1. Chiyambi cha Zojambula Zamkuwa
Copper zojambulazo (mkuwa zojambulazo): mtundu cathode electrolytic zakuthupi, woonda, mosalekeza zitsulo zojambulazo waikamo pa m'munsi wosanjikiza wa bolodi dera, amene amachita ngati kondakitala wa PCB. Imamatira mosavuta pansanjika yotsekereza, imavomereza zosanjikiza zotetezedwa zosindikizidwa, ndikupanga mawonekedwe ozungulira pambuyo pa dzimbiri. Mayeso a galasi la mkuwa (mayeso a galasi lamkuwa): kuyesa kwa dzimbiri, pogwiritsa ntchito filimu yoyika vacuum pa mbale yagalasi.
Chojambula chamkuwa chimapangidwa ndi mkuwa ndi gawo lina la zitsulo zina. Zojambula zamkuwa nthawi zambiri zimakhala ndi zojambulazo 90 ndi zojambulazo 88, ndiye kuti, zomwe zili mkuwa ndi 90% ndi 88%, ndipo kukula kwake ndi 16 * 16cm. Zojambula zamkuwa ndizogwiritsidwa ntchito kwambiri zokongoletsera zokongoletsera. Monga: mahotela, akachisi, ziboliboli za Buddha, zikwangwani zagolide, zojambulajambula za matailosi, ntchito zamanja, ndi zina zambiri.
2. Makhalidwe a mankhwala
Chojambula chamkuwa chimakhala ndi mawonekedwe otsika a okosijeni ndipo amatha kumangirizidwa kumadera osiyanasiyana, monga zitsulo, zida zotsekera, ndi zina zambiri, ndipo zimakhala ndi kutentha kwakukulu. Amagwiritsidwa ntchito makamaka mu electromagnetic shielding ndi antistatic. Chojambula chamkuwa cha conductive chimayikidwa pamwamba pa gawo lapansi ndikuphatikizidwa ndi gawo lapansi lachitsulo, lomwe lili ndi madulidwe abwino kwambiri ndipo limapereka chitetezo chamagetsi. Akhoza kugawidwa mu: kudziona zomatira mkuwa zojambulazo, iwiri-kuchititsa zojambulazo mkuwa, limodzi-kuchititsa zojambulazo mkuwa, etc.
Electronic kalasi mkuwa zojambulazo (kuyera pamwamba 99,7%, makulidwe 5um-105um) ndi chimodzi mwa zinthu zofunika makampani zamagetsi. Kukula mofulumira kwa makampani a zamagetsi, kugwiritsa ntchito zipangizo zamagetsi zamkuwa zamkuwa zikuchulukirachulukira, ndipo mankhwalawa amagwiritsidwa ntchito kwambiri muzowerengetsera zamakampani, zida zolankhulana, zida za QA, mabatire a lithiamu-ion, ma TV wamba, zojambulira mavidiyo, osewera ma CD, makina ojambula zithunzi, mafoni, zoziziritsa kukhosi, zida zamagetsi zamagetsi, masewera amasewera, etc. Misika yoweta ndi yakunja imakhala ndi kufunikira kowonjezereka kwa zojambula zamkuwa zamkuwa, makamaka zida zapamwamba zamagetsi zamagetsi zamkuwa. Mabungwe oyenerera amalosera kuti pofika chaka cha 2015, zomwe dziko la China likufuna kupanga zojambula zamkuwa zamtundu wamagetsi zidzafika matani 300,000, ndipo dziko la China lidzakhala malo akuluakulu padziko lonse lapansi opanga mapepala osindikizira ndi zojambula zamkuwa. Msika wa zojambula zamkuwa zamtundu wamagetsi, makamaka zojambula zapamwamba, ndi zabwino. .
3. kuperekedwa kwapadziko lonse kwa zojambula zamkuwa
Zojambula zamkuwa zamakampani zitha kugawidwa m'magulu awiri: zojambulazo zamkuwa (zojambulazo zamkuwa za RA) ndi zojambulazo zamkuwa (ED copper zojambulazo). Pakati pawo, adagulung'undisa mkuwa zojambulazo ali ductility zabwino ndi makhalidwe ena, amene ntchito oyambirira ndondomeko zofewa bolodi. Chojambula chamkuwa, ndi zojambulazo za electrolytic zili ndi mwayi wotsika mtengo wopangira kuposa zojambulazo zamkuwa. Popeza zojambulazo zopindidwa zamkuwa ndizofunikira kwambiri pama board osinthika, kuwongolera kwa mawonekedwe ndi kusintha kwamitengo ya zojambulazo zopindidwa zamkuwa zimakhudza kwambiri makampani osinthika.
