Step2: The dialog shown in Figure 1-5 appears. Register the PCB color as NG color.

Procedures depend on the presence or absence of bare PCB.

Figure 1-5 Specify PCB Color

1.2.1 With Bare PCB

Extracts a PCB color from a bare PCB and register it as an NG color.

NOTE

In the case of using KPK for post-reﬂ ow inspection, it is recommended to use a bare

PCB after reﬂ ow-oven. That is able to reduce color variation caused by ﬂ ux and to

extract PCB color properly.

Step1: Press Switch Images.

Step2: If bare PCBs are already scanned and saved, select the ﬁ le from the SERIES Image list-

box, and press Load SERIES Image. If no series image is saved, procedures depend on

machine type benchtop machine, inline machine or BF-Editor.

NOTE

Series image indicates series of inspection images stored in the SERIES folder

under a board name folder.

In case of benchtop machines

Load the PCB to the machine and press Scan.

In case of inline machines

Adjust conveyor rail width and set the PCB on conveyor rail. Press Load / Unload.

Set the PCB in the machine and press Scan. To unload the PCB, press Load / Unload.

In case of BF-Editor

Press Load Image and select TOPLIGHT.BMP saved in arbitrary folder.

(e.g., D:\BF1\BF1DATA\Inspection Group Name\PCB Name folder)

Step3: Press Extract Colors Automatically from Bare Board Image in Figure 1-6.

The dialog shown in Figure 1-8 appears.

Step4: Adjust the window size to extract component color by moving a slide-bar. The window size

is area to extract PCB color. Press OK and start PCB color extraction.

NOTE

The speciﬁ ed window size is common to all components data. Therefore make the

window size in accordance with the minimum component size.

NOTE

No need for Detailed settings.

Step5: Make sure that the PCB color is displayed in black. The closer the PCB color is to the

extracted PCB color, the darker it displays. Refer to 1.2.3 Auto Deployment of KPK.
