Dab tsi yog vim li cas rau rosin sib koom hauv SMT nti ua?

I. Rosin sib koom ua ke los ntawm cov txheej txheem txheej txheem
1. Tsis siv tshuaj txhuam hniav
2. Tsis txaus siv cov tshuaj txhuam hniav
3. Stencil, laus, tsis zoo to
II.Rosin sib koom ua ke los ntawm PCB yam
1. PCB pads yog oxidized thiab tsis zoo solderability

btwe ua

2. Ntawm qhov ntawm cov ntaub qhwv
III.Rosin sib koom ua ke tshwm sim los ntawm cov khoom tiv thaiv
1. Deformation ntawm cov khoom siv pins
2. Oxidation ntawm cov khoom siv pins
IV.Rosin sib koom ua ke los ntawm cov khoom siv
1. Lub mounter txav nrawm dhau ntawm PCB kis tau tus mob thiab qhov chaw, thiab qhov kev txav ntawm cov khoom hnyav yog tshwm sim los ntawm qhov loj inertia.
2. Lub SPI solder paste detector thiab AOI kuaj cov cuab yeej tsis tau kuaj xyuas qhov cuam tshuam ntawm cov tshuaj pleev xim rau txheej thiab cov teeb meem kev tso kawm hauv lub sijhawm
V. Rosin sib koom ua ke los ntawm cov khoom tsim
1. Qhov loj ntawm lub ncoo thiab cov khoom siv tus pin tsis sib xws
2. Rosin sib koom ua ke los ntawm metallized qhov ntawm lub ncoo
VI.Rosin sib koom ua ke los ntawm tus neeg teb xov tooj yam
1. Kev ua haujlwm txawv txav thaum lub sijhawm PCB ci thiab hloov pauv ua rau PCB deformation
2. Kev ua haujlwm tsis raug cai hauv kev sib dhos thiab hloov cov khoom tiav
Yeej, cov no yog cov laj thawj rau rosin pob qij txha hauv cov khoom tiav hauv PCB ua ntawm SMT thaj chaw tsim khoom.Cov kev sib txuas sib txawv yuav muaj qhov sib txawv ntawm cov pob qij txha rosin.Nws txawm tshwm sim hauv kev xav xwb, thiab feem ntau tsis tshwm sim hauv kev xyaum.Yog tias muaj qee yam tsis zoo lossis tsis raug, thov e-mail rau peb.
