Ubwoko bwinshi bwibikoresho fatizo bikoreshwa mugutunganya ibicuruzwa bya SMT. Tinnote nimwe mubyingenzi. Ubwiza bwa tin paste buzagira ingaruka kuburyo butaziguye bwo gusudira kwa SMT. Hitamo ubwoko butandukanye bwa tinnuts. Reka mbamenyeshe muri make amabati asanzwe:
Isupu ya Weld ni ubwoko bwa pulp yo kuvanga ifu yo gusudira hamwe na paste imeze nka paste (rosin, diluent, stabilisateur, nibindi) hamwe numurimo wo gusudira. Kubijyanye n'uburemere, 80 ~ 90% ni ibyuma bivangwa n'ibyuma. Kubijyanye nubunini, ibyuma nugurisha bingana na 50%.
Igishushanyo cya 3 Paste granules (SEM) (hejuru)
Igishushanyo 4 Igishushanyo cyihariye cya pine yifu yububiko hejuru (hepfo)
Umugurisha paste nuwitwara amabati yifu. Itanga uburyo bwiza bwo kwangirika nubushuhe kugirango bitezimbere ubushyuhe mukarere ka SMT kandi bigabanye uburemere bwamazi hejuru ya weld. Ibikoresho bitandukanye byerekana imirimo itandukanye:
1. Gutondekanya ukurikije ibigize amabati
1. Irashobora gukoreshwa mubicuruzwa bimwe bya elegitoronike bidafite ibisabwa mu kurengera ibidukikije.
2. Kurongora -ubusa bwubusa: Ibigize ibidukikije byangiza ibidukikije kandi bifite ingaruka nke. Ikoreshwa mubicuruzwa bya elegitoroniki bitangiza ibidukikije. Hamwe nogutezimbere ibisabwa byo kurengera ibidukikije mukurengera ibidukikije, kuyobora-tekinoroji yubusa mu nganda zitunganya SMT bizaba inzira.
2. Gutondekanya ukurikije ingingo yo gushonga ya tin paste
Muri rusange, ingingo yo gushonga ya tin paste irashobora kugabanywamo ubwoko butatu: ubushyuhe bwo hejuru, ubushyuhe bwo hagati, nubushyuhe buke.
Ubushyuhe bukunze gukoreshwa ni SN-G-CU 305, 0307; ubushyuhe bwo hagati bufite SN-BI-AG; ubushyuhe buke busanzwe bukoreshwa SN-BI. Muri SMT gutunganya patch, ugomba guhitamo ukurikije ibiranga ibicuruzwa bitandukanye.
3. Kugabanywa ukurikije ubwiza bwifu ya tin
Ukurikije umurambararo wibice byifu y amabati, paste yamabati irashobora kugabanywamo ibara ryijimye rya 1, 2, 3, 4, 5, na 6, murirwo 3, 4, na 5 arizo zikoreshwa cyane. Ibicuruzwa byinshi bisobanutse neza, ifu y amabati igomba kuba nto, ariko ntoya ya pine yamabati, ihwanye na okiside yifu ya tin iziyongera. Mubyongeyeho, ifu yizunguruka izafasha kuzamura ireme ryicapiro.
No 3 Umufana: Igiciro kirahendutse, gikunze gukoreshwa mubikorwa binini bya SMT;
No 4 Umufana: Bikunze gukoreshwa mugutunganya ibirenge bifatanye IC na SMT chip;
Umufana 5: Bikunze gukoreshwa mubintu bisobanutse neza byo gusudira, terefone igendanwa, tableti, nibindi, nibisabwa cyane kubisabwa cyane; biragoye cyane gutunganya ibicuruzwa bya patch ya SMT, nibyingenzi guhitamo paste ya sakotike. Fasha kunoza inzira yo gutunganya patch ya SMT.
