int pga_create_packages_list ( )

Create a list of PGA packages with pre-defined values.

The data in this list can be used in a combobox to select a pre-defined package.

Returns:: EXIT_SUCCESS when a packages list was created, EXIT_FAILURE when errors were encountered.

Definition at line 294 of file pga.c.

int pga_drc ( )

Do some Design Rule Checking for the PGA package type.

check for allowed pad shapes.
check for zero sized packages.
check for a zero sized courtyard.
check for minimum clearance between copper (X-direction).
check for minimum clearance between copper (Y-direction).
If any fiducials exist:
- check for zero fiducial pad diameter.
- check for zero width solder mask clearance.
- check for minimum clearance between copper (between pads and fiducials, if any fiducials exist).
check for clearance of the package length with regard to the courtyard dimensions.
check for clearance of the package width with regard to the courtyard dimensions.
check for any silk lines or texts touching bare copper.
check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).
check for a reasonable silk line width.

Returns:: EXIT_SUCCESS when no DRC violations were encountered, EXIT_FAILURE when DRC violations were found.

If any fiducials exist:

check for zero fiducial pad diameter.
check for zero width solder mask clearance.
Todo:

Todo:: Check for any silk lines or texts touching bare copper.

Todo:: Check for soldermask clearance (solder mask overlapping copper at the solder fillet area or worse).

int pga_get_default_footprint_values ( )

Look up default values for PGA footprints.

Footprint values can be looked up by placing a question mark "?" in front of the footprint name.
If the footprint name is recognised the values will be loaded and the entries involved in the GUI will be updated accordingly.
Currently the following footprints are supported:
-.
