1Cr13Al4 FeCrAl koranu Wehe Papatahi Maama/ Wea Whanui mo te Whakamahi Paearu

Ko te Fecral Alloys me te Nickel-chromium alloys kua tohua hei rauemi parenga mo te parenga whakauru na te mea he nui te parenga hiko e whakamahia ana mo nga parenga kiriata angiangi [1, 2]. Ko te parenga pepa o te kiriata koranu nickel-chrome kei roto 20% chromium ka taea te teitei ki te 2-3 kiro ohm me te pupuri tonu i te pai. Ko te whakarea pāmahana 1 o te parenga (TCR) mo te nuinga o te nickel-chrome alloy he 110 ppm/°C. Ma te whakakotahi i te iti o te silicon me te konumohe me te nickel-chromium, ka pai ake te pumau o te pāmahana.

Taupānga:
Ko nga parenga kua mau ki roto i te papa waea kua taia hei whakaahei mo te whakaiti i nga kohinga me te pono ake me te pai ake o te mahi hiko. Ko te whakauru i te mahi parenga ki roto i te tïpako laminate ka wetekina te mata o te PWB i pau i nga waahanga motuhake, ka taea te whakanui ake i te mahi taputapu ma te whakaurunga o nga waahanga kaha ake. Ko nga koranu nickel-chromium he nui te parenga hiko, na reira ka taea te whakamahi i roto i nga momo tono. Ko te Nickel me te chromium ka whakakotahi ki te silicon me te konumohe hei whakapai ake i te pumau o te pāmahana me te whakaheke i te whakarea wera o te aukati. He paparanga parenga kiriata angiangi i runga i nga koranu nickel-chromium kua tukuna tonu ki runga i nga roera konumohe parahi hei hanga rauemi mo nga tono parenga whakauru. Ko te paparanga whakaatete kiriata angiangi e mau ana i waenganui i te parahi me te laminate ka taea te tarai maataki hei hanga parenga motuhake. Ko nga matū mo te tarai he mea noa i roto i nga tukanga whakaputa PWB. Ma te whakahaere i te matotoru o nga koranu, nga uara parenga pepa mai i te 25 ki te 250 ohm/sq. ka whiwhi. Ka whakatairitehia e tenei pepa nga rauemi nickel-chromium e rua i roto i o raatau tikanga tarai, te rite, te whakahaere hiko, te mahi waiariki, te piri me te whakataunga tarai.
