Zida zambiri zamagetsi sizinakhazikitsidwebe pamtunda pogwiritsa ntchito SMD.Pachifukwa ichi, SMT iyenera kukhala ndi zigawo zina zapabowo.Zigawo zokwera pamwamba, zogwira ntchito ndi zopanda pake, zikaphatikizidwa ku gawo lapansi, zimapanga mitundu itatu ikuluikulu ya misonkhano ya SMT - yomwe imatchedwa Type I, Type II ndi Type III.Mitundu yosiyanasiyana imakonzedwa mosiyanasiyana, ndipo mitundu yonse itatu imafunikira zida zosiyanasiyana.
1. Misonkhano yamtundu wa III SMT imakhala ndi zigawo zokwera pamwamba (resistors, capacitors ndi transistors) zomatira pansi.
Zida za 2.Type I zili ndi zigawo zokwera pamwamba zokha.Zigawo zimatha kukhala mbali imodzi kapena ziwiri.
3. Magawo a Type II ndi ophatikiza a Type III ndi Type I. Nthawi zambiri amakhala opanda zida zilizonse zoyikira pamwamba pamunsi, koma zimatha kukhala ndi zida zoyikira pamwamba pamunsi.
Ngati phula ndi lalikulu komanso labwino, zovuta za msonkhano wa SMT mu zipangizo zamagetsi zidzawonjezeka.
Ultra-fine pitch, QFP (Quad Flat Pack), TCP (Tape Carrier Package) kapena BGA (Ball Grid Array) ndi zigawo zazing'ono kwambiri za chip (0603 kapena 0402 kapena zazing'ono) zimagwiritsidwa ntchito pazinthu izi komanso zachikhalidwe (50 mil pitch. )) phukusi lokwera pamwamba.
Njira zopangira zida zonse zitatu zapamtunda zimaphatikizapo - zomatira, zomatira, phala la solder, kuyika, kugulitsa ndi kuyeretsa ndikutsata kuyendera, kuyesa ndi kukonza.
Chengyuan Industrial Automation, akatswiri opanga zida za SMT.
