P-xim BB hloov pauv tau, feem ntau hu ua Flex PCB, muaj ib tug insulating polyimide zaj duab xis thiab luam tawm Circuit Court qauv. Polyimides yog cov insulators, yog li txoj kev tsuas yog ua tiav yog tias cov qauv Circuit Court yog conductive. Ib yam li “welding mask” ntawm ib lub PCB nruj, lub PCB hloov tau yooj yim yog them nrog nyias “overlay” uas insulates lub Circuit Court los ntawm kev cuam tshuam electromagnetic. Flex PCB tam sim no muaj ntau nyob rau hauv xov tooj ntawm tes thiab kev kho mob, tshwj xeeb tshaj yog thaum cov kev hloov pauv tau hloov pauv qhov kub thiab txias thaum tseem hloov pauv tau.

Flexible PCBS raug suav hais tias yog “hloov” rau ntau yam sib txawv. Qhov pom tseeb tshaj plaws yog tias lawv cov circuitry tuaj yeem hloov kho kom haum rau cov khoom nws tus kheej. Qhov no yog qhov muaj txiaj ntsig tshwj xeeb thaum nws los txog rau qhov ntsuas xws li kev nyob ruaj khov, ruaj khov, qhov hnyav tsawg thiab yoog raws. Cov kab hluav taws xob ib txwm tsis tuaj yeem ua tau raws li cov qauv ntawm kev ua haujlwm ntev, tsis muaj zog thiab ua haujlwm tau zoo.

Flexible boards yog superior rau cov tsoos rigid boards thaum nws los txog rau cov khoom txwv. Piv txwv li, siv lub PCB hloov tau yooj yim es tsis txhob nruj ib qho tuaj yeem txo qhov loj ntawm cov khoom. Lawv tuaj yeem khoov thiab tig los kho rau cov khoom lag luam tseem ceeb. Tag nrho cov khoom tuaj yeem ua kom sib zog siv cov khoom siv tib yam li cov khoom siv nruj thiab hnyav. However, flexible plates are not completely flexible. Cov PCBS no muaj qee qhov chaw nruj, tab sis cov khoom siv hluav taws xob feem ntau tau teeb tsa ntawm qhov hloov pauv tau, yog li nws tuaj yeem hloov kho raws li cov khoom lag luam. Khaws cov khoom siv nruj rau kev txhawb nqa cov khoom yog li nws tau khaws cia rau qib qis tshaj.

1. Kev Siv:

Lub PCB hloov tau yooj yim uas yuav ua tau raws li nws qhov kev nruj yuav raug tsim los ntawm ntau txoj hauv kev. Raws li thev naus laus zis, qib thiab cov khoom siv, peb faib lawv raws li hauv qab no:

Single-sided flexible Circuit Court (SSFC) muaj ib txheej txheej txheej uas muaj cov hlau los yog hlau-filled polymer ntawm ib zaj duab xis dielectric saj zawg zog; Feem ntau polyimide nws siv THT (los ntawm-qhov) mechanism rau mount lub tivthaiv, uas txhais tau hais tias koj siv tau ib sab los kho thiab hloov cov khoom. Ib leeg-ib tog hloov tau PCB nrog lossis tsis muaj cov txheej txheem tiv thaiv tuaj yeem tsim siv cov yeeb yaj kiab insulating; Txawm li cas los xij, kev siv cov txheej thaiv tiv thaiv ntawm lub voj voog yog qhov kev coj ua ntau tshaj plaws vim tias nws tsis muaj zog tiv thaiv Circuit Court thiab ib qho EMI. The structure and insulation of a single-layer flexible PCB are explained as follows:

Sculpted saj zawg zog PCB yog ib qho zoo nkauj subset ntawm saj zawg zog PCB, tam sim no invention muaj feem xyuam rau ib qho yooj yim tsim txoj kev uas tsim ib tug saj zawg zog Circuit Court nrog tooj liab conductors ntawm txawv thickness raws nws ntev. The conductor is thinner in the flexible region and thicker in the rigid region. This method involves selective etching of copper foil to obtain depth in various areas of the circuit.

Engraving saj zawg zog PCB cov txheej txheem yog feem ntau xaiv los tsim liab qab hlau hu ua qhov no ua tau. Ntev los ntawm ntug mus rau qhov txuas txuas. Qhov thaj tsam ntxiv ua rau cov pob qij txha txuas tau ruaj khov thiab ruaj khov dua li cov kev hloov pauv yooj yim.

Multilayer saj zawg zog PCB muaj tib lub voj voog hloov tau nrog ntau txheej. Cov txheej no txuas nrog cov phaj tiaj. Cov txheej txheem ntawm ntau txheej txheej hloov pauv PCB tau txuas ntxiv tsis tu ncua los ntawm qhov. Cov multilayer PCBS no zoo ib yam li PCBS sib tshooj ntau yam tshwj tsis yog hloov pauv hauv cov khoom, qhov zoo, yam ntxwv, thiab tus nqi. Cov txheej txheem hloov pauv tau ntau txheej yog kim dua lawv cov khoom sib xws, tab sis xyuas kom zoo dua qub. Hauv qab no yog kev pom ntawm ntau txheej PCB.

Qhov tsuas yog qhov nruj yog qhov siv rau kev sib koom ua ke. Tus so ntawm lub rooj tsav xwm Circuit Court yog hloov tau.

2. daim ntawv thov:

Saj zawg zog PCBS tau siv hauv cov hauv qab no:

Cov ntawv luam tawm yooj yooj yim feem ntau siv thaum muaj kev ntseeg siab, kev hloov pauv thiab cov khoom siv hnyav, xws li cov khoom siv kho mob. Lub koob yees duab nqos ntsiav tshuaj hu ua Pill Cam siv lub voj voog yooj yim heev uas yuav tsum tau ua kom zoo thiab ruaj khov. Tom qab nqos cov ntsiav tshuaj, cov kws kho mob thiab cov kws tshaj lij tuaj yeem saib cov ntaub so ntswg hauv lub cev kom raug. Cov tshuaj yuav tsum me me thiab yuav tsum txav mus los ntawm lub cev, yog li hloov pauv PCBS yog qhov kev xaiv zoo tshaj plaws, tsis zoo li cov tawv tawv thiab nkig.

B) Smartphones:

Qhov kev thov rau cov xov tooj “ntse” xav tau cov khoom siv txawb los ua los ntawm cov khoom me me thiab hloov tau yooj yim. Yog li, hloov pauv tau PCBS ua lub luag haujlwm tseem ceeb hauv circuits siv nyob rau hauv qee qhov tseem ceeb ntawm Circuit Court, xws li “power amplifiers”. Yog li cov xov tooj tuaj yeem ntse thiab hnav.

C) Computer Electronics:

Cov khoom siv hluav taws xob hauv motherboard yog lub hauv paus thiab tus ntsuj plig ntawm lub computer niaj hnub. Kev tsim hluav taws xob yuav tsum tau ua raws li qhov me me, luv luv. Yog li ntawd, cov khoom siv hluav taws xob hloov pauv tau siv los ua kom txhua yam ruaj khov thiab me me.
