The Stratus III is our manual solution to automated inspection of most kinds of products. Defect types range from excess paste, missing paste, smearing, narrowing, mouse bites, holes, via covering, sprayers, bleeding of paste, contamination, layer shifts, substrate shrinking, screen aging, etc.
The materials that are inspected are usually conductor materials (like silver or silver palladium), resistor paste, cover glass, adhesives, gold, etc., and it detects all defects that are relevant in modern fine line screen printing or thin film applications. The tendency goes to ever finer structures. On prints with less than 50 µm line widths, inspection with the human eye is not possible or very unreliable. In Thin Film applications the strain and difficulty of inspection has m ade automated inspection solutions a basic requirement. The STRATUS VISION AOI systems can inspect a 10” x 10” substrate in less than 10 seconds and find defects between 0.2µm and 30µm (depends on pixel size).
