Cheebtsam ntawm SMT ntau lawm kab:

SMT ntau lawm kab muaj ib tug neeg cov khoom uas ua hauj lwm nyob rau hauv sync los xyuas kom meej ib tug du txheej txheem.Cov khoom tseem ceeb no suav nrog:

1. SMT Tshuab: Lub hauv paus ntawm lubSMT ntau lawm kabyog lub tshuab ua lub luag haujlwm muab cov khoom siv hluav taws xob tso rau ntawm PCB.Paub tias yog lub tshuab tuaj tos thiab qhov chaw, cov tshuab no siv cov cuab yeej siv hlau thiab lub tshuab nqus tsev los xaiv cov khoom siv los ntawm lub tshuab pub khoom noj thiab muab tso rau hauv PCB kom raug.

2. Reflow qhov cub: Tom qab sib dhos, PCB dhau los ntawm qhov cub reflow qhov twg cov tshuaj txhuam siv los tuav cov khoom hauv qhov chaw melts thiab solidifies, tsim kom muaj kev sib raug zoo.Lub qhov cub reflow xyuas kom meej tias cov pob qij txha tau tsim kom raug thiab cov khoom siv txuas nrog rau PCB.

3. Solder paste tshuab luam ntawv: Daim ntawv thov raug muab tshuaj txhuam yog qhov tseem ceeb rau cov txheej txheem SMT.Lub tshuab luam ntawv muab tshuaj txhuam siv cov stencil los siv cov tshuaj pleev xim rau hauv PCB, kom ntseeg tau tias kev sib raug zoo nrog cov ntaub qhwv.

4. Kev Tshuaj Ntsuam Xyuas: Yuav kom tswj tau cov qauv zoo, tag nrho cov kab ntau lawm tau txais kev tshuaj xyuas.Automated optical inspection (AOI) cov cav tov tshuaj xyuas qhov tsis xws luag xws li cov khoom uas ploj lawm los yog tsis zoo, soldering defects, thiab PCB tsis xws luag.X-ray tshuaj xyuas tshuab kuj tseem siv los txheeb xyuas qhov tsis xws luag, xws li cov pob qij txha tsis txaus.
