SCREENED PASTE
Process Control and Inspection of Screened Paste, ITO, and Glass Masks

The Mscan can be configured for high speed inspection of devices using transmitted and reflected illumination simultaneously. The flexible architecture of the Beltronics processor, as described in the Mscan Highlights Section, enables the system to tolerate normal process variation due to spatial expansion, shrinkage and past smear. Figure 23 is the reflected light image of a screened circuit. Figure 24 shows the partial open defect found by the Mscan.
