1Cr13Al4 FeCrAl alloy Bright Flat Sawb / Dav Sawb rau Resistor Siv

Fecral Alloys thiab Nickel-chromium alloys tau raug xaiv los ua cov khoom siv tiv thaiv rau embedded resistor vim cov nickel-chromium alloys muaj hluav taws xob tiv taus uas yog dav siv rau nyias zaj duab xis resistors [1, 2].Daim ntawv tsis kam ntawm nickel-chrome alloy zaj duab xis uas muaj 20% chromium tuaj yeem siab li 2-3 kilo ohms thiab tseem muaj kev ruaj ntseg zoo.Qhov kub coefficient 1 ntawm qhov tsis kam (TCR) rau cov nickel-chrome alloy yog li 110 ppm / ° C.Los ntawm alloying me me ntawm silicon thiab txhuas nrog npib tsib xee-chromium, qhov kub thiab txias stability yog ntxiv txhim kho.

Daim ntawv thov:
Resistors embedded nyob rau hauv ib tug luam ntawv hlau board yuav yog ib tug enabler rau miniaturizing tej pob khoom nrog kev ntseeg siab dua thiab txhim kho hluav taws xob kev ua tau zoo.Kev sib koom ua ke ntawm kev ua haujlwm ntawm cov resistor rau hauv laminate substrate frees PWB deg cheeb tsam tau noj los ntawm cov khoom sib cais, ua kom cov cuab yeej ua haujlwm tau zoo los ntawm kev tso cov khoom siv ntau dua.Nickel-chromium alloys muaj hluav taws xob tiv taus siab, uas ua rau lawv siv tau rau ntau yam kev siv.Nickel thiab chromium yog alloyed nrog silicon thiab txhuas los txhim kho qhov kub thiab txias thiab txo cov thermal coefficient ntawm kev ua haujlwm.Ib txheej zaj duab xis nyias nyias raws li cov nickel-chromium alloys tau muab tso rau hauv cov yob ntawm cov ntawv ci tooj liab los tsim cov khoom siv rau kev siv cov khoom siv tiv thaiv.Cov zaj duab xis nyias nyias nyias nyias ntawm cov tooj liab thiab laminate tuaj yeem xaiv tau etched los ua cov resistors discrete.Cov tshuaj rau etching yog muaj nyob rau hauv PWB ntau lawm txheej txheem.Los ntawm kev tswj cov thickness ntawm cov alloys, daim ntawv kuj tseem ceeb ntawm 25 mus rau 250 ohm / sq.tau txais.Daim ntawv no yuav sib piv ob cov ntaub ntawv nickel-chromium hauv lawv cov txheej txheem etching, uniformity, tuav fais fab, thermal ua haujlwm, adhesion thiab etching daws teeb meem.
