Software speeds direct part mark identification
Billed as a breakthrough in Data Matrix code reading software, and based upon Cognex's patented PatMax technology, IDMax is designed for direct part mark identification.
Two new PatMax enhancements are now available on Cognex PC-based programmable vision systems.
PatMax XLC (extremely low contrast) improves the ability of PatMax to find barely visible objects or patterns in grainy or faint images, like those produced by powerful magnification techniques such as scanning electron microscopes (SEMs).
PatMax XLC improves wafer alignment for metrology tools, and minimises the need for expensive lighting and optics upgrades in order to analyse noisy, low-contrast images.
PatMax SA (scene alignment) provides partial-match alignment that eliminates the need for the entire pattern to be present in an image in order to obtain accurate results.
By enabling portions of the trained model to be outside the field of view, PatMax SA reduces manual operator intervention, increasing throughput in applications such as defect review stations.
"PatMax has become the most widely used software for semiconductor wafer alignment throughout the world, and we continue to invest in this technology which is so important to our customers", said Jim Hoffmaster, Chief Operating Officer for Cognex.
"These new enhancements, and other recent developments, such as PatInspect, Synthetic PatMax, and PatFlex, address our customers' most challenging alignment and inspection needs". Request a free brochure from Cognex UK ...
