In-Sight 2800 Series
Easy-to-use vision system with pre-trained AI for solving basic to intermediate-level processing tasks.
Why advanced OCR matters for integrated circuits
After completing package testing, integrated circuits (ICs) are marked with identification codes that include manufacturer details and technical specifications. Accurate Optical Character Recognition (OCR) reading of these tiny, laser-marked or etched characters is critical for end-to-end traceability and correct component usage. It also supports anti-counterfeiting efforts by verifying chip authenticity, and ensures audit-ready data, making identity information accessible for downstream users such as system design houses, PCB assembly companies, and quality and compliance teams.
AI-enabled OCR enhances this capability by reliably reading any type of code—regardless of its condition—and integrating seamlessly into manufacturing and quality control workflows.
Overcoming code reading challenges with OCR technology
The increasing complexity and variability of modern IC markings can challenge traditional machine vision, making reliable identification and verification difficult. Technicians often rely on visual inspection or microscopes – a process that can be slow, error-prone, and inconsistent.
Key challenges that require advanced OCR algorithms include:
- Tiny, variable text laser-marked or chemically etched on ICs
- Distortion caused by textured or uneven surfaces
- Low-contrast or poorly etched characters
- Curved or skewed text on glossy or irregular surfaces
- Variations in print quality across chips
Cognex AI-powered OCR tools use advanced pre-trained libraries to read and verify even the most challenging IC codes. With built-in adaptability for new or unique characters these tools enable fast, automated, and highly accurate verification.
Cognex AI makes it easy to read challenging, low-contrast text on PCB components.
