What are Antipads in PCBs?
Antipads are critical clearance areas in copper planes that prevent unwanted electrical connections between vias and power or ground layers in multilayer PCBs. This video explains how antipads work, why they are essential for signal integrity, and how their size affects parasitic capacitance, impedance control, and crosstalk. It also highlights the role of proper antipad design in improving power distribution, return current paths, and overall PCB reliability. These considerations are especially important in 4-layer, multilayer, HDI, and high-frequency PCB designs used in IoT, industrial, automotive, and aerospace applications.
