Following is from the EMPF HelpLine in Indianapolis. Prepared by Tony 
Burnett, an engineer working in the area of X-Ray inspection of soldered 
connections. Tony has experience with several generations of Four Pi X-Ray 
Laminography systems, the Vanzetti laser solder/inspection system, and 
Robotic Vision Systems Inc (RVSI) laser inspection systems. Tony is a 
Category B (Government instructor / inspector) to MIL-STD-2000 and has been 
working in the area of solder acceptance criteria for the past several 
years.

It looks like a good contact for you would be Four Pi Systems in San Diego, 
CA.  However, they are in the transition process to Fort Collins CO because 
they were recently purchased by Hewlett Packard and may be difficult to 
contact.  A good contact would be Mr. Bruce Bolliger, Vice President for the 
sales division. His number is (619) 485 - 8551.   This will get you to the 
receptionist who should then be able to redirect your call.  They have sold 
systems worldwide and may be able to get you some contacts in several 
different parts of the world.

In addition, one of my colleagues has been working with another X-Ray 
manufacturer known as IRT.  IRT is located in San Diego, CA and as the trend 
seems to be, has recently been purchased.  Although the details are a little 
sketchy, it looks like IRT was purchased by Nicolet.  There are rumors that 
IRT/Nicolet  will start marketing another Solder acceptance system in the 
March '96 timeframe.  If this is of any interest to you, let us know and we 
will try to find you a contact.

This is a repeat of my request, I thought I would be trampled under foot 
with
Email about this subject not even sales people. If there is no in-house
standards that people want to discuss I will need to pick one out of the 
air.

A am currently compleating an inspection video for x-ray covering chip, J 
lead,
gull wing and BGA terminations and need to have some input on the criteria 
used
on these types of joints. I have already used the x-ray on my BGA training 
video
but would like some basic criteria. If any one has a standard that they use 
for
assesment and is willing to provide the criteria then the best can have a 
FREE
copy of the tape when compleated.
