Brazing Umunyabukorikori Bwiza bwo Kwinjira neza

Guconga ntabwo bishonga ibyuma byibanze ariko bigera kubufatanye mugushonga hasi-gushonga-ingingo ya brazing yuzuza ibyuma kugirango yuzuze icyuho. Irimo gusudira neza hamwe no guhindura ibintu bito, bigatuma bikwiranye no gusudira ibice byuzuye, ibikoresho bidasa, hamwe nuburyo bugoye. Nibyingenzi mubice nka electronics, icyogajuru, nibikoresho byubuvuzi. Ukurikije gushonga kwicyuma cyuzuza ibyuma, gushakisha bigabanyijemo ibyiciro bibiri: gusya byoroshye no gukata cyane.

(I) Brazing yoroshye: "Micro-Joining" kubikoresho bya elegitoroniki

Gukonjesha byoroheje bifashisha ibyuma byuzuza hamwe no gushonga munsi ya 450 ° C. Ibyuma bikoreshwa cyane byuzuza ibyuma ni tin-lead alloy (buhoro buhoro bisimburwa na tin-alline idafite amabati). Flux ikoreshwa mugihe cyo gusudira kugirango ikureho firime ya oxyde kandi igabanye uburemere bwubutaka. Irakwiriye guhuza neza ibice bya elegitoroniki, imbaho ​​zumuzunguruko, hamwe nuyoboro wamazi, muribyo kugurisha ni tekinoroji yoroshye yo gushakisha.

1. Kugurisha: "Ubuhanga bwibanze" bwo gusudira Ikibaho

Ihame: Icyuma kigurisha gishyushya igihangano (ubushyuhe 250-350 ° C), kigashonga insinga zidafite amashanyarazi (gushonga hafi 227 ° C). Mubikorwa bya flux, amabati yashongeshejwe yuzuza icyuho kiri hagati yipine yibigize hamwe nudupapuro twumuzunguruko, bikora umugurisha nyuma yo gukonja.

Ingingo zikoreshwa:

Isuku mbere yo gusudira: Koresha sandpaper kugirango uhanagure ibipapuro hamwe nudupapuro kugirango ukureho ibice bya oxyde; ohanagura ikibaho cyumuzunguruko n'inzoga kugirango ukureho amavuta kandi wirinde kugurisha ubukonje.

Tekinike yo Gushyushya: Banza, uzane icyuma cyo kugurisha kugirango uhuze nakazi (ihuriro rya pin na padi). Nyuma yo gushyushya amasegonda 1-2, kugaburira amabati. Irinde gushyushya mu buryo butaziguye insinga z'amabati, zishobora gutera "kugurisha imbeho" (amabati yashongeshejwe ananirwa guhanagura neza akazi).

Igenzura rihuriweho hamwe: Ingano y amabati igomba kuba "ihagije kugirango yuzuze icyuho kituzuye." Igicuruzwa kigurishwa kigomba "guhuza." Ntugahungabanye ibice mbere yo gukonja kugirango wirinde kugurisha hamwe.

Gukata cyane bifashisha ibyuma byuzuza hamwe no gushonga hejuru ya 450 ° C. Ibikunze gukoreshwa byuzuza ibyuma ni umuringa-zinc (umuringa wuzuza umuringa) hamwe nifeza ishingiye kuri feza (kuzuza ifeza). Igaragaza ubushyuhe bwo hejuru bwo gusudira hamwe nimbaraga zo gusudira cyane, bigatuma bikwiranye no gusudira ibice byimbaraga zikomeye nkibikoresho byo gukata, guhinduranya ubushyuhe, hamwe na moteri ya aero-moteri.

Ingingo zikoreshwa: Shyushya icyuma fatizo mbere yo gusudira (ubushyuhe 300-500 ° C) kugirango wuzuze neza ibyuma byuzuza; koresha flux nka borax na acide boric kugirango ukureho firime ya oxyde hejuru yicyuma; kora uburyo bwo gukonjesha buhoro nyuma yo gusudira (urugero, gushyira mu gasanduku ka insulasiyo) kugirango wirinde ibice biterwa nubushyuhe bukabije.

(III) Ingamba zo Guhitamo hamwe niterambere ryuburyo bwo gusudira

Guhura nuburyo butandukanye bwo gusudira, uburyo bwo guhitamo ikoranabuhanga rikwiranye nibikenewe nyabyo nurufunguzo rwo kuzamura ubuziranenge no gukora neza. Muri icyo gihe, hamwe n’iterambere ry’ikoranabuhanga mu nganda, ikoranabuhanga ryo gusudira naryo riragenda ryerekeza "ku bwenge no mu cyatsi."

(IV) Ibintu by'ingenzi byo guhitamo uburyo bwo gusudira

Ibiranga Ibyingenzi Ibiranga: Kubyuma bya karuboni nkeya, icyambere gihabwa SMAW na CO₂ gusudira; ibyuma bitagira umwanda, gusudira TIG hamwe no gusudira laser birahitamo; kuri aluminiyumu, AC TIG gusudira byatoranijwe; kubikoresho bya elegitoronike, kugurisha birakoreshwa.

Ibisabwa Ibicuruzwa: Kubice bisobanutse neza (nkibice byindege), gusudira laser hamwe na TIG gusudira; kubice byakozwe cyane.
