Mafoiri emhangura eED akakora kwazvo
Nhanganyaya yeChigadzirwa
Foil yemhangura ine gobvu rakakora kwazvo inogadzirwa neCIVEN METAL haingogone kugadzikiswa chete kana tichitarisa ukobvu hwefoil yemhangura, asiwo ine gobvu diki uye simba rekuparadzanisa rakawanda, uye pamusoro payo pakaoma hapasi nyore kudonha kubva pahupfu. Tinogonawo kupa sevhisi yekucheka zvichienderana nezvinodiwa nevatengi.
Magadzirirwo
CIVEN inogona kupa foil yemhangura yakakora zvakanyanya, isina chimiro chakaderera, ine tembiricha yakakwira, ine ductile yakakora zvakanyanya (VLP-HTE-HF) kubva pa3oz kusvika 12oz (ukobvu hwakaderera 105µm kusvika 420µm), uye saizi yepamusoro yechigadzirwa ifoil yemhangura yepepa 1295mm x 1295mm.
Kushanda
CIVEN inopa foil yemhangura yakakora kwazvo ine hunhu hwakanaka hwekristaro yakanaka, chimiro chakaderera, simba rakawanda uye kureba kwakakwirira. (Ona Tafura 1)
Mashandisirwo
Inoshanda pakugadzira mabhodhi emagetsi ane simba guru uye mabhodhi ane simba guru rekufambisa mota, magetsi, kutaurirana, zvemauto uye zvemuchadenga.
Hunhu
Kuenzanisa nezvigadzirwa zvekunze zvakafanana.
1. Chimiro chezviyo cheVLP brand yedu ine gobvu guru re electrolytic copper foil chakaenzana ne crystal fine spherical; nepo chimiro chezviyo chezvigadzirwa zvakafanana zvekunze kwenyika chakareba uye chakakora.
2. CIVEN copper foil yakakora zvakanyanya ine chimiro chakaderera zvakanyanya, 3oz copper foil gross surface Rz ≤ 3.5µm; nepo zvigadzirwa zvakafanana zvekunze zviri standard profile, 3oz copper foil gross surface Rz > 3.5µm.
Zvakanakira
1. Sezvo chigadzirwa chedu chisina chimiro chakanyanya, chinogadzirisa njodzi inogona kuitika yemutsara mupfupi nekuda kwekuoma kukuru kwefoil yemhangura yakakora uye kupinda nyore kwepepa rePP rakatetepa ne "wolf tooth" kana uchidzvanya panel ine mativi maviri.
2. Nekuti chimiro chezviyo zvezvigadzirwa zvedu chakaenzana nekristaro yakanaka, chinopfupisa nguva yekuchekwa kwemitsara uye chinovandudza dambudziko rekuchekwa kwemativi asina kuenzana kwemitsara.
3. Iine simba rakakura rekubvisa mavanga, isina kutamiswa kweupfu hwemhangura, mashandiro akajeka ekugadzira PCB.

Cherechedza:1. Kukosha kweRz kwepombi yemhangura ndiyo kukosha kwakasimba kwekuyedza, kwete kukosha kwakavimbiswa.
2. Simba rekubvisa mapeel ndiro chiyero chebvunzo yeFR-4 board (mapepa mashanu e7628PP).
3. Nguva yekuvimbisa hunhu hwezvinhu mazuva makumi mapfumbamwe kubva pazuva rekugamuchira.
