A fully enclosed Component courtyard must be drawn on the F.CrtYd layer, with the following parameters:

• Courtyard uses 0.05mm line width
• All courtyard line elements are placed on a 0.01mm grid
• If the component requires a courtyard on the back of the PCB, a corresponding courtyard must be provided on the B.CrtYd layer.
• Where the courtyard depends on the dimensions of the physical part body, clearance is calculated from the nominal part dimensions.

Courtyard clearance should adhere to the following requirements:

• Unless otherwise specified, clearance is 0.25mm
• Components smaller than 0603 should have a clearance of 0.15mm
• Connectors should have a clearance of 0.5mm, in addition to the clearance required for mating of connector
• Canned capacitors should have a clearance of 0.5mm
• Crystals should have a clearance of 0.5mm
• BGA devices should have a clearance of 1.0mm
