Hariho uburyo bubiri bwingenzi bwo kugurisha mubucuruzi - kugarura no kugurisha imiraba.
Kugurisha umuraba birimo kunyuza kugurisha ku kibaho gishyushye.Ubushyuhe bwibibaho, gushyushya no gukonjesha imyirondoro (itari umurongo), ubushyuhe bwo kugurisha, imiterere yumurongo (uniforme), igihe cyo kugurisha, umuvuduko w umuvuduko, umuvuduko wibibaho, nibindi byose nibintu byingenzi bigira ingaruka kubisubizo byagurishijwe.Ibice byose byubushakashatsi, imiterere, imiterere ya padi nubunini, gukwirakwiza ubushyuhe, nibindi bigomba gusuzumwa neza kubisubizo byiza byo kugurisha.
Biragaragara ko kugurisha imiraba ari inzira ikaze kandi isaba - none kuki ukoresha ubu buryo bwose?
Irakoreshwa kuko nuburyo bwiza kandi buhendutse buraboneka, kandi rimwe na rimwe uburyo bwonyine bufatika.Iyo ibice byanyuze mu mwobo bikoreshwa, kugurisha umurongo ni uburyo bwo guhitamo.
Kugurisha ibicuruzwa bivuga gukoresha ikoreshwa rya paste (imvange yuwagurishije na flux) kugirango uhuze ikintu kimwe cyangwa byinshi bya elegitoronike kuri paje yo guhuza, no gushonga uwagurishije akoresheje ubushyuhe bugenzurwa kugirango agere kubufatanye buhoraho.Amatanura yerekana arashobora gukoreshwa, amatara yo gushyushya infragre cyangwa imbunda yubushyuhe nubundi buryo bwo gushyushya bwo gusudira.Kugurisha ibicuruzwa bifite ibisabwa bike kumiterere ya padi, igicucu, icyerekezo cyubuyobozi, imiterere yubushyuhe (biracyafite akamaro kanini), nibindi. Kubice bigize ibice byubuso, mubisanzwe ni byiza cyane - kugurisha no kuvanga flux byabanje gukoreshwa na stencil cyangwa ibindi uburyo bwikora, nibigize bigashyirwa mumwanya kandi mubisanzwe bifatwa mumwanya wa paste.Ibifatika birashobora gukoreshwa mugihe gisaba ibintu, ariko ntibikwiranye nibice byacukuwe - mubisanzwe kugaruka ntabwo aribwo buryo bwo guhitamo ibice byacukuwe.Ikibaho cyinshi cyangwa cyinshi cyane gishobora gukoresha uruvange rwo kugurisha no kugurisha imiraba, hamwe nibice byayoboye byashyizwe kuruhande rumwe rwa PCB (bita uruhande A), kuburyo bishobora kuzunguruka kugurisha kuruhande B. Aho igice cya TH kiri Kwinjizamo mbere yuko igice cyanyuze mu mwobo cyinjizwamo, ibice birashobora kugarurwa kuruhande A.Ibice byinyongera bya SMD birashobora noneho kongerwaho kuruhande rwa B kugirango bizunguruke hamwe nibice bya TH.Abifuza cyane kugurisha insinga ndende barashobora kugerageza kuvanga ibintu bigoye bigurisha ahantu hatandukanye, bigatuma uruhande B rugaruka mbere cyangwa nyuma yo kugurisha imiraba, ariko ibi ntibisanzwe.
Kugaragaza tekinoroji yo kugurisha ikoreshwa kubice byo hejuru.Mugihe ibyapa byinshi byumuzunguruko bishobora guteranyirizwa mukiganza ukoresheje icyuma cyagurishijwe hamwe ninsinga zagurishijwe, inzira iratinda kandi ikibaho cyavuyemo kirashobora kutizerwa.Ibikoresho bigezweho byo guteranya PCB bifashisha kugurisha cyane cyane kugirango bibyare umusaruro mwinshi, aho imashini zitoragura-zigashyira ibice ku mbaho, zometseho paste yo kugurisha, kandi inzira zose zikaba zikora.
