HAST high temperature and high pressure test chamber

HAST high temperature and high pressure test chamberThe highly accelerated life test chamber is an industrial equipment that accelerates the aging process of products by simulating high temperature, high humidity, and high pressure environments. It is mainly used to evaluate the reliability and durability of electronic components, semiconductors, PCB boards, photovoltaic modules, and other products. The following is a detailed introduction to its core features, application areas, and technical parameters:

1、 Core Features

Accelerated aging test

By simultaneously applying high temperature (usually 105 ℃~155 ℃), high humidity (65%~100% RH), and high pressure (0.2~3.5kg/cm ²) environmental stress, the natural aging process of several years is compressed to a few days, significantly reducing

Short R&D cycle.

For example, the traditional 85 ℃/85% RH/1000 hour test can be completed by the HAST test chamber within 130 ℃/85% RH/96 hours, with an efficiency increase of more than 10 times.

Precise environmental control

Using PID temperature control module, the temperature fluctuation range is ± 0.5 ℃, and the humidity fluctuation is ± 2.5% RH, ensuring stable test conditions.

Support switching between saturated (100% RH) and unsaturated (such as 75% RH) modes to meet different testing requirements.

Security protection design

Equipped with multiple protection devices such as mechanical pressure safety valves, emergency relief valves, and reverse pressure door locks to prevent accidents caused by equipment failure or misoperation, including overheating, overpressure, water shortage, and overload.

Compliant with international standards such as ASME BPVC and IEC60068-2-66 to ensure testing compliance.

Intelligent operation and data management

7-inch true color touch screen controller, supports 250 sets of programs, 12500 segments of programming, and can store a large amount of test data.

Provide USB curve download and RS-485 communication interface for easy data export and analysis.

Modularization and Customization

The inner liner is designed with circular stainless steel to prevent condensation and dripping, protecting the sample from direct impact of steam.

The double-layer stainless steel sample holder can be customized and supports expansion to 55 bias terminals (AC/DC 125V 1A) to meet different sample sizes and testing needs.

2、 Application Fields

Electronic components

Test the sealing, moisture absorption, and aging performance of IC packaging, connectors, circuit boards, etc. in high temperature and high humidity environments to detect defects such as water leakage and delamination in advance.

automotive industry

Evaluate the stability of onboard electronics (such as sensors and instrument panels) in the environment to ensure the safety and reliability of the vehicle.

aerospace

Simulate the working state of aircraft electronic equipment under high pressure and high humidity conditions to verify its performance stability.

New energy and photovoltaics

Test the high-voltage wet heat aging performance of photovoltaic modules (such as EVA film) and magnetic materials to optimize product lifespan.
