  This part may be assembled using laser aligment, if you have a Philips
with laser system you can try.
  "Our designers see this coil as just another standard part, and they don't
want to hear about any such problems..." this is not what I should call
"team work"

Thanks

Subject: [TN] Pick&place of white coil


Hi All,

I just sent Steve a photograph that he genereously placed on in his
CyberHouse at http://stevezeva.homestead.com/index.html. It's a picture of a
Coilcraft coil with a white bottom and goldplated terminations.
Our designers are planning to use these parts on some of our new products,
but unfortunately the placement on our Philips (Assembleon) machines is
inaccurate due to the fact that there's not enough contrast for recognition
by the vision-system. Both the gold and the white substrate are highly
reflective when illuminated on the vision system.

Our designers see this coil as just another standard part, and they don't
want to hear about any such problems.
To my opinion it is ridiculeous that component manufacturers make their
parts like this (I mean they could give some surface treatment to their
alumina substrates).

I really like to know how other Techies think about this. Is this a standard
part that needs an in-house technical solution, or should a Smart Designer
try to avoid using such parts ?

Kind regards,

Daan Terstegge
