Hi Technetters:

We all know ANSI J-STD-001 provides the inspection guidelines
for quality. What one never comes across is data correlating
the numbers prescribed in the standard and quality/reliability issues. 
Most of the requirements mentioned in the J-STD-001 are either
cosmetic or not measurable by well-established inspection
techniques. Moreover, the implications of the standard on
board, assembly, and process design is not clearly understood.

I am posting this message to announce that we are initiating
a research effort at Rensselaer that will focus on the above issue.
In 1988 we had performed a study here at Rensselaer on 
this topic which revealed that (post-reflow) component tilt lowered 
the cycles to failure more than any other investigated variable.
This has been published in several articles and books. 
At that time it was felt that the emerging standards would 
include some reliability and performance criteria. (which has
not happened to date!)

We now propose to back parts of the J-STD-001 with quantitative data
as part of the 3rd phase of our Electronics Manufacturing Program.
Other focal areas include Intelligent Manufacturing, Solder/joint
characterization, Innovative soldering approaches, Alternatives to
soldered interconnects, Recycling issues, and Online design and
brokering. This program is an integrated effort with as much 
interaction between the focal areas as applicable. 

A kick-off meeting will be held on November 21st, 1996 at
Rensselear Polytechnic Institute, Troy, NY to incorporate the
opinions and suggestions of the attendees into the research program.
Companies participating in the program will have direct access
to the results and technical publications.

Take a look at our web site

for more information. You can also contact me for further details.
