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

Ama-Fecral Alloys kanye nama-Nickel-chromium alloys akhethiwe ukuthi abe yizinto ezimelana ne-resistor eshumekiwe ngenxa yokuthi ama-alloys e-nickel-chromium anokumelana nogesi okuphakeme okusetshenziselwa kakhulu ukumelana nefilimu emincane [1, 2]. Ukumelana neshidi lefilimu ye-nickel-chrome alloy equkethe u-20% we-chromium ingaba phezulu njenge-2-3 kiloohms futhi iqhubeke nokuqina okuhle. I-coefficient yezinga lokushisa engu-1 yokuphikiswa (TCR) yengxube yenqwaba ye-nickel-chrome icishe ibe ngu-110 ppm/°C. Ngokuhlanganisa inani elincane le-silicon ne-aluminium nge-nickel-chromium, ukuzinza kwezinga lokushisa kuyathuthukiswa.

Isicelo:
Ama-resistors ashumekwe ebhodini lezintambo eziphrintiwe azoba amandla okwenza amaphakheji amancane anokwethenjelwa okuphezulu nokusebenza okuthuthukisiwe kukagesi. Ukuhlanganisa ukusebenza kokumelana ne-laminate substrate kukhulula indawo engaphezulu ye-PWB esetshenziswa izingxenye ezihlukene, kunika amandla ukusebenza kwedivayisi okukhulisiwe ngokubeka izingxenye ezisebenza kakhulu. Ama-alloys e-nickel-chromium anokumelana nogesi okuphezulu, okuwenza asebenziseke ekusetshenzisweni okuhlukahlukene. I-nickel ne-chromium ahlanganiswe ne-silicon ne-aluminium ukuze kuthuthukiswe ukuqina kwezinga lokushisa kanye nokwehlisa i-coefficient eshisayo yokumelana. Ungqimba oluncane lwefilimu olumelana nefilimu olususelwe kuma-alloys e-nickel-chromium lufakwe ngokuqhubekayo kumaroli efoyili yethusi ukuze kwakheke izinto ezisetshenziswayo zokumelana nokushumeka. Ungqimba oluncane lwefilimu olumelana nefilimu olufakwe phakathi kwethusi ne-laminate lungaqoshwa ngokukhetha ukuze lwenza izinto eziphikisayo ezihlukene. Amakhemikhali e-etching avamile ezinqubweni zokukhiqiza ze-PWB. Ngokulawula ukushuba kwama-alloys, amanani okumelana neshidi ukusuka ku-25 kuya ku-250 ohm/sq. ziyatholakala. Leli phepha lizoqhathanisa izinto ezimbili ze-nickel-chromium ezindleleni zazo zokunamathisela, ukufana, ukuphatha amandla, ukusebenza okushisayo, ukunamathela kanye nokulungiswa kwe-etching.
