1Cr13Al4 FeCrAl koranu Rīpene Papatahi Kanapa/Rīpene Whānui mō te Whakamahinga Ātete

Kua whiriwhiria ngā koranu Fecral me ngā koranu Nickel-chromium hei rauemi ātete mō te ātete whakauru nā te mea he nui te ātete hiko o ngā koranu nickel-chromium e whakamahia whānuitia ana mō ngā ātete kiriata angiangi [1, 2]. Ka taea e te ātete rau o te kiriata koranu nickel-chrome kei roto ko te 20% chromium te eke ki te 2-3 kiro ohms, ā, ka mau tonu te pumau. Ko te tauwehenga pāmahana 1 o te ātete (TCR) mō te koranu nickel-chrome papatipu he tata ki te 110 ppm/°C. Mā 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 ngā ātete e whakauruhia ana ki roto i te papa waea kua tāia he mea āwhina mō ngā kete iti ake me te pono teitei ake me te mahi hiko pai ake. Mā te whakauru i te mahi ātete ki roto i te papa raima ka wātea te horahanga mata PWB e pau ana i ngā wāhanga motuhake, ka taea ai te whakanui ake i te mahi taputapu mā te whakanoho i ngā wāhanga kaha ake. He teitei te ātete hiko o ngā koranu nikara-konukōmiuma, e whai hua ai mō te whakamahi i roto i ngā momo tono. Ka whakaranua te nikara me te konukōmiuma ki te silicon me te konumohe hei whakapai ake i te pumau o te pāmahana me te whakaiti i te tauwehenga ātete wera. Kua whakatakotoria tonutia he paparanga ātete kiriata angiangi i runga i ngā koranu nikara-konukōmiuma ki runga i ngā rōra pepa parahi hei hanga rauemi mō ngā tono ātete e whakauruhia ana. Ka taea te whakairo tīpako i te paparanga ātete kiriata angiangi i waenganui i te parahi me te raima hei hanga ātete motuhake. He mea noa ngā matū mō te whakairo i roto i ngā tukanga whakaputa PWB. Mā te whakahaere i te matotoru o ngā koranu, ka whiwhihia ngā uara ātete rau mai i te 25 ki te 250 ohm/sq. Ka whakaritea e tēnei pepa e rua ngā rauemi nikara-konukōmiuma i roto i ā rātou tikanga whakairo, te ōritetanga, te whakahaere mana, te mahi wera, te piri me te taumira whakairo.
