ʻO nā papa kaapuni paʻi maʻalahi kahi ʻano papa kaapuni i hana ʻia no nā kumu he nui. ʻO kāna mau pōmaikaʻi ma luna o nā papa kaapuni kuʻuna, ʻo ia ka hoʻemi ʻana i nā hewa hui, ʻoi aku ka paʻakikī i nā kaiapuni paʻakikī, a me ka hiki ke lawelawe i nā hoʻonohonoho uila paʻakikī. Hana ʻia kēia mau papa kaapuni me ka hoʻohana ʻana i ka electrolytic copper foil, kahi mea i hōʻike wikiwiki ʻia ʻo ia kekahi o nā mea koʻikoʻi i ka ʻoihana uila a me nā ʻoihana kamaʻilio.

Pehea i hana ʻia ai nā Kaapuni Flex

Hoʻohana ʻia ʻo Flex Circuits i ka uila no nā kumu like ʻole. E like me ka mea i ʻōlelo ʻia ma mua, hoʻemi ia i nā hewa o ka hui, ʻoi aku ka paʻa o ke kaiapuni, a hiki ke mālama i ka uila paʻakikī. Eia nō naʻe, hiki iā ia ke hoʻemi i nā kumukūʻai hana, hoʻemi i ke kaumaha a me ka pono o ka lewa, a hoʻemi i nā wahi interconnection e hoʻonui i ka paʻa. No kēia mau kumu āpau, ʻo nā ʻāpana uila kekahi o nā ʻāpana uila i makemake nui ʻia i ka ʻoihana.

A kaapuni paʻi maʻalahihe ʻekolu mau mea nui: Conductors, Adhesives, and Insulators. Ma muli o ke ʻano o nā kaʻa kaʻa, ua hoʻonohonoho ʻia kēia mau mea ʻekolu no ka holo ʻana o kēia manawa ma ke ala i makemake ʻia e ka mea kūʻai aku, a no laila e launa pū me nā mea uila ʻē aʻe. ʻO ka mea maʻamau no ka hoʻopili ʻana o ke kaapuni flex he epoxy, acrylic, PSA, a i ʻole kekahi manawa, ʻoiai nā insulators i hoʻohana mau ʻia me ka polyester a me ka polyamide. I kēia manawa, makemake nui mākou i nā conductors i hoʻohana ʻia i kēia mau kaapuni.

ʻOiai hiki ke hoʻohana ʻia nā mea ʻē aʻe e like me ke kālā, carbon, a me ka aluminika, ʻo ka mea maʻamau i hoʻohana ʻia no nā conductors he keleawe. Manaʻo ʻia ʻo Copper foil he mea koʻikoʻi no ka hana ʻana i nā kaʻa flex, a ua hana ʻia ma nā ala ʻelua: rolling annealing a i ʻole electrolysis.

Pehea i hana ʻia ai nā ʻāpana keleawe

ʻO ka pepa keleawe annealed i ʻōwili ʻiahana ʻia ma o ka ʻōwili ʻia ʻana o nā ʻāpana keleawe wela, hoʻoheheʻe ʻia i lalo a hana i kahi ʻili keleawe maʻemaʻe. Hoʻopili ʻia nā ʻāpana keleawe i nā wela kiʻekiʻe a me nā kaomi ma o kēia ʻano hana, e hana ana i kahi ʻili maʻemaʻe a hoʻomaikaʻi i ka ductility, ka hiki, a me ka conductivity.

I kēia manawa,electrolytic copper foil hanaia ma ka hoohana ana i ka hana electrolysis. Hana ʻia kahi hopena keleawe me ka sulfuric acid (me nā mea hoʻohui ʻē aʻe e pili ana i nā kikoʻī o ka mea hana). Holo ʻia kahi pūnaʻi electrolytic ma o ka hopena, a laila e hoʻoheheʻe ʻia nā ion keleawe a pae ma ka ʻili cathode. Hiki ke hoʻohui pū ʻia nā mea hoʻohui i ka hopena e hiki ke hoʻololi i kona mau waiwai kūloko a me kona ʻano.

Ke hoʻomau nei kēia kaʻina hana electroplating a hiki i ka wehe ʻana o ka pahu cathode mai ka hopena. Na ka pahu ho'i e ho'omalu i ka mānoanoa o ka pahu keleawe, no ka mea, 'o ka pahu ka'ili'ili wikiwiki ho'i e huki hou i ka ua, e mānoanoa ai ka pepa.

ʻO ke ʻano o ke ʻano, e mālama mau ʻia nā pahu keleawe a pau i hana ʻia mai kēia mau ʻano ʻelua me ka mālama paʻa ʻana, ka mālama ʻana i ka wela, a me ka mālama kūpaʻa (anti-oxidation) ma hope. ʻO kēia mau lāʻau lapaʻau e hiki ai i nā pahu keleawe ke hoʻopaʻa maikaʻi i ka mea hoʻopili, e ʻoi aku ka paʻa i ka wela i ka hana ʻana i ke kaapuni paʻi maʻalahi maoli, a pale i ka hoʻoheheʻe ʻana o ka foil keleawe.

Hoʻopili ʻia ʻo Annealed vs Electrolytic

No ka mea ʻokoʻa ke kaʻina hana no ka hoʻokumu ʻana i ka foil keleawe o rolled annealed a me ka electrolytic copper foil, loaʻa iā lākou nā pono like ʻole a me nā hemahema.

ʻO ka ʻokoʻa nui ma waena o nā ʻāpana keleawe ʻelua ma ke ʻano o ko lākou ʻano. E loaʻa i kahi ʻāpana keleawe i hoʻopaʻa ʻia i ʻōwili ʻia i ke ʻano ākea i ka mahana maʻamau, a laila e lilo i loko o kahi ʻano aniani lamellar i ka wā e kau ʻia ai ke kaomi kiʻekiʻe a me ka mahana. I kēia manawa, hoʻopaʻa ka electrolytic copper foil i kona ʻano kolamu ma nā mahana maʻamau a me nā kaomi kiʻekiʻe a me nā mahana.

Hoʻokumu kēia i nā ʻokoʻa i ka conductivity, ductility, bendability, a me ke kumu kūʻai o nā ʻano ʻelua o ka foil keleawe. No ka mea, ʻoi aku ka maʻalahi o nā pahu keleawe annealed i ʻōwili ʻia, ʻoi aku ka conductive a ʻoi aku ka kūpono no nā uea liʻiliʻi. ʻOi aku ka ductile a ʻoi aku ka maʻalahi ma mua o ka electrolytic copper foil.

Eia nō naʻe, ʻo ka maʻalahi o ke ʻano electrolysis e hōʻoia i ka electrolytic copper foil he haʻahaʻa haʻahaʻa ma mua o nā foil keleawe annealed rolled. E noʻonoʻo naʻe, ʻo ia paha kahi koho suboptimal no nā laina liʻiliʻi, a ʻoi aku ka maikaʻi o ke kūlou ʻana ma mua o nā foil keleawe annealed.

I ka hopena, he koho haʻahaʻa haʻahaʻa maikaʻi nā pahu keleawe electrolytic ma ke ʻano he alakaʻi i kahi kaapuni paʻi maʻalahi. Ma muli o ke koʻikoʻi o ka flex circuit i ka uila a me nā ʻoihana ʻē aʻe, ʻo ia hoʻi, hana i nā foil keleawe electrolytic i mea koʻikoʻi.
