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.

    FUNCTIONAL LAYER        DEFAULT NAME           DEFAULT COLOR

     BGA_GEOMETRY          ACS_BGA_GEOMETRY          GREEN
     BGA_PAD               ACS_BGA_PAD               WHITE
     BGA_TEXT              ACS_BGA_TEXT              BLUE

     DIE_GEOMETRY          ACS_DIE_GEOMETRY          RED
     DIE_PAD               ACS_DIE_PAD               WHITE
     DIE_TEXT              ACS_DIE_TEXT              BLUE

     FINGER_PAD            ACS_FINGER_PAD           BLUE 
     FINGER_TAG            ACS_FINGER_TAG           WHITE
     FINGER_TEXT           ACS_FINGER_TEXT          WHITE

     RATSNEST              ACS_RATSNEST             WHITE

     RING                  ACS_RING                 RED

     TEMP                  ACS_TEMP                 RED

     WIRE                  ACS_WIRE                 WHITE
     WIRE_DRC              ACS_WIRE_DRC             RED
Example of a Layer File
