# Industrial Specification: Nozzle Changer

## 1. Technical Definition
An automated mechanism within an SMT pick-and-place machine that exchanges vacuum nozzles to handle different electronic components.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.3-0.8 bar vacuum pressure, 0.1-0.5 mm nozzle tip positioning accuracy, 0.5-2.0 seconds exchange cycle time**. Failure boundary: **Vacuum pressure below 0.2 bar causes component drop, nozzle tip wear exceeding 0.05 mm radius deviation causes misalignment, exchange cycle exceeding 3.0 seconds triggers machine timeout**, Mechanism: **Venturi effect vacuum generation failure due to compressed air pressure drop below 4.0 bar, nozzle tip abrasive wear from ceramic component contact at &gt;100,000 cycles, pneumatic cylinder stiction at &lt;15% relative humidity causing seal friction coefficient &gt;0.3**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
