I-1Cr13Al4 FeCrAl alloy Bright Flat Strip/ Wide Strip yokusetshenziswa kwama-Resistors

Ama-Fecral Alloys kanye nama-Nickel-chromium alloys akhethwe ukuba abe yizinto ezivikelayo ze-resistor ehlanganisiwe ngoba ama-nickel-chromium alloys anokumelana okuphezulu kukagesi okusetshenziswa kabanzi kuma-resistors efilimu encane [1, 2]. Ukumelana kweshidi lefilimu ye-nickel-chrome alloy equkethe i-20% chromium kungaba phezulu njenge-2-3 kilo ohms futhi kusalokhu kugcina ukuzinza okuhle. I-coefficient yokushisa 1 yokumelana (TCR) ye-bulk nickel-chrome alloy cishe i-110 ppm/°C. Ngokuhlanganisa inani elincane le-silicon ne-aluminium nge-nickel-chromium, ukuzinza kokushisa kuyathuthukiswa kakhulu.

Isicelo:

Ama-resistors afakwe ebhodini lokuxhuma eliphrintiwe azoba yisivikelo sokwenza amaphakheji amancane abe nokuthembeka okuphezulu kanye nokusebenza kukagesi okuthuthukisiwe. Ukuhlanganisa ukusebenza kwe-resistor ku-substrate ye-laminate kukhulula indawo engaphezulu ye-PWB edliwa yizingxenye ezihlukene, okuvumela ukusebenza okwengeziwe kwedivayisi ngokubeka izingxenye ezisebenzayo kakhulu. Ama-alloy e-nickel-chromium anokumelana okuphezulu kukagesi, okwenza kube lula ukusetshenziswa ezinhlotsheni ezahlukahlukene zokusebenza. I-nickel ne-chromium zixutshwa ne-silicon ne-aluminium ukuthuthukisa ukuzinza kokushisa nokwehlisa i-coefficient yokumelana nokushisa. Ingqimba encane yokumelana nefilimu esekelwe kuma-alloy e-nickel-chromium ibekwe njalo emiqulwini ye-foil yethusi ukudala izinto zokusetshenziswa kwe-resistor ehlanganisiwe. Ingqimba encane yokumelana nefilimu ehlanganisiwe phakathi kwethusi ne-laminate ingaqoshwa ngokukhetha ukuze yakhe ama-resistors ahlukene. Amakhemikhali okuqothula avamile ezinqubweni zokukhiqiza ze-PWB. Ngokulawula ukujiya kwama-alloy, kutholakala amanani okumelana neshidi kusuka ku-25 kuya ku-250 ohm/sq. Leli phepha lizoqhathanisa izinto ezimbili ze-nickel-chromium ezindleleni zazo zokugoba, ukufana, ukuphathwa kwamandla, ukusebenza kokushisa, ukunamathela kanye nesisombululo sokugoba.
