HAST High Pressure Test Chamber Accelerated Reliability Testing Solution

The Sailham HAST High Pressure Test Chamber is a professional environmental testing system designed for Highly Accelerated Stress Testing (HAST) of electronic components, semiconductor devices, printed circuit boards (PCBs), and moisture-sensitive materials. By combining high temperature, high humidity, and elevated pressure, the chamber creates a controlled accelerated stress environment to help evaluate product reliability and identify potential moisture-related defects.

As electronic products become smaller, more complex, and more widely used in demanding applications, manufacturers require reliable testing equipment to improve product quality and reduce failure risks. The Sailham HAST test chamber provides an effective solution for accelerated environmental reliability testing in electronics manufacturing, semiconductor packaging, PCB production, and laboratory research.

With a temperature range of +105°C to +143°C, a humidity range of 75% RH to 100% RH, and a pressure range of 1.2 to 2.89 kg/cm² (including 1 atm), this HAST high pressure test chamber supports a variety of demanding testing conditions. Its compact drum-type test chamber design provides a practical testing space for laboratory and industrial applications.

Key Advantages of Sailham HAST High Pressure Test Chamber

1. Wide Temperature Range for Accelerated Testing

The Sailham HAST chamber offers a temperature range from +105°C to +143°C, supporting high-temperature accelerated reliability testing. This range enables users to select suitable test conditions according to product characteristics and applicable testing procedures.

High-temperature and high-humidity exposure helps accelerate moisture-related stress mechanisms, making the equipment suitable for reliability evaluation of electronic components and semiconductor packages.

2. High Humidity and Pressure Control

The chamber supports a humidity range of 75% RH to 100% RH and a pressure range of 1.2 to 2.89 kg/cm², including atmospheric pressure. The combination of temperature, humidity, and pressure provides a controlled environment for evaluating moisture resistance and product reliability.

These testing conditions are particularly relevant to electronic components, PCB assemblies, IC packages, and other moisture-sensitive products.

3. Efficient Heating Performance

The HAST high pressure test chamber can heat from room temperature to +132°C at 85% RH in approximately 50 minutes.

This heating performance helps reduce the preparation time required for testing and supports more efficient laboratory workflows. For manufacturers conducting regular reliability testing, efficient heating can be beneficial in managing test schedules and improving equipment utilization.

4. Stable Temperature and Humidity Performance

The equipment is designed to maintain stable environmental conditions during testing.

Key performance specifications include:

• Temperature fluctuation: ±0.5°C

• Temperature uniformity: ±2°C

• Humidity fluctuation: ±3% RH

• Humidity uniformity: ±5% RH

These specifications support controlled testing conditions and help laboratories conduct repeatable environmental reliability evaluations.

5. Compact Drum-Type Chamber Design

The inner chamber features a drum-type structure with dimensions of Φ400 × D500 mm. This cylindrical testing space is suitable for small electronic components, semiconductor devices, PCB samples, and laboratory specimens.

The compact internal structure provides a practical solution for laboratories that require high-pressure accelerated testing without a large testing footprint.

Approximate external dimensions are W850 × H1650 × D1490 mm, making the chamber suitable for dedicated laboratory testing areas.

6. Support for Industry Testing Standards

The HAST high pressure test chamber is listed as conforming to JESDEC-A110 and IEC 60068-2-66-1994, among other standards.

These standards are relevant to accelerated temperature and humidity stress testing. Users should confirm the exact test method, operating conditions, and required compliance documentation according to their product testing specifications.
