Ezinye izakhi ze-SMD zincane kakhulu futhi akulula ukuzihlola futhi zilungiswe ngamapeni ajwayelekile e-multimeter. Enye iwukuthi kulula ukubangela isifunda esifushane, kanti enye iwukuthi ayihambisani nebhodi lesifunda eliboshwe nge-insulating coating ukuze lithinte ingxenye yensimbi yephini lengxenye. Nansi indlela elula yokutshela wonke umuntu, izoletha lula kakhulu ekutholeni.

Thatha izinaliti zokuthunga ezimbili ezincane kunazo zonke, (i-Deep Industrial Control Maintenance Technology Column), zivale epeni le-multimeter, bese uthatha ucingo lwethusi oluncane olusuka ekhebula elinemicu eminingi, bese ubopha ipeni nenaliti yokuthunga kuNdawonye, ​​sebenzisa i-solder. ukuze solder ngokuqinile. Ngale ndlela, abukho ubungozi bokujikeleza okufushane lapho ukala lezo zingxenye ze-SMT ngepeni lokuhlola elinetiphu yenaliti elincane, futhi ithiphu yenaliti ingabhoboza i-insulating coating futhi inqamule izingxenye ezibalulekile ngokuqondile, ngaphandle kokukhathazeka ngokukhuhla ifilimu. .
