Board Definition

Chapter6. Board Definition

Used the ‘Board’ submenu to edit data for the placement of components on a PCB (Printed

Circuit Board).

Figure6.1 Sequence of executing board menu

6.1. Basic Setup

When the ‘Board’ submenu is selected, the following dialog box is displayed.

 <1. Customer Name> edit box

Enter the name of the customer who requested the PCB operation. Up to 64 characters

can be entered.

 <2. Board Name> edit box

Enter the PCB name. Up to 64 characters can be entered.

 <3. Coordinate> combo box

Select the PCB coordinate system. Available coordinate systems are as follows.

Left-Up: When the PCB flows from left to right based on the front side of the

machine.

Right-Up: When the PCB flows from right to left based on the front side of the

machine.

Left-Down: When the PCB flows from left to right based on the front side of the

machine.

Right-Down: When the PCB flows from right to left based on the rear side of

the machine.

 <4. Initial Theta>

Since it cannot be assumed that the PCB fed into the working area is completely

horizontal to the fixed frame of the conveyor, the user must set the initial angle (the

offset angle between the PCB and fixed frame) when making a PCB program.

If the PCB program was created with the PCB of the initially created PCB program

distorted by 1 degree, all the PCBs produced after this are worked on without

modifying the 1 degree distortion.

Therefore, teach two points at the same horizontal or vertical line on the PCB to

calculate the initial offset angle between the PCB and the fixed frame and create all

coordinates for placement.

Used to obtain CAD information on PCB fiducial by feeding the PCB into the

machine and teaching the PCB fiducial accurately when CAD data is unavailable.

Since this value is used no longer after the CAD data on the PCB fiducial is obtained,

it is initialized to ‘0’ at the time that the corresponding PCB is transferred out. Once

compensated, the offset angle is reflected automatically. Therefore, it is not needed to

compensate the offset each time.
