The DIE_LOGO section is intended to allow designers to place within the die region small geometries that represent logos or alignment marks.

Logo Using Polygons as Text


POLY - polygon used to define the die logo geometry.

NUM_OF_POLYGONS - the number of polygons that comprise this logo. Generally if more than one, the additional polygons are cutouts.

WIDTH - for a polygon, the width of the edge. Normally = 0.

NUM_OF_VERTICES - the number of vertices to follow. (Note, first and last vertex must be explicitly stated so a "square" has 5 vertices.) If this number is negative, it indicates that the polygon is a "cutout."

X,Y - for a polygon the vertex coordinates are with respect to the reference coordinate - they are not absolute. Also the first vertex must be the same as the last to close the polygon.

  Example - Die Logo

Here is an example of a die logo.

Logo Using a Text String

It is also possible to use a string of text to stand in for the die logo. The syntax is shown below:

TEXT x,y height rotation justification string


x,y - text insertion coordinates

height - height of the text.

rotation - Rotation of the text (CCW from horizontal)

justification - L|C|R - Justification of the text (Left, Right, Center).

text_string - The string of text.

  die logo using a text string


TEXT 100,90 100 0 L SL6018/A1

In this example, the string of text is "SL6018/A1", and it is inserted at 100,90 with a height of 100, 0 rotation and Left justified. The actual font will depend on the system that is reading the string of text.
