What is a Half-Hole PCB?
A half-hole PCB (Printed Circuit Board) refers to a type of PCB that incorporates vias with only partial plating or coverage. These half-holes are typically used to connect different layers of the PCB without fully plating the hole, often to save costs or reduce manufacturing complexity.
Characteristics of Half-Hole PCBs:
Design Flexibility: Half-holes can help manage space and routing on a PCB, allowing for more efficient design.
Cost Efficiency: They can reduce manufacturing costs by minimizing the amount of plating required.
Manufacturing Simplicity: They simplify the drilling and plating process compared to fully plated vias.
Common Uses:
Signal Routing: To connect different layers in a multi-layer PCB.
Cost-Effective Solutions: In designs where full plating is not necessary for performance or reliability.
