Method detail#

classmethod PadstackDef.create(edb, name: str) → PadstackDef#: Create a new padstack definition.

PadstackDef.convert_to_3d_microvias(convert_only_signal_vias=True, hole_wall_angle=15, delete_padstack_def=True) → bool#

Convert actual padstack instance to microvias 3D Objects with a given aspect ratio.

Parameters:

convert_only_signal_viasbool, optional: Either to convert only vias belonging to signal nets or all vias. Defaults is True.
hole_wall_anglefloat, optional: Angle of laser penetration in degrees. The angle defines the lowest hole diameter with this formula: HoleDiameter -2*tan(laser_angle* Hole depth). Hole depth is the height of the via (dielectric thickness). The default is 15. The lowest hole is 0.75*HoleDepth/HoleDiam.
delete_padstack_defbool, optional: Whether to delete the padstack definition. The default is True. If False, the padstack definition is not deleted and the hole size is set to zero.

Returns:

bool: True when successful, False when failed.

PadstackDef.split_to_microvias() → list[pyedb.grpc.database.primitive.padstack_instance.PadstackInstance] | bool#

Convert actual padstack definition to multiple microvias definitions.

Returns:

list[PadstackInstance] or bool: List of new microvias padstack instances, or False when conversion fails.

PadstackDef.get_pad_parameters()#

Pad parameters.

Returns:

dict

Dictionary with pad type names as keys and lists of layer pad parameter dictionaries as values.
