HALT, HASS & HASA Explained: Accelerated Reliability Techniques

摘要

The author asserts "this book has been written with both novices and experts in mind." Further, the material is presented in a manner such that a reader may obtain sought after information "without getting bogged down in equations." At the outset he clearly delineates the intended meaning of the acronyms HALT, HASS, and HASA. Generically, HALT is a test regime employed to obtain information during the pre-production phase useful to designers for identification of weaknesses in parts, materials, and processes, which may be corrected to ruggedize the product. HASS is a test regime employed during the production phase. It is a production screening for the verification of the ruggedized product characterized in HALT. HASA employs essentially the same tests as HASS but as a production audit (sampling plan) as opposed to screening (100% of the product).
