Speaking of stencils, a couple years ago, I talked a company into assuring
Gerber data was made available to those stencil suppliers capable of
performing AOI inspection. Photo Stencil, in CO, I believe started using the
inspection method.

I raise this question because so many of the aperture and dimensional issues
should have been resolved before receiving the stencils where I was working.
Really got tired of using some supplier's product and having to tape up or
re-order new stencils whether a result of design or process issues - most
offen the former.

In fab shops, as everyone knows, AOI is a very important and logical tool to
inspect the results of the etch process, and all leading to it. As the same
basic technology uses Gerber or, more importantly, ODB++ data, it only seems
resonable everyone is now, or has been, jumping on the bandwagon.

Very curious,

MoonMan
