Allocating the new pin model to the current pin group
IIf several pin models were already defined, the data of the models are displayed in the "Models" selection
field (see Fig. 6.1.20) and can thus be allocated to the current pin group.
The entry for a pin model comprises the following data:
Num
= Number of the pin model
Len
= Length of the pin model
Wid
= Width of the pin model
LTo
= Length tolerance of the pin model
WTo
= Width tolerance of the pin model
CoL
= Contact length
CoW
= Contact width
Procedure:
●
Select the data of the desired pin model from the "Models" selection field.
●
Click on
OK
.
The window is closed. The pin group is displayed in the view area with the dimensions of the
selected pin model.
Defining a new pin model
●
From the view area select any pin of the newly created group by double-clicking. The window for
editing the data for the pin model is opened (see Fig. 6.1.21).

In the following, the meaning of the individual editing fields for the pin data is explained (see also
Fig. 6.1.18 and Fig. 6.1.19).
-
Pin length
[mm] length of the pin
-
Pin width
[mm] width of the pin
-
Pin length tolerance
[mm] max. permissible deviation from the pin length
-
Pin width tolerance
[mm] max. permissible deviation from the pin width
-
Contact length
[mm] length of the pin that makes contact with the PCB
-
Contact width
[mm] width of the pin that makes contact with the PCB (
^
pin width)
NOTE
From some values of the pin data the default values for the remaining pin data can be derived:
e.g. pin width (Wid) = contact width (CoW)
pin length (Len) > contact length (CoL)

Editing possibility no. 1:
●
Click on editing field "Pin length".
●
Enter value and complete entry by pressing RETURN. (The graph. display is updated).
The automatically computed default values are entered in the fields "Pin length tolerance" and
"Contact length".
●
Click on editing field "Pin width".
●
Enter value and complete entry by pressing RETURN. (Die graf. Darstellung wird aktualisiert).
The automatically computed default values are entered in the fields "Pin width tolerance" and
"Contact width".
●
Change default values, as required, and complete each entry by pressing RETURN.
NOTE
If invalid values (e.g. excessive value for the pin length) or characters (e.g. letters, or a comma as
decimal point) were entered, the field being edited is surrounded by a red frame and the entry must
be corrected.
●
Completion of entries to be confirmed by clicking on
OK
.
The window is closed.
