Impamvu nyamukuru zitera ubushyuhe butaringaniye bwibikoresho muri SMT yubusa yo kugurisha ibicuruzwa bitagabanijwe ni: ibicuruzwa bitarimo ibicuruzwa bitwara ibicuruzwa bitwara ibicuruzwa, umukandara wa convoyeur cyangwa ingaruka zishyushya, hamwe nubudasa bwubushobozi bwubushyuhe cyangwa kwinjiza ubushyuhe bwibikoresho bitagabanijwe.
ImpactIngaruka zibicuruzwa bitandukanye bipakurura.Guhindura ubushyuhe bwumurongo wa sisitemu yubusa-kugurisha kugurisha bigomba gutekereza kubisubiramo neza munsi yumutwaro, umutwaro nibintu bitandukanye.Ibintu biremereye bisobanuwe nka: LF = L / (L + S);aho L = uburebure bwa substrate yateranijwe hamwe na S = intera iri hagati yubutaka bwateranijwe.
②Mu ziko ritagira isasu ridafite isuku, umukandara wa convoyeur nawo uhinduka uburyo bwo gukwirakwiza ubushyuhe mugihe utwara ibicuruzwa inshuro nyinshi kugurisha ibicuruzwa bitarimo ibicuruzwa.Mubyongeyeho, uburyo bwo gukwirakwiza ubushyuhe buratandukanye kuruhande no hagati mugice cyo gushyushya, kandi ubushyuhe kumpera buri hasi.Usibye ubushyuhe butandukanye busabwa muri buri karere k'ubushyuhe mu itanura, ubushyuhe hejuru yumutwaro umwe nabwo buratandukanye.
③ Mubisanzwe, PLCC na QFP bifite ubushyuhe bunini burenze ibice bya chip, kandi biragoye gusudira ibice binini kuruta ibice bito.
Kugirango ubone ibisubizo bisubirwamo muburyo bwo kuyobora-kugurisha kugurishwa, uko ibintu biremereye, niko bigorana.Mubisanzwe ibintu byinshi biremereye byamashyiga-yubusa itanura hagati ya 0.5-0.9.Ibi biterwa nibicuruzwa (ibicuruzwa bigurishwa, ibice bitandukanye) hamwe nuburyo butandukanye bwitanura.Kugirango ubone ibisubizo byiza byo gusudira no gusubiramo, uburambe bufatika ni ngombwa.
