Training New Boards

To start creating the board setup for a new board, select New Board from the

File menu. The load PCB dialog will display prompting the user to load a

board into the machine. A dialog appears to prompt user for the name

(assembly number) of the board.

From this dialog you also select the library mode for the new board training.

After pressing OK on the dialog, the process of defining the dimensions of the

board begins. In this process users are prompted to go to three corners of the

board. When users press the OK button on the prompt dialog, the system

records the position. . It is important to place the bottom left point and the

bottom right point in a straight line of the board. This two points defines the

base line where theta=0. So even if the board shape is irregular please try to

extrapolate a straight line for the bottom left corner and the bottom right

corner. The prompt dialog appears as:

After the board dimensioning is defined, the system will guide the user

through the process of defining alignment marks. The alignment marks (or

fiducials) are used by the system to compensate for board placement error

before the inspection begins. Two features on the board, one on the left and

one on the right, must be selected to serve as alignment marks. The left

alignment mark should be near bottom left or top left corner of the board. The

right alignment mark should be near the bottom right or top right corner of the

board. The left alignment mark MUST be to the left of the right alignment mark

for the system to align correctly.
