1cr13l4 fcral poscral apple strip / strip ballaaran oo loogu talagalay isticmaalka

Foolos Fecral iyo NICKEL-Chromium Alles ayaa loo xushay inay noqdaan walxaha iska caabinta ah ee loo yaqaan 'coisiondy' maxaa yeelay alkomium-ka 'nickel-chromium' oo si weyn loogu isticmaalo iska caabinta filimka fudud [1, 2]. Caabbistu caabbinta filimka Nickel-chrome-chrome-ka oo ay kujiraan 20% chromium waxay noqon kartaa sida ugu badan oo ah 2-3 kilo ohms iyo wali xasillooni wanaagsan. Xanuunka heerkulka 1 ee caabbinta (TCR) ee ugu badan-chrome-chrome-chrome-chrome-chrome waa qiyaastii 110 ppm / ° C. Adigoo dejinaya qadar yar oo silicon ah iyo aluminium leh nickel-chromium, xasilloonida heerkulka ayaa sii kordhaya.

Codsi:
Adkeysiyayaasha ku jira guddiga saqafka daabacan waxay noqon doontaa karti loogu talagalay xirmooyinka milatariziziziz ee leh isku hallaynta iyo isku haleedka sare iyo waxqabadka korantada. Isku-darka shaqeynta ka hortagga substrate-ka meesha lagu soosaaro ayaa xareynaya dusha sare ee PWB ee ay ku cuneen qaybaha Qungagga, meelaynta aaladda ee ku-meel-gaarka ah meelaynta firfircoon. Nasckel-chromium Alles waxay leeyihiin dib u dhac sare oo koronto, kuwaas oo ka dhigaya wax ku ool ah isticmaalka adeegsiyada kala duwan. Nickel iyo Chromium-ka waxaa lagu xardhay silikon iyo alumininium si loo wanaajiyo xasilloonida heerkulka iyo hoos u dhigga kuleylka kuleylka kuleylka. Lakab jilicsan oo jilicsan oo ku saleysan "chromium-ka 'nickel-chromium' ayaa si isdaba joog ah loogu shubaa duubista fashilka naxaas ah si loo abuuro shey loogu talagalay codsiyada loo yaqaan 'aspass'. Filimka khafiifka ah ee loo yaqaan '' Kiimikooyinka cretring-ka ayaa caan ku ah geedi socodka wax soo saarka ee PWB. Adoo xakameynaya dhumucda xudunta, qiimayaasha caabbinta ee xaashida 25 ilaa 250 ohm / sq. waa la helay. Waraaqdani waxay isbarbar dhigi doontaa laba agabnimo oo aan nadiif ahayn oo ku jira hababka cudurka, isku habboonaanta, maaraynta korantada, waxqabadka kuleylka, waxqabadka kuleylka, adhesion iyo hantida xalka.
