For example, the row of the leads in N direction shown in
Figure 5
can be defined by the
coordinates of the tip position (
part in the figure) of the leftmost lead as a reference lead
position X and reference lead position Y, while the lead length will be defined as “length”, the
lead width as “width”, the lead pitch as “pitch” and the number of the lead as “n”.
Figure 5
It is also possible to define the row of the leads in S, E and W direction in the same way.
When defining these directions, the points used as the reference are as follows:
- The S direction: the leftmost lead
- The E direction: the uppermost lead
- The W direction: the uppermost lead
(In
Figure 5
, the lead with
mark is the reference lead, and its tip is the reference lead
position.)
As shown in
Figure 6
, when the leads in a single direction have different width and pitches,
they are divided into two groups and then defined. For example, the row of leads in the N
direction shown in
Figure 6
can be defines as follows:

<< Group 1: Left-side group in N direction >>

Lead length: length 1

Lead width: width 1
Lead pitch: pitch 1
Number of the leads: n1
<< Group 2: Right-side group in N direction >>
Reference lead position X2
Reference lead position Y2
Lead length: length 2
Lead width: width 2
Lead pitch: pitch 2
Number of the leads: n2
As shown in Figure 6, the groups are specified as Group1 and Group 2, from left to right in the
N/S direction, and from top to bottom in the W/E direction.
The definitions are made in the same way for the S, E and W directions.
This is how to define the component shape. Detailed setting items for the component data are
