I-1Cr13Al4 FeCrAl alloy Bright Flat Strip/ Wide Strip yokusetyenziswa kweResistors

IiFecral Alloys kunye neeNickel-chromium alloys zikhethwe ukuba zibe zizinto ezikhuselayo kwi-resistor efakwe kuba ii-nickel-chromium alloys zine-electrical resistivity ephezulu esetyenziswa kakhulu kwi-thin film resistors [1, 2]. Ukumelana kweshiti kwefilimu ye-nickel-chrome alloy equlethe i-20% chromium kunokuba phezulu njenge-2-3 kilo ohms kwaye kusagcinwe uzinzo oluhle. I-temperature coefficient 1 of resistance (TCR) ye-bulk nickel-chrome alloy imalunga ne-110 ppm/°C. Ngokudibanisa inani elincinci le-silicon kunye ne-aluminium kunye ne-nickel-chromium, uzinzo lobushushu luphuculwa ngakumbi.

Isicelo:
Iiresistor ezifakwe kwibhodi yocingo eprintiweyo ziya kuba luncedo ekwenzeni iipakethe zibe ncinci ngokuthembeka okuphezulu kunye nokusebenza kombane okuphuculweyo. Ukudibanisa ukusebenza kweresistor kwi-substrate ye-laminate kukhulula indawo yomphezulu we-PWB esetyenziswa zizinto ezihlukeneyo, okuvumela ukusebenza kwesixhobo okwandisiweyo ngokubekwa kwezinto ezisebenzayo ngakumbi. Ii-alloy ze-nickel-chromium zinokumelana okuphezulu kombane, okwenza ukuba zibe luncedo ekusebenziseni kwiintlobo ngeentlobo zezicelo. I-nickel kunye ne-chromium zixutywe nge-silicon kunye ne-aluminium ukuphucula uzinzo lobushushu kunye nokunciphisa i-coefficient yobushushu yokumelana. Umaleko omncinci wefilimu osekelwe kwi-alloy ze-nickel-chromium ubekwe rhoqo kwimiqulu yefoyile yobhedu ukwenza izinto zokusetyenziswa kwe-resistor efakwe ngaphakathi. Umaleko omncinci wefilimu oncitshisiweyo phakathi kobhedu kunye ne-laminate unokunqunyulwa ngokukhetha ukwenza iiresistor ezihlukeneyo. Iikhemikhali zokunqunyulwa zixhaphakile kwiinkqubo zemveliso ye-PWB. Ngokulawula ubukhulu bee-alloy, amaxabiso okumelana neshiti ukusuka kwi-25 ukuya kwi-250 ohm/sq. afunyanwa. Eli phepha liza kuthelekisa izinto ezimbini ze-nickel-chromium kwiindlela zazo zokugrumba, ukufana, ukuphathwa kwamandla, ukusebenza kobushushu, ukunamathela kunye nesisombululo sokugrumba.
