Scott,
I have two of these Dinolite scopes with the stand. I do not use them
much because of the picture quality. They do not seem to handle the
light reflecting over solder joints very well. I have attached two
pictures.
I do have an old Sony Camera that I use instead. It is on a boom so I
can get good angle views of fillets etc. The reolution is not great and
I can manually adjust the light according to the finish and angle.
I Like the BGA100 hand held cameras that has a prism at the end even
better. You can look at a 90 degree angle under BGAs or also straight. I
have not bought one yet, I have only tried it. These run about $3K.
These work much better. Try SMT-Source.com
Joe et al.
Does any of you have any experience with the keyence tools? They are
very expensive, but are they worth it?
Let me know where your research ends up.
