 Mouse: Controls the location of the ROI template. Use the mouse to align the ROI to the

component centroid location.

 Arrow Keys: Control both ROI and Centroid movement as a group. Use the <Arrow Keys> to

position both the ROI (search zone) and centroid reference to the Device center.

 Ctrl Key + Arrow Keys: Control the size (expand/reduce) of the ROI area

APPLICATION NOTE: If you are unsure which is the active ROI, check the Device’s Device

Outline by selecting it from the Device menu, <Move/ Device Outline>.

4. While verifying Device placement, an Offset Menu can be accessed right-clicking the mouse pointer

inside the <Confirm/Adjust Device Position> dialog box. The <Offset Device Position> selection in

the menu applies the Device centroid position offset a user made using the arrow keys) to all the

Devices with the same Device number waiting to be placed. This is useful to correct problem XY data

where pin 1 position of an IC is mistakenly given as its centroid position. The <Rotate Device 90>

selection is to correct the rotation problem of the XY data by rotating the Device. This menu selection

can be used multiple times to achieve correct rotation. I.e. use it twice to rotate 180°. Although these

two menu selections provide a convenient way to correct XY data problem on the fly, it mean to be

used scarcely. In most cases, it is better to correct the problem at the source by correcting the XY data

itself before the import process.

5. For faster device training make sure you have the <Auto Train> Check Box <ON> checked in the

Confirm/Adjust Device Location Prompt Window. Using Auto Train common devices are taught

once and all matching devices are automatically added a library. The training process continues

automatically (unattended), stopping only if the expected device is not found or the Device is not in the

Device Library and must be interactively defined by the operator.
