Hello out there in cybertechland,

We have a high mix captive OEM assembly operation, probably build about 1
kits weekly of 50-500 pcs. A problem is the verification of SMT machine
setup on first article.

We have many population option variants, so the boards have RAM sites, etc.
which are either populated or not based on configuration.

When the first board is off the P&P machine, we typically give it a 5
minute visual check against a "checkpaper" drawing which is marked with
many cute color codes to indicate the proper component locations, along
with hand written markings to show the component brand and value.

I have a goal to make this all based on video or digital images. I am
looking for a suitable CCD video camera which can resolve image details and
produce an image about 2X normal size on a monitor to be installed right on
the SMT line. If we do video captures on each board, we could then compare
to the image on the monitor.

We have tried cheap digital cameras (not enough resolution) and our CCD
video camera has good resolution, but the max image size on the zoom lens
we have is about one inch.

If you have been down this road, suggestions would be welcome.


regards,
