PCB Via Plugging Solutions: A Comprehensive Guide

Introduction Printed Circuit Boards (PCBs) are essential components in modern electronics, enabling the interconnection of various electronic parts. Vias—small holes drilled into PCBs—play a crucial role in establishing electrical connections between different layers. However, via clogging (or via plugging) is a common issue that can lead to manufacturing defects, poor solderability, and reduced reliability. This…
