Zvimwe zvikamu zveSMD zvidiki uye zvinonetsa kuyedza nekugadzirisa neakajairwa multimeter peni. Imwe ndeyokuti zviri nyore kukonzera kupfupika kwedunhu, uye imwe yacho ndeyokuti hazvina kukodzera kuti bhodhi redunhu rakaputirwa ne-insulating coating kuti ribate chikamu chesimbi chechikamu chepini. Heino nzira iri nyore yekuudza munhu wese, zvinounza zvakawanda nyore pakuonekwa.

Tora tsono mbiri diki dzekusonesa, (Deep Industrial Control Maintenance Technology Column), dzivhare kune multimeter pen, wotora waya yakatetepa yemhangura kubva kune yakawanda-strand tambo, uye sunga chinyoreso netsono yekusonesa kuPamwechete, shandisa solder. kuti solder zvakasimba. Nenzira iyi, hapana njodzi yekupfupika kwedunhu pakuyera izvo zvikamu zveSMT nepeni yekuyedza ine diki tsono, uye tsono inopinza inogona kubaya insulating coating uye gondohwe zvikamu zvakakosha zvakananga, pasina kunetseka kukwenya firimu. .
