Txhim Kho 5mm dav 1Cr13Al4 qaim ca sawb fecral kam kam
1C13al4 Fecral Alloy ci ntsa iab tiaj tus sab Strip / dav Sawb rau cov quab yuam siv
Leclots alloys thiab Nickel-chromium alloys tau raug xaiv rau cov khoom tiv thaiv no uas tau siv hluav taws xob siab rau cov yeeb yaj kiab sib xyaw ua ke [1, 2]. Cov ntawv tiv thaiv Nickel-chrome alloy zaj duab xis muaj txog 20% chromium yuav yog qhov siab li 2-3 kilo ohms thiab tseem tswj kom ruaj khov. Kub Coefficient 1 ntawm kev tiv thaiv (TCR) rau ntau npib tsib xee-chrome alloy yog li 110 ppm / ° C. Los ntawm kev sib dhos ib qho me me ntawm silicon thiab txhuas nrog cov npib tsib xee-chromium, qhov ntsuas kub yog qhov ntxiv ntxiv.
Daim Ntawv Thov:
Cov neeg tawm tsam hauv cov ntawv luam tawm hluav taws xob yuav yog ib qho kev sib koom tes rau cov minimiaturizing pob nrog kev ntseeg siab dua thiab txhim kho hluav taws xob. Kev sib xyaw ua ke resistor kev ua haujlwm rau hauv lub tshav puam frees Nickel-chromium alloys muaj hluav taws xob kub tiv thaiv, uas ua rau lawv ua tau rau kev siv ntau yam kev siv. Npib tsib xee thiab chromium yog txuam nrog silicon thiab txhuas los txhim kho qhov kub thiab txias ruaj khov thiab txo cov thermal coefficient ntawm tsis kam. Ib tug nyias zaj duab xis tiv taus txheej raws li Nickel-chromium alloys tau tso tsis tu ncua los tsim cov khoom siv rau cov ntawv thov deasator. Cov duab zaj duab puab nyias ravestive sandwiched ntawm tooj liab thiab laminate tuaj yeem xaiv etched los ua cov defreitors. Cov tshuaj lom rau etching muaj ntau nyob hauv PWM ntau cov txheej txheem. Los ntawm kev tswj cov tuab ntawm cov alloys, ntawv tiv thaiv qhov tseem ceeb los ntawm 25 txog 250 Ohm / sq. yog tau. Daim ntawv no yuav sib piv ob lub npib tsib xee-chromium-chromium cov ntaub ntawv nyob rau hauv lawv cov txheej txheem etching, kev sib dhos, fais fab kev ua tau, thermal kev ua tau zoo, kev daws teeb meem zoo nkauj thiab etching daws teeb meem.
