A San Diego based company by the name of 4-Pi
 marketed X-ray laminography units for electronic assembly inspection. They were
recently bought out by a well known firm. Anyone out there know who?

I am looking for a source for non-destructive inspection/analysis of 
top-side solder fillets on a DC/DC converter, soldered flush to the PWA 
(thru hole, single side).  I have already attempted X-ray.  Is the process 
of Scanned-Beam Laminography (SBL) or Computed Tomography (CT) available 
commercially for this application?
