The extremely accelerated stress environment is defined by high temperature, high humidity and high pressure. WEIBER provides humidity resistance evaluation test for electronics components through customized Extremely Accelerated Stress Test Chamber. This chamber provides high performance test in minimal amount of time according to international IEC 60068-2-66 standard. This chamber also known as Accelerated Stress Test Chamber, Halt and Hass Test Chamber, Halt Test Chamber and Hass Test Chamber.

 

This chamber reduces the time taken for humidity testing in electronic components. 2 types of tests saturated and unsaturated extremely accelerated stress test can be performed. In saturated test the temperature is maintained at 1210C at 100%RH, and for unsaturated temperature of 110, 120, 1300C is maintained at 85%RH. Normally for electronic components unsaturated type test is done.

 

Standards:

  • IEC 60068-2-66
  • EIA/JEDEC Test Method A110 & 102C

Weiber provides Agree Test Chambers to test the equipments for their adaptability to changing temperature, humidity and vibrations. During transportation the component is exposed to vibration motion, change in temperature and humidity. Using Agree test chamber the withstand strength of components can be determined.

Agree test chamber are designed to perform specific temperature, humidity and vibration test to improve the quality and reliability of components. The Agree method of testing is an acronym for the Department of Defence Advisory Group Reliability of Electronics Equipments. This chamber also known as Temperature Humidity Vibration Test chamber and Stress Test Chamber


Chamber floor are designed to be changeable to accommodate different “floor plugs” for vibration systemsWIEBER provides customised Agree Test Chambers with advanced features.

HALT and HASS chambers from WEIBER provide extreme temperature & vibration capabilities used during the product design and manufacturing cycles to compress the time normally required to identify design and process weaknesses. HALT techniques are important in uncovering many of the weak links inherent to the design and fabrication process of a new product. HASS techniques are incorporated during the production phase to find manufacturing process defects that could cause product failures in the field.

 

Features:

  • High temperature ramp rates at 60°C (194°F) per minute: for increased thermal stresses to speed precipitation.
  • Cooling unit comprises of LN2 system.
  • Pressure gauges: allow operating pressures to be continuously monitored.
  • Large dynamic range shaker: 1  to 60 GRMS with a bare table. High GRMS levels are used to enhance precipitation and low level with Modulated Excitation are used to increase detection.
  • Lowest noise level: 72 dBA at 30 GRMS.
  • One size chamber can accommodate wide range of product weights/sizes for high payload weights using replaceable springs.
  • Safety Stop Mode Automatic Purge and Reset: Protects operators, products, and equipment
  • Oxygen Monitor and Alarm: Interfaced to chamber LN2 system to ensure safe oxygen levels
  • Door Interlocks with Programmable Features: Prevents door openings during operation, protecting operators
  • High Volume Air Circulation System
  • Air Distribution Through Adjustable Ducts or Slot: Optimizes configurable and adjustable airflow to the products
  • Vibration table: perform 3 mode of vibration(single axis, double axis, triple axis)
  • Displacement Levels: 3 times more displacement with dual strike impactors than conventional systems
  • Color touch panel.
  • HMI+PLC in one unit
  • PCRC sheet body-Powder coated steel body assures corrosion resistant chamber and allows working of chamber at high temperature applications.
  • Pre-attached data logger with data analysis software-Primary benefits of using data loggers is to automatically collect data 24-hour basis.Graph and table format of results can be produced automatically by the data logging software.
  • Aesthetically designed-Designed according to the standards and principles underlining industry’s aesthetic values.
  • Corrosion Resistant interior and exteriors-Corrosion resistant coatings like epoxy coatings are applied inside and outside the chamber to prevent against degradation due to moisture, salt spray, oxidation or exposure to a variety of environmental or industrial chemicals/ corrosive agents.
  • Sturdy Construction- WEIBER chambers are built with robustness to withstand stress and strain, giving the chamber long life and ability to perform in extreme stress environments.

 

Operating Principle:

The Halt Profile (Highly Accelerated Life Test):

HALT is a step stress process performed during the product’s prototype phase that determines a product’s operating limits, identifies design weaknesses, and identifies weak components. The prototype phase is the fastest and least expensive point to make improvements.

In the HALT process, the test sample is subjected to progressively higher stress levels. Thermal dwells, rapid temperature transitions, vibration, and a combination of temperature and vibration are employed to precipitate latent, inherent defects in the design, at the component level, or in the manufacturing process.
