Interesting images, can almost make out voids (slight white spots?)
It is strange that they 'all' seem to be oriented in the same direction, my
first thought was distortion from the xray not centered (like the image was
cut from a corner of the original image) but with studying I would say yeah,
they are definitely distorted in a common direction. Could the component
have shifted during assembly? Some form of pressure sliding the component in
a direction making the ball form that way? Also see what looks like the ball
actually off the pad? (appearance of filled in figure 8).
Have these been tested yet? My money's on long list-o-opens...

Hi Everyone!
DS sent me these images to post on my web page. Go to:
http://www.stevezeva.homestead.com and click on "Picture Page 2" then
look for: "X-ray 1 and X-ray2".
To me, these images are very fuzzy, and hard to tell anything for sure. The
spheres are definately not round like they should be, so that would be a
big
flag to me. As to what could be causing these images is hard to say because
they are so fuzzy, but I wouldn't feel comfortable letting something go
that looks
like this without further investigation.
Seeing how it's Friday, I got something on my page that's kinda' funny, if
not
really stupid...
Yesterday during the baseball thread, Chris Ball writes:
Based on that, I was gonna interject something about an anti-gravity ray
being a weapon of mass destruction, but it wasn't making any sense at
all. Then I realized.....
The mass of an object is not dependent on gravity and therefore is
different from but proportional to its weight.
(sigh)
Ask me a baseball question.
Then Franklin Asbell interjects:
"Interesting, so if I am sitting on a park bench and a 20' diameter
sphere smacks me in the head at appr. 20 mph, would I receive the same
headache if the same sphere hit me at 20 mph while I'm straddling the
space station, in outer space?
Then Richard Stadem responds:
No, because if you were sitting on a park bench the 20' sphere would hit
you in the head. However, if you were straddling the space station it
would probably hit you somewhere else where it would hurt more;)
and then Dewey Whitaker retorts:
That's why they call them Asstronauts.
So this video clip sums it all up. These guys are testing all the theories
that have been
outlined above, and then some...I wonder what conclusion they reached?
Take a look at; "Paintball.wmv"
These guys are the next Shuttle crew.....
Kind regards,

Dear All,
Can anybody tell me whether these x-ray images are acceptable. I found that
few outer ball are partially cut but still 90% pad is covered with the
solder . I could not find any reference in workmanship standard for this
kind of problem. Kindly help.
<<83.tif>> <<076.tif>>
Best Regards
DS Bhandari
