Muaj ob hom conductive adhesives siv los txuas electrodes thiab sab nraud circuits: ① thermal drying type; ② thermal curing hom Q thermal curing hom conductive nplaum feem ntau yog hom epoxy, thiab nws qhov kub thiab txias yog li 90 ~ 15 (TC. Cia siab tias yuav tsim nyob rau yav tom ntej Qhov kub kub curing conductive nplaum yog nyob ib ncig ntawm 70 ~ 80T. Lub ziab kub ntawm thermal ziab conductive nplaum yog tsuas yog 120T, thiab qhov kub thiab txias yog qis dua 120T kuj tseem siv tau, tab sis xav txog qhov hloov pauv viscosity thiab clogging ntawm cov txheej txheem luam ntawv, nws yog qhov zoo dua los siv 1201 ntawm.
Cov khoom ntawm conductive nplaum siv hauv kev tshuaj ntsuam luam ntawv. Cov yam ntxwv tseem ceeb yuav tsum tau luam tawm viscosity, curing tej yam kev mob, kab tsis kam, thiab adhesion rau lub substrate. Tsis tas li ntawd, nyob ntawm daim ntawv thov, ntau yam yuav tsum tau muaj xws li hardness thiab dabtsi yog khoov kuj yuav tsum tau. Ntxiv nrog rau cov yam ntxwv tseem ceeb ntawm cov nplaum nplaum rau cov ntxaij vab tshaus kov, nws kuj xav tau qee cov yam ntxwv uas phim ITO zaj duab xis.
Vim tias sab saum toj electrode ntawm cov tshuaj tiv thaiv kov siv ITO zaj duab xis, nws qhov kub yuav tsum qis dua 150 taw, thiab qhov kub zoo tshaj plaws yog qis dua 120 feet. Tsis ntev los no, nyias zaj duab xis substrates nrog cov cua kub qis dua li PET tau siv, yuav tsum tau kho qhov kub thiab txias. Cov khoom tsim nyog tshaj plaws yog AF4820, uas tuaj yeem kho tau ntawm 90T. Txij li thaum lub hauv qab electrode yog tsim nyob rau hauv lub iav substrate, nws tsis yog tsim nyog los ua ib tug tsawg-kub txheej txheem. Txawm li cas los xij, tsis ntev los no, ITO cov yeeb yaj kiab kuj tau siv rau hauv qab electrode. Nws tuaj yeem pom tias qhov ua tau ntawm kev siv cov nplaum nplaum uas tuaj yeem kho tau ntawm qhov kub thiab txias yuav nce ntxiv rau yav tom ntej.
Hauv cov ntxaij vab tshaus kov, nws yog qhov tseem ceeb heev los txhim kho qhov adhesion ntawm ITO zaj duab xis thiab cov nplaum nplaum, uas yog, txhawm rau txhim kho kev ruaj ntseg ntawm kev sib cuag ntawm cov nplaum nplaum thiab ITO zaj duab xis. Hauv cov ntxaij vab tshaus kov, kev hloov pauv hauv kev sib cuag ntawm cov nplaum nplaum thiab ITO zaj duab xis yuav ua rau kev ua haujlwm tsis zoo.
Kev hloov pauv ntawm kev tiv thaiv kev tiv thaiv thiab nws qhov sib txawv muaj qhov cuam tshuam zoo rau kev ua haujlwm ntawm lub vijtsam kov. Nws tuav cov conductivity nyob rau hauv Z-axis kev taw qhia thiab txo cov residual stress ntawm ITO zaj duab xis. Lub rhiab heev ntawm cov conductive nplaum yog nruj heev.
Piv nrog rau yav dhau los cov nplaum nplaum, AF5000 tshwj xeeb tsim los daws qhov kev tiv thaiv tiv thaiv nrog ITO zaj duab xis. Kom paub meej, nws tiv thaiv kev tiv thaiv nrog ntau yam ITO films yog qhov ruaj khov. Yog li ntawd, qhov sib txuam ntawm cov nplaum nplaum thiab ITO zaj duab xis yog qhov tseem ceeb hauv kev xaiv cov nplaum nplaum. Hauv kev tshuaj ntsuam kov, ITO zaj duab xis txiav txim siab cov yam ntxwv kho qhov muag ntawm cov khoom, yog li nws yog qhov yuav tsum tau xaiv cov nplaum nplaum uas phim rau ITO zaj duab xis. Ua ntej no, cov substrates nrog ITO zaj duab xis feem ntau yog PET. Xav txog cov khoom siv kho qhov muag thiab cov yam ntxwv saum npoo ntawm cov substrates, kev siv cov ntaub ntawv xws li polycarbonate (PC) rau substrates tau maj mam nce. Tus sau ntseeg tias qhov tseem ceeb ntawm kev xaiv cov khoom siv nplaum nplaum yog qhov sib txuam ntawm cov khoom siv thiab cov yeeb yaj kiab ITO.
Lub adhesion ntawm conductive nplaum yog ib txoj hauv kev yooj yim los ntsuas qhov sib txuam ntawm cov nplaum nplaum thiab ITO zaj duab xis.
Raws li cov txheej txheem kho ntawm cov nplaum nplaum thiab ITO zaj duab xis hloov, cov adhesion kuj hloov. Tsis tas li ntawd, qhov tev tawm tsis yog tsuas yog qhov cuam tshuam ntawm cov yeeb yaj kiab conductive thiab ITO zaj duab xis, tab sis kuj yog qhov cuam tshuam ntawm ITO zaj duab xis thiab cov substrate nyob rau hauv qee kis. Yog li ua tib zoo saib thaum ntsuas. Qhia cov txiaj ntsig ntawm kev kuaj adhesion tom qab txheej txheej insulating yog tsim rau ntawm cov nplaum nplaum. Txawm hais tias lub adhesion ntawm conductive nplaum ib leeg yog zoo heev, nws adhesion yuav raug txo thaum lub insulating txheej yog tsim los ntawm conductive nplaum. Qee qhov piv txwv tau lees paub tias kev siv cov txheej txheem insulating yuav cuam tshuam rau qhov adhesion ntawm conductive nplaum rau ITO zaj duab xis.
