There should be at least one side with 2 body detection points, or there should be
at least two sides with one body detection point each.
(This part has 4 sides with 2 detection points each.)

Figure 9
Example part with leads not connected to the white areas
To determine whether or not the leads and white area are
connected, observe the part and imagine how the lead will
be seen by the parts camera. Refer to the picture on the left.
The gull-wing leads made shadows around the lead bases.
We see the leads and white area as being separated. The
gold leads are bright and easily seen. The gull wing angle or
lead width makes the lead base appear dark. If VPDPlus and
the camera stand are available, use that to acquire an image
of the part. That is the easiest way to see how the machine
will see the part.

4.7 Compatibility with Existing Part Data
4.7.1 Background
Previous Fuji machines support both backlight and frontlight systems, however, the NXT
machines support frontlight only. As a result, it is necessary to convert existing part data
created for used with a backlight system to enable the part to be processed using a
frontlight system. The NXT machines are equipped with a feature that enables automatic
conversion of part data created for backlight systems, however, there are cases whereby it
is necessary to make settings in the "Override" field in Fuji Flexa for the part data of certain
parts. This section provides a compatibility table for the part data of existing machines and
the NXT machines, as well as details of limitations relating to the part data conversion
process.
It is important to point out that when making new part data, use the old vision type and p
patterns if the data is to be used on other Fuji machines. If the data is never to be used on
older Fuji machines (only NXTs are present), then use the NXT vision types and the
frontlight p_patterns.
