By default each new device trained is given an ideal score of 700. Components that pass test at the 700

setting are exceptional clear, well-labeled, devices with good contrast and excellent solder characteristics;

most devices do not fit this criterion and therefore must be adjusted or fine-tuned.

NOTE: Adjusting threshold settings should only be performed if you already have trained a few templates and

reviewed and corrected any poorly defined templates. Poorly created templates should always be deleted and

replaced with improved versions. See: How to Fix Bad Templates

1. Right-click on the device outline. This will open a Device Editor Menu. Select <Edit Device> to inspect

the “Part Parameter” and verify that the settings are correct.

a. Pass Scores: Proper pass score setting vary from device-to-device.

b. A typical range for Pass setting can be between 600 – 700; but since few assemblies meet this

criterion, it is likely that this setting will require adjustment.

2. Reduce the Pass Score setting within the range stated for that device. NOTE: Adjustments should be

made in small 25-50 point increments.

3. Other setting in the Basic and Extended Parameters menus can be ignored at this time as many

settings may not apply to a specific device and others are for advanced uses and require additional

specialized training.
