1. Liyini Igolide Lokucwiliswa?
Ukukubeka kalula, ukucwiliswa kwegolide ukusetshenziswa kwe-chemical deposition ukukhiqiza i-metal coating ebusweni bebhodi lesifunda ngokusebenzisa ukusabela kokunciphisa i-chemical oxidation.
2. Kungani kudingeka sicwilise igolide?
Ithusi ebhodini lesifunda ngokuyinhloko liyithusi elibomvu, futhi amalunga e-solder yethusi afakwa kalula emoyeni, okuzokwenza ukuthi kube ne-conductivity, okungukuthi, ukudla okungalungile kwe-tin noma ukuthintana okungalungile, futhi kunciphise ukusebenza kwebhodi lesifunda.
Khona-ke kuyadingeka ukwenza ukwelashwa okungaphezulu kumajoyini e-solder yethusi. Ukucwiliswa kwegolide wukunamathisela igolide kuso. Igolide lingavimba ngokuphumelelayo insimbi yethusi nomoya ukuvimbela i-oxidation. Ngakho-ke, i-Immersion Gold iyindlela yokwelapha ye-surface oxidation. Kuyinto yokusabela kwamakhemikhali ethusi. Ingaphezulu limbozwe ungqimba lwegolide, olubizwa nangokuthi igolide.
3. Yiziphi izinzuzo zokwelashwa okungaphezulu njengegolide lokucwiliswa?
Inzuzo yenqubo yegolide yokucwiliswa ukuthi umbala ofakwe phezulu uzinzile kakhulu lapho isifunda sinyatheliswa, ukukhanya kuhle kakhulu, ukumboza kubushelelezi kakhulu, futhi ukuthengiselana kuhle kakhulu.
Igolide lokucwiliswa ngokuvamile linogqinsi oluyi-1-3 Uinch. Ngakho-ke, ubukhulu begolide obukhiqizwa indlela yokwelapha engaphezulu ye-Immersion Gold ngokuvamile bushubile. Ngakho-ke, indlela yokwelapha engaphezulu ye-Immersion Gold ivame ukusetshenziswa kumabhodi abalulekile, amabhodi eminwe yegolide namanye amabhodi wesifunda. Ngoba igolide line-conductivity eqinile, ukumelana okuhle kwe-oxidation kanye nempilo ende yesevisi.
4. Yiziphi izinzuzo zokusebenzisa ibhodi lesekhethi yegolide yokucwiliswa?
1. Ipuleti legolide lokucwiliswa linombala ogqamile, lihle ngombala futhi liyakhanga ngokubukeka.
2. Isakhiwo sekristalu esakhiwe ngegolide lokucwiliswa kulula ukusishisela kunezinye izindlela zokwelapha ezingaphezulu, singasebenza kangcono futhi siqinisekise ikhwalithi.
3. Ngenxa yokuthi ibhodi legolide lokucwiliswa line-nickel negolide kuphela ku-pad, ngeke lithinte isignali, ngoba ukudluliswa kwesignali emthelela wesikhumba kusengqimbeni lwethusi.
4. Izakhiwo zensimbi zegolide zizinzile, ukwakheka kwekristalu kuminyene, futhi ukusabela kwe-oxidation akulula ukwenzeka.
5. Njengoba ibhodi legolide lokucwiliswa linama-nickel negolide kuphela kumapads, imaski ye-solder kusekethe kanye nongqimba lwethusi kuhlanganiswe ngokuqinile, futhi akulula ukudala ama-circuits amancane.
6. Iphrojekthi ngeke ithinte ibanga ngesikhathi sokunxeshezelwa.
7. Ukucindezeleka kwepuleti legolide lokucwiliswa kulula ukulawula.
5. Ukucwiliswa kweminwe yegolide negolide
Iminwe yegolide iqonde kakhudlwana, iwukuxhumana kwethusi, noma abaqhubi.
Ukucacisa kakhudlwana, ngenxa yokuthi igolide linokumelana ne-oxidation okuqinile kanye ne-conductivity enamandla, izingxenye ezixhunywe kusokhethi yememori ku-memory stick zigcwele igolide, bese wonke amasignali adluliselwa ngeminwe yegolide.
Ngenxa yokuthi umunwe wegolide wakhiwe ngokuthintana okuphuzi okuphuzi, indawo engaphezulu ihlanganiswe negolide futhi okuxhunywayo kuhlelwe njengeminwe, yingakho igama.
Ngokwamagama abantu abavamile, umunwe osagolide uyingxenye exhumanisayo phakathi kwe-memory stick kanye ne-memory slot, futhi wonke amasignali adluliselwa ngomunwe osagolide. Umunwe wegolide wakhiwe ngokuthintana kwegolide okuningi. Umunwe wegolide empeleni umbozwe ungqimba lwegolide ebhodini elinezindwangu zethusi ngenqubo ekhethekile.
Ngakho-ke, umehluko olula ukuthi ukucwiliswa kwegolide kuyinqubo yokwelashwa okungaphezulu kwamabhodi esekethe, futhi iminwe yegolide iyizici ezinoxhumano lwesignali kanye nokuqhutshwa kwebhodi lesifunda.
Emakethe yangempela, iminwe yegolide ingase ingabi igolide phezulu.
Ngenxa yentengo ebizayo yegolide, izinkumbulo eziningi manje sezithathelwa indawo yi-tin plating. Izinto zikathayela bezidumile kusukela ngeminyaka yawo-1990s. Njengamanje, "iminwe yegolide" yama-motherboards, inkumbulo namakhadi wezithombe cishe zonke zenziwe nge-tin. Izinto zokwakha, ingxenye kuphela yezindawo zokuxhumana zamaseva/iziteshi zokusebenza ezisebenza kahle zizoqhubeka nokunameka ngegolide, okumba eqolo ngokwemvelo.
