Environmental Stress Screening ESS Test Chamber

Name: Environmental Stress Screening ESS Test Chamber
Brand: Xi'an LIB Environmental Simulation Industry

Environmental Stress Screening ess test chambers are specifically designed for environmental stress screening of electronic components, complete units, and other high-reliability products (wide temperature range: -70/-40/-20°C to +150°C). By inducing rapid temperature changes (20°C/min), they expose potential defects within a short timeframe, enhancing product reliability and stability.

It achieves rapid temperature changes far exceeding the 1–3°C/min rate of traditional constant temperature and humidity chamber. Rapid cooling subjects products to more severe thermal stress during expansion and contraction, effectively screening for potential issues such as solder joint defects, material fatigue, and connector failures.、

Standard Models For You: TR5-100, TR5-225, TR5-500, TR5-800, TR5-1000 and more customized models.

Applicable Standards: AAMA501, ASTM D4169-16, IEC 61215, IEC 61646, IEC61108, IEC62688, MIL-STD-811D

Environmental Stress Screening ESS Test Chamber Features and Benefits

1. Rapid Temperature Change Capability

Achieves heating/cooling rates of up to 15–30°C/min, significantly exceeding standard environmental test chambers. This enables swift identification of potential product defects and enhances testing efficiency.

2. Multi-Stress Combination Capabilities

Beyond temperature cycling, optional features like humidity, vibration, and electromagnetic interference enable combined environmental stress testing to meet stringent reliability verification requirements.

3. Wide Temperature Range for Diverse Applications

Supports multiple starting points (-70/-40/-20°C to +150°C) to meet various testing requirements for electronics, aerospace, automotive, and other high-reliability industries.

4. Modular and Customizable Design

Non-standard customization is available based on product dimensions, test conditions, and interface requirements—such as adding monitoring windows or data acquisition interfaces.
