Integrated Circuit Edge Damage Detection System

Project Background and Design Goal

Boston Scientific’s Cardiac Rhythm Management (CRM) division electrically tests the robustness of over 500,000 integrated circuits annually before installing them into medical devices. The goal of this project is to design and develop a prototype inspection system capable of reliably detecting edge damage on integrated circuits prior to assembly into finished medical devices.

Design Constraints

• Detect defect size bigger than or equal to 0.07 mm
• Save pictures of damaged ICs with defects highlighted
• Scan ICs repeatably after given user input to begin scanning
• Scanning one tray shall finish in under 1 hour
• Use off the shelf components
• Be able to fit on a 3 ft X 30 in table

Design Outcomes

The team designed an automated inspection system that uses an AI-enabled camera to identify edge damage on ICs. The system positions each IC, captures images, and highlights any detected damage. This solution is intended to reduce manual inspection time and improve consistency in defect detection.
