SMT Ua / Patch Ua Cov Txheej Txheem Hauv Txheej txheem

Cov txheej txheem yooj yim ntawm cov smt ua / thaj ua:

Silk Screen (lossis Dispensing) -> Mounting -> (Curing) -> Reflow Soldering -> Kev Tu -> Kev Kuaj -> Rework

Txhob lo lo ntxhuav vijtsam: Nws txoj haujlwm yog luam tawm cov tshuaj pleev txhuam cov kabmob lossis cov kua nplaum ntawm lub ncoo ntawm PCB los npaj rau soldering ntawm Cheebtsam. Cov khoom siv siv yog tshuab luam ntawv tshuab luam ntawv (tshuaj ntsuam tshuab luam ntawv), nyob ntawm thawj ntawm SMT cov kab ntau lawm.

Kev faib tawm: Nws yog kua nplaum uas poob kua nplaum rau qhov chaw ruaj ntawm PCB. Nws lub ntsiab muaj nuj nqi yog txhim kho cov Cheebtsam rau PCB. Cov cuab yeej siv yog lub tshuab faib tawm nyob ntawm thawj ntawm kab SMT lossis tom qab cov khoom siv tshuaj xyuas.

Pob Ntseg: Nws txoj haujlwm yog txhawm rau ua kom qhov chaw ruaj ruaj ntawm cov nplooj ntawv txuas mus rau qhov chaw ruaj ruaj ntawm PCB. Cov khoom siv siv yog ib qho chaw tso khoom siv nyob hauv qab lub tshuab luam ntawv tshuaj ntsuam hauv SMT cov kab ntau lawm.

Kev tua: Nws txoj haujlwm yog kom yaj lub ntsej muag nplaum, kom cov txheej txheem saum npoo thiab PCB pawg tswj hwm tau ruaj khov ua ke. Cov cuab yeej siv yog lub qhov cub curing nyob sab tom qab qhov kev tso kawm tshuab hauv SMT kab.

Reflow soldering: Lub luag haujlwm yog ua kom yaj cov hmoov txhuam, kom cov nplaim hluavtaws saum npoo thiab PCB pawg thawj coj saib kev ntseeg tau zoo ua ke. Cov cuab yeej siv yog lub qhov cub reflow uas nyob tom qab lub tshuab tso rau hauv kab SMT.

Kev Tu Kom Huv: Cov nuj nqi yog tshem tawm cov vuam seem (xws li flux) uas muaj kev phom sij rau tib neeg lub cev ntawm PCB sib dhos. Cov cuab yeej siv yog tshuab ntxhua khaub ncaws, txoj haujlwm tuaj yeem tsau tau, nws tuaj yeem online lossis tsis tau.
