Highly Accelerated Stress Screen (HASS)
Any product and even well designed ones could experience high rate of early life failures. This could be attributed by the variability in the manufacturing process like solder joints or components. HASS is an accelerated production level screen test that is based on the HALT methodology and can reveal latent flaws not detected by the standard environmental stress screening or burn-in. The goal is to find the marginal types of defects that are in the category of infant mortality and manufacturing failures. The FMECA results can be helpful in identifying the proper screen for the product.
We provide the following HASS services:
- Highly Accelerated Stress Screening Plan
- HASS execution which includes testing, monitoring and the final report
On-Going Reliability Testing (ORT)
The objective of ORT is to ensure the current product manufacturing process is still producing the same quality products with the same specifications as the first day went into the production. This testing requires to randomly selecting a number or percentage of products that are going through the manufacturing line and put them in an elevated temperature chamber. The information from latent failures experienced during the manufacturing should be used in the ORT profile.
We provide the following ORT services:
- On-Going Reliability Test Plan
- ORT execution which includes testing, monitoring and the final report
Product Aging - End-of-Life Assessment
In the early phases of the product design, we predict the end-of-life based on the components and technologies used in the design. In the deployment phase after the product has been release to the market, companies decide what is the end-of-life of their product. We use the field data and calculate the product end-of-life by identifying when the wear-out is starting. This analysis helps to define the last time buy, potential RMA and spares impact and how to mange customer expectation of product performance in the field. This analysis could be used as a tool for offering more product and services to customers. Also, end-of-life analysis help manage service contracts terms and conditions. The analysis is performed at system or sub-system level by collecting the field data and applying data analysis method such as Weibull to identify the start of wear-out mode.
