Kev txiav txim siab tsim qauv rau ntau txheej hloov pauv PCBs ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau thiab ua haujlwm ntawm cov khoom siv hluav taws xob. Raws li kev siv thev naus laus zis txuas ntxiv mus, qhov kev thov rau PCB hloov pauv tau loj hlob sai vim lawv qhov txiaj ntsig ntau ntawm kev txo qhov loj me, txo qhov hnyav, thiab nce ntau yam. Txawm li cas los xij, tsim kom muaj ntau yam hloov pauv PCB yuav tsum tau ua tib zoo xav txog ntau yam los xyuas kom meej qhov ua tau zoo.Hauv tsab ntawv tshaj tawm no, peb tshawb nrhiav cov ntsiab lus tseem ceeb ntawm kev tsim qauv rau ntau cov txheej txheem hloov pauv PCBs thiab sib tham txog cov teeb meem cuam tshuam nrog lawv cov txheej txheem tsim thiab tsim khoom.
Ib qho ntawm cov qauv tsim tseem ceeb rau ntau txheej flex PCBs yog kev xaiv cov khoom siv substrate.Flexible PCBs cia siab rau cov ntaub ntawv hloov pauv tau yooj yim xws li polyimide (PI) lossis polyester (PET) los muab qhov tsim nyog hloov tau thiab ua haujlwm ntev. Qhov kev xaiv ntawm cov khoom siv substrate nyob ntawm cov ntawv thov tshwj xeeb, suav nrog qhov kub thiab txias, kev siv lub zog, thiab kev ntseeg tau. Cov ntaub ntawv sib txawv ntawm cov khoom siv sib txawv muaj qhov sib txawv ntawm thermal stability, seem stability, thiab khoov radii, thiab cov no yuav tsum tau ua tib zoo soj ntsuam xyuas kom ntseeg tau tias PCB tuaj yeem tiv taus cov kev ua haujlwm uas nws yuav ntsib.
Lwm qhov kev txiav txim siab tseem ceeb yog cov qauv tsim ntawm cov txheej txheem sib txawv ntawm PCB. Stackup tsim yog hais txog kev npaj ntawm ntau txheej ntawm cov kab hluav taws xob thiab cov khoom siv dielectric hauv PCB.Ua tib zoo npaj cov txheej txheem kev txiav txim, teeb liab routing, thiab lub hwj chim / av dav hlau tso yog ib qho tseem ceeb los xyuas kom meej lub teeb pom kev zoo, electromagnetic compatibility (EMC), thiab thermal tswj. Cov txheej txheem tsim yuav tsum txo qis cov teeb liab sib tham, impedance mismatch, thiab electromagnetic cuam tshuam (EMI) kom lav ntseeg tau thiab ua tau zoo ntawm cov khoom siv hluav taws xob.
Kev sib tw ntawm cov teeb liab thiab lub zog / lub dav hlau hauv av nthuav tawm cov kev cov nyom ntxiv hauv cov txheej txheem ntau yam flex PCBs piv rau cov tsoos nruj PCBs.Qhov yooj yim ntawm cov substrate tso cai rau txoj kab peb sab (3D), uas tuaj yeem txo qhov loj thiab qhov hnyav ntawm cov khoom siv hluav taws xob zaum kawg. Txawm li cas los xij, nws tseem tsim teeb meem hauv kev tswj cov teeb liab kev nthuav tawm qeeb, hluav taws xob hluav taws xob emissions, thiab kev faib hluav taws xob. Cov neeg tsim qauv yuav tsum ua tib zoo npaj txoj hauv kev, xyuas kom raug teeb liab txiav tawm, thiab txhim kho lub zog / hauv av dav hlau faib kom txo qis suab nrov thiab xyuas kom meej cov teeb liab hloov.
Kev tso kawm ntawm cov khoom siv yog lwm qhov tseem ceeb ntawm multilayer flex PCB tsim.Cov txheej txheem txheej txheem yuav tsum xav txog yam xws li qhov chaw txwv, kev tswj xyuas thermal, teeb pom kev ncaj ncees, thiab txheej txheem sib dhos. Cov txheej txheem muab tso rau hauv cov txheej txheem pab txo cov teeb liab txoj kev ntev, txo cov teeb liab kis qeeb, thiab ua kom zoo dua thermal dissipation. Cov khoom loj, kev taw qhia thiab cov yam ntxwv thermal yuav tsum raug txiav txim siab kom ntseeg tau tias muaj cua sov dissipation thiab tiv thaiv overheating nyob rau hauv ntom multilayer qauv.
Tsis tas li ntawd, qhov kev txiav txim siab tsim qauv rau ntau txheej hloov pauv PCBs kuj txuas mus rau cov txheej txheem tsim khoom.Saj zawg zog substrate cov ntaub ntawv, ilv conductive kab, thiab complex thaiv cov qauv yuav tsum tau tshwj xeeb tsim cov txheej txheem. Cov neeg tsim qauv yuav tsum ua haujlwm ze nrog cov tuam txhab tsim khoom kom ntseeg tau tias cov qauv tsim tau sib haum nrog cov txheej txheem tsim khoom. Lawv kuj yuav tsum tau txiav txim siab txog qhov muaj peev xwm tsim khoom, xws li qhov dav qhov dav, qhov tsawg kawg nkaus qhov loj thiab qhov yuav tsum tau ua siab ntev, kom tsis txhob tsim cov teeb meem uas tuaj yeem cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev ntseeg siab ntawm PCB.
Cov kev txiav txim siab tsim qauv tau tham saum toj no qhia txog qhov nyuaj ntawm kev tsim cov txheej txheem sib txawv ntawm PCB.Lawv hais txog qhov tseem ceeb ntawm kev sib koom ua ke thiab cov txheej txheem rau kev tsim PCB, qhov chaw xws li kev xaiv cov khoom siv substrate, stackup tsim, routing optimization, cov khoom tso rau hauv, thiab kev tsim cov txheej txheem kev sib raug zoo tau ua tib zoo soj ntsuam. Los ntawm kev sib koom ua ke cov kev xav no rau hauv theem tsim, cov neeg tsim qauv tuaj yeem tsim cov txheej txheem sib txawv ntawm PCBs uas ua tau raws li cov kev cai nruj ntawm cov khoom siv hluav taws xob niaj hnub no.
Hauv cov ntsiab lus, kev xav txog kev tsim qauv rau ntau cov txheej txheem hloov tau yooj yim PCBs yog qhov tseem ceeb rau kev ua kom ntseeg tau, kev ua haujlwm, thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Kev xaiv cov khoom siv substrate, stackup tsim, routing optimization, kev tso kawm ntawm cov khoom, thiab cov txheej txheem tsim compatibility yog cov tseem ceeb uas yuav tsum tau ua tib zoo soj ntsuam thaum lub sij hawm tsim. Los ntawm kev xav txog cov xwm txheej no, cov neeg tsim qauv tuaj yeem tsim cov txheej txheem sib txawv ntawm PCBs uas muab cov txiaj ntsig ntawm kev txo qhov loj me, txo qhov hnyav, thiab ua kom muaj zog ntxiv, thaum tseem ua tau raws li cov kev cai nruj ntawm cov ntawv siv hluav taws xob niaj hnub no.
