I-1CR133AL4 FECral Alloy Flat Flat Strip / strip ebanzi yokusetshenziswa

I-FECrald Alloys kanye ne-nickel-chromium alloys bakhethwe ukuthi babe yizinto eziphilayo zokumelana nokuphikiswa okushukunyiswayo ngoba ama-nickel-chromium alloys anawo amandla kagesi asetshenziswa kabanzi kwabacijile ngamafilimu [2, 2]. Ukumelana kweshidi kwefilimu ye-nickel-chrome alloy equkethe ama-chromium angama-20% kungaba phezulu njengama-2-3 kilo ohms futhi asalondoloze ukuqina okuhle. I-coefficy yokushisa 1 yokumelana (TCR) ye-Bulk nickel-chrome alloy cishe ngo-110 ppm / ° C. Ngokuqalisa inani elincane le-silicon ne-aluminium nge-nickel-chromium, ukuqina kwezinga lokushisa kuthuthukiswa.

Isicelo:

Ukumelana okufakwe ebhodini le-wiring eliphrintiwe kuzoba yi-Enabler ngamaphakheji amancane ngokuthembela okuphezulu nokusebenza kukagesi okuthuthukisiwe. Ukuhlanganisa ukusebenza kwe-Resistor ku-Linate substrate kukhulula indawo engaphezulu ye-PWB edliwayo okwenziwa yizakhi ze-DWB edliwayo, kunika amandla ukusebenza kwedivaysi okwengeziwe ngokubekwa kwezinto ezisebenzayo. I-nickel-chromium alloys inokumelana kagesi okuphezulu, okubenza basebenze ukuthi basebenzise ezinhlelweni ezahlukahlukene. I-nickel ne-chromium ahlelwe nge-silicon ne-aluminium ukuthuthukisa ukuqina kwezinga lokushisa futhi kwehlise ukumelana okushisayo. Ungqimba oluncane lwefilimu olususelwa ku-nickel-chromium alloys lubekwe ngokuqhubekayo ku-rolls ye-foil yethusi ukudala impahla yezicelo zokuphikisa okushumekiwe. I-sandwich ehlanganisiwe yefilimu ethambile phakathi kwethusi ne-laminate ingangenelwa ngokukhethekile ukuze ikwazi ukumelana nokuphikiswa okungaqondakali. Amakhemikhali e-etching ajwayelekile ezinqubweni zokukhiqiza ze-PWB. Ngokulawula ubukhulu bama-alloys, amanani wokumelana eshidi kusuka ku-25 kuya ku-250 ohm / sq. ziyatholakala. Leli phepha lizoqhathanisa izinto ezimbili ze-nickel-chromium ezindleleni zazo zokugcina, ukufana, ukuphathwa amandla, ukusebenza okushisayo, ukunamathela kanye nokulungiswa kwe-etching.
