Monga tonse tikudziwa, aZithunzi za SMTmakinaangagwiritsidwe ntchito kukwera mitundu yambiri ya zigawo zikuluzikulu, kotero timachitcha kuti multifunctional SMT makina, timagwiritsa ntchito ndondomeko ya SMT anthu ambiri amakhala ndi mafunso, ndi zigawo ziti zomwe zingakwezedwe?Kenako, tifotokoza mitundu inayi ya zigawo za phiri wambaPNPmakina:
- resistor: Nthawi zambiri titha kugwiritsa ntchito makina osankha ndikuyika kuyika chopinga pamwamba pa chinthucho.Kawirikawiri, tikhoza kufotokoza kukula kwamakono kwa kukana mu millimeters kapena mainchesi.Pali manambala anayi pa resistor.Ziwiri zoyamba zimayimira kutalika kwa kukana, ndipo ziwiri zomaliza zimayimira m'lifupi mwa kukana.Tikayiyikanso, bola ngati ili mkati mwazolakwika zoyika, imatha kuwonedwa ngati chinthu choyenera kuyika ndipo kugwiritsa ntchito kwake sikungakhudzidwe.
- Capacitor: pali mitundu yambiri ya ma capacitor, ma capacitor a ceramic ndi electrolytic capacitors amagwiritsidwa ntchito kwambiri.Ma capacitors ali ndi magawo anayi akuluakulu, mphamvu, kukula, zolakwika ndi coefficient.Ma capacitors amathanso kukhazikitsidwa pazigawozo pogwiritsa ntchito makina okwera.Kawirikawiri, mtengo wa capacitor wa capacitor ukhoza kuwonetsedwa mu manambala atatu pa chinthu, koma kwa ceramic capacitors, sitepe iyi ikhoza kuchotsedwa.Tikhoza kusiyanitsa ma capacitor osiyanasiyana malinga ndi mtundu, kukula ndi chitsanzo cha capacitor chomwe chinayikidwa.
- Inductance: Inductance ndi yofanana ndi mawonekedwe a capacitance, koma mtundu wakuda kuposa capacitance.Tisanakhazikitse, titha kugwiritsa ntchito chowunikira kuti tisiyanitse inductance ndi kukula kwa inductance, ndiyeno tidziwe ngati inductance yomwe idayikidwa pano ndi yofanana ndi inductance, ndipo pomaliza chip chidzakonzedwa ndi chigamba.
- Diode: diode imagwiritsidwanso ntchito kwambiri mumakampani a SMT.Magalasi ndi ma diode osindikizidwa ndi pulasitiki ndi mitundu yodziwika bwino yoyikapo ndipo amakhala ndi ntchito zambiri pamoyo watsiku ndi tsiku, monga ma LED omwe amagwiritsidwa ntchito pama foni am'manja.Ma diode azinthu zosiyanasiyana amatha kutulutsa kuwala kwamitundu yosiyanasiyana.Kuyika bwino ndi achokwera chipmakinandi njira yachidule yofikira kupanga zochuluka.
