Summary

A HAST chamber in the USA can help accelerate the testing process of various types of manufacturers, such as semiconductors, PCBs, LEDs, and other electronic components, by subjecting their products to high temperatures, humidity, and pressure. This article covers the functioning of a HAST test chamber, some of its common uses, HAST test chamber specifications, factors affecting HAST chamber price and HAST chamber cost, and the selection of a good HAST chamber manufacturer or HAST chamber supplier.

Introduction 

Electronics are shrinking, more powerful, and more complicated than ever. At the same time, it is essential to ensure reliability within a much shorter development cycle. Conventional environmental testing is a long process and might take several weeks or months; therefore, accelerated reliability testing is becoming more relevant in today’s electronics industry.

The HAST chamber in the USA, also called a highly accelerated stress test chamber or highly accelerated stress testing chamber, simulates high temperatures, high humidity, and high pressure to accelerate degradation processes. In that way, the manufacturer may find out about any flaws in product design prior to its release into production using an accelerated stress test chamber.

Testron Group offers systems like the TT-3545 and TT-5565 HAST chamber cabinet models for semiconductor, IC packaging, microelectronics, PCB, and other reliability tests with complete HAST chamber testing equipment.

What is a HAST test chamber?

The HAST test chamber is an advanced version of the environmental test chamber, where temperature, humidity, and pressure are combined to accelerate the stresses from the environment onto the test specimen.

Unlike an environmental test chamber, the HAST testing chamber works under high-pressure conditions and is very useful in cases where engineers want to accelerate moisture stress-induced failure.

A HAST testing chamber is used to detect the following:

• Moisture Ingress
• Corrosion and Oxidation
• Degradation of Electrical Insulation
• Weaknesses in Solder and Interconnects
• Defects in Encapsulation
• Failure of Seals and Packaging

Therefore, HAST chamber testing equipment is very useful for product development and production quality programs.

Why is a HAST environmental test chamber necessary for semiconductor and electronics testing?

Moisture and heat exposure are serious threats to the reliability of semiconductors and electronics. In a HAST environmental chamber, users can accelerate the above factors in a laboratory setting.

1. Reliability Testing of Semiconductors

A HAST chamber in the USA can be utilized for testing semiconductor packages, integrated circuits, microelectronic devices, etc.

2. Testing of PCB

PCB manufacturers have a chance to evaluate moisture resistance, electrical insulation, solder joints, and other possible failure modes using a HAST test chamber.

3. Reliability Testing of LEDs

LEDs and their packages are subjected to high heat and humidity during their lifetime. In a highly accelerated stress testing chamber, users can evaluate the environmental stress resistance of LED packages.

4. Electronic Component Testing

Electronic connectors, sensors, packaged components, and other electronic devices can be tested in an accelerated stress test chamber before mass production.

Important Applications of the HAST Chamber in the USA

Some important applications of the HAST test chamber include:

1. Reliability testing of semiconductor and integrated circuits
2. Testing of PCBs and other electronics assemblies
3. Evaluation of IC packaging
4. Testing of LED components
5. Moisture ingress testing
6. Evaluation of seal and encapsulation
7. Product failure detection and acceleration
8. Testing for R&D purposes
9. Validation of production reliability

An industrial HAST chamber in the USA can be useful for laboratories undertaking multiple reliability programs.

Choosing the Best HAST Chamber Manufacturer in the USA

Selecting the appropriate HAST chamber supplier goes beyond price comparison. It is crucial to assess the capabilities of the chamber and see if it will suit your needs.

Ranges of Temperature, Humidity, and Pressure

Prior to buying a HAST chamber in the USA, make sure that the chamber is capable of meeting the environmental conditions necessary for your testing. Here is what the Testron TT-3545 HAST Chamber has to offer:

• Temperature range: +105°C to +135°C 
• Humidity range: 65% RH to 100% RH
• Pressure range: 0.05 to 0.3 MPa

Chamber Capacity

Choose capacity depending on the size of your samples and the volume of tests to conduct. While the TT-3545 has a capacity of about 55 L, the TT-5565 has about 150 L.

Control and Data Logging Facilities

Your HAST chamber cabinet needs to have facilities for programming tests, monitoring, data logging, and alarms. The Testron chambers have features such as touchscreen control, program cycle, graphic data display, and RS-485 communication.

Safety Facilities

HAST testing entails the use of pressure and high temperatures. Therefore, safety is crucial in your choice of HAST chambers. Look for pressure relief facilities, over-temperature facilities, door interlocks, water-level facilities, and fault alarms.

HAST Chamber Validation – Points to Consider

The HAST chamber validation becomes a necessity for those laboratories that need accurate and reliable test data.

The following aspects may be considered before conducting tests:

• Temperature uniformity and stability
• Humidity performance
• Pressure accuracy
• Sensor calibration
• Controller operation
• Safety interlocks
• Data logging capability
• Test cycle repeatability

An authorized HAST chamber supplier must also provide documentation and support for installation, commissioning, calibration, and maintenance.

HAST Chamber Cost and Price Determining Factors

One of the most frequent purchasing inquiries is how much a HAST chamber costs.

The HAST chamber cost will depend on the chamber volume, pressure, temperature and humidity ranges, materials used for the chamber building, controller, safety devices, and additional options.

Key determining factors in HAST chamber cost calculation are the following:

• Chamber volume
• Pressure level
• Saturated or unsaturated humidity usage
• Stainless steel chamber construction
• Controller functionality and logging capabilities
• Validation and calibration needs
• Customized engineering solutions

Thus, the potential buyer must evaluate not only the purchase price but also the total value of the HAST chamber testing device.

TT-3545 HAST Chamber VS. TT-5565 HAST Chamber

There are two types of HAST testing device offered by Testron suitable for different testing conditions.

TT-5565 is used when there is a requirement for handling bigger testing loads, whereas TT-3545 is suitable for smaller labs due to its compact size.

Why Select Testron Group as a HAST Chamber Supplier?

Finding a suitable HAST chamber supplier is vital for ensuring efficient performance of tests in the future. Testron Group HAST chambers have a number of characteristics, including SUS316 interior steel, programming capability, data recording, pressure and temperature protection, and interlocks for safe operation. In addition, Testron claims that its HAST chambers meet IEC 60068 and GB/T standards.

Testron can even customize HAST chamber in the USA for special testing purposes.

Consult our Testron technical experts about your sample size and testing requirements, including test standards and reliability goals. 

HAST Chamber vs. Ordinary Environmental Chamber

Ordinary environmental test chamber tests are usually performed in controlled humidity and temperature conditions. In a heat test chamber, additional pressure is included, making it highly hostile.

In essence, a hast environmental test chamber becomes very important when there is a need to perform accelerated moisture and environmental stress tests.

For companies running a full-fledged materials and electronics lab, HAST devices can be coupled with other testing devices like material testing machines, environmental chambers, thermal shock chambers, etc.

1. Product or component to be tested
2. Temperature requirement
3. Humidity requirement
4. Pressure requirement
5. Sample size and quantity
6. Chamber capacity requirement
