Nekukwezva kwepamusoro mune zvakasiyana-siyana zvezvigadzirwa zvemaindasitiri, mhangura inoonekwa sechinhu chakasiyana-siyana.
Mapepa emhangura anogadzirwa nemaitiro chaiwo ekugadzira mukati meiyo foil chigayo chinosanganisira zvese zvinopisa uye kutonhora kukunguruka.
Pamwe chete nealuminium, mhangura inoshandiswa zvakanyanya muzvigadzirwa zvemaindasitiri sechinhu chakasiyana-siyana pakati pezvinhu zvisiri-ferrous simbi. Kunyanya mumakore achangopfuura, kudiwa kwemhangura foil kwave kukwira kune zvigadzirwa zvemagetsi zvinosanganisira mbozhanhare, makamera edhijitari, uye zvigadzirwa zveIT.
Kugadzirwa kwefoil
Mapepa emhangura matete anogadzirwa ne electrodeposition kana rolling. For electrodeposition high giredhi mhangura inofanirwa kunyungudutswa muasidhi kuti ibudise copper electrolyte. Mushonga we electrolyte uyu unopombwa mumadhiramu akanyudzwa zvishoma, anotenderera anochajwa magetsi. Pamadhiramu aya firimu rakatetepa remhangura inonzi electrodeposited. Iyi nzira inozivikanwawo sekuti plating.
Mune electrodeposited copper yekugadzira maitiro, iyo foil yemhangura inoiswa pane titanium inotenderera dhiramu kubva mumhinduro yemhangura kwainobatanidzwa kune DC voltage sosi. Iyo cathode inonamirwa kune dhiramu uye anode inonyudzwa mumhangura electrolyte mhinduro. Kana munda wemagetsi ukaiswa, mhangura inoiswa padhiramu sezvainotenderera ichimhanya zvishoma. Nzvimbo yemhangura kudivi redhiramu inotsvedzerera asi rimwe divi rine rough. Iyo inononoka iyo ngoma inomhanya, iyo mhangura inowedzera uye zvakasiyana. Iyo mhangura inokwezvwa uye inounganidzwa pane cathode pamusoro petitanium dhiramu. Iyo matte uye chigubhu chikamu chemhangura foil inopfuura nemumatanho akasiyana ekurapa kuitira kuti mhangura ive yakakodzera kugadzirwa kwePCB. Iwo marapirwo anowedzera kunamatira pakati pemhangura uye dielectric interlayer panguva yemhangura clad lamination process. Imwe mukana wekurapa ndeyekuita se anti-tarnish vamiririri nekudzikamisa oxidation yemhangura.
Mufananidzo 1:Electrodeposited Copper Manufacturing ProcessFigure 2 inoratidza maitiro ekugadzira ezvigadzirwa zvemhangura yakakungurutswa. Rolling midziyo yakakamurwa kuita mhando nhatu; zvinoti, zvigayo zvinopisa, zvigayo zvinotonhorera, uye zvigayo zvefoiri.
Makoiri emapuranga akatetepa anogadzirwa uye anozotevera kemikari uye mechanical kurapwa kusvikira aumbwa kuita chimiro chavo chekupedzisira. Maonero ehurongwa hwekukunguruka kwemafoiri emhangura anopiwa muMufananidzo 2. Chivharo chemhangura yakakandwa (yakaenzana kuyerwa: 5mx1mx130mm) inopisa kusvika 750°C. Zvadaro, inopisa yakakungurutswa ichidzoserwa mumatanho akati wandei kusvika pa1/10 yeukobvu hwayo hwepakutanga. Kusati kwatonhora kwekutanga kukungurutsa zvikero zvinobva mukupisa zvinotorwa nekugaya. Mukutonhora kwekukunguruka ukobvu hunoderedzwa kusvika 4 mm uye mapepa anoumbwa kuita makoiri. Iyo nzira inodzorwa nenzira yekuti zvinhu zvinongotora nguva yakareba uye hazvishandure hupamhi hwayo. Sezvo mapepa asingakwanise kuumbwa zvakare mune ino mamiriro (zvinhu zvakashanda zvakaomarara zvakanyanya) vanoenda kunorapwa kupisa uye vanopisa kusvika 550 ° C.
