Copper wire tinning inoshandiswa zvakanyanya mukugadzirwa kwewaya, tambo, uye waya dzine enameled.Iyo tin coating inopenya uye silvery chena, iyo inogona kuwedzera weldability uye kushongedzwa kwemhangura pasina kukanganisa magetsi conductivity.Inogona kushandiswa muindasitiri yemagetsi, fenicha, kurongedza chikafu, etc. Anti-oxidation, wedzera kunaka kwemhangura workpieces.Hapana chikonzero chemidziyo ye electroplating, inongoda kunyura, nyore uye yakapusa, uye inogona kuputirwa nesimbi gobvu.[1]

Nhanganyaya
1. Tinned copper waya ine yakanakisa solderability.

2. Sezvo nguva ichichinja, solderability inoramba yakanaka uye inogona kuchengetwa kwenguva yakareba.

3. Nzvimbo yacho yakatsetseka, yakajeka uye yakanyorova.

4. Kushanda kwakasimba uye kwakavimbika, kuve nechokwadi chepamusoro uye goho guru.

Zviratidzo zvemuviri uye zvemakemikari
1. Yakananga giravhiti: 1.04 ~ 1.05

2. PH: 1.0~1.2

3. Kuonekwa: mvura isina ruvara yakajeka

process flow
Kubvisa simbi yemhangura — pickling or polishing — washings kaviri — electroless tin plating — matatu washing — dry in time with cold wind — testing.

Electroless tin plating: Wedzera 8 ~ 10g/kg yetin plating additives kumvura yekuisa mumarata usati washandisa.Tembiricha yekunyudza tini ndeye yakajairika tembiricha ~ 80 ℃, uye nguva yekunyudza tini maminetsi gumi nemashanu.Munguva yekugadzira tin plating, mhinduro yeplating inofanira kumutswa zvinyoronyoro kana kuti workpiece inofanira kushandurwa zvinyoro..Kunwisa kasingaperi kunogona kuwedzera kukora kwetini layer.

Zvekungwaririra
Iyo copper workpiece mushure meiyo micro-etching inofanirwa kuiswa mutin plating mhinduro munguva mushure mekugezwa kudzivirira nzvimbo yemhangura kubva pakuiswa oxidized zvakare uye kukanganisa kunaka kwekuputira.

Kana iyo tinning inoshanda ichidonha, 1.0% tinning additive inogona kuwedzerwa, uye inogona kushandiswa mushure mekusimudzira zvakaenzana.
