Qhov kev xaiv ntawm ib qho nyuaj -flex PCB thiab cov qauv hloov pauv tau zoo li cov lus nug tshwj xeeb, tab sis qhov no yog qhov kev txiav txim siab ntawm cov khoom lag luam uas cuam tshuam rau hauv cov nqi tsim khoom, kev sib dhos nyuaj, thiab kev ua haujlwm ntev -. Peb tau pom cov pab pawg engineering siv sijhawm ntau lub limtiam txhim kho tus qauv tsim tsuas yog kom paub txog ib nrab ntawm -txoj kev los ntawm NPI tias qhov nruj -flex hybrid yuav ua kom yooj yim rau lawv cov teeb meem txuas tag nrho. Ntawm CSNT-EMS hauv Dongguan, peb niaj hnub pab pawg ua haujlwm los ntawm kev ua lag luam no- tawm ua ntej lawv cog lus rau ib qho kev qhia tshwj xeeb.
Nkag siab txog Qhov Tseem Ceeb Qhov txawv
Tus qauv hloov pauv hloov pauv (FPC) siv polyimide (PI) zaj duab xis dielectric uas tuaj yeem ua raws li pob khoom thaum lub sijhawm teeb tsa lossis thaum kawg - siv kev pabcuam. Ib qho nruj-flex PCB sib txuas cov ntu khoov nrog cov ntu nruj (feem ntau FR4) hauv ib qho kev sib xyaw ua ke. Cov ntu nruj muab qhov chaw mounting rau cov khoom thiab cov khoom sib txuas. Cov ntu dabtsi yog khoov muab qhov dynamic lossis zoo li qub flexing muaj peev xwm.
Qhov sib txawv ntawm cov txheej txheem tsav cov txheej txheem tsim khoom sib txawv. Ib qho ntshiab -bending tsim yog tsim los ntawm cov khoom siv polyimide thiab tooj liab. Ib qho nruj-flex yuav tsum tau ua raws li lamination qhov twg cov txheej txheem polyimide tau sib koom ua ke rau cov txheej txheem nruj hauv qab tswj qhov kub thiab txias. Qhov no ua rau nruj -flex ntau kim ib square centimeter dua ib tug ntshiab - khoov tsim.
Thaum Lub Rooj Tswjhwm Saib Xyuas Ib Leeg Ib Leeg yog qhov kev xaiv zoo
Ntshiab- dabtsi yog khoov FPC tsim ua rau muaj kev nkag siab zoo thaum tag nrho lub rooj tsavxwm yuav tsum ua raws li lub pob zoo, thaum daim ntawv zoo xav kom lub rooj tsavxwm muab ntim rau hauv ib lub pob compact, lossis thaum lub rooj tsavxwm yuav muaj kev rov ua haujlwm zoo dua qub hauv kev pabcuam.
Ib qho -sided designs yog qhov qis tshaj - kev xaiv tus nqi rau cov ntawv thov yooj yim xws li LED strip connectors lossis ib daim ntawv thov -axis. Ob chav -sided designs txhawb nqa txoj kev nyuaj dua tab sis yuav tsum tau plated los ntawm - qhov, uas ntxiv cov txheej txheem nqi.
Qhov kev txwv tseem ceeb ntawm cov ntshiab - khoov FPC tsim yog cov khoom sib txuas. Koj tsis tuaj yeem nto mount cov khoom ntawm cov ntshiab polyimide vim tias cov khoom siv tsis muaj kev txhawb nqa txhua yam rau reflow soldering los yog rau cov khoom uas muaj kev ntxhov siab thaum ua haujlwm. Cheebtsam yuav tsum tau mounted rau nruj seem los yog ntawm stiffeners bonded rau lub polyimide cheeb tsam.
Thaum Rigid-Flex ua rau muaj kev xav ntau dua
Rigid-flex PCBs ua tau zoo hauv peb qhov xwm txheej tshwj xeeb.
