1cr13al4 FOCRART ALOML FRAT FRIP / RIP YAMIP YAMISTI YOPHUNZITSIRA

Malumi a nthol and Neckel-chromial onlos asankhidwa kuti akhale chinthu chotsutsana ndi zotsutsana ndi zotsutsana ndi zikwangwani zamagetsi zomwe zimagwiritsidwa ntchito ndendende zamagetsi omwe amagwiritsidwa ntchito ngati filimu yopyapyala (1, 2]. Chotsani pepala la nickel-chromel-chromel alloy lomwe lili ndi 20% chromium ikhoza kukhala yokwera ngati 2-3 a soms ndikukhazikikabe. Kutentha kwa kutentha 1 kwa kukana (TCR) ya Chuma bilth Nicmel-chrome-cromel ndi pafupifupi 110 ppm / ° C. Mwa kupereka gawo laling'ono la silicon yaying'ono ndi aluminiyamu ndi nickel-chromium, kutentha kutentha kumakhalanso bwino.

Ntchito:

Omangidwa m'matumbo osindikizidwa adzapatsidwa mwayi kwa mapaketi otsika ndi kudalirika kwapamwamba komanso magetsi oyenda bwino. Kuphatikiza zomwe zimapangitsa kuti ntchito zigwirizane mu malo a lamite imamasula malo a PWB pamwamba pa zigawo zikuluzikulu, zomwe zimathandizira kuchuluka kwa chipangizo chogwirira ntchito ndi malo ogwirira ntchito. Nickel-chromiyal olosi omwe ali ndi mavuto ambiri amagetsi, omwe amawapangitsa kuti azigwiritsa ntchito pazogwiritsa ntchito zosiyanasiyana. Nickel ndi chromium amayandikana ndi silicon ndi aluminiyamu kuti azitha kusintha kutentha ndikutsitsa mphamvu yopatsa mphamvu yakukana. Kanema wopyapseza wozungulira wa Nickel-Cromium Snows adayikidwa mosalekeza pa masikono a zojambula zamkuwa kuti apange zinthu zotsutsana. Kanema woonda wopindika pakati pa mkuwa ndipo laminate amatha kukhala osankha mokhazikika kuti apange chipongwe. Mankhwala opanga etch ndiofala njira zopangira pwb. Mwa kuwongolera makulidwe a oversys, kuthetsa mapepala kuchokera ku 25 mpaka 250 ohm / sq. amapezeka. Pepala ili likufanizira zida ziwiri-chromium mu njira zawo zadzikoling m'njira, kufanana, kugwiritsa ntchito mphamvu, zotsatsa, zomatira ndi kutanthauzira.
