Mhangura ndiyo imwe yesimbi dzinoshandiswa zvakasiyana-siyana munyika. Zvinhu zvayo zvakasiyana-siyana zvinoita kuti zvive zvakakodzera kune zvakasiyana-siyana zvekushandisa, kusanganisira conductivity yemagetsi. Mhangura inoshandiswa zvakanyanya mumaindasitiri emagetsi nemagetsi, uye foils yemhangura zvinhu zvakakosha pakugadzira akadhindwa edunhu mabhodhi (PCBs). Pakati pemhando dzakasiyana dzemhangura dzemhangura dzinoshandiswa mukugadzirwa kwePCBs, ED copper foil ndiyo inonyanya kushandiswa.
ED copper foil inogadzirwa ne electro-deposition (ED), inova maitiro anosanganisira kuiswa kwemaatomu emhangura panzvimbo yesimbi kuburikidza nemagetsi. Iyo inokonzeresa foil yemhangura yakachena kwazvo, yakafanana, uye ine yakanakisa michina uye yemagetsi zvivakwa.
Imwe yemabhenefiti makuru eED copper foil ndiko kufanana kwayo. Iyo electro-deposition process inovimbisa kuti ukobvu hwemhangura foil hunoenderana munzvimbo yayo yese, iyo yakakosha mukugadzira PCB. Ukobvu hwefoiri yemhangura hunowanzo kutsanangurwa mumamicrons, uye hunogona kubva kune mashoma mamicrons kusvika kumakumi akati wandei emakroni, zvichienderana nekushandiswa. Ukobvu hwefoiri yemhangura hunotaridza mafambisirwo ayo emagetsi, uye foil yakakora kazhinji ine yakakwirira conductivity.
Pamusoro pekufanana kwayo, ED yemhangura foil ine yakanakisa michina zvivakwa. Inochinjika zvakanyanya uye inogona kukotama zviri nyore, kuumbwa, uye kuumbwa kuti ikwane makona ePCB. Uku kuchinjika kunoita kuti ive chinhu chakanakira kugadzira maPCB ane akaomarara geometries uye akaomarara dhizaini. Uyezve, iyo yakakwira ductility yemhangura foil inobvumira kuti igone kumira yakadzokororwa kukotama uye kuchinjika pasina kuputika kana kutyora.
Imwe pfuma yakakosha yeED copper foil ndeyemagetsi conductivity. Mhangura ndiyo imwe yesimbi inofambisa, uye ED copper foil ine conductivity inopfuura 5 × 10 ^ 7 S/m. Iyi yepamusoro yepamusoro ye conductivity inokosha mukugadzirwa kwePCBs, iyo inogonesa kutumirwa kwemagetsi emagetsi pakati pezvikamu. Uyezve, kushomeka kwemagetsi kwefoiri yemhangura kunoderedza kurasikirwa kwesimba rechiratidzo, iyo yakakosha mukumhanya-mhanya uye yakakwirira-frequency application.
ED copper foil zvakare inopokana zvakanyanya neoxidation uye corrosion. Mhangura inopindirana neokisijeni mumhepo kuti iite mutsetse wakatetepa wecopper oxide pamusoro payo, iyo inogona kukanganisa mafambisirwo ayo emagetsi. Nekudaro, ED yemhangura foil inowanzo kuputirwa nedhizaini yezvinhu zvinodzivirira, senge tini kana nickel, kudzivirira oxidation uye kunatsiridza kwayo solderability.
Mukupedzisa, ED copper foil chinhu chakasiyana uye chakakosha mukugadzirwa kwePCB. Kufanana kwayo, kuchinjika, yakakwirira magetsi conductivity, uye kuramba kune oxidation uye corrosion inoita kuti ive chinhu chakanakira kugadzira maPCB ane akaomarara geometries uye yakakwirira-kuita zvinodiwa. Nekukura kuri kudiwa kweakakwira-kumhanya uye yakakwira-frequency zvemagetsi, kukosha kweED copper foil kunongoiswa kuti iwedzere mumakore anotevera.
