Flexible ca cable (FFC) yog lub teeb liab xaim hluav taws xob uas siv dav hauv cov khoom siv hluav taws xob, tsheb hluav taws xob, khoom siv kho mob, thiab lwm yam. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv nws qhov kev hloov pauv siab, kev cog lus hneev taw, thiab khoov tau, tag nrho cov uas muaj feem cuam tshuam nrog kev xaiv ntawm nws cov khoom tseem ceeb.
Cov ntaub ntawv tseem ceeb ntawm FFC yog tus neeg xyuas pib, txheej rwb thaiv tsev, thiab cov ntaub qhwv. Tus neeg xyuas pib feem ntau yog ua los ntawm siab -purity electrolytic tooj liab lossis tinned tooj liab. Electrolytic tooj liab muaj cov conductivity zoo heev, ua kom ruaj khov teeb liab kis tau tus mob thiab poob qis; tinned tooj liab muaj kev txhim kho oxidation tsis kam, ua rau nws haum rau ib puag ncig raug huab cua rau lub sij hawm ntev, txuas rau cable txoj kev pab cuam lub neej. Lub thickness thiab dav ntawm tus neeg xyuas pib cuam tshuam ncaj qha rau cable tam sim no - nqa lub peev xwm thiab hloov tau yooj yim, thiab yog li xav tau kev tsim kho kom zoo raws li cov ntawv thov tshwj xeeb scenario.
Cov txheej rwb thaiv tsev yog ib qho tseem ceeb ntawm FFC thiab feem ntau yog ua los ntawm polyimide (PI) lossis polyester (PET) zaj duab xis. Polyimide muaj qhov tshwj xeeb kub kub ua haujlwm (ntev- lub sijhawm ua haujlwm kub siab tshaj 200 degree), lub zog ntawm lub zog, thiab tshuaj lom neeg ruaj khov, ua rau nws tsim nyog rau cov khoom siv hluav taws xob ua haujlwm hauv siab - qhov kub thiab txias, xws li aerospace thiab kev lag luam tswj. Polyester, ntawm qhov tod tes, muab tus nqi qis dua thiab hloov tau yooj yim dua, ua rau nws tsim nyog rau cov neeg siv khoom siv hluav taws xob, tab sis nws cov cua sov kuj tsis muaj zog (feem ntau tsis siab tshaj 150 degree). Lub thickness ntawm cov txheej rwb thaiv tsev cuam tshuam ncaj qha rau cable cov rwb thaiv tsev kev ua tau zoo thiab tag nrho cov kev yooj yim, yuav tsum muaj qhov sib npaug ntawm cov hluav taws xob thiab cov khoom siv kho tshuab.
Tsis tas li ntawd, qee qhov siab -FFCs suav nrog cov ntaub qhwv ntxiv, xws li polyvinyl chloride (PVC) lossis thermoplastic elastomer (TPE), hla txheej rwb thaiv tsev kom muab cov khoom tiv thaiv ntxiv, tensile zog, thiab kev tiv thaiv ib puag ncig. PVC sheathing muaj qhov yooj yooj yim thiab tshuaj tiv thaiv, ua rau nws haum rau kev lag luam ib puag ncig; thaum TPE yog ib puag ncig zoo dua qub thiab muaj kev tiv thaiv huab cua zoo dua qub, ua rau nws tsim nyog rau kev siv sab nraum zoov lossis cov ntawv thov uas xav tau cov khoom siv siab, xws li cov khoom siv kho mob.
Hauv cov ntsiab lus, cov khoom siv tseem ceeb rau kev hloov pauv ntawm cov cables ncaj qha cuam tshuam rau lawv cov conductivity, yooj, kub tsis kam, thiab kev pabcuam lub neej. Los ntawm kev sib xyaw ua ke tooj liab conductors, polyimide lossis polyester rwb thaiv tsev txheej, thiab cov ntaub ntawv sheath tsim nyog, FFC tuaj yeem ua tiav cov teeb liab zoo thiab ruaj khov hauv ntau qhov chaw hnyav, ua tau raws li cov kev xav tau ntawm cov khoom siv hluav taws xob niaj hnub no rau miniaturization thiab kev ntseeg siab.
