Zina mwazinthu za SMD ndizochepa kwambiri komanso zovuta kuyesa ndikukonza ndi zolembera wamba zama multimeter. Chimodzi ndi chakuti n'zosavuta kuyambitsa dera lalifupi, ndipo lina ndiloti ndizovuta kuti bolodi la dera lomwe limakutidwa ndi chophimba chotetezera kukhudza gawo lachitsulo la pini ya chigawocho. Nayi njira yosavuta yowuzira aliyense, idzabweretsa kumasuka kwambiri pakuzindikira.

Tengani singano zing'onozing'ono ziwiri zosokera, (Deep Industrial Control Maintenance Technology Column), zitsekeni ku cholembera cha multimeter, kenako tengani waya woonda wamkuwa kuchokera ku chingwe chamitundu yambiri, ndikumanga cholembera ndi singano yosokera Pamodzi, gwiritsani ntchito solder. kugulitsa mwamphamvu. Mwanjira imeneyi, palibe chiopsezo chafupipafupi poyeza zigawo za SMT ndi cholembera choyesera ndi nsonga yaing'ono ya singano, ndipo nsonga ya singano imatha kuboola chophimba chotetezera ndi nkhonya mbali zazikuluzikulu mwachindunji, popanda kuvutikira kukanda filimuyo. .
