The resnets are "innies" as you so eloquently described
:-)
I'm using the laser algorithm for chip components on the
Juki
The resnets measure ok on the laser - same result as digital
calipers...
Are the "innies" causing some weird reflection with the laser
when rotating the component for centering?

<< Hi guys and gals,
I'm having some problems
placing a resistor network component (1206).
Sometimes there is a
slight rotational error on placement, sometimes the
component is out in the x
axis (at 0 or 180 deg rotation)
or out in the y axis (at 90 or 270 deg
rotation).
The machines are Juki 750 & 760 (using laser
centering)
Other components are centering fine...
Any
ideas???
Help!!!

Hi
Justin!
I don't know if you know, but there's two types of chip resistor
networks.
What I call a "innie" and a "outie". The "outie" has what looks
like leads
for the terminations, like my ascii drawing below:

A "innie" has castellations for the
terminations...

The "innies" you can program like a
1206, the "outies" you have to program
like a leaded component, because the
laser sees the body and then the "leads"
off of the body...
Let me
know if that doesn't work...
