Loaʻa i ka CNZHJ's copper foil ka hana uila maikaʻi loa, ka maʻemaʻe kiʻekiʻe, ka pololei maikaʻi, ka liʻiliʻi o ka oxidation, ke kūpaʻa kemika maikaʻi, a me ka maʻalahi o ka etching. I ka manawa like, i mea e hoʻokō ai i nā pono hana o nā mea kūʻai like ʻole, hiki i ka CNZHJ ke ʻoki i ka foil keleawe i loko o nā pepa, hiki ke hoʻopakele i nā mea kūʻai aku i ka nui o nā koina hana.
ʻO kakiʻi helehelenao ka pepa keleawe a me ke ki'i scan microscope electron like penei:
ʻO ka mānoanoa a me ke kaumaha o ke keleawe keleawe(Wehe ʻia mai IPC-4562A)
Hōʻike pinepine ʻia ka mānoanoa keleawe o ka PCB i hoʻopaʻa ʻia i ka papa keleawe i nā auneke imperial (oz), 1oz=28.3g, e like me 1/2oz, 3/4oz, 1oz, 2oz. No ka laʻana, ua like ka nuipa o 1oz/ft² me 305 g/㎡ i nā ʻāpana metric. , hoʻololi ʻia e ka nui keleawe (8.93 g/cm²), e like me ka mānoanoa o 34.3um.
ʻO ka wehewehe ʻana o ka pahu keleawe "1/1": kahi pahu keleawe me kahi ʻāpana o 1 kapuaʻi square a me ke kaumaha o 1 auneke; e hohola like i 1 auneke keleawe ma ka papa me ka ili o 1 kapuai kuea.
ʻO ka mānoanoa a me ke kaumaha o ke keleawe keleawe
☞ED, Electrodeposited copper foil (ED copper foil), pili i ke keleawe foil i hanaia e ka electrodeposition. ʻO ke kaʻina hana he hana electrolysis. Hoʻohana maʻamau nā lako Electrolysis i ka ʻili ʻili i hana ʻia me ka mea titanium e like me ka cathode roller, kiʻekiʻe kiʻekiʻe soluble lead-based alloy a i ʻole ka titanium-based corrosion-resistant coating e like me ka anode, a hoʻohui ʻia ka sulfuric acid ma waena o ka cathode a me ka anode. ʻO ke keleawe electrolyte, ma lalo o ka hana o ke au pololei, loaʻa nā ion keleawe metala i hoʻopili ʻia ma ka roller cathode e hana i ka foil kumu electrolytic. Ke hoʻomau nei ka ʻōwili ʻana o ka cathode roller, hoʻopili mau ʻia ka pahu kumu i hana ʻia a ʻili ʻia ma luna o ka huila. A laila holoi ʻia, hoʻomaloʻo, a ʻoki ʻia i loko o kahi ʻōwili pepa maka. ʻO ka hoʻomaʻemaʻe keleawe keleawe he 99.8%.
☞RA, ʻO ka pepa keleawe i hoʻopaʻa ʻia i ʻōwili ʻia, ua unuhi ʻia mai loko mai o ka ʻoa keleawe e hana i ke keleawe blister, ka mea i hoʻoheʻe ʻia, hana ʻia, hoʻomaʻemaʻe electrolytically, a hana ʻia i loko o nā ʻāpana keleawe ma kahi o 2mm mānoanoa. Hoʻohana ʻia ka ingot keleawe ma ke ʻano he kumu kumu, ʻo ia ka pickled, degreased, a me ka wela a ʻōwili ʻia (ma ke ala lōʻihi) i nā mahana ma luna o 800 ° C no nā manawa he nui. Maʻemaʻe 99.9%.
☞HTE, kiʻekiʻe wela elongation electrodeposited copper foil, he keleawe foil e malama maikai elongation ma kiʻekiʻe wela (180°C). I waena o lākou, pono e mālama ʻia ka elongation o ke keleawe keleawe me ka mānoanoa o 35μm a me 70μm i ke kiʻekiʻe wela (180 ℃) ma mua o 30% o ka elongation ma ke ana wela. Kāhea ʻia hoʻi ʻo HD copper foil (high ductility copper foil).
☞DST, ʻāpana keleawe ʻaoʻao ʻelua i hoʻopaʻa ʻia, hoʻopōʻino i nā ʻili paheʻe a me ka ʻala. ʻO ke kumu nui o kēia manawa ʻo ka hoʻemi ʻana i nā kumukūʻai. Hiki ke ho'ōla i ka mālama ʻana i ka ʻili keleawe a me ka browning ma mua o ka lamination. Hiki ke hoʻohana ʻia e like me ka ʻāpana o loko o ka pahu keleawe no nā papa multi-layer, a ʻaʻole pono e ʻulaʻula (ʻeleʻele) ma mua o ka laminating ʻana i nā papa multi-layer. ʻO ka pōʻino, ʻaʻole pono e ʻoki ʻia ka ʻili keleawe, a paʻakikī ke wehe inā loaʻa ka ʻino. I kēia manawa, ke emi mālie nei ka hoʻohana ʻana i nā ʻāpana keleawe ʻelua ʻaoʻao.
☞UTF, ʻeleʻele keleawe lahilahi, e pili ana i ka pepa keleawe me ka mānoanoa ma lalo o 12μm. ʻO nā mea maʻamau he mau pahu keleawe ma lalo o 9μm, i hoʻohana ʻia ma nā papa kaapuni paʻi no ka hana ʻana i nā kaapuni maikaʻi. Ma muli o ka paʻakikī o ka hoʻohana ʻana i ka pepa keleawe lahilahi, kākoʻo mau ʻia e ka mea lawe. ʻO nā ʻano o nā mea lawe e komo pū me ka foil keleawe, ka alumini alumini, ke kiʻi ʻoniʻoni, etc.
