On sib xyaw ua ke, PCB cov laug cam, xov tooj ntawm tes thiab cov cim kev lag luam ntawm micron yooj yim thiab ib puag ncig cov pa phem tshwm sim los ntawm cov num luam yeeb ib txwm muaj.
Tshwj xeeb tshaj yog haum rau nti traceagility tswj, los ntawm laser codycing lub neej cov ntaub ntawv kom tau raws li cov khoom lag luam kom tiav ntawm kev lag luam 4. {1}}.
Piv nrog tshuab engraving, laser ua tau zoo tau nce ntau tshaj 3 zaug, thiab tsis muaj kev siv tus nqi ntev yog txo los ntawm 60%.
