For 20 years we have been a global supplier of Environmental Stress Systems, HALT/HASS, specialized environmental chambers, environmental processing systems, and six-degree-of-freedom vibration systems. We have concentrated our engineering efforts to continually improve our products. The result is system performance that leapfrogs the industry. . . . and we can provide you with a complete turnkey integrated testing system. I would like to personally invite your inquiry.
Sincerely, John K. Hanse
Today, we manufacture the largest standard line of what we believe to be the most advanced performing HALT/HASS chambers in the industry. We have concentrated our engineering efforts to advance the state-of-the-art of HALT/HASS chamber performance.
Eight models are standard. Customized configurations are available also. Temperature cycling and six-degree-of-freedom (6DoF) vibration systems are available in eight stand-alone models
In addition, we design and manufacture specialized environmental chambers (humidity, corrosive, temperature/humidity, etc.) with extreme performance requirements.We also design and manufacture manufacturing processing equipment which requires environmental conditioning. We take pride in providing not only an equipment response, but also a solution to many challenging requirements.

Environmental stress screening (ESS) is one of the most widely used of all accelerated reliability tests. It precipitates latent defects, which are detectable only with the application of stress. Latent defects are introduced into the product during manufacturing, since design-related defects should have been detected and eliminated by reliability-enhancement testing during the design phase.
The short lifecycle of today's electronic products creates many pressures for rapid development and manufacture of new products, or product upgrades, in order to stay ahead in the competitive market place. Take for instance, the short model life of computers and printers. A new model appears every few months. Time-to-market is short, and customers expect the new models to work "out of the box" each and every time.
These pressures can result in compromised product development and/or manufacturing problems caused by part, process, and workmanship defects. The result is increased manufacturing costs, warranty costs, impacted profit margins, and sadly worse, customer dissatisfaction with resulting loss of market share.
Since the early 1980's there has been much discussion regarding various approaches and methods in the use of environmental stress screening and Halt/HASS to markedly improve product quality and life. Unfortunately, there was widespread misunderstanding and misapplication of the methodology . . . . and some still remains. Accordingly, we have listed the "Seven Deadly Sins of HALT/HASS".
There are always beginners in any field. The economic conditions over the past year or so have changed the business climate. Many are opting to take early retirement if offered. Because of massive layoffs, people are being asked to do work that they have never done before. Mergers may mean that you suddenly own equipment that you don’t know how to use. And there will always be people new to a field out of their own choice – perhaps fresh out of college or transferring from another department.
Working with HALT is an exciting challenge. I’ve been deeply involved with the process for over a decade now. I meet a lot of engineers that have a very good understanding of the process, but have lately been seeing that there are a lot of people who don’t know very much about it and would like to learn more. There is also a crowd who would rather debate semantics that get down to work.
Let me start by saying that there is no one right way to run HALT. Let’s take a minute to review what HALT is, and what HALT isn’t.
Today we manufacture the largest standard line and what we believe to be the most advance performing HALT/HASS chambers in the industry. We have concentrated our engineering efforts to advance the state-of-the-art of HALT/HASS chamber performance.
