Well, I can produce a registration target in BMP for you, but I'll have to
spend the same 10 minutes that you'd hve to spend. Normally, the things
look like a circle with a centered crosshair over it. What's also
frequently seen is a mounting hole sized to accomodate a dowel pin to keep
the panels aligned for routing. That's just a mounting hole drilled in the
center of strategically placed alignment targets.
If I send you a BMP image of a target, can you size it with your software,
or do you need several sizes?

Dick:
EDWin has the ability to build components and symbols. It also has
the ability to embed a BMP file. So, I was hoping that someone had a
registration mark in a popular graphics format for me to embed without
having to go through the trouble of building a symbol.
I have a copyright legend in the component side copper and
"component side" text in the silk screen.

The packages I've used (2 versons of OrCAD and EAGLE) seem not only to
provide registration targets, but certainly provide sufficient utility to
build such a symbol if it didn't already exist. Have you considered
making
your own registration target?
If you do build it, be certain it's different from one side of each layer
to
the other. If you include a bit of text, i.e. a layer
identifier in your
registration target, that will help quite a bit. You may also want such
an
identifier separate from the target, so you can be
certain all the layers
are present when you look at a registered set of layer overlays. It must
be
obvious which is which, however, as it's easy to
reverse a layer if you
have
both reversed text and "right-way-around"
text in the copper.

EDWin
CAD does not
appear to have built-in registration mark graphics.
I did a search for electronics clipart, but the 11 sites had nothing
useful.
Does anyone have any useful registration bitmaps they can send me?
