Morning Technet, We're in the process of evaluating different AOI machines to put after our SMT reflow ovens. I've been trying to read up on AOI, and have seen differences in machines such as 2D imaging vs. 3D imaging, differences in lighting sources (xenon, lcd, etc.), vector imaging vs. grey scale correlation, etc. I wanted to query the Technet crowd to see what kind of knowledge/experience you all have on AOI and maybe even on specific machines. Thanks, Robert Vega Rockwell Collins --------------------------------------------------- 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 -----------------------------------------------------
