Frequently Asked Questions
There are many benefits of performing HALT/HASS Tests :
It helps to reduce product development and design time. It helps to ensure product quality & reliability. It helps to boost customer confidence. It helps to speed up time in the market. It helps to increase profit margins. It reduces warranty costs.
HALT tests are performed to find product design weaknesses which help to make products more rugged.
HASS is used to find flaws and defects during production for monitoring the quality and consistency of a particular manufacturing process.
A statistical strength distribution exists for any product. Where the Product Strength and Field Stress Curves intersect in red, failures will occur. HALT/HASS tests can cause the weaker components in the chamber to fail. The Commodity Intensity curve will be moved to the right by HALT and HASS. HALT/aim HASS's is to create a wide design margin or distance between the two curves, resulting in fewer field failures and a more reliable product.
A highly accelerated life test (HALT), is a stress testing methodology for enhancing product reliability. ... HALT can be effectively used multiple times over a product's life time. During product development, it can find design weakness when changes are much less costly to make.
