1Cr13Al4 FeCrAl huila Bright Flat Strip/Wide Strip no ka hoʻohana ʻana i nā mea pale

Ua koho ʻia ʻo Fecral Alloys a me Nickel-chromium alloys e lilo i mea kū'ē no ka mea pale i hoʻokomo ʻia no ka mea, loaʻa i nā alloys nickel-chromium ka pale pale uila kiʻekiʻe i hoʻohana nui ʻia no nā pale kiʻi ʻoniʻoni lahilahi [1, 2].Hiki ke kiʻekiʻe ke kiʻekiʻe o ka pale o ka nickel-chrome alloy film i loaʻa ka 20% chromium e like me 2-3 kilo ohms a mālama mau i ka paʻa maikaʻi.ʻO ka helu wela 1 o ke kūpaʻa (TCR) no ka nui o ka nickel-chrome alloy ma kahi o 110 ppm/°C.Ma ka hoʻohui ʻana i kahi liʻiliʻi o ke silikoni a me ka alumini me ka nickel-chromium, hoʻomaikaʻi hou ʻia ka paʻa o ka mahana.

Noi:
ʻO nā mea pale i hoʻokomo ʻia i loko o kahi papa uwila i paʻi ʻia he mea hiki ke hoʻonui i nā pūʻolo me ka hilinaʻi kiʻekiʻe a me ka hoʻomaikaʻi ʻana i ka hana uila.ʻO ka hoʻohui ʻana i ka hana resistor i loko o ka laminate substrate e hoʻokuʻu i ka ʻili o ka PWB i hoʻopau ʻia e nā ʻāpana ʻokoʻa, e hiki ai ke hoʻonui i ka hana o ka hāmeʻa ma ke kau ʻana i nā mea ʻoi aku ka ikaika.Loaʻa i nā alloys nickel-chromium ke kūpaʻa uila kiʻekiʻe, kahi e hoʻohana pono ai i nā ʻano hana like ʻole.Hoʻohui ʻia ʻo Nickel a me ka chromium me ke silika a me ka alumini e hoʻomaikaʻi ai i ke kūpaʻa o ka mahana a hoʻohaʻahaʻa i ka coefficient thermal o ke kūpaʻa.Ua waiho mau ʻia kahi ʻāpana pale pale kiʻi lahilahi e pili ana i nā nickel-chromium alloys ma luna o nā ʻōwili keleawe keleawe e hana ai i mea no nā noi pale i hoʻokomo ʻia.Hiki ke kahakaha ʻia ka ʻāpana pale pale kiʻi ʻoniʻoni i hoʻopaʻa ʻia ma waena o ke keleawe a me ka laminate e hana i nā pale kūʻokoʻa.He mea maʻamau nā kemika no ka etching i nā kaʻina hana PWB.Ma ka hoʻomalu ʻana i ka mānoanoa o nā alloys, nā helu pale pale mai 25 a 250 ohm/sq.loaa.E hoʻohālikelike kēia pepa i ʻelua mau mea nickel-chromium i kā lākou mau ʻano etching, like, hoʻohana mana, hana wela, adhesion a me ka hoʻonā etching.
