Geometric Pattern Matching Software for Die and Wire Bonding
VisionPilot® utilizes advanced geometric pattern matching technology to reliably and accurately locate parts. Even under the most challenging conditions, this exclusive Palomar Technologies software can significantly reduce or eliminate fixturing requirements and cost. For locating parts or features, VisionPilot provides the maximum inspection yield and reliability available in a vision system. VisionPilot is available for die and wire bond.
VisionPilot for Die Bond
From learned reference points using Radar Referencing®, VisionPilot is able to locate a randomly oriented die from the first fiducial and subsequently finds the second fiducial based off that angle—for example, the above die was found at -45 degree angle.
VisionPilot for Wire Bond
Built upon and using elements from Cognex® Vision Engine's powerful PatMax® software, VisionPilot is designed for implementation across Palomar's suite of wire bonder platforms. VisionPilot is the unrivaled best-in-class vision technology for wire bonding.
Benefits of VisionPilot for Wire Bond:
- Finds images at +/- 180 degree compared to +/-7 degree for auto correlation
- Less light sensitive
- Less light sensitive to part variations
- Radar Referencing theoretical pixel accuracy is 1/40 vs 1/10 for auto correlation
This is a typical example of a flat round horizontal pin fiducial and how Radar Referencing zone parameters are set to accommodate different package/pin suppliers with different pin widths. Standard Algorithm (Autocorrelation) would not accommodate the pin width variations and pin imperfections.
