Ukoresheje ubwo buhanga, ibyago byo gusibanganya birashobora kugabanuka cyane, byemeza kwizerwa nigihe kirekire cyimikorere ya PCBs ikomeye.

3.Ingamba zo kugabanya ibicuruzwa:

Nubwo ingamba zo kwirinda, PCBs rimwe na rimwe zigira delamination. Ariko, hariho ingamba nyinshi zo kugabanya

ibyo birashobora gushyirwa mubikorwa kugirango ikibazo gikemuke no kugabanya ingaruka zacyo. Izi ngamba zirimo kumenya no kugenzura,

tekinike yo gusana tekinike, guhindura ibishushanyo, no gukorana nabakora PCB.

Kumenyekanisha no kugenzura bigira uruhare runini mu kugabanya gusiba. Igenzura risanzwe hamwe nibizamini birashobora gufasha gutahura hakiri kare kugirango ibikorwa bigerweho mugihe gikwiye. Uburyo bwo kwipimisha budahwitse nka x-ray cyangwa thermografiya birashobora gutanga isesengura rirambuye ryibice bishobora gutandukanwa, byoroshye gukemura ibibazo mbere yuko biba ikibazo. Mugutahura hakiri kare, harashobora gufatwa ingamba zo gukumira ibyangiritse no kwemeza ubusugire bwa PCB.

Ukurikije urwego rwo gusiba, tekinoroji yo gusana irashobora gukoreshwa. Ubu buhanga bugenewe gushimangira uduce duto no kugarura ubusugire bwa PCB. Gutoranya guhitamo bikubiyemo gukuraho no gusimbuza ibice byangiritse bya PCB kugirango bikureho. Gutera inshinge nubundi buhanga aho imiti yihariye yinjizwa ahantu hasibwe kugirango bitezimbere ubumwe no kugarura ubusugire bwimiterere. Kugurisha hejuru birashobora kandi gukoreshwa muguhuza delamination, bityo bigashimangira PCB. Ubu buhanga bwo gusana bufite akamaro mugukemura ibibazo no gukumira ibyangiritse.

Niba gusiba bibaye ikibazo gisubirwamo, igishushanyo mbonera gishobora gukorwa kugirango ikibazo gikemuke. Guhindura igishushanyo cya PCB nuburyo bwiza bwo gukumira gusibanganya kubaho mbere. Ibi birashobora guhindura guhindura imiterere ya stack ukoresheje ibikoresho cyangwa ibihimbano bitandukanye, guhindura ubugari bwurwego kugirango ugabanye imihangayiko no guhangayika, cyangwa gushyiramo ibikoresho byongera imbaraga mubice bikomeye bikunda guseswa. Guhindura ibishushanyo bigomba gukorwa kubufatanye ninzobere kugirango habeho igisubizo cyiza cyo gukumira gusiba.

Ubufatanye nuwakoze PCB nibyingenzi kugirango bagabanye gusiba.
