Applications and Advantages of AOI and X-RAY in SMT Production ????

In the realm of Surface Mount Technology (SMT) production, both Automated Optical Inspection (AOI) and X-RAY play invaluable roles. Here’s a dive into their principles and advantages. ????

AOI: Principles and Benefits

Automated Optical Inspection (AOI) is a cutting-edge technology increasingly used in modern manufacturing. AOI relies on optical principles and RGB lights to detect common defects during soldering.

Principles

1. Optical Calculation: Scans the surface using light reflection and generates an image. ??
2. Appearance Comparison: Detects defects such as missing parts, incorrect orientation, misalignment, and poor soldering. ???

Advantages

• High Efficiency: Real-time detection, ideal for mass production. ??
• High Precision: Detects even minute errors. ??
• Ease of Use: User-friendly with a gentle learning curve. ??

X-RAY: Principles and Industry Benefits

X-RAY inspection allows scanning internal structures without damaging the object, suitable for complex items like BGAs.

Principles

1. X-ray Source: Generates X-rays by high-voltage electrons hitting a metal target and forms an image by penetrating the product. ??
2. Image Analysis: Different materials absorb X-rays at different rates, creating images with varying brightness levels to detect internal defects. ???

Advantages

• Non-Destructive: Detects internal defects without damaging the product. ???
• High Depth: Capable of inspecting internal defects. ??
• Wide Application: Suitable for complex structures and materials like lithium batteries and IC chips. ??
