Etchant

Papa Kaula

Hōʻike huahana

Hoʻohana nui ʻia ʻo Etchant (etchant) i ka hana metala, ka hana semiconductor, ka hana ʻenehana uila, ka hana chip a me ka noiʻi ʻepekema. I ka hana metala, hoʻohana ʻia nā etchants e wehe i nā oxides a i ʻole nā ​​​​mea i makemake ʻole ʻia mai nā ʻili metala, e hoʻomaikaʻi ai i ka maikaʻi a me nā ʻano o nā ʻāpana metala. I ka hana semiconductor a me ka uila, hoʻohana ʻia nā etchants e hana i nā hale liʻiliʻi a me nā kaʻa. Ma ke kahua o ka noiʻi ʻepekema, hiki ke hoʻohana ʻia nā etchants e hoʻomākaukau i nā laʻana e nānā i kā lākou microstructure. I ka hōʻuluʻulu ʻana, loaʻa i nā etchants nā noi koʻikoʻi ma nā kahua he nui.

Ma ke kaʻina hana semiconductor, ʻo Etchant kahi hopena kemika i hoʻohana ʻia e hana i ka etching kūloko ma nā chips a me nā mea hana semiconductor ʻē aʻe. Hoʻohana ʻia kēia etching e hana i nā hale liʻiliʻi e like me nā ala a me nā vias e wehewehe i ka circuitry o ka chip a me nā hiʻohiʻona ʻē aʻe. ʻO ka maʻamau, hoʻohana ʻia ʻo Etchant i nā wahi kikoʻī o kahi hāmeʻa semiconductor, ma o ka ʻenehana masking a i ʻole nā ​​ala ʻē aʻe, i mea e hoʻokō ai i nā hiʻohiʻona a me nā hale i makemake ʻia. Hiki ke hoʻololi ʻia ka hohonu a me ka pololei o ka etching ma ke kāohi ʻana i ka haku mele ʻana o Etchant, ka mahana a me ka manawa etching. No laila, i ke kaʻina hana semiconductor, ʻo Etchant kahi mea hana koʻikoʻi i hoʻohana ʻia e wehewehe a hana i nā hale maikaʻi ma ka chip.

Hoʻohana mau ʻia ka Etchant (etchant) no ka hana ʻana i nā papa kaapuni i paʻi ʻia (PCB) i ka wā e hana ana i nā mea uila, ʻoi aku hoʻi i nā kaʻina etching kemika. ʻO kāna hana ʻo ka wehe ʻana i nā ʻāpana pono ʻole e uhi ana i ka ʻili o ka foil keleawe e hana i ke ʻano kaapuni i makemake ʻia. Penei nā ʻanuʻu hoʻohana kikoʻī: E hoʻolālā i ke ʻano kaapuni i makemake ʻia a hoʻoili i ka ʻili keleawe keleawe. E hoʻopaʻa i ka PCB i loko o ka Etchant, e wehe wale i ka pahu keleawe pale ʻole, e waiho ana i ke ʻano kaapuni i makemake ʻia. E hoʻopaʻa i ka manawa etching e hōʻoia i ka wehe ʻia ʻana o ka foil keleawe i makemake ʻia. Ma kēia ala, hiki iā Etchant ke kōkua i ka hana ʻana i nā ʻano kaapuni i koi ʻia, kahi hana koʻikoʻi i ke kaʻina hana PCB.
