Polyimide daim kab xev, tseem hu ua Kapton daim kab xev, yog ntau yam hluav taws xob rwb thaiv tsev thiab txheej zaj duab xis feem ntau siv hauv ntau daim ntawv thov. Nws yog cov khoom siv xim amber-xim uas ua raws li cov khoom siv hluav taws xob zoo heev, yog nyias thiab ua tau zoo, thiab muaj lub zog tsim kua muag ntawm qhov kub siab.
Nws feem ntau siv los ua lwm txoj hauv kev rau cov qauv tooj liab-clad ntawv ci thiab nyiaj npog zaj duab xis hauv yoj soldering ntawm cov ntawv luam tawm Circuit Board (PCB) thaum lub sijhawm tsim khoom. Nws kuj tseem ua haujlwm ua lub ntsej muag kub kub rau cov hmoov txheej thiab tuaj yeem siv rau cov chaw hlau thaum lub sij hawm e-txheej, electroplating, anodizing, thiab lwm yam txheej txheem uas yuav tsum tau muaj cov txheej txheem kub-resistant.
Qhov zoo tshaj plaws yog tias nws tuaj yeem siv nrog lub siab tsawg, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev thov rau qhov muag muag. Nws kuj tseem muaj zog heev thiab tiv taus qhov kub txog li 500degC / 260degF, yog li nws yog qhov zoo rau cov ntawv thov uas yuav tsum tau kub hnyiab.
Muaj ntau ntau hom polyimide daim kab xev, tab sis feem ntau yog ua los ntawm polyimide zaj duab xis, coated nrog silicone nplaum los yog acrylic nplaum, thiab tsim rau high-temperature hluav taws xob daim ntaub ntawv.
Kapton yog ib lub npe nrov tshaj plaws ntawm polyimide zaj duab xis thiab tau ua cov khoom ntawm kev xaiv rau ntau lub dav hlau thiab lwm yam kev lag luam aerospace, suav nrog New Horizons thiab James Webb spacecraft. Nws kuj yog siv los ua ib qho aluminized thermal insulator hauv cov motors thiab transformers, kom ntseeg tau tias cov khoom siv hluav taws xob tsis kub dhau lossis txias dhau.
Polyimide yog cov khoom siv ruaj khov, cov khoom siv thermoplastic uas muaj tshuaj lom neeg, tiv taus cov kua qaub thiab roj, thiab khaws cov khoom siv hluav taws xob ntawm qhov kub thiab txias. Qhov no tso cai rau cov khoom siv hluav taws xob tuaj yeem kuaj xyuas, kuaj, kho, thiab kho dua.
Feem ntau, polyimide yog laminated nrog nyias txheej ntawm txhuas los yog lwm yam ntaub ntawv los ua kom nws tiv taus kub hloov thiab kev co. Qhov no ua rau nws yog ib qho khoom siv zoo heev rau kev tiv thaiv lub dav hlau los ntawm lub hnub UV rays thiab ua kom cov khoom siv hluav taws xob tiv thaiv los ntawm lwm yam kev mob hnyav.
Nws tuaj yeem siv rau ntau yam khoom sib txawv thiab tuaj yeem tiv taus qhov kub txog li 400degC / 572degF yam tsis muaj zog lossis poob nws lub zog nplaum. Kev puas tsuaj thiab tsim kua muag ntawm daim kab xev yog qhov zoo heev, uas feem ntau yog siv los qhwv coils hauv lub tshuab hluav taws xob thiab ua interlayer rwb thaiv tsev rau transistors thiab lwm yam khoom siv hluav taws xob ntawm 3D luam ntawv.
Kuj tseem muaj lwm cov ntaub ntawv ntawm aluminized polyimide, xws li cov uas muaj hlau oxide tiav. Lawv muab cov khoom zoo sib xws li aluminized polyimide tab sis nyob rau hauv ib daim ntawv softer, hloov tau yooj yim dua uas yooj yim rau kev tswj xyuas.
Cov yeeb yaj kiab polyimide yog txhawb nqa los ntawm cov nplaum silicone uas ua rau lubpolyimide daim kab xevkom tiv taus qhov kub txog li 260degC / 500degF, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv kub thiab hluav taws xob. Nws tuaj yeem siv rau ntau yam substrates, suav nrog hlau, yas, thiab txawm iav.
