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?
