# Industrial Specification: Dispenser Unit

## 1. Technical Definition
Precision dispensing component for applying adhesives or epoxies in semiconductor die attachment

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15.0 bar at 23°C with 0.1 bar resolution**. Failure boundary: **18.5 bar internal pressure causing diaphragm rupture or 0.3 bar causing insufficient flow for 0.1 mm³/s dispensing**, Mechanism: **Diaphragm material (316L stainless steel) yield strength of 205 MPa exceeded at 18.5 bar, or laminar flow disruption below Reynolds number 2000 causing inconsistent adhesive deposition**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
