0° Description of Components
In order to work with component shapes which have uniform definitions, standard components are described using four
specific rules. This is known as the "0° description" position, which allows you to precisely define the pickup angle during
placement.
To describe the component shape of a component, the dimensions should always be taken from the corresponding data
sheet. Make sure that the component is always described as viewed from above.
The display area of the GF Editor always shows the 0° description of the component. This zero degree origin of the co-
ordinate system is always shown in the center of the GF Editor display area. The X axis points to the right and the Y axis
points upwards. The center of the component generally corresponds to the origin of the coordinate system. Rule 1 defines
the alignment of the component sides in the X or Y directions.
Rule 1: A nozzle with rectangular suction surface is aligned with its longer side along the X axis. The component X
axis is parallel to the nozzle X axis, when the nozzle picks up the component properly.
When picking up a component, the component X axis always points in the same direction as the long side of the nozzle
(exception: special nozzles with 90° rotation).
The X axis of the component does not necessarily have to be the long side of the component.
For example, if there are holes through the component, the the nozzle will have to attach at a 90° angle (see fig. (4),
nozzle =
).

Rule 2: Pin 1 is in the bottom, left corner or at the center of the component's left side. In the case of diodes, the an-
ode (+) must point in the positive X direction.
Rule 3: The side with the most leads is at the bottom.

Rule 4: If the component has a special feature, such as a wider lead, this special feature will be at the bottom.
Rule 1 has top priority, followed by rules 2, 3 and 4.
