What does 'thermal relief' mean in zone properties?
Thermal relief is a pattern that connects pads to zones with spokes to reduce heat transfer during soldering, making soldering easier.

How does 'clearance' affect zone configuration?
Clearance sets the minimum distance between the zone copper and other elements like tracks or pads to prevent short circuits.

What is the impact of associating a zone with a specific net?
Associating a zone with a net ensures the copper fill connects electrically only to that net, like ground or power, maintaining circuit integrity.

What is the main purpose of a zone in PCB design?
✗ Incorrect
Zones fill copper areas to create electrical connections like ground or power planes.
Which property controls the minimum gap between a zone and other PCB elements?
✗ Incorrect
Clearance defines the minimum distance to avoid shorts.
Thermal relief in zone properties helps to:
✗ Incorrect
Thermal relief creates spokes to reduce heat transfer during soldering.
Associating a zone with a net means:
✗ Incorrect
Net association links the zone copper to a specific electrical net.
Which of these is NOT a typical zone property?
✗ Incorrect
Component footprint is unrelated to zone properties.
