Starting new serial No

Same with the description of new creation of PCB model of connecting module.

 Skip mark setting

This option is used when inspection o specific module is not desired among connecting

modules. For this, display marking at certain position inside the module, and it is possible only

for base module.

Add, move, delete

Move robot to random position in a module, and click <Add> button in „inspection skip

mark‟ screen to draw window position in which marking will be displayed. For reduction of

inspection time, around compensation mark is recommended for marking position.

Light setting

Users can set light to get clearer image.

Interested area

Set inspection condition in area based on white pixel or black pixel

Parameter

If „current white ratio‟ value that changes whenever „binarization level‟ value is adjusted is

lower than „SKIP (white ratio<)‟ value, the relevant module will skip inspection.

 Compensation mark setting

Check at „board mark setting‟.

 Coordinate compensation (module compensation mark)

This function is used to re-adjust position of compensation mark of each module.

Setting of „manual compensation mark‟

Move to module desired to be modified, and execute „coordinate compensation (module

compensation mark)‟ menu to set „manual compensation mark‟.

Move compensation mark of „compensation mark 1‟ like the saved image to correct offset

position. correct offset position for „compensation mark 2‟ with method.

 Coordinate compensation (component)

If position move degree of inspection windows between frames of the relevant module is

different, use this to compensate window position move to diagonal direction. Generally, this is

used after machine copy for PCB model sharing between machines.

[Figure 5-298 Use example of module coordinate compensation]

Check whether inspection window correctly matches with component in the center of frame of

the relevant module. If there is, move to the relevant frame. If not, select „all frame‟ in popup

menu displayed by clicking right button of the mouse in whole image screen, and then match

inspection window in the frame to component using „frame move‟ function.
