Product Specifications

Technical details and manufacturing context for Pattern Recognition System (PRS)

Definition
The Pattern Recognition System (PRS) is a critical component of a Wire Bonder that uses computer vision and image processing algorithms to locate, identify, and precisely align the bonding pads on semiconductor chips or packages. It ensures the bonding tool (capillary) is positioned with micron-level accuracy for reliable wire connections.
Working Principle
The system captures a high-resolution image of the target area (e.g., a chip). It then processes this image using pattern matching or feature extraction algorithms to compare it against a stored reference template. Based on the calculated offset, it sends correction coordinates to the wire bonder's motion control system to align the bonding head precisely over the target pad.
