Umuringa wa CNZHJ wumuringa ufite amashanyarazi meza cyane, ubuziranenge bwinshi, neza neza, okiside nkeya, imiti irwanya imiti, kandi byoroshye. Muri icyo gihe, kugirango uhuze ibyifuzo byabakiriya batandukanye, CNZHJ irashobora kugabanya ifu yumuringa mumpapuro, ishobora kuzigama abakiriya amafaranga menshi yo gutunganya.
UwitekaIshushoya feza y'umuringa hamwe na microscope ya elegitoronike ihuye niyi ikurikira:
Ubunini n'uburemere bw'umuringa(Byakuwe muri IPC-4562A)
Umubyimba wumuringa wibibaho byambaye umuringa wa PCB mubisanzwe bigaragarira muri ounces yubwami (oz), 1oz = 28.3g, nka 1 / 2oz, 3 / 4oz, 1oz, 2oz. Kurugero, ubuso bwa 1oz / ft² bingana na 305 g / ㎡ mubice bya metero. , yahinduwe n'ubucucike bw'umuringa (8,93 g / cm²), bihwanye n'ubunini bwa 34.3um.
Igisobanuro cyumuringa wumuringa "1/1": ifu yumuringa ifite ubuso bwa metero kare 1 nuburemere bwa 1; gukwirakwiza isima 1 y'umuringa ku isahani ifite ubuso bwa metero kare 1.
Ubunini n'uburemere bw'umuringa
☞ED, Electrodeposited foil foil (ED y'umuringa wa ED), bivuga ifu y'umuringa ikozwe na electrodeposition. Inzira yo gukora ni inzira ya electrolysis. Ibikoresho bya Electrolysis muri rusange bifashisha uruziga rusanzwe rukozwe mu bikoresho bya titanium nka cathode roller, ubuziranenge bwo mu rwego rwo hejuru rushingiye ku mavuta cyangwa ibishishwa bya titanium biterwa na ruswa irwanya ruswa nka anode, na aside sulfurike yongerwaho hagati ya cathode na anode. Umuringa wa electrolyte, ukurikije ibikorwa byumuyaga utaziguye, ufite ioni yumuringa wumuringa wamamajwe kumurongo wa cathode kugirango ube umwimerere wa electrolytike. Mugihe uruzitiro rwa cathode rukomeje kuzunguruka, umwirondoro wumwimerere wakozwe uhora wamamazwa kandi ugashishwa kuri roller. Noneho irakaraba, ikuma, igakomeretsa mumuzingo wa fayili mbisi. Umuringa wuzuye umuringa ni 99.8%.
☞RA, Rolled annealed foil foil, ikurwa mu bucukuzi bw'umuringa kugira ngo ikore umuringa wa blisteri, ushongeshejwe, utunganyirizwe, usukuye amashanyarazi, kandi ukorwamo ingero z'umuringa zifite uburebure bwa 2mm. Ingoti y'umuringa ikoreshwa nk'ibikoresho fatizo, bigatoranywa, bigabanuka, kandi bishyushye kandi bizunguruka (mu cyerekezo kirekire) ku bushyuhe buri hejuru ya 800 ° C inshuro nyinshi. Ubuziranenge 99.9%.
☞HTE, ubushyuhe bwo hejuru burebure bwa electrodepositike yumuringa wumuringa, ni umuringa wumuringa ukomeza kuramba cyane mubushyuhe bwinshi (180 ° C). Muri byo, kurambura ifiriti y'umuringa ifite uburebure bwa 35 mm na 70μm ku bushyuhe bwo hejuru (180 ℃) bigomba kugumaho hejuru ya 30% yo kuramba ku bushyuhe bw'icyumba. Yitwa kandi umuringa wa HD wumuringa (ductility high foil foil).
☞DST, impande ebyiri zivura umuringa foil, ikomye byombi kandi byoroshye. Intego nyamukuru iriho nukugabanya ibiciro. Gukomeretsa hejuru birashobora gukiza umuringa wo kuvura no gutera intambwe mbere yo kumurika. Irashobora gukoreshwa nkigice cyimbere cyumuringa wumuringa kubibaho byinshi, kandi ntigomba gukenera (kwirabura) mbere yo kumanika imbaho nyinshi. Ikibi ni uko ubuso bw'umuringa butagomba gutoborwa, kandi biragoye kuwukuraho niba hari umwanda. Kugeza ubu, ikoreshwa ryimpande ebyiri zivuwe zumuringa ziragenda zigabanuka.
☞UTF, ultra thin bron foil foil, yerekeza kumuringa wumuringa ufite uburebure buri munsi ya 12 mm. Ibikunze kugaragara cyane ni ifiriti y'umuringa iri munsi ya 9μm, ikoreshwa ku mbaho zicapye zicapye kugirango zikore imiyoboro myiza. Kuberako ifu yumuringa yoroheje cyane kuyifata biragoye kuyifata, mubisanzwe ishyigikirwa nuwitwaye. Ubwoko bw'abatwara harimo ifu y'umuringa, aluminiyumu, firime ngenga, n'ibindi.
