1. Chii chinonzi Immersion Gold?
Kuzvitaura zviri nyore, kunyudza goridhe ndiko kushandiswa kwemakemikari deposition kugadzira simbi yekumisikidza pamusoro pebhodhi redunhu kuburikidza nekemikari oxidation-kuderedza reaction.
2. Nei tichifanira kunyudza goridhe?
Iyo mhangura pabhodhi redunhu inonyanya tsvuku mhangura, uye majoini emhangura anotengeswa ari nyore oxidized mumhepo, izvo zvinokonzeresa conductivity, kureva, murombo tin kudya kana kutadza kuonana, uye kuderedza kushanda kwebhodhi redunhu.
Zvadaro zvakakosha kuita kurapwa kwepamusoro pamajoini emhangura solder. Ndarama inonyudzwa ndiyo yokunamira goridhe pairi. Ndarama inogona kunyatsovhara simbi yemhangura nemhepo kudzivirira oxidation. Naizvozvo, Kunyudzwa Goridhe inzira yekurapa yepasi oxidation. Ikemikari inobata pamhangura. Pamusoro pacho pakafukidzwa nejira regoridhe, rinonziwo goridhe.
3. Ndezvipi zvakanakira kurapwa kwepamusoro segoridhe rekunyudzwa?
Chakanakira kunyudzwa kwegoridhe maitiro ndechekuti ruvara rwakaiswa pamusoro rwakagadzikana zvakanyanya kana dunhu radhindwa, kupenya kwakanaka kwazvo, kupfekedza kwacho kutsetseka, uye solderability yakanaka kwazvo.
Kunyudzwa goridhe kazhinji kune ukobvu hwe1-3 Uinch. Naizvozvo, ukobvu hwegoridhe hunogadzirwa nepamusoro pekurapa nzira yeImmersion Goridhe hunowanzo kukora. Nokudaro, nzira yekurapa pamusoro peImmersion Gold inowanzoshandiswa mumabhodhi makuru, mabhodhi eminwe yegoridhe uye mamwe mabhodhi edunhu. Nekuti goridhe ine conductivity yakasimba, yakanaka oxidation kuramba uye hupenyu hurefu hwebasa.
4. Ndezvipi zvakanakira kushandisa kunyudza goridhe redunhu mabhodhi?
1. Ndiro yegoridhe yakanyudzwa inopenya muruvara, yakanaka muruvara uye inokwezva muchitarisiko.
2. Chimiro chekristaro chakaumbwa nekunyudza goridhe chiri nyore kuchinjisa pane mamwe marapirwo epamusoro, anogona kuita zvirinani uye kuve nechokwadi chemhando.
3. Nekuti kunyudzwa kwegoridhe bhodhi rine nickel negoridhe chete padhi, hazvizokanganisa chiratidzo, nekuti iyo chiratidzo chekufambisa mumhedzisiro yeganda iri pamhangura yemhangura.
4. Simbi yegoridhe zvinhu zvakadzikama, chimiro chekristaro chakanyanya, uye oxidation reactions haisi nyore kuitika.
5. Sezvo kunyudzwa kwegoridhe bhodhi kuine nickel negoridhe chete pamapadhi, solder mask padunhu uye mhangura yemhangura yakanyatsobatanidzwa, uye hazvisi nyore kukonzera micro short circuits.
6. Iyo purojekiti haizokanganisa chinhambwe panguva yekuripa.
7. Kushushikana kweplate yegoridhe yekunyudzwa kuri nyore kudzora.
5. Kunyudza zvigunwe zvegoridhe negoridhe
Zvigunwe zvegoridhe zvakanyanya kutwasanuka, zvinosanganisirwa nendarira, kana conductors.
Kuti ive yakanyatsojeka, nekuti goridhe ine yakasimba oxidation kuramba uye yakasimba conductivity, zvikamu zvakabatana nememori socket pane memory stick inoputirwa negoridhe, ipapo masaini ese anofambiswa kuburikidza neminwe yegoridhe.
Nekuda kwekuti chigunwe chegoridhe chinoumbwa nezvakawanda zveyero conductive zvinobatika, nzvimbo yacho ine goridhe-yakaputirwa uye maconductive contacts akarongwa sezvigunwe, nekudaro zita.
Mukutaura kwevasina basa, chigunwe chegoridhe ndicho chinobatanidza pakati pememory stick nememory slot, uye masaini ese anofambiswa nemunwe wegoridhe. Chigunwe chegoridhe chinoumbwa nezvakawanda zvegoridhe conductive contacts. Chigunwe chegoridhe chakanyatsonamirwa nedara regoridhe pabhodhi rakapfekedzwa copper kuburikidza nenzira yakakosha.
Naizvozvo, musiyano wakareruka ndewekuti kunyudza goridhe inzira yekurapa pamusoro pemabhodhi edunhu, uye zvigunwe zvegoridhe zvikamu zvine masaini ekubatanidza uye conduction pabhodhi redunhu.
Mumusika chaiwo, zvigunwe zvegoridhe zvingasava goridhe pamusoro.
Nekuda kwemutengo unodhura wegoridhe, ndangariro zhinji dzatsiviwa nemarata ekuputira. Tin zvinhu zvave zvakakurumbira kubva kuma1990s. Parizvino, "zvigunwe zvegoridhe" zvemabhodhi eamai, ndangariro uye makadhi emifananidzo zvinenge zvese zvakagadzirwa netini. Zvishandiso, chikamu chete chenzvimbo dzekuonana dzepamusoro-kushanda maseva / nzvimbo dzekushandira zvicharamba zvichinge zvakaputirwa negoridhe, izvo zvinodhura zvakasikwa.
