1Cr13Al4 FeCrAl alloy Bright Flat Strip / Wide Strip bakeng sa Tšebeliso ea Resistors

Li-alloys tsa Fecral le li-alloys tsa Nickel-chromium li khethiloe hore e be thepa e hanyetsang bakeng sa mohanyetsi o kentsoeng hobane li-alloys tsa nickel-chromium li na le matla a phahameng a matla a motlakase a sebelisoang haholo bakeng sa lihanyetsi tse tšesaane tsa lifilimi [1, 2]. Letlapa la khanyetso ea filimi ea alloy ea nickel-chrome e nang le 20% chromium e ka ba holimo ho 2-3 kilo ohms mme e ntse e boloka botsitso bo botle. Thempereichara ea 1 ea ho hanyetsa (TCR) bakeng sa alloy e ngata ea nickel-chrome e ka ba 110 ppm/°C. Ka ho kopanya silicon le aluminium e nyenyane ka nickel-chromium, botsitso ba mocheso bo ntse bo ntlafala.

Kopo:
Li-resistors tse kentsoeng ka har'a boto e hatisitsoeng ea wiring e tla ba sesebelisoa sa ho etsa liphutheloana tse nyane tse nang le ts'epo e phahameng le ts'ebetso e ntlafalitsoeng ea motlakase. Ho kopanya ts'ebetso ea ho hanyetsa ka har'a substrate ea laminate ho lokolla sebaka sa PWB se sebelisoang ke likarolo tse sa tšoaneng, se nolofalletsang ho eketsa ts'ebetso ea lisebelisoa ka ho behoa ha likarolo tse sebetsang haholoanyane. Li-alloys tsa nickel-chromium li na le matla a phahameng a ho hanyetsa motlakase, e leng se etsang hore li sebetse ho sebelisoa lits'ebetsong tse fapaneng. Nickel le chromium li kopantsoe le silicon le aluminium ho ntlafatsa botsitso ba mocheso le ho theola coefficient ea mocheso oa ho hanyetsa. Lera le tšesaane le hanyetsanang le filimi le thehiloeng holim'a li-alloys tsa nickel-chromium le kentsoe khafetsa holim'a meqolo ea foil ea koporo ho etsa lisebelisoa bakeng sa lisebelisoa tse kentsoeng tsa resistor. Lesela le tšesaane la ho hanyetsa filimi le kentsoeng lipakeng tsa koporo le laminate le ka hlophisoa ka mokhoa o ikhethileng ho etsa lihanyetsi tse ikhethileng. Lik'hemik'hale tsa etching li tloaelehile lits'ebetsong tsa tlhahiso ea PWB. Ka ho laola botenya ba li-alloys, litekanyetso tsa ho hanyetsa lakane ho tloha ho 25 ho isa ho 250 ohm / sq. lia fumanoa. Pampiri ena e tla bapisa lisebelisoa tse peli tsa nickel-chromium ka mekhoa ea tsona ea etching, ho ts'oana, ts'ebetso ea matla, ts'ebetso ea mocheso, ho khomarela le ho etsa qeto.
