TO: I4235700 IBMMAIL new address for ipc technet 25.6.96
FROM: DSTEWART EX2 D.Stewart - Product Development Manager.
DATE: 9 July 1996
SUBJECT: HAST
REFERENCE: highly accelerated stress testing
We performed HAST (highly accelerated stress testing) on product
for a particular customer some years ago, which was designed to
take the product to failure in order that failure modes could be
analysed and product life determined. Does anyone out there
recognise the term HAST, and if so could you provide details
(non-proprietary) on what the testing involved. We are particularly
interested in relation to the new types of circuit constructions
with micro blind vias (SBU, laser drilled, Dyconex etc).
Thankyou
