Daim Ntawv Thov Cheeb Tsam: Nws yog dav siv nyob rau hauv industrial furnace, khoom siv hauv tsev, kev lag luam rauv, metallurgy, machinery, aircraft, automotive, tub rog thiab lwm yam industries ua cua sov ntsiab thiab kuj ntsiab.

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.
