Ibikenewe kurikugurisha PCBimbaho ​​zumuzunguruko

1.Gusudira bigomba kugira gusudira neza

Ibyo bita solderability bivuga imikorere ya alloy ibikoresho byuma bigomba gusudwa kandi ugurisha ashobora gukora neza muburyo bwubushyuhe bukwiye.Ntabwo ibyuma byose bifite gusudira neza.Ibyuma bimwe na bimwe, nka chromium, molybdenum, tungsten, nibindi, bifite gusudira nabi cyane;ibyuma bimwe, nkumuringa, umuringa, nibindi, bifite gusudira neza.Mugihe cyo gusudira, ubushyuhe bwo hejuru butera firime ya oxyde hejuru yicyuma, bigira ingaruka kubudodo bwibikoresho.Kugirango tunonosore ibicuruzwa, amabati yo hejuru, isahani ya feza nizindi ngamba zirashobora gukoreshwa kugirango wirinde okiside yibintu.

2.Ubuso bwo gusudira bugomba guhorana isuku

Kugirango ugere ku kintu cyiza cyo kugurisha no gusudira, ubuso bwo gusudira bugomba guhorana isuku.Ndetse no gusudira hamwe nogusudira neza, firime ya oxyde hamwe namavuta yangiza yangiza bishobora gukorerwa hejuru yubudodo kubera kubika cyangwa kwanduza.Filime yumwanda igomba gukurwaho mbere yo gusudira, bitabaye ibyo ubwiza bwo gusudira ntibushobora kwizerwa.Ibice byoroheje bya oxyde hejuru yicyuma birashobora gukurwaho na flux.Ubuso bw'ibyuma hamwe na okiside ikabije bigomba gukurwaho hakoreshejwe uburyo bwa mashini cyangwa imiti, nko gusiba cyangwa gutoragura.

3. Koresha flux ikwiye

Imikorere ya flux nugukuraho firime ya oxyde hejuru ya weldment.Uburyo butandukanye bwo gusudira busaba ibintu bitandukanye, nka nikel-chromium alloy, ibyuma bitagira umwanda, aluminium nibindi bikoresho.Biragoye kugurisha udafite flux yihariye yabugenewe.Iyo gusudira ibicuruzwa bya elegitoronike neza nkibibaho byanditseho imizunguruko, kugirango ubashe gusudira byizewe kandi bihamye, flux ishingiye kuri rosin.Mubisanzwe, inzoga zikoreshwa mugushonga rozine mumazi ya rosin.

4. Gusudira bigomba gushyukwa n'ubushyuhe bukwiye

Mugihe cyo gusudira, imikorere yingufu zumuriro nugushonga uwagurishije no gushyushya ikintu cyo gusudira, kugirango amabati hamwe na atome ya sisitemu ibone imbaraga zihagije zo kwinjira mumurongo wa kirisiti hejuru yicyuma kugirango usudwe kugirango ube umusemburo.Niba ubushyuhe bwo gusudira buri hasi cyane, bizabangamira kwinjira kwa atome zagurishijwe, bigatuma bidashoboka gukora amavuta, kandi biroroshye gukora umugurisha wibinyoma.Niba ubushyuhe bwo gusudira buri hejuru cyane, uwagurishije azaba ari muri eutectic, yihutishe kubora no guhindagurika kwa flux, bigatuma ubwiza bwumugurisha bwangirika, kandi mubihe bikomeye, Birashobora gutera amakariso kumpapuro. ikibaho cyumuzunguruko kugwa.Igikwiye gushimangirwa ni uko atari ugurisha gusa agomba gushyuha kugirango ashonge, ariko gusudira bigomba no gushyukwa nubushyuhe bushobora gushonga uwagurishije.

5. Igihe gikwiye cyo gusudira

Igihe cyo gusudira bivuga igihe gikenewe kugirango impinduka zumubiri nubumara mugihe cyose cyo gusudira.Harimo igihe cyicyuma cyo gusudira kugirango kigere ku bushyuhe bwo gusudira, igihe cyo gushonga k'umugurisha, igihe flux ikora nigihe cyo kuvanga ibyuma.Nyuma yubushyuhe bwo gusudira bumaze kugenwa, igihe gikwiye cyo gusudira kigomba kugenwa ukurikije imiterere, imiterere, nibiranga ibice bigomba gusudwa.Niba igihe cyo gusudira ari kirekire, ibice cyangwa ibice byo gusudira bizangirika byoroshye;niba igihe cyo gusudira ari gito cyane, ibisabwa byo gusudira ntibizuzuzwa.Mubisanzwe, igihe ntarengwa kuri buri ugurisha hamwe gusudira ntabwo kirenze amasegonda 5.
