# Industrial Specification: Surface Plate

## 1. Technical Definition
The flat, heated contact surface of a heated platen that directly interfaces with materials during processing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-350°C with ±2°C uniformity across surface, 0.5-3.0 MPa contact pressure**. Failure boundary: **Thermal gradient exceeding 15°C/cm across plate surface, surface flatness deviation &gt;0.02 mm/m², temperature overshoot beyond 400°C**, Mechanism: **Thermal expansion coefficient mismatch (α_plate=11×10⁻⁶/°C vs α_material=23×10⁻⁶/°C) causing differential expansion stresses exceeding yield strength of 250 MPa**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| PID controller integral windup during rapid temperature setpoint changes | 8 | Surface temperature overshoot to 420°C causing material degradation and plate warping | Implement anti-windup compensation with 0.1-10.0 second reset time and rate limiting at 5°C/minute |
| Cyclic thermal loading at 0.1 Hz frequency from batch processing | 8 | Thermal fatigue cracking initiating at heater element boundaries after 10⁵ cycles | Finite element analysis-optimized heater pattern with stress-relief grooves and Inconel 718 cladding (σ_y=1100 MPa at 350°C) |
