Reliability Lab Testing Services:
All testings are performed by Certified Reliability Engineers. Our professional standard goes beyond mere “shake, rattle, and roll testing” or simply issuing standard certificates.
HALT and HASS Labs® & Testing
Our own HALT and HASS Labs® are within a short drive from the San Jose Airport. It is the 2nd longest running HALT & HASS lab in the world, since 1995. HALT & HASS Labs contains 3 separate Lab areas, to provide privacy and security for products not yet in the public.
Many companies have uncovered design weaknesses and improved the design margins for more reliable products after using our labs. The operating and destruct limits discovered during HALT (Highly Accelerated Life Test) can also be used to develop an effective HASS (Highly Accelerated Stress Screen) for manufacturing. HASS will quickly detect any process flaws or new weak links without taking significant life out of the product. The HASS process can ensure that the gains realized through reliability engineering from HALT will be maintained in future production.
Other Test Services
Our in-house labs also support a number of environmental test conditions such as application of temperature, vibration and humidity.
We also provide additional environmental testing, solar, UV, SALT spray testings, ESD (electro-static discharge), EMC (electromagnetic compatibility) and safety certification, such as such as UL, CE, and failure analysis, together with our network of lab partners.
HALT / AFR Calculator
Our unique and proprietary HALT / AFR Calculator is the first ever calculator that can predict field reliability from HALT Results.
What is “HALT”?
HALT is primarily a margin discovery process. Throughout the HALT process, the intent is to subject the product to stimuli well beyond the expected field environments to determine the operating and destruct limits of the product. Failures that typically show up in the field over a long period of time at much lower stress levels are quickly discovered while applying high stress conditions over a short period of time. In order to ruggedize the product, the root cause of each failure needs to be determined and the problems corrected until the fundamental limit of the technology for the product can be reached.
This process will yield the widest possible margin between product capabilities and the environment in which it will operate, thus increasing the product's reliability, reducing the number of field returns and realizing long-term savings.
Typical stresses using during HALT are cold step stress, hot step stress, rapid thermal transitions, vibration step stress, combined thermal and vibration environments, and any other electrical and environmental stresses that are appropriate (voltage margining, frequency margining, etc).Read More
What is “HASS”?
A Highly Accelerated Stress Screen (HASS) is a process comprising a set of stresses performed to find potential defects on a product before it is shipped. The stresses are tailored to the product during the HASS Test Development process based on information gathered during the HALT testing process. The key to a successful HASS test is imposing just enough stress to expose defects without aging the product beyond what it is warranted for.Read More
