HALT & HASS system

Highly accelerated life testing (HALT) is used to add more stress to the DUT, so that the product design flaws exposed time is much shorter than the time required for reliability under normal stress conditions.
The purpose of the testing is to identify the operation and destruction limits of products during product development stage, to help customers improve design and build reliable products.
  • Quickly discover products' design weakness and destruction limit
  • Analysis and improve products' designing limits
  • Helping customers build reliable products
  • Reduce time and cost of research and development
  • Eliminate the design weakness before manufacturing
  • Provide the basis for continuous evaluation of product improvement.
Highly accelerated stress screening (HASS) is different from highly accelerated life testing, is mainly used in the screening process after production. The stress of highly accelerated stress screening is smaller than highly accelerated life testing, but generally still higher than the designing stress limits.
The purpose of highly accelerated stress screening is to find products' quality defects within a very short period of time. And the highly accelerated stress screening is based on the highly accelerated life testing.
  • Optimized product design and production processes
  • Improved products' quality and reliability
  • Low maintenance cost
  • Reduce products' early failure rate
HALT & HASS can provide the tests of vibration synchronization, temperature synchronization, vibration and temperature cycling and shock, integrated vibration and temperature and so on.
HALT & HASS have two working modes which are repetitive shock HALT & HASS and electro-dynamic HALT & HASS. And STI can provide both working mode test systems.
