Hauv cov txheej txheem tsim khoom PCB, muaj lwm txoj kev tseem ceeb, uas yog, cov cuab yeej siv sawb.Kev tshwj tseg ntawm cov txheej txheem ntug yog qhov tseem ceeb heev rau kev ua tiav SMT tom ntej.
Cov cuab yeej sawb yog ib feem ntxiv rau ntawm ob sab lossis plaub sab ntawm PCB lub rooj tsavxwm, feem ntau yog los pab SMT plug-in rau vuam tawm ntawm lub rooj tsavxwm, uas yog, los pab txhawb SMT SMT tshuab khiav clamp lub PCB board thiab ntws los ntawm lub rooj tsavxwm. SMT tshuab SMT.Yog tias cov khoom nyob ze rau ntawm ntug kev nqus cov khoom hauv SMT SMT lub tshuab nozzle thiab muab tso rau hauv PCB pawg thawj coj saib, qhov tshwm sim kev sib tsoo yuav tshwm sim.Raws li qhov tshwm sim, kev tsim khoom tsis tuaj yeem ua tiav, yog li yuav tsum tau khaws ib lub cuab yeej tshwj xeeb, nrog rau qhov dav dav ntawm 2-5mm.Txoj kev no kuj tsim nyog rau qee cov khoom siv plug-in, tom qab yoj soldering los tiv thaiv cov xwm txheej zoo sib xws.
Cov cuab yeej siv tsis yog ib feem ntawm PCB pawg thawj coj saib thiab tuaj yeem raug tshem tawm tom qab kev tsim khoom ntawm PCBA tiav

Txoj kev ntawmtsim cov cuab yeej sawb:
1, V-CUT: txheej txheem kev sib txuas ntawm cov cuab yeej sawb thiab lub rooj tsavxwm, txiav me ntsis ntawm ob sab ntawm PCB pawg thawj coj saib, tab sis tsis txiav!
2, Txuas cov tuav: siv ob peb txoj hlua txuas rau PCB pawg thawj coj saib, ua qee qhov thwj qhov hauv nruab nrab, kom txhais tes tuaj yeem tawg lossis ntxuav nrog lub tshuab.

Tsis yog tag nrho cov PCB boards yuav tsum tau ntxiv tooling sawb, yog hais tias lub PCB board qhov chaw loj, tsis muaj thaj tsam li ntawm 5 hli ntawm ob sab ntawm lub PCB, nyob rau hauv cov ntaub ntawv no, tsis muaj yuav tsum tau ntxiv tooling sawb, kuj muaj ib tug ntau ntawm cov ntaub ntawv. pcb board tsis pub dhau 5 hli ntawm ib sab ntawm tsis muaj thaj chaw, tsuav yog ntxiv cov cuab yeej siv rau sab nraud.Cov no xav tau kev saib xyuas ntawm PCB engineer.

Lub rooj tsavxwm siv los ntawm cov cuab yeej siv yuav ua rau tus nqi tag nrho ntawm PCB, yog li nws yog qhov tsim nyog los sib npaug kev lag luam thiab kev tsim khoom thaum tsim PCB txheej txheem ntug.
 
Rau qee qhov tshwj xeeb zoo li PCB pawg thawj coj saib, PCB pawg thawj coj saib nrog 2 lossis 4 lub cuab yeej siv tau yooj yim heev los ntawm kev sib sau ua ke ntawm pawg thawj coj saib.
 
Hauv kev ua SMT, tus qauv tsim ntawm lub piecing hom yuav tsum coj tag nrho tus account ntawm txoj kab dav ntawm SMT piecing tshuab.Rau lub piecing board nrog ib tug dav tshaj 350mm, nws yog tsim nyog los sib txuas lus nrog SMT tus neeg muag khoom tus txheej txheem engineer.
