Motsoako o khanyang o bataletseng/ o sephara oa 1Cr13Al4 FeCrAl bakeng sa Tšebeliso ea Li-resistor

Li-Alloy tsa Fecral le li-alloy tsa nickel-chromium li khethiloe hore e be thepa e hanyetsang bakeng sa resistor e kenelletsoeng hobane li-alloy tsa nickel-chromium li na le resistivity e phahameng ea motlakase e sebelisoang haholo bakeng sa li-resistors tse tšesaane tsa filimi [1, 2]. Khanyetso ea lakane ea filimi ea alloy ea nickel-chrome e nang le 20% chromium e ka ba holimo ho 2-3 kilo ohms 'me ea ntse e boloka botsitso bo botle. Coefficient ea mocheso oa 1 oa khanyetso (TCR) bakeng sa alloy ea nickel-chrome e kholo ke hoo e ka bang 110 ppm/°C. Ka ho kopanya silicon e nyane le aluminium ka nickel-chromium, botsitso ba mocheso bo ntlafala le ho feta.

Kopo:
Li-resistor tse kentsweng ka hara boto ya terata e hatisitsoeng e tla ba sesebediswa se thusang ho fokotsa dipakete tse nang le tshepahalo e hodimo le tshebetso e ntlafetseng ya motlakase. Ho kopanya tshebetso ya resistor ka hara substrate ya laminate ho lokolla sebaka sa bokahodimo ba PWB se jewang ke dikarolo tse arohaneng, ho nolofalletsa tshebetso e eketsehileng ya sesebediswa ka ho beha dikarolo tse sebetsang haholoanyane. Di-alloy tsa nickel-chromium di na le resistivity e phahameng ya motlakase, e leng se etsang hore di be bonolo ho sebediswa ditshebedisong tse fapaneng. Nickel le chromium di kopantswe ka silicon le aluminium ho ntlafatsa botsitso ba mocheso le ho fokotsa coefficient ya mocheso ya khanyetso. Lera le lesesane la resistance ya filimi le thehilweng hodima di-alloy tsa nickel-chromium le kentswe ka ho tswelang pele hodima meqolo ya foil ya koporo ho etsa thepa bakeng sa ditshebediso tsa resistor tse kentsweng. Lera le lesesane la resistance ya filimi le kentsweng pakeng tsa koporo le laminate le ka kenngwa ka kgetho ho etsa di-resistor tse arohaneng. Dikhemikhale tsa ho kenngwa di atile ditshebetsong tsa tlhahiso ya PWB. Ka ho laola botenya ba di-alloy, boleng ba kganyetso ya lakane ho tloha ho 25 ho isa ho 250 ohm/sq. bo a fumanwa. Pampiri ena e tla bapisa thepa e 'meli ea nickel-chromium mekhoeng ea eona ea ho hlaba, ho tšoana, ho sebetsana le matla, ts'ebetso ea mocheso, ho khomarela le qeto ea ho hlaba.
