Mazhinji emagetsi emagetsi haasati aiswa pamusoro achishandisa SMD.Nechikonzero ichi, SMT inofanirwa kugarisa mamwe maburi-maburi.Nzvimbo dzepamusoro pegomo, dzinoshanda uye dzisingaite, kana dzakabatanidzwa kune substrate, inoumba matatu makuru emhando dzeSMT magungano - anowanzo kunzi Type I, Type II uye Type III.Mhando dzakasiyana-siyana dzinogadziriswa nenzira yakasiyana, uye marudzi ose matatu anoda michina yakasiyana.
1. Type III SMT maassemblies ane chete discrete surface momo components (resistors, capacitors and transistors) zvakanamirwa kudivi rezasi.
2.Type I components ine pamusoro pegomo components chete.Zvikamu zvinogona kuva mativi maviri kana maviri-mativi.
3. Rudzi rwechipiri II musanganiswa weRudzi rwechitatu neRudzi I. Kazhinji harina chero midziyo yekumisikidza inoshanda pasi padivi, asi inogona kunge iine discrete surface mount zvishandiso padivi rezasi.
Kana iyo pitch yakakura uye yakanaka, kuoma kwemusangano we SMT mumidziyo yemagetsi kuchawedzera.
Ultra-fine pitch, QFP (Quad Flat Pack), TCP (Tape Carrier Package) kana BGA (Ball Grid Array) uye zvidiki zvikuru zvechip components (0603 kana 0402 kana zvidiki) zvinoshandiswa kune izvi zvikamu pamwe nedzechinyakare (50 mil pitch. )) pamusoro pegomo pasuru.
Maitiro ezvese matatu ekumisikidza epamusoro anosanganisira - zvinonamira, solder paste, kuiswa, kusona uye kuchenesa kunoteverwa nekuongorora, kuyedzwa uye kugadzirisa.
