Wahi noi: Hoʻohana nui ʻia ia i ka umu ʻoihana, nā mea hana hale, ka umu ʻoihana, ka metallurgy, nā mīkini, nā mokulele, ka automotive, ka pūʻali koa a me nā ʻoihana ʻē aʻe e hana ana i nā mea hoʻomehana a me nā mea kū'ē.
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 ke kaohi ʻana i ka mānoanoa o nā mea hoʻoheheʻe, 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.
