Ntau cov khoom siv hluav taws xob tseem tsis tau muaj qhov chaw siv SMD.Vim li no, SMT yuav tsum ua raws li qee qhov ntawm lub qhov.Surface mount Cheebtsam, nquag thiab passive, thaum txuas mus rau lub substrate, tsim peb lub ntsiab ntawm SMT cov rooj sib txoos - feem ntau hu ua Hom I, Hom II thiab Hom III.Cov ntau yam yog ua tiav nyob rau hauv ib qho kev txiav txim sib txawv, thiab tag nrho peb hom yuav tsum muaj cov khoom sib txawv.
1. Hom III SMT cov rooj sib txoos tsuas muaj cov khoom sib cais ntawm qhov sib txawv (resistors, capacitors thiab transistors) glued rau sab hauv qab.
2.Type I Cheebtsam muaj cov khoom siv saum npoo av nkaus xwb.Cheebtsam tuaj yeem yog ib sab lossis ob sab.
3. Hom II Cheebtsam yog kev sib xyaw ua ke ntawm Hom III thiab Hom I. Nws feem ntau tsis muaj cov khoom siv sab hauv qab, tab sis tuaj yeem muaj cov khoom siv sib cais ntawm sab hauv qab.
Yog tias lub suab loj thiab zoo, qhov nyuaj ntawm SMT sib dhos hauv cov khoom siv hluav taws xob yuav nce ntxiv.
Ultra-fine pitch, QFP (Quad Flat Pack), TCP (Cov Kab Ntsig Carrier Package) lossis BGA (Ball Grid Array) thiab cov nti me me (0603 lossis 0402 lossis me dua) yog siv rau cov khoom no nrog rau cov tsoos (50 mil suab) )) nto mount pob.
Cov txheej txheem rau tag nrho peb qhov chaw mounts suav nrog - nplaum, solder paste, tso, soldering thiab tu tom qab los ntawm kev tshuaj xyuas, kuaj thiab kho
