Ob chav sided sib xyaw txheej txheem ntawm SMT

A: incoming inspection => PCB's B-side patch glue => patch => curing => flap => A-side PCB plug => wave soldering => 

cleaning => test =>rov ua dua

Tom qab muab tshuaj txhuam ua ntej, haum rau SMD cov khoom ntau dua li cov khoom sib cais

B: incoming inspection => PCB A-side insert (pinning) => flap => PCB B-side spot adhesive => patch => curing => flap => 

wave soldering => cleaning => Test =>Rework Post-insertion thiab post-fitting, haum rau kev sib cais ntau yam

tshaj SMD cov khoom

C: incoming material inspection => PCB's A surface silk screen solder paste => patch =>

drying => reflow soldering => plug-in, pin bending => flap => PCB B surface patch glue => Patch => Curing => Flap =>

 Wave Soldering => Cleaning => Detection =>Rework A nto sib xyaw, B nto mount. ?

D: incoming inspection => PCB's B side spot adhesive => patch => curing => flap =>PCB's Ib sab silk screened solder paste

=> patch => A side reflow => plug-in => B-side wave soldering => cleaning => test =>rework A-sab sib tov, B-sab mounting.

Thawj SMD, reflow, post-fabrication, yoj soldering

E: incoming inspection => PCB side B silk screen solder paste (point mount glue) => patch => drying (curing) => reflow soldering => 

flap => PCB side A silk screen solder paste => Patch => Drying = Reflow soldering 1 (local soldering can be used) => Plug-in => 

Wave soldering 2 (If there are few components, you can use manual soldering) => Cleaning => Test =>Rework A nto mount,
