Royce is correct in his statement about OCV/OCR adding to increases false
calls due to the screening of different vendor components.
  I suggest if you are interested in this aspect of the AOI systems you
request an in house evaluation period so they may show their improvements
and discuss their roadmap in the area.

  In my previous posting I should have been more clear about Photon
Dynamics. It is true they are still honoring their warranties.  I have a
concern about their long and short term abilites since leaving the arena
and with the onset of their employees with this area of expertise
apparently starting their own company.

  We have also evaluated Teradyne AOI and while it did very well in a head
to head against Agilent and also was compared to the same head to head held
against Orobtech I found the editing of Teradynes system very tedious
especially when it came to light settings and lead definition.

  Orbotechs bright light Xenon bulbs seems to cover all the light spectrums
and lights the area clearly even with taller components in the vicinity.
  Their Z table keeps the inspection area in focus to prevent issues from
warpage due to pcb design or heat out of the oven.
   During my evaluation period with several companies on AOI I found
Orbotech to be outstanding in customer support.  We are running 3 shifts 7
days a week in most cases and with any new system certain issues arise.
They have been very responsive to our needs.
