100 Grms HALT/HASS Vibration System is New Technology Breakthrough

Share Article

Allegan, Michigan, (PR WEB) April 16, 2005 - Hanse Environmental, Inc. announces a new technological breakthrough with their new HALT/HASS vibration systems. The invention doubles the available six-degree-of-freedom (6DoF) vibration force from the general industry specification of 50 Grms to 100 Grms. This allows larger product loads to be tested for reliability and/or production screening while markedly reducing air consumption per Grms.

This invention, U.S. Patent Pending, will mean that manufactures of electronic products will be able to shorten time to market of new products and improve production throughput. Prior to this, Highly Accelerated Life tests (HALT) and Highly Accelerated Stress Screening (HASS) were limited by the weight of products tested. HALT is used by manufactures to develop reliable robust products. HASS is used in production to screen out early life defects.

The Hanse 6Dof Vibration system consists of a specially designed table with pneumatic actuators underneath. The system can generated up to 100 Grms over a frequency range of 5 to 10,000 Hz in three axes and rotational about each axis. Eight standard models are available ranging from 1 to 36 square feet.

For HALT and HASS testing the vibration systems are installed in specially designed environmental chambers capable of temperature change rates of 70°C per minute. The chambers have a temperature range from –65 to 200°C. More information is available at: http://www.hanse-environmental.com

For 15 years Hanse has been a global supplier of Environmental Stress Systems, HALT/HASS, specialized environmental chambers, environmental processing systems, and six-degree-of-freedom vibration systems. Hanse has concentrated on their engineering efforts to continually improve their products. The result is system performance that leapfrogs the industry as witnessed by this new invention.
