# Industrial Specification: Automated Surface-Mount Technology Assembly Line

## 1. Technical Definition
Integrated production system for automated placement and soldering of electronic components onto printed circuit boards.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-1.5 m/s conveyor speed, 20-30 μm placement accuracy, 235-260°C reflow temperature**. Failure boundary: **Placement accuracy &gt;50 μm, reflow temperature &lt;220°C or &gt;280°C, vacuum pressure &lt;60 kPa**, Mechanism: **Thermal expansion mismatch between PCB substrate (CTE 14-18 ppm/°C) and components (CTE 6-8 ppm/°C) causing solder joint fatigue; Bernoulli principle failure in vacuum nozzles below critical pressure threshold**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$
