Nīnau pinepine ʻia mākou e pili ana i ka maʻalahi. ʻOiaʻiʻo, no ke aha ʻoe e koi ai i kahi papa "flex"?
"E pohā paha ka papa flex inā hoʻohana ʻia ke keleawe ED ma luna?''
Ma loko o kēia ʻatikala makemake mākou e noiʻi i ʻelua mau mea like ʻole (ED-Electrodeposited a me RA-rolled-annealed) a nānā i ko lākou hopena i ka lōʻihi o ke kaapuni. ʻOiai ua hoʻomaopopo maikaʻi ʻia e ka ʻoihana flex, ʻaʻole mākou e loaʻa i kēlā memo koʻikoʻi i ka mea hoʻolālā papa.
E noʻonoʻo kākou i kēia mau ʻano pepa ʻelua. Eia ka mākaʻikaʻi ʻāpana o RA Copper a me ED Copper:
ʻO ka maʻalahi o ke keleawe mai nā kumu he nui. ʻOiaʻiʻo, ʻoi aku ka lahilahi o ke keleawe, ʻoi aku ka maʻalahi o ka papa. Ma waho aʻe o ka mānoanoa (a i ʻole ka lahilahi), pili pū ka palaoa keleawe i ka loli. ʻElua mau ʻano keleawe maʻamau i hoʻohana ʻia ma ka PCB a me nā mākeke kaapuni flex: ED a me RA e like me ka mea i ʻōlelo ʻia.
Roll Anneal Copper Foil (RA keleawe)
Ua hoʻohana nui ʻia ʻo Rolled Annealed (RA) Copper i ka hana ʻana o nā kaʻa kaʻa a me ka ʻoihana PCB paʻa paʻa no nā makahiki.
ʻO ke ʻano o ka palaoa a me ka ʻili maʻemaʻe he mea kūpono ia no ka hoʻohana ʻana i ka circuitry dynamic. Aia kekahi wahi hoihoi me nā ʻano keleawe ʻōwili ʻia i nā hōʻailona kiʻekiʻe a me nā noi.
Ua hōʻike ʻia e hiki i ka ʻinoʻino o ka ʻili keleawe ke hoʻopilikia i ka nalowale o ka hoʻokomo ʻana i nā alapine kiʻekiʻe a ʻoi aku ka maikaʻi o ka ʻili keleawe maʻemaʻe.
Electrolysis Deposition Copper Foil (ED copper)
Me ke keleawe ED, nui ka ʻokoʻa o nā foil e pili ana i ka ʻeleʻele o ka ʻili, ka mālama ʻana, ke ʻano o ka palaoa, a me nā mea ʻē aʻe. ʻO ke keleawe ED maʻamau he ʻano kiʻekiʻe kiʻekiʻe a i ʻole ka ʻili ʻeleʻele i hoʻohālikelike ʻia me Rolled Annealed (RA) Copper. ʻAʻole lawa ka maʻalahi o ka ED copper a ʻaʻole ia e hāpai i ka hōʻailona hōʻailona maikaʻi.
ʻAʻole kūpono ke keleawe EA no nā laina liʻiliʻi a me ke kūpaʻa kūlou maikaʻi ʻole i hoʻohana ʻia ke keleawe RA no ka PCB maʻalahi.
Eia naʻe, ʻaʻohe kumu e makaʻu ai i ka keleawe ED i nā noi ikaika.
Eia naʻe, ʻaʻohe kumu e makaʻu ai i ka keleawe ED i nā noi ikaika. ʻO ka mea ʻē aʻe, ʻo ia ke koho de facto i nā noi mea kūʻai aku lahilahi a māmā e koi ana i nā helu pōʻai kiʻekiʻe. ʻO ka hopohopo wale nō ka mālama pono ʻana i kahi e hoʻohana ai mākou i ka plating "additive" no ke kaʻina PTH. ʻO RA foil wale nō ke koho i loaʻa no nā kaupaona keleawe ʻoi aku ke kaumaha (ma luna o 1 oz.) kahi e koi ʻia ai nā noi ʻoi aku ke kaumaha a me ka hoʻololi ikaika.
No ka hoʻomaopopoʻana i nā mea maikaʻi a me nā pōʻino o kēia mau meaʻelua, he mea nui e hoʻomaopopo i nā pōmaikaʻi ma nā kumukūʻai a me ka hanaʻana o kēia mauʻano keleawe keleaweʻelua a, e like me ka mea nui, nā mea i loaʻa i ke kālepa. Pono ka mea hoʻolālā e noʻonoʻo ʻaʻole wale i ka mea e hana ai, akā inā hiki ke kūʻai ʻia ma ke kumukūʻai ʻaʻole e hoʻokuke i ka huahana hope i waho o ka mākeke pricewise.
