Kugirango ugurishe neza ibice byububiko byububiko bwumuzunguruko, ubushyuhe bugomba kwimurirwa kumugurisha wa alloy paste kugeza igihe ubushyuhe bwabwo bugera ahantu hashushe (217 ° C kuri SAC305 ugurisha kubuntu).Amazi avanze azahuza hamwe na PCB y'umuringa hanyuma ahindurwe ivangwa rya eutectic.Igicuruzwa gikomeye cyo kugurisha kizashirwaho nyuma yo gukonja munsi yikintu gishongeshejwe.
Hariho uburyo butatu bwo kohereza ubushyuhe buturuka kubushyuhe kubintu bishyushye.
- Imyitwarire: Imiyoboro yubushyuhe yanduza mu buryo butaziguye ibintu iyo hari itandukaniro ryubushyuhe hagati yakarere kegeranye, nta kugenda kw'ibikoresho.Bibaho mugihe ibintu bibiri mubushyuhe butandukanye bihuye nibindi.Ubushyuhe butemba buva mubushuhe bugana ku kintu gikonje kugeza igihe byombi biri ku bushyuhe bumwe.
- Imirasire: Kohereza ubushyuhe binyuze mumirasire bibaho muburyo bwa electromagnetic waves cyane mukarere ka infragre.Imirasire nuburyo bwo guhererekanya ubushyuhe budashingiye kumikoranire iyo ari yo yose hagati yubushyuhe nibintu bishyushye.Imipaka igabanya ni uko umubiri wumukara uzakurura ubushyuhe burenze umubiri wera.
- Convection: Ubushuhe bwa convection ni ihererekanyabubasha riva ahantu hamwe ukajya ahandi hifashishijwe umuvuduko wamazi nkumwuka cyangwa umwuka wumwuka.Nuburyo kandi budahuza uburyo bwo kohereza ubushyuhe nabwo.
Umugurisha ugezwehokwerekana ifurukoresha imyumvire yimirasire hamwe na convection hamwe.Ubushyuhe butangwa nubushyuhe bwa ceramic hamwe nimirasire yimirasire, ariko ntibugeza kuri PCB muburyo butaziguye.Ubushyuhe buzajya bugenzura ubushyuhe mbere yo gukora ubushyuhe ndetse.Umufana wa convection azahuha umwuka ushyushye mubyumba byimbere.Intego PCB irashobora kubona ubushyuhe ahantu hose.
