1Cr13Al4 FeCrAl aloy Flat Strip/Siidin ballaadhan oo loogu talagalay Isticmaalka caabiyeyaasha

Alloys Fecral iyo Nickel-chromium Alloys ayaa loo doortay inay noqdaan walxaha iska caabbinta ah ee loogu talagalay iska caabbinta ku-xidhan sababtoo ah nikkel-chromium alloys waxay leeyihiin iska caabin koronto oo sarreeya oo si ballaaran loo isticmaalo caabiyeyaasha filimada khafiifka ah [1, 2]. Iska caabbinta xaashida filimka nikkel-chrome alloy ee ka kooban 20% chromium waxay noqon kartaa ilaa 2-3 kilo ohms oo wali waxay ilaalinaysaa xasillooni wanaagsan. Heerkulka 1 ee iska caabinta (TCR) ee daawaynta nikkel-chrome ee bulk waa qiyaastii 110 ppm/°C. Marka la isku daro qadar yar oo silikoon iyo aluminium leh nikkel-chromium, xasiloonida heerkulka ayaa la sii wanaajiyay.

Codsiga:
Iska caabiyayaasha ku dhex jira sabuurada fiilooyinka daabacan waxay noqon doonaan kuwa awood u yeesha yaraynta baakadaha leh isku halaynta sare iyo waxqabadka korantada oo horumaray. Isku-dubbaridka shaqeynta iska-caabista ee substrate-ka laminate-ka ayaa xoreynaya aagga dusha sare ee PWB ee ay cunaan qaybo kala duwan, taas oo awood u siinaysa shaqeynta qalabka oo kordhay iyada oo la meeleynayo qaybo badan oo firfircoon. Alloys-ka nickel-chromium waxay leeyihiin iska caabin koronto oo sarreeya, taas oo ka dhigaysa mid la taaban karo oo loo isticmaalo codsiyo kala duwan. Nikkel iyo chromium waxaa lagu dahaaray silikoon iyo aluminium si loo hagaajiyo xasilloonida heerkulka iyo hoos u dhigista kuleylka kuleylka ee caabbinta. Lakabka khafiifka ah ee filimka khafiifka ah ee ku salaysan nikkel-chromium alloys ayaa si joogto ah loogu shubay duubab bireed naxaas ah si loo abuuro qalab loogu talagalay codsiyada iska caabbinta. Lakabka khafiifka ah ee filimka khafiifka ah ee ku dhex jira naxaasta iyo laminateerka ayaa si xushmad leh loo dhejin karaa si ay u sameeyaan iska caabin kala duwan. Kiimikooyinka loogu talagalay xoqidda waxay ku badan yihiin hababka wax soo saarka PWB. Iyadoo la xakameynayo dhumucda alwaaxyada, qiyamka caabbinta xaashida laga bilaabo 25 ilaa 250 ohm/sq. la helo. Warqadani waxay is barbar dhigi doontaa laba walxood oo nikkel-chromium ah oo ku jira hababka etching, lebbiska, maaraynta awoodda, waxqabadka kulaylka, dhejinta iyo xallinta etching.
