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. --------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
