Kuthyoka kwa cholumikizira cha solder pa chopukutidwa ndi chophatikizika ndi chachilendo;mu Chithunzi 1 cholumikizira cha solder chili pa bolodi lambali imodzi.Mgwirizanowu walephera chifukwa chakukula ndi kutsika kwa lead mu olowa.Pachifukwa ichi vuto liri ndi mapangidwe oyambirira chifukwa bolodi silikukwaniritsa zofunikira za malo ake ogwirira ntchito.Magulu a mbali imodzi amatha kulephera panthawi ya msonkhano chifukwa cha kusagwira bwino ntchito koma pamenepa pamwamba pa mgwirizanowu amasonyeza mizere yopanikizika yomwe yapangidwa poyenda mobwerezabwereza.
Chithunzi 1: Mizere yopanikizika apa ikuwonetsa kuti kung'amba pa bolodi la mbali imodzi kunayambika chifukwa cha kusuntha mobwerezabwereza panthawi yokonza.
Chithunzi 2 chikuwonetsa ming'alu mozungulira tsinde la fillet ndipo yapatukana ndi mkuwa.Izi zikuyenera kukhala zogwirizana ndi zofunikira za solderability za bolodi.Kunyowetsa pakati pa solder ndi pad pamwamba sikunachitike kumabweretsa kulephera kwa mgwirizano.Kuthyoka kwa mafupa nthawi zambiri kumachitika chifukwa cha kuchuluka kwa kutentha kwa mgwirizano ndipo izi zingagwirizane ndi mapangidwe oyambirira a chinthucho.Sizofala kwambiri kulephera kuchitika lero chifukwa cha zomwe zidachitika komanso kuyezetsa koyambirira kochitidwa ndi makampani ambiri otsogola zamagetsi.
Chithunzi 2: Kupanda kunyowetsa pakati pa solder ndi pad pamwamba kunayambitsa mng'alu uwu pansi pa fillet.
