Te matotoru me te taumaha o te pepa parahi(I tangohia mai i IPC-4562A)
Ko te matotoru o te parahi o te papapa parahi-kakahu PCB te nuinga o te wa e whakaatuhia ana i roto i nga hekere emepaea (oz), 1oz=28.3g, penei i te 1/2oz, 3/4oz, 1oz, 2oz. Hei tauira, ko te papatipu horahanga o te 1oz/ft² he rite ki te 305 g/㎡ i roto i nga wae ine. , ka hurihia e te kiato parahi (8.93 g/cm²), he rite ki te matotoru o te 34.3um.
Ko te whakamaramatanga o te pepa parahi "1/1": he pepa parahi me te whanui o te 1 waewae tapawha me te taimaha o te 1 hekere; horahia kia 1 hekere parahi ki runga i te pereti 1 waewae tapawha te whanui.
Te matotoru me te taumaha o te pepa parahi
☞ED, Electrodeposited copper foil (ED copper foil), e tohu ana ki te pepa parahi i hangaia e te electrodeposition. Ko te mahi hanga he tukanga electrolysis. I te nuinga o te waa ka whakamahia e nga taputapu hiko he roera mata he mea hanga mai i nga rawa titanium hei roera cathode, koranu whakarewa-a-wai-a-te-kounga-kounga teitei, he whakakikorua-a-te-titanium-kore ranei hei whakakikorua hei anode, ka taapirihia te waikawa pungatara ki waenga i te cathode me te anode. Ko te konukura electrolyte, i raro i te mahi o te naianei tika, he katote parahi whakarewa kua whakauruhia ki runga i te roera cathode hei hanga i te pepa hiko hiko. I te mea e huri haere tonu ana te roera cathode, ka mau tonu te konumohe taketake i hangaia ka tihorea ki runga i te roera. Katahi ka horoia, ka whakamarokehia, ka werohia ki roto i te pukapuka konumohe mata. Ko 99.8%.
☞RA, Ko te pepa konupuku kua whakatakahia, he mea tango mai i te konukura hei whakaputa i te konukura opupu, ka whakarewahia, ka tukatukahia, ka purea i te hiko, ka mahia ki roto i te konukura konukura e 2mm te matotoru. Ka whakamahia te ingot parahi hei rauemi turanga, he mea î, he whakaheke, he wera me te huri (i te huarahi roa) i nga mahana i runga ake i te 800 ° C mo nga wa maha. Maamaa 99.9%.
☞HTE, te teitei o te pāmahana elongation electrodeposited copper foil, he pepa parahi e mau tonu ana te roanga pai i te pāmahana teitei (180°C). I roto ia ratou, ko te elongation o te konumohe parahi ki te matotoru o 35μm me 70μm i te pāmahana teitei (180 ℃) kia mau tonu i neke atu i te 30% o te elongation i te pāmahana rūma. Ka karangahia ano he pepa parani HD (kopa parapara teitei).
☞DST, konumohe parapara maimoatanga taha-rua, he mea taratara nga papa maeneene me te taratara. Ko te kaupapa matua o naianei he whakaiti i nga utu. Ka taea e te tarai i te mata maeneene te whakaora i te maimoatanga mata parahi me nga hikoi parauri i mua i te lamination. Ka taea te whakamahi hei paparanga o roto o te konumohe parahi mo nga papa paparanga maha, kaore e hiahiatia kia parauri (pango) i mua i te whakakikorua i nga papa paparanga maha. Ko te kino ko te kore e rakurakuhia te mata parahi, he uaua ki te tango mena he poke. I tenei wa, kei te heke haere te tono o te konumohe parahi kua oti te whakangao-rua.
☞UTF, pepa parahi tino angiangi, e pa ana ki te pepa parahi me te matotoru iti iho i te 12μm. Ko nga mea tino noa ko nga pepa parahi kei raro iho i te 9μm, e whakamahia ana i runga i nga papa taiawhio mo te hanga iahiko pai. Na te mea he uaua ki te hapai i te pepa parahi tino kikokore, ka tautokohia e te kaikawe. Ko nga momo kaikawe ko te pepa parahi, te konumohe konumohe, te kiriata pararopi, me era atu.
