# Industrial Specification: Processor Board

## 1. Technical Definition
A printed circuit board containing the central processing unit and supporting components for control systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-85°C ambient temperature, 4.75-5.25V DC supply voltage, 0-100% relative humidity (non-condensing)**. Failure boundary: **Junction temperature exceeding 125°C for silicon-based CPUs, voltage transients exceeding ±15% of nominal for &gt;10ms, sustained humidity &gt;85% RH with condensation**, Mechanism: **Thermal runaway due to Arrhenius equation acceleration of electromigration (failure rate doubles per 10°C rise above 85°C), dielectric breakdown at electric field strengths &gt;10 MV/m in SiO₂ layers, electrochemical migration at &gt;0.6V potential difference in humid environments**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$
