Artwork’s packaging software reads a technology file that can be used to control how these programs work. Currently the technology file enables a user to customize the layer names and colors generated by Bondgen and Wirebond programs. In the future we will add more sections to the technology file so that the user can futher control options.
The Technology File Format
The basic format of the technology file is based on the Windows .ini format. Sections are started with a keyword in square brackets [xxxx]. Variables follow the section head and use the syntax VARIABLE=Value.
The Technology File Header
[DATABASE] indicates this is the database descriptor TYPE=TECHNOLOGY indicates the file is a technology file VERSION=2.0 the version of the file UNITS=UM units for any dimension data (UM |MM|CM|MIL|INCH)
The Layer Section
Currently the layer section is used to control the actual AutoCAD layer names created for various functions. This enables users to create layer names that are consistent with their own layer naming schemes. The layer section begins with the keyword LAYER as shown below.
[LAYER] <layer> = <name> or <layer> = <name>, <color>
If a layer is not defined then a default name and color are assigned. A list of available layers with default names and colors are shown in the table below. Allowed colors are RED, YELLOW, GREEN, CYAN, BLUE, MAGENTA and WHITE. Use WHITE for black when using a white background.
