Lub tshuab tuaj tos thiab qhov chaw yog ib qho tseem ceeb ntawm cov cuab yeej siv hauv tshuab mounting tshuab (SMT) rau cov khoom siv hluav taws xob. Nws txoj hauv kev ua haujlwm suav nrog kev siv lub tshuab hluav taws xob thiab kev tswj xyuas hluav taws xob kom khaws cov khoom siv hluav taws xob (xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov hluav taws xob sib txuas) los ntawm cov khoom noj thiab muab tso rau hauv qhov chaw raug xaiv ntawm lub rooj tsav xwm luam tawm (PCB). Kev ua haujlwm ntawm lub tshuab tuaj tos thiab qhov chaw feem ntau suav nrog cov kauj ruam hauv qab no:
1. PCB Positioning: PCB tau muab tso rau hauv lub tshuab tuaj tos thiab tso lub tshuab los ntawm txoj siv conveyor, thiab qhov chaw kho qhov muag (xws li lub koob yees duab CCD) txheeb xyuas cov ntsiab lus siv ntawm PCB kom paub tseeb qhov tseeb (qhov yuam kev yog feem ntau tswj tsis pub dhau ± 0.05mm).
2. Pickup Cheebtsam: Tus tuaj tos thiab tso lub taub hau khaws cov khoom los ntawm lub feeder (xws li reel, tais, los yog raj). Lub tshuab nqus tsev siab ntawm lub nozzle feem ntau yog -60kPa rau -80kPa kom ruaj khov tivthaiv adsorption.
3. Kev tshuaj xyuas thiab kho cov khoom: Lub polarity, qhov loj me, thiab txoj hauj lwm ntawm cov khoom raug tshuaj xyuas siv lub zeem muag, thiab kev kho lub kaum sab xis yog ua thaum tsim nyog (kev sib hloov qhov tseeb tuaj yeem ncav cuag ± 0.1 degree).
4. Muab tso rau: Precisely muab cov khoom rau ntawm PCB pads. Qhov chaw ceev nws txawv nyob ntawm tus qauv; siab -kev xaiv ceev-thiab- qhov chaw tshuab tuaj yeem ncav cuag 30,000-60,000 ntsiab lus hauv ib teev. Cov thev naus laus zis tseem ceeb ntawm kev xaiv-thiab- qhov chaw tshuab suav nrog kev tswj hwm kev ua haujlwm siab, kev pom kev zoo, thiab kev sib koom ua ke pub noj. Lawv tau siv dav hauv cov khoom siv hluav taws xob, khoom siv hluav taws xob hauv tsheb, thiab cov khoom siv sib txuas lus.