Ua ntej, thaum koj cov khoom yuav tsum tau nto mount Cheebtsam ntawm ib tug nruj -flex PCB nyob rau hauv cov cheeb tsam uas tsis flex. Cov ntu FR4 nruj muab kev txhawb nqa txhua yam xav tau rau kev txhim khu kev qha reflow soldering thiab cov khoom txuas.
Qhov thib ob, thaum koj tus tsim FPC xav tau kom txo cov connector suav. Tsis yog siv cov khoom sib txuas sib txuas los txuas lub rooj tsav xwm nruj mus rau ntu dabtsi yog khoov, nruj -flex PCB integrates kev sib txuas sab hauv, uas txo cov impedance discontinuities thiab txuag board chaw.
Thib peb, thaum koj qhov nruj -flex FPC yuav rov ua dua dynamic dabtsi yog khoov thiab xav tau kev cuam tshuam nrog cov ntu ntu ntu. Piv txwv muaj xws li cov lus qhia foldable, lidar modules nrog cov lus piav qhia, thiab aerospace payloads nrog rau kev xa tawm mechanisms.
Ib lub chaw tsim khoom siv kho mob uas peb tau ua haujlwm nrog tau xub teev tseg ib qho nyuaj PCB txuas nrog ntawm 0.5mm tus pin header. Hloov mus rau ob -txheej txheej nruj- flex tsim tshem tawm cov khoom sib txuas, txo qhov kev sib dhos hneev taw los ntawm 18 feem pua, thiab txhim kho cov teeb liab kev ncaj ncees ntawm qhov sib txuas.
Rigid-flex vs cais nruj + FPC sib dhos sib piv
Khoom siv thiab txheej txheem nqi sib txawv
Cov nqi ntawm cov khoom siv rau cov ntshiab-bending designs khiav siab tshaj FR4 nruj vim polyimide zaj duab xis thiab saj zawg zog tooj liab clad laminate (FCCL) yog siab dua - cov ntaub ntawv nqi. Panasonic R-F777 PI FCCL thiab Taiflex FHK0515 coverlay yog ib qho kev qhia tshwj xeeb uas cuam tshuam txog tus nqi no.
Rigid-flex ntxiv tus nqi ntawm cov txheej txheem lamination, uas yuav tsum tau ua ntau cov kauj ruam thiab lub sij hawm voj voog ntev dua li txheej txheem nruj PCB fabrication. Tus naj npawb ntawm cov txheej txheem polyimide, tus naj npawb ntawm cov txheej txheem nruj, thiab qhov nyuaj ntawm txoj kev hloov chaw txhua tus nqi tsav tsheb.
Rau kev sib piv tus nqi ntxhib, plaub- txheej nruj- flex PCB feem ntau raug nqi 40 mus rau 80 feem pua ntau tshaj plaub qhov sib npaug -txheej PCB nrog ob qhov sib cais - txheej sib txuas. Tus nqi them tiag tiag yog nyob ntawm cov txheej txheem suav, pawg thawj coj saib, thiab geometry.
Kev txiav txim siab rau koj daim ntawv thov
Rau nruj -flex FPC tsim, pib nrog qhov kev tso kawm ntawm qhov txwv. Yog tias tag nrho cov khoom tuaj yeem zaum ntawm cov ntu nruj thiab qhov yuav tsum tau khoov tsuas yog txwv rau ob peb qhov chaw uas tau hais tseg, qhov ntshiab - khoov tsim nrog ib qho kev sib txuas tsis sib xws yuav yog tus nqi qis tshaj - txoj kev. Yog tias cov khoom yuav tsum tau muab tso rau hauv ntau lub dav hlau lossis yog qhov kev sib tw ntawm cov ntu ntu yuav tsum muaj siab -kev sib tshuam, nruj-flex feem ntau yeej ntawm tag nrho cov nqi txawm tias lub rooj tsavxwm nws tus kheej raug nqi ntau dua.
Stackup complexity yog lwm yam. Rigid-flex yuav tsum tau ceev faj tswj cov kab mob siab dhau los ntawm lamination. Ua hauj lwm nrog tus neeg tsim khoom thaum ntxov hauv theem tsim pab txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv dhau los ua cov blockers ntau lawm.
