The soldering ndondomeko ndi ntchito kusungunula zitsulo malata kudzaza kusiyana kugwirizana pakati pa zinthu ziwiri zitsulo kuonetsetsa kuti zinthu ziwiri zitsulo kugwirizana lonse, ndi kusunga kulimba ndi conductivity ya kugwirizana pakati pa zinthu ziwiri zitsulo. Kukhazikika kwa ndondomeko ya soldering kumagwirizana kwambiri ndi magawo okhudzana ndi ndondomeko yowonongeka, makamaka kuphatikizapo zinthu zotsatirazi: 1. Zomwe zimapangidwira pamwamba pazitsulo zazitsulo; 2. Ukhondo wa kuwotcherera pamwamba; 3. Kuchuluka kwa solder (kuchuluka kwa solder); 4. Kuwotcherera kutentha 5. Nthawi yowotcherera. The katundu wa kuwotcherera pamwamba mbali zitsulo ndi ukhondo wa kuwotcherera pamwamba akhoza bwino kulamulidwa ndi kapangidwe kamangidwe ka mankhwala. Mu soldering ochiritsira Buku, zinthu zitatu za solder kuchuluka (solder voliyumu), soldering kutentha, ndi soldering nthawi angapezeke ndi luso ntchito wa soldering opareshoni. Kugwiritsa ntchito zinachitikira ntchito kudziwa mtundu wa soldering akhoza kuchitidwa ndi fuzzy khalidwe ulamuliro. Kuwotcherera khalidwe kumakhudzidwa ndi luso mlingo wa opareshoni ndi kusinthasintha maganizo zinthu, ndipo padzakhala kusinthasintha. Kuwonongeka kwazinthu zomwe zimayambitsidwa ndi kuwotcherera kwapang'onopang'ono kumabweretsa kuchuluka kwakukulu kwazomwe zimayambitsa zovuta zamtundu wazinthu. Chifukwa chake, kugwiritsa ntchito njira zowotcherera zokha kumatha kuchepetsa kuchuluka kwa solder (kuchuluka kwa solder) mu ntchito yowotcherera, kutentha kwa kuwotcherera, ndi nthawi yowotcherera. Zinthuzi zimasinthidwa kuchoka pakupanga kuwongolera kowoneka bwino mpaka kuwongolera mwanzeru kachulukidwe. Ndilo muyeso wofunikira kwambiri kuti mutsimikizire kusasinthika ndi kukhazikika kwa mtundu wa kuwotcherera kwa zigawo zowotcherera. Kuyambira 2019, Tor Electric Company idayika ndalama kuti isinthe njira yowotcherera, idasintha kuwotcherera kwa magawo opangira ma SPD kuchokera ku kuwotcherera pamanja kupita ku makina owotcherera, ndikuwonjezera chiwopsezo cha zinthu za SPD kuchokera 95% mpaka 99.5%. Nthawi yogwira ntchito yopanda mavuto ikuwonjezeka ndi 30%, yomwe imapereka maziko abwino a teknoloji popanga zinthu za SPD ndi khalidwe lokhazikika.
