| Abstract: | By comparing the method of step-and-repeat scanning with the one of hexagonal seamless scanning,which are favorably used in the laser projection imaging for printed circuit board(PCB),it is shown that the hexagonal seamless scan-repeat technology is of more superiority.It is expounded the process of uniform exposure in hexagonal seamless scan- repeat technology as well as the principle to achieve it.It is also analyzed the factors to affect scanning imaging such as exposure dose,velocity and so on. |
