Kukikugurisha ibicuruzwabita "kugarura"?Kugaragaza kugurisha kugurisha bivuze ko nyuma yakugurishaagera aho ashonga ya paste yagurishijwe, munsi yibikorwa byuburemere bwubuso bwamabati yamazi na flux, amabati yamazi asubira mumapine yibigize kugirango agire ingingo zigurisha, byemerera umuzenguruko Inzira ikorwamo ibibaho hamwe nibigize. kugurishwa muri rusange nabyo byitwa inzira yo "kugarura".
1. Iyo ikibaho cya PCB cyinjiye mukarere gashyushya ubushyuhe, umusemburo na gaze muri paste yabagurisha bigenda.Muri icyo gihe, flux muri paste yagurishije ihanagura amakariso, ibice birangirana na pin, hanyuma paste yuwagurisha yoroshye kandi irasenyuka., Gupfuka padi, gutandukanya padi hamwe nibice bigize ogisijeni.
2. Iyo akanama k'umuzunguruko ka PCB kinjiye mu gice cyo kugurisha ibicuruzwa, PCB n'ibigize birashyuha rwose kugirango PCB itinjira mu buryo butunguranye ahantu h'ubushyuhe bwo hejuru bwo gusudira no kwangiza PCB n'ibigize.
3. Iyo PCB yinjiye ahantu hagurishirizwa ibicuruzwa, ubushyuhe burazamuka vuba kuburyo paste yuwagurishije igera kumiterere yashongeshejwe, kandi uwagurishije amazi atose kandi agakwirakwiza amakariso, ibice byanyuma nibipapuro bya PCB, kandi amabati yamazi aragaruka akivanga. gushiraho abagurisha ingingo.
4. PCB yinjira muri zone ikonjesha, kandi amabati y'amazi aragaruka kugirango akomeze ingingo zagurishijwe n'umwuka ukonje wo kugurisha;muri iki gihe, kugurisha kugarura birarangiye.
Igikorwa cyose cyo kugurisha ibicuruzwa ntigishobora gutandukana numwuka ushushe mu itanura ryerekana.Kugurisha kugurisha gushingira kubikorwa byumuyaga ushushe kubicuruzwa.Amazi ameze nka jelly akora reaction yumubiri munsi yubushyuhe bwo hejuru bwikirere kugirango agere kuri SMD;kugurisha ibicuruzwa ”
