov tshwj xeeb xws li qhov yuav tsum tau ua kom yooj yim los yog cuam tshuam ntawm lub rooj tsav xwm hauv Circuit Court rau qhov kub thiab txias tuaj yeem cuam tshuam ntxiv rau cov kev txwv lub vojvoog.
Txhawm rau kom ntseeg tau tias qhov zoo tshaj plaws khoov radii rau rigid-flex boards, nws raug nquahu kom ua haujlwm ze nrog cov tuam txhab paub txog thiab cov neeg tsim qauv uas muaj kev paub ntau thiab kev txawj ntse hauv daim teb no.Lawv tuaj yeem muab kev pom zoo, kev taw qhia thiab kev txhawb nqa thoob plaws hauv kev tsim thiab tsim khoom. Tsis tas li ntawd, kev siv cov cuab yeej simulation siab heev thiab ua qhov kev sim ua kom zoo tuaj yeem pab txheeb xyuas qhov kev xaiv khoov lub vojvoog thiab ua kom lub rooj tsavxwm muaj kev ntseeg siab thiab ua haujlwm ntev.
Hauv cov ntsiab lus, txawm hais tias nruj-flex PCBs muaj ntau yam kev tsim muaj peev xwm, lawv cov kev txwv qhov nkhaus yuav tsum tau txiav txim siab.Qhov kev xaiv ntawm cov khoom siv, tus naj npawb ntawm cov khaubncaws sab nraud povtseg thiab tag nrho cov vaj huam sib luag thickness ncaj qha cuam tshuam rau qhov khoov vojvoog txwv. Los ntawm ua tib zoo ntsuas cov ntsiab lus no thiab txiav txim siab txog kev thov tshwj xeeb, cov neeg tsim qauv tuaj yeem tsim kom muaj zog thiab txhim khu kev qha rigid-flex PCBs uas ua tau raws li qhov yuav tsum tau ua kom yooj yim thaum tsis txhob muaj teeb meem cuam tshuam txog kev khoov. Ua haujlwm nrog cov kws tshaj lij thiab siv cov cuab yeej simulation siab heev tuaj yeem pab txhawb kev ua tiav ntawm cov qauv PCB nruj-flex.
