ESS Test Chamber Selection Guide: Linear vs. Non-linear

Views: 5     Author: Sanwood Technology     Publish Time: 2025-08-07      Origin: Sanwood Technology

Sanwood Technology's ESS Test Chamber is a device designed to simulate rapid temperature change environments. Its core feature is the ability to achieve high-speed heating or cooling, with temperature change rates typically ranging from 5°C to 25°C per minute. This process utilizes the expansion and contraction cycles caused by temperature differences in materials to accelerate material aging, detect product defects, or verify performance under extreme temperature conditions.

Equipment Parameters

Temperature range: -70°C to +180°C

Humidity range: 20%RH to 98%RH

Temperature fluctuation: ≤±0.5°C (unloaded, steady-state condition)

Temperature uniformity: ≤1.5°C (-40°C to 100°C) (unloaded, steady-state condition)

                                        ≤2.0℃ (100.1℃ to 180℃ or -70℃ to -40.1℃) (unloaded, steady state)

Temperature deviation: ≤±1.5℃ (-40℃ to +100℃) (unloaded, steady state)

                                      ≤±2.0°C (+100.1°C to +150°C or -70°C to -40.1°C) (no load, steady state)

Heating rate: -55°C to +155°C, (linear or non-linear: 5.0°C, 10.0°C, 15.0°C, 20.0°C, 25.0°C/min)

Cooling rate: +155°C to -55°C, (linear or non-linear: 5.0°C, 10.0°C, 15.0°C, 20.0°C, 25.0°C/min)


Application Areas

Electronics industry

IC chips, PCB boards: Testing solder joint cracking and material expansion coefficient compatibility under temperature cycling.

Semiconductor packaging: Evaluating the impact of rapid temperature changes on packaging structures.

Consumer electronics (mobile phones, computers): Simulating performance stability under extreme climatic conditions.

Automotive industry

In-vehicle electronics (ECUs, sensors): Verifying reliability under scenarios such as cold starts and high-temperature exposure.

Power batteries (EV batteries): Testing the impact of rapid temperature changes on battery lifespan.

Military and Aerospace

Avionics: Simulate the effects of rapid temperature changes at high altitudes on avionics equipment.

Missile/satellite components: Verify structural stability under extreme temperature shocks.

Military communication equipment: Test equipment reliability in battlefield environments.


Equipment Characteristics

Linear ESS Test Chamber

Characteristics: Constant temperature change rate (e.g., 5°C/min, 10°C/min), with temperature rising or falling linearly over time.

Advantages: Suitable for tests requiring stable, predictable temperature changes (e.g., material durability testing)

Non-Linear ESS Test Chamber

Characteristics: Variable temperature change rate (e.g., fast then slow, stepwise changes), simulating sudden changes or complex temperature fluctuations in real-world environments.

Advantages: More closely mimics sudden temperature conditions in real-world environments (e.g., day-night temperature differences, sudden changes during equipment startup/shutdown).
