YES we are finally there! Machines that will do visual inspection of my PCBs and let me do my work with my eyes closed....almost sounds too good to be true....... We are at the point of implementing a visual inspection system, but really know little

Phil- A Technology you may want to give serious consideration is the Original Solutions UV-OS-1. No gold PCB's, 100% accurate,and a Money back guarantee - IMPRESSIVE! We did the studies on the Original Solutions Boards and were amazed with the techno

Steve, When you say "CAD input", do you mean centroid data ( xy locations ) or generic cad info straight from the layout software. ( so far the machines I have been looking at use centroid) What are your rates of "false failures" and how do your o

Some AOI manufacturers require you to put in a GOLD PCB. Gold PCB is a perfectly manufactured board - Correct placements, correct polarity, no solder short, a "GOOD" PCB. With the vision limitations of some AOI equipment components that have variatio

The CAD data is the centroid data, x,y location. I developed an Excel macro in which we import the data as a text file and convert it to the CR Technology format. Rates for false failures varies, but is ~10 - 20%. The operators are given an oportuni

We have been looking into some sort of higher level inspection system as well. But we have been fairly well convinced that X-Ray is far better than AOI. X-Ray is not only good for BGA's, it is also good for any solder related problems. AOI can onl

Genny, Xray systems ( or at least what I have seen ) are a manual based system. That is, you put the board on the machine and look at certain locations that you want to inspect. What we have in mind is an automated system that will catch obvious, no

Phil, The AOI will do a excellent job doing what you said you are looking for. We justified ours on the same requirements as you stated. Keep in mind that the machine may not "see" everything, there are some hidden joints that you will still need to
