# Industrial Specification: Automated Optical Inspection System

## 1. Technical Definition
A vision-based inspection system that automatically detects defects in surface-mount components and solder joints on printed circuit boards.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 m focal distance, 10-1000 lux illumination, 20-40°C ambient temperature**. Failure boundary: **Lens distortion exceeding 0.05% pincushion/barrel distortion, CCD sensor temperature exceeding 60°C, illumination uniformity below 85%**, Mechanism: **Thermal expansion mismatch between lens glass (CTE 7.1×10⁻⁶/K) and aluminum housing (CTE 23.1×10⁻⁶/K) causing focal plane shift; photodiode quantum efficiency degradation above 60°C due to increased dark current (doubling every 8-10°C rise)**.

### 2.1 Analytical Physics Model
Governed by the **Rayleigh Resolution Criterion**:

> **Primary Equation**: $d = \frac{0.61 \lambda}{NA}$  
> **Engineering Impact**: Defines the theoretical limit of machine vision systems.
