Circuit board mugadziri: oxidation kuongororwa uye nzira yekuvandudza yekunyudza goridhe pcb board?

1. Mufananidzo weImmersion Gold Board ine Yakashata Oxidation:

J[W4B~5~]8EZ3YP0~~EP@84
2. Tsananguro yeImmersion Gold Plate Oxidation:
Iyo oxidation yegoridhe-yakanyudzwa redunhu bhodhi yemugadziri wedunhu redunhu ndeyekuti pamusoro pegoridhe yakasvibiswa nekusachena, uye tsvina inonamirwa pamusoro pegoridhe inoiswa oxid uye yakasvibiswa, iyo inotungamira kune oxidation yegoridhe pamusoro iyo isu. kazhinji kufona.Muchokwadi, chirevo chegoridhe surface oxidation hachisi chokwadi.Ndarama isimbi inert uye haizove oxidized pasi pemamiriro ezvinhu.Tsvina inonamirwa pamusoro pegoridhe senge copper ions, nickel ions, microorganisms, nezvimwe zvinogadziriswa nyore nyore uye zvinoshata pasi pemamiriro akajairwa kuita goridhe usoro oxidation.Zvinhu.

3. Kuburikidza nekutarisa, zvinoonekwa kuti oxidation yekunyudza goridhe redunhu bhodhi inonyanya kuve neanotevera maitiro:
1. Kushanda zvisina kufanira kunoita kuti zvinosvibisa zvinamatire kune pamusoro pegoridhe, se: kupfeka magirovhosi ane tsvina, machira emunwe anobata pamusoro pegoridhe, ndiro yegoridhe inobata nekaunda ine tsvina, mabhegi ndiro, nezvimwewo;rudzi urwu rwe oxidation nzvimbo yakakura uye inogona kuitika panguva imwe chete Pamapedhi akawanda ari pedyo, ruvara rwekuonekwa rwakareruka uye nyore kuchenesa;
2. Half-plug gomba, diki-scale oxidation pedyo neburi;rudzi urwu rweoxidation runokonzerwa neiyo yavo mvura mugomba kana hafu-plug gomba isiri kucheneswa kana yakasara mhute yemvura mugomba, iyo mvura yavo inopararira zvishoma nezvishoma pamadziro egomba panguva yekuchengetera chigadzirwa chakapedzwa Dark brown oxide. inoumbwa pamusoro pegoridhe;
3. Hunhu husina kunaka hwemvura hunoita kuti tsvina iri mumvura inoshambadzirwe pamusoro pegoridhe, sekuti: kugezeswa mushure mekunyura kwegoridhe, kugeza newasher yeplate yakapedzwa, nzvimbo yeoxidation yakadaro idiki, inowanzoonekwa pamakona emapadhi ega ega. zvakanyanya kujeka Mavara emvura;mushure mokunge ndiro yegoridhe yashambidzwa nemvura, pachava nemadonhwe emvura padhi.Kana mvura iine tsvina yakawanda, madonhwe emvura anokurumidza kubuda uye anoderera kusvika kumakona kana kupisa kweplate kwakakwirira.Mushure mokunge mvura yapera, tsvina ichasimbisa Pamakona epadhi, iyo inonyanya kusvibisa yekugeza mushure mekunyudzwa mugoridhe uye kushambidzwa mumucheka weplate yakapedzwa ndeye microbial fungi.Kunyanya tangi ine DI mvura inonyanya kukodzera kuparadzira fungus.Iyo yakanakisa yekuongorora nzira ndeye kubata ruoko.Tarisa kana paine panotsvedza kunzwa pakona yakafa yemadziro etangi.Kana iripo, zvinoreva kuti mutumbi wemvura wakasvibiswa;
4. Kuongorora bhodhi rekudzoka kwemutengi, zvinoonekwa kuti nzvimbo yegoridhe haina kuomesesa, nickel pairi ine corroded zvishoma, uye oxidation saiti ine abnormal element Cu.Ichi chinhu chemhangura chinogona kuitika nekuda kwehurombo hunyoro hwegoridhe uye nickel uye kutama kwemaion emhangura.Mushure merudzi urwu rweoxidation yabviswa, icharamba ichikura, uye kune njodzi yekudzoreredza oxidation.
