Lead Ringer Overview

1. The Lead Ringer algorithm is designed to enable multi-leaded devices inspection (see Figure below), to check if

the leads of the component are correctly placed and soldered, and to detect bent or lifted leads.

2. It can be used alone, or alongside the other joint inspection methods.

3. This algo allows the user to compare boxes usually placed on the lead/solder against a fixed/relative threshold.

Lead Ringer - Requirement

129

1. Users need to turn off any unwanted test during the setup time. (e.g. joint, bridge, side fillet)

2. Setup of the Ringer algorithm must be done on a known good component.

3. User must ensure the presence/absence inspection algorithm setup correctly.

• Ringer algorithm will not activated if component detected as not present.

4. Must Setup the search area correctly.

• Restricted exactly on the area for the component (Including leads & Pads) as follow:
