nali igolide nethusi kumabhodi esekethe omakhalekhukhwini namakhompyutha. Ngakho-ke, intengo yokugaywa kabusha kwamabhodi esekethe asetshenzisiwe ingafinyelela ngaphezu kwamayuan angama-30 ngekhilogremu. Kubiza kakhulu kunokuthengisa amaphepha alahliwe, amabhodlela engilazi, nezinsimbi ezilahliwe.

Kusukela ngaphandle, ungqimba lwangaphandle lwebhodi lesifunda lunemibala emithathu: igolide, isiliva, nokubomvu okukhanyayo. Igolide libiza kakhulu, isiliva libiza kakhulu, futhi okubomvu okukhanyayo kubiza kakhulu.

Kungabonakala ngombala ukuthi ngabe umenzi we-hardware usike amakhona. Ngaphezu kwalokho, isifunda sangaphakathi sebhodi lesifunda ikakhulukazi ithusi elihlanzekile, elikhishwa kalula nge-oxidized uma livezwa emoyeni. Isendlalelo sangaphandle kufanele sibe nesendlalelo sokuvikela esishiwo ngenhla. Abanye abantu bathi okuphuzi kwegolide yithusi, okungalungile.

Okusagolide:

Igolide elibiza kakhulu igolide langempela. Nakuba kunongqimba oluncane kuphela, luphinde lubangele cishe u-10% wezindleko zebhodi lesifunda. Ezinye izindawo ezisogwini lwase-Guangdong naseFujian zigxile ekuthengeni amabhodi esekethe kadoti nokuxebula igolide. Inzuzo inkulu.

Kunezizathu ezimbili zokuthi kungani igolide lisetshenziswa, esinye siwukwenza lula ukushisela, kanti esinye siwukuvimbela ukugqwala.

Umunwe wegolide wemojula yenkumbulo eminyakeni engu-8 edlule usacwebezela, uma uwushintsha ube yithusi, i-aluminium, noma insimbi, uzobe ugqwalile futhi ungenamsebenzi.

Isendlalelo esinamekwe ngegolide sisetshenziswa kakhulu kumaphedi engxenye, iminwe yegolide, kanye nezinhlamvu zokuxhuma zebhodi lesifunda.
Uma uthola ukuthi amanye amabhodi esifunda ayisiliva wonke, kufanele unqume amakhona. Igama lemboni libizwa ngokuthi “costdown”.

Amabhodi omama omakhalekhukhwini ngokuvamile amabhodi agqitshwe ngegolide, kuyilapho amabhodi omama ekhompuyutha, amabhodi esekethe alalelwayo namancane edijithali ngokuvamile awawona amabhodi agqitshwe ngegolide.

Isiliva
Ingabe i-aureate eyodwa igolide nesiliva eyodwa isiliva?
Hhayi-ke, ithini.

Ibhodi lesiliva libizwa ngokuthi ibhodi le-spray tin. Ukufafaza ungqimba lukathayela ongqimbeni olungaphandle lwesekethe yethusi nakho kungasiza ekuhlanganiseni. Kodwa ayikwazi ukunikeza ukuthembeka kokuxhumana kwesikhathi eside njengegolide.

Ipuleti le-spray tin alinawo umthelela ezingxenyeni ezidayisiwe, kodwa ukwethembeka akwanele kumaphedi abekwe emoyeni isikhathi eside, njengama-grounding pads namasokhethi e-spring pin. Ukusetshenziswa isikhathi eside kuthambekele ekubeni ne-oxidation kanye nokugqwala, okuholela ekuxhumaneni okubi.

Amabhodi wesifunda wemikhiqizo emincane yedijithali, ngaphandle kokukhetha, angamabhodi e-spray tin. Kunesizathu esisodwa kuphela: ezishibhile.

Imikhiqizo emincane yedijithali ithanda ukusebenzisa ipuleti le-spray tin.

Okubomvu okukhanyayo:
I-OSP, ifilimu ye-organic soldering. Ngenxa yokuthi i-organic, hhayi insimbi, ishibhile kunokufutha ngamathini.

Okuwukuphela komsebenzi wale filimu ephilayo ukuqinisekisa ukuthi ucwecwe lwethusi lwangaphakathi ngeke lufakwe i-oxidized ngaphambi kokushisela. Lolu ngqimba lwefilimu luyahwamuka ngokushesha lapho lushiswa ngesikhathi sokushisela. I-solder ingashisela ucingo lwethusi kanye nezingxenye ndawonye.

Kodwa ayimelani nokugqwala. Uma ibhodi lesifunda le-OSP lichayeka emoyeni izinsuku eziyishumi, ngeke likwazi ukushisela izingxenye.

Amabhodi omama amaningi ekhompyutha asebenzisa ubuchwepheshe be-OSP. Ngenxa yokuthi indawo yebhodi lesifunda inkulu kakhulu, ayikwazi ukusetshenziselwa ukucwecwa kwegolide.
