Thaum qhov kev sib txuas ntawm cov txheej txheem ntug thiab PCB yog V-shaped zawj, qhov kev ncua deb ntawm cov ntug txheej ntawm lub cuab yeej thiab V-shaped zawj yog ≥2mm;thaum qhov kev sib txuas ntawm cov txheej txheem ntug thiab PCB yog lub qhov thwj, cov khoom siv thiab cov kab tsis raug tso cai los ntawm 2 hli nyob ib ncig ntawm lub thwj lub qhov.
○ Puzzle
Cov kev taw qhia ntawm lub jigsaw yuav tsum tau tsim thaum uas tig mus rau cov kev taw qhia ntawm lub conveying ntug.Thaum qhov loj me tsis tuaj yeem ua tau raws li qhov xav tau saum toj no rau qhov loj ntawm qhov kev txiav txim, qhov kev zam yog.Feem ntau yuav tsum tau "V-CUT" los yog tus naj npawb ntawm cov kab kos lub qhov ≤ 3 (tshwj tsis yog cov veneers slender), saib daim duab 3.4
Rau lub rooj tsavxwm tshwj xeeb, ua tib zoo saib xyuas kev sib txuas ntawm tus ntxhais lub rooj tsavxwm thiab lub rooj tsavxwm tus ntxhais, thiab sim ua kom muaj kev sib txuas ntawm txhua kauj ruam sib cais ntawm ib kab, raws li qhia hauv daim duab 3.5.
03 pcb puzzle saum kaum qhov teeb meem xav tau kev saib xyuas
Raws li ib txwm muaj, PCB ntau lawm yuav raug hu ua Panelization (Panelization) kev ua haujlwm, lub hom phiaj yog txhawm rau txhim kho kev ua haujlwm ntawm SMT cov kab ntau lawm, tom qab ntawd PCB PCB, peb yuav tsum them cov ntsiab lus dab tsi?Cia wb mus saib ua ke.
