S-type Algorithm - Side Fillets

1. Toe Logic

● OR Toe Fillet Check - Toe & Side in OR relation

● AND Toe Fillet Check - Toe & Side in AND relation

2. SF Logic

● Both Must Pass: Means that both side fillet boxes must pass in

order for the overall side fillet inspection to pass. This is the

default value.

● Combine Boxes: Means that the pixels in the two fillets are

combined and treated as a single side fillet box. One box can be

slightly below the SF Coverage Threshold if the other is exceeds

the SF Coverage Threshold by the same amount.

● One Must Pass: Means that the overall side fillet passes if

either side fillet box passes.

3. SF Size & SF Offset

● To adjust the sizes for SF ROI & offset for SF ROI.

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.
