Chojambula chamkuwa cha CNZHJ chili ndi magetsi abwino kwambiri, kuyeretsedwa kwakukulu, kulondola bwino, kutsika kwa okosijeni, kukana mankhwala abwino, komanso kutsekemera kosavuta. Panthawi imodzimodziyo, kuti akwaniritse zosowa za makasitomala osiyanasiyana, CNZHJ ikhoza kudula zojambulazo zamkuwa kukhala mapepala, zomwe zingapulumutse makasitomala ndalama zambiri zogwirira ntchito.
Thechithunzi chowonekeraza zojambulazo zamkuwa ndi chithunzi chofananira cha microscope cha electron ndi motere:
Makulidwe ndi kulemera kwa zojambulazo zamkuwa(Kuchokera ku IPC-4562A)
Makulidwe amkuwa a bolodi yovala zamkuwa ya PCB nthawi zambiri amawonetsedwa mu ma ounces (oz), 1oz = 28.3g, monga 1/2oz, 3/4oz, 1oz, 2oz. Mwachitsanzo, kulemera kwa dera la 1oz/ft² ndikofanana ndi 305 g/㎡ mu mayunitsi a metric. , osinthidwa ndi kachulukidwe ka mkuwa (8.93 g/cm²), wofanana ndi makulidwe a 34.3um.
Tanthauzo la zojambula zamkuwa "1/1": chojambula chamkuwa chokhala ndi malo a 1 square foot ndi kulemera kwa 1 ounce; kufalitsa 1 ounce yamkuwa mofanana pa mbale yokhala ndi 1 lalikulu phazi.
Makulidwe ndi kulemera kwa zojambulazo zamkuwa
☞ED, Electrodeposited copper foil (ED copper foil), amatanthauza zojambula zamkuwa zopangidwa ndi electrodeposition. Njira yopangira ndi njira ya electrolysis. Electrolysis zida zambiri amagwiritsa padziko wodzigudubuza zopangidwa titaniyamu zakuthupi monga wodzigudubuza cathode, apamwamba sungunuka lead ofotokoza aloyi kapena insoluble titaniyamu ofotokoza dzimbiri zosagwira ❖ kuyanika monga anode, ndi asidi sulfuric ndi anawonjezera pakati cathode ndi anode. Electrolyte yamkuwa, yomwe imagwira ntchito mwachindunji, imakhala ndi ayoni amkuwa achitsulo omwe amalowetsedwa pa chodzigudubuza cha cathode kuti apange chojambula choyambirira cha electrolytic. Pamene chodzigudubuza cha cathode chikupitirirabe, chojambula choyambirira chomwe chimapangidwa chimapangidwa nthawi zonse ndikuchipukuta pa chogudubuza. Kenako amatsukidwa, kuumitsa, ndi kuikidwa mu mpukutu wa zojambulazo zaiwisi. Kuyera kwa zojambulazo zamkuwa ndi 99.8%.
☞RA, zojambula zamkuwa zopindidwa, zimachotsedwa mumkuwa kuti apange chithuza chamkuwa, chomwe chimasungunuka, kukonzedwa, kutsukidwa ndi electrolytically, ndikupanga ma ingots amkuwa pafupifupi 2mm wandiweyani. Ingot yamkuwa imagwiritsidwa ntchito ngati maziko, omwe amawotchedwa, amawotcha, ndikuwotcha ndi kukulungidwa (kutalika) pa kutentha pamwamba pa 800 ° C nthawi zambiri. Chiyero 99.9%.
☞HTE, chojambula chamkuwa chotalikirapo kutentha kwambiri, ndi chojambula chamkuwa chomwe chimatalika kwambiri pakutentha kwambiri (180°C). Pakati pawo, elongation wa zojambulazo mkuwa ndi makulidwe a 35μm ndi 70μm pa kutentha (180 ℃) ayenera kukhalabe pa oposa 30% ya elongation firiji. Amatchedwanso HD copper zojambulazo (high ductility copper foil).
☞DST, chojambula chamkuwa cha mbali ziwiri, chimakwiyitsa mbali zonse zosalala komanso zolimba. Cholinga chachikulu chapano ndikuchepetsa ndalama. Roughening yosalala pamwamba angapulumutse mkuwa pamwamba mankhwala ndi browning masitepe pamaso lamination. Itha kugwiritsidwa ntchito ngati wosanjikiza wamkati wa zojambulazo zamkuwa za matabwa amitundu yambiri, ndipo safunikira kukhala wofiirira (wodetsedwa) musanapangitse matabwa amitundu yambiri. Choyipa chake ndikuti pamwamba pa mkuwa sayenera kukanda, ndipo ndizovuta kuchotsa ngati pali kuipitsidwa. Pakalipano, kugwiritsa ntchito mapepala a mkuwa opangidwa ndi mbali ziwiri kumachepa pang'onopang'ono.
☞UTF, zojambulazo zowonda kwambiri zamkuwa, zimatanthawuza zojambulazo zamkuwa zokhala ndi makulidwe osakwana 12μm. Zodziwika kwambiri ndi zojambula zamkuwa zomwe zili pansi pa 9μm, zomwe zimagwiritsidwa ntchito pama board osindikizidwa kuti apange mabwalo abwino. Chifukwa chojambula chamkuwa chochepa kwambiri chimakhala chovuta kuchigwira, nthawi zambiri chimathandizidwa ndi chonyamulira. Mitundu ya zonyamulira zimaphatikizapo zojambulazo zamkuwa, zojambulazo za aluminiyamu, filimu yachilengedwe, ndi zina.
