Taw qhia
Rigid & flex pcbs tau ua ke nrog cov laug cam kom tsim cov khoom sib xyaw no.Qee cov txheej txheem ntawm cov txheej txheem tsim khoom suav nrog lub voj voog hloov pauv uas khiav los ntawm cov laug cam, zoo li
standard hardboard circuit tsim.
Tus tsim lub rooj tsavxwm yuav ntxiv plated los ntawm qhov (PTHs) uas txuas nruj thiab hloov tau raws li ib feem ntawm cov txheej txheem no.Qhov no PCB tau nrov vim nws txoj kev txawj ntse, raug, thiab hloov tau yooj yim.
Rigid-Flex PCBs ua kom yooj yim rau kev tsim hluav taws xob los ntawm kev tshem cov cables hloov tau yooj yim, kev sib txuas, thiab kev xaim ntawm tus kheej.Rigid & Flex boards circuitry yog nruj dua ua ke rau hauv lub rooj tsavxwm tag nrho cov qauv, uas txhim kho hluav taws xob ua haujlwm.
Cov kws tshaj lij tuaj yeem cia siab tias muaj kev ruaj ntseg zoo dua thiab kev ua tau zoo ntawm hluav taws xob ua tsaug rau qhov nruj-flex PCB cov khoom siv hluav taws xob sab hauv thiab cov khoom siv sib txuas.
Khoom siv
Cov khoom siv substrate
Qhov nrov tshaj plaws nruj-ex tshuaj yog woven fiberglass.Ib txheej tuab ntawm epoxy resin tsho tiv no fiberglass.
Txawm li cas los xij, epoxy-impregnated fiberglass tsis paub tseeb.Nws tsis tuaj yeem tiv taus kev poob siab sai thiab ruaj khov.
Polyimide
Cov khoom no yog xaiv rau nws yooj.Nws muaj zog thiab tuaj yeem tiv taus kev poob siab thiab kev txav.
Polyimide tuaj yeem tiv taus cua sov.Qhov no ua rau nws zoo tagnrho rau kev siv nrog qhov kub thiab txias.
Polyester (PET)
PET yog nyiam rau nws cov yam ntxwv hluav taws xob thiab yooj yim.Nws tiv cov tshuaj thiab dampness.Yog li nws tuaj yeem siv rau hauv kev lag luam hnyav.
Kev siv lub substrate tsim nyog kom ntseeg tau tias xav tau lub zog thiab lub neej ntev.Nws suav nrog cov ntsiab lus xws li kub tsis kam thiab qhov ntev stability thaum xaiv lub substrate.
Polyimide Adhesives
Qhov kub elasticity ntawm cov nplaum no ua rau nws zoo tagnrho rau txoj haujlwm.Nws tuaj yeem tiv taus 500 ° C.Nws cov cua kub tsis kam ua rau nws haum rau ntau yam kev siv tseem ceeb.
Polyester Adhesives
Cov nplaum no yog cov nqi txuag ntau dua li polyimide adhesives.
Lawv yog cov zoo heev rau kev ua kom yooj yim tawg pov thawj circuits.
Lawv txoj kev sib raug zoo kuj tsis muaj zog.Polyester adhesives kuj tsis kub resistant.Lawv tau hloov kho tsis ntev los no.Qhov no muab lawv nrog kub tsis kam.Qhov kev hloov no kuj txhawb kev yoog raws.Qhov no ua rau lawv muaj kev nyab xeeb hauv multilayer PCB los ua ke.
Acrylic Adhesives
Cov nplaum no zoo dua.Lawv muaj thermal stability zoo tiv thaiv corrosion thiab tshuaj.Lawv yog cov yooj yim mus thov thiab kuj pheej yig.Ua ke nrog lawv muaj, lawv yog nrov ntawm manufacturers.manufacturers.
Epoxy
Qhov no yog qhov feem ntau siv nplaum nplaum hauv kev tsim hluav taws xob flex Circuit Court.Lawv tuaj yeem tiv taus corrosion thiab kub thiab qis.
Lawv kuj tsis tshua muaj adaptable thiab adhesively ruaj khov.Nws muaj me ntsis polyester hauv nws uas ua rau nws yooj yim dua.
