Bob,
Werner's article
Engelmaier, Werner, "How to estimate solder joint reliability, part
2," Global SMT and Packaging, vol. 7 no. 10, pp. 64-66, Oct. 2007.
can be downloaded from
http://www.globalsmt.net/documents/Issue_Archive/7.10%20US_opt.pdf
starting with page 64. This issue of Global SMT and Packaging is a
free 12MB download.
This reference and link are in the "Papers, Reports, and Magazine
Articles on Lead-Free, RoHS, and WEEE" section of my Bibliography for
Designing Lead-Free, RoHS-Compliant, and WEEE-Compliant Electronics at
http://www.dbicorporation.com/rohsbib.htm
which covers:
* Over 250 books,
* Over 220 Ph. D and Masters theses, and
* Well over 15,800 papers, magazine articles, reports, web pages, etc.,
all on lead-free electronics, the RoHS and WEEE Directives, and similar
legislation, which I have collected since December 2004.
I personally do not trust the quality, reliability, or lifetime of any
consumer electronics-- and most professional electronics-- manufactured
since the beginning of 2006, specifically because they are/may be
lead-free. Since 2005 I buy new electronic products only if I:
1. Can't find a satisfactory, used, pre-2006 product on Ebay.
AND
2. Believe that the new electronic product will pay for itself within
3 months.
If I buy a new, cheap electronic/electronic product, such as an LED
flashlight, I'll usually buy three of them, in the hope that at least
*one* of them will work when I need it. If I buy an expensive
electronic/electrical product, I'll get the longest extended warranty
that the seller offers.
I have been studying electronics since 1960 and have been working
fulltime in the electronics/computer industry since 1973. From 1973 to
2002 I helped develop, or developed manufacturing testers for, 115
state-of-the-art electronic products at Sycor, IBM, and Lexmark. Since
2002 I have done the electromagnetic compatibility (EMC) approval
testing of over 230 products for dBi's clients. My first book
Electronic System Design: Interference and Noise Control Techniques
was published by Prentice Hall in 1987. Mir published a Russian
translation of it in 1990. My second and third books, Robust Electronic
Design Reference Book, Volumes I and II, were published by Kluwer
Academic Publishers in 2004.
