Thin Film vs Thick Film Resistors
Nyias zaj duab xis resistors thiab tuab zaj duab xis resistors yog ob hom resistors uas siv rau hauv hluav taws xob thiab hluav taws xob circuits. Lub resistor yog ib qho khoom siv uas siv los "tiv thaiv" qhov ntws ntawm tam sim no vim muaj qhov hluav taws xob. Nyias thiab tuab zaj duab xis resistors yog siv nyob rau hauv daim ntaub ntawv xws li nto mount li. Kev nkag siab zoo hauv cov resistors yog xav tau hauv kev lag luam xws li electronics, process engineering thiab electronic parts manufacturing. Hauv tsab xov xwm no, peb yuav sib tham, sib piv, thiab sib txawv cov yeeb yaj kiab tuab thiab nyias zaj duab xis resistors. Cov kab lus yuav hais txog dab tsi tuab zaj duab xis resistors thiab nyias zaj duab xis resistors yog, yuav ua li cas tuab zaj duab xis resistors thiab nyias zaj duab xis resistors yog tsim, daim ntaub ntawv ntawm tuab zaj duab xis thiab nyias zaj duab xis resistors, cov ntaub ntawv siv los tsim cov zaj duab xis tuab thiab nyias zaj duab xis resistors, cov khoom ntawm tuab zaj duab xis thiab nyias zaj duab xis resistors, lawv zoo sib xws, thiab thaum kawg qhov sib txawv ntawm tuab zaj duab xis resistors thiab nyias zaj duab xis resistors.
Ib zaj duab xis resistors yog dab tsi?
Yuav kom nkag siab txog cov yeeb yaj kiab nyias nyias yuav tsum xub nkag siab tias qhov resistor yog dab tsi. Kev tiv thaiv yog ib qho cuab yeej tseem ceeb hauv kev lag luam hluav taws xob thiab hluav taws xob. Qhov kev tawm tsam hauv cov ntsiab lus zoo qhia peb tias nws nyuaj npaum li cas rau qhov hluav taws xob ntws. Hauv kev txiav txim siab ntau, qhov kev tawm tsam ntawm ob lub ntsiab lus tuaj yeem txhais tau tias yog qhov sib txawv ntawm qhov voltage uas yuav tsum tau coj ib chav tsev tam sim no hla ob lub ntsiab lus. Hluav taws xob tsis kam yog qhov hloov pauv ntawm hluav taws xob conduction. Qhov kev tiv thaiv ntawm ib qho khoom yog txhais tau tias yog qhov piv ntawm qhov hluav taws xob thoob plaws qhov khoom mus rau qhov tam sim no ntws los ntawm nws. Resistor yog cov cuab yeej siv los ua kom tau txais kev tiv thaiv. Txhua yam khoom nyob rau hauv lub neej muaj ib tug finite tus nqi ntawm kuj. Nyias zaj duab xis resistors yog tsim los ntawm cov txheej txheem ntawm sputtering cov khoom resistive ntawm cov ceramic. Tom qab ntawd qhov saum npoo yog etched siv ultraviolet raug thiab tsim nyog etching txoj kev. Cov ntaub ntawv siv nyob rau hauv nyias zaj duab xis resistors yog tantalum nitride, bismuth ruthnate, ruthenium oxide, lead oxide thiab nickel chromium. Cov etched zaj duab xis ces trimmed siv lasers.
Cov zaj duab xis tuab yog dab tsi?
Thick film resistors, raws li lawv lub npe qhia, muaj cov yeeb yaj kiab tuab dua li cov yeeb yaj kiab nyias nyias. Thick film resistors yog tsim los siv tib lub tebchaw. Tab sis cov txheej txheem ntawm cov yeeb yaj kiab tuab yog txawv ntawm cov yeeb yaj kiab nyias. Lub tuab zaj duab xis resistor yog tsim los ntawm kev sib xyaw cov tshuaj tiv thaiv nrog cov hmoov iav thiab cov kua ua kua. Qhov sib tov yog tshuaj ntsuam luam tawm rau ceramic. Tom qab ntawd cov khoom yog ci ntawm 850 degrees Celsius, kom khov lub khob.
Dab tsi yog qhov txawv ntawm Thin Film Resistors thiab Thick Film Resistors?
• Nyias zaj duab xis resistors muaj qhov ua siab ntev dua li cov yeeb yaj kiab tuab.
• Lub peev xwm ntawm nyias zaj duab xis resistors yog qis dua li ntawm cov yeeb yaj kiab tuab.
• Qhov kub coefficient ntawm nyias zaj duab xis resistors yog qis dua li ntawm cov zaj duab xis tuab resistors.
• Kev tsim cov yeeb yaj kiab nyias nyias yog kim dua tus nqi tsim tawm ntawm cov yeeb yaj kiab tuab.
• Cov txheej txheem ntawm kev tsim cov yeeb yaj kiab nyias nyias txawv ntawm cov txheej txheem tsim cov yeeb yaj kiab tuab.
