Import CAD data

The process begins by the user selecting File | Import CAD File from the

main menu. The system opens the specified file to verify its format. If the

format is correct the system prompts the user to load a board corresponding

to the CAD data into the system.

The software analyzes the Device position information from the CAD data and

positions the Image over three Devices on the board. Each time, the user is

prompted to verify the Device position. The three Devices are a Device

closest to the bottom left corner followed by a Device closest to the bottom

right corner and then a Device closest to the top left corner of the board. Each

time a prompt dialog is displayed, the user should move the highlighted ROI

on the video window so that it is on top of the corresponding Device, and then

press OK on the prompt dialog. The prompt dialog is as follows:

When the OK button is pressed, the software records the Device position.

Based on the Device position of the three Devices located on the extreme

corners of the board, the ScanSpection system compensates for any

differences in the coordinate systems between the system that generated the

CAD data and the system reading it. The factors compensated are XY scaling

difference, board rotation, and XY axis skew.

After the coordinate system is adjusted, the system will move the Image to

view each Device one by one. If the Auto-Train is not enabled the user is

prompted by the above dialog on every Device to verify the Device's position

and size. The process is completed when all the Devices imported are

verified.

Based on the Device numbers supplied in the CAD data, the software adds

the newly imported Devices into the Device library after their templates are

trained.

The Device import process can be aborted at any time by pressing the Cancel

button on the Confirm/Adjust Device Position dialog or the Stop button on

the main button bar. The Devices that are imported up to this point will remain

in the Device list. To resume the import process, simply select Import CAD

File from the file menu again. Since the Device information in the CAD file

merges with the Device information in the board setup, there is no danger of

importing the same Device twice.

On the Confirm/Adjust Device Position dialog there is a check box, Auto