Popeza pali ochepa omwe amapanga zojambulazo zamkuwa, ndipo teknoloji ilinso m'manja mwa opanga ena, makasitomala ali ndi mphamvu zochepa pa mtengo ndi kupereka. Chifukwa chake, popanda kukhudza magwiridwe antchito, zojambula zamkuwa za electrolytic zimagwiritsidwa ntchito m'malo mwakugudubuza zojambulazo za Copper ndi yankho lotheka. Komabe, ngati mawonekedwe a zojambula zamkuwa adzakhudzanso zinthu zomwe zimapangidwira zaka zingapo zikubwerazi, kufunikira kwa zojambulazo zamkuwa kudzawonjezekanso muzinthu zowonda kapena zowonda kwambiri, komanso zopangidwa ndi ma frequency apamwamba chifukwa choganizira matelefoni.
Pali zopinga zazikulu ziwiri pakupanga zojambulazo zopindidwa zamkuwa, zopinga zantchito ndi zopinga zaukadaulo. Chotchinga chothandizira chimatanthawuza kufunikira kwa zipangizo zamkuwa zothandizira kupanga zojambulazo zamkuwa, ndipo ndizofunikira kwambiri kukhala ndi chuma. Kumbali ina, zopinga zaukadaulo zimalepheretsa olowa atsopano ambiri. Kuphatikiza pa ukadaulo wa calendering, chithandizo chapamwamba kapena ukadaulo wa oxidation umagwiritsidwanso ntchito. Mafakitole ambiri padziko lonse lapansi ali ndi matekinoloje ambiri aukadaulo komanso ukadaulo wofunikira Dziwani Momwe, zomwe zimachulukitsa zotchinga kulowa. Ngati olowa atsopano atatha kukolola ndi kupanga, amaletsedwa ndi mtengo wa opanga akuluakulu, ndipo sikophweka kulowa nawo msika. Chifukwa chake, zojambula zamkuwa zapadziko lonse lapansi zikadali zamsika wokhazikika.
3. chitukuko cha zojambulazo zamkuwa
Chojambula chamkuwa mu Chingerezi ndi electrodepositedcopperfoil, yomwe ndi yofunika kwambiri popanga laminate yamkuwa (CCL) ndi bolodi losindikizidwa (PCB). Pachitukuko chofulumira chamakono chamakampani azidziwitso zamagetsi, zojambula zamkuwa za electrolytic zimatchedwa: "neural network" yamagetsi amagetsi amagetsi ndi kufalitsa mphamvu ndi kulumikizana. Kuyambira 2002, kupanga mtengo wa matabwa kusindikizidwa dera China kuposa malo wachitatu mu dziko, ndi lamkuwa atavala laminates, gawo lapansi za PCBs, nawonso wakhala sewerolo lachitatu lalikulu mu dziko. Zotsatira zake, makampani aku China opanga zojambula zamkuwa a electrolytic atukuka kwambiri m'zaka zaposachedwa. Pofuna kumvetsetsa ndi kumvetsetsa zakale ndi zamakono za dziko lapansi komanso chitukuko cha makampani opanga zojambula zamkuwa za electrolytic ku China, ndikuyembekezera zam'tsogolo, akatswiri a China Epoxy Resin Industry Association adawunikiranso chitukuko chake.
Kuchokera ku dipatimenti yopanga ndi chitukuko cha msika wa makampani opanga zojambula zamkuwa za electrolytic, chitukuko chake chikhoza kugawidwa m'zigawo zitatu zazikulu zachitukuko: United States inakhazikitsa bizinesi yoyamba yapadziko lonse lapansi yamkuwa ndi nthawi yomwe makampani opanga zojambula zamkuwa anayamba; Chojambula chamkuwa cha ku Japan Nthawi yomwe mabizinesi amalamulira msika wapadziko lonse lapansi; nthawi yomwe dziko lapansi lili ndi polarized kuti lipikisane pamsika.
