Panels are required in order to save setup time and provide efficient usage of materials. So step & repeat of boards are created on one large panel. Thieving bars and venting patterns are added around the boards with Test coupons inserted in specific locations. Also Mounting holes, optical targets (fiducials) are added of various production machines. Text and logos are added for easy identification of the board.
