Plated Half-Holes

Plated Half-Holes (Castellated Holes) are critical edge interconnect structures in modern PCB design. They enable reliable module-to-board soldering, improve space efficiency, and enhance assembly accuracy for high-density electronic products. What Are Plated Half-Holes (Castellated Holes)? Plated Half-Holes (Castellated Holes) are semi-circular copper-plated holes located precisely at the edge of printed circuit boards. They act as…

Plated half-holes, also called castellated holes, provide a space-efficient way to interconnect separate PCB modules by soldering. Unlike bottom pads, their edge positioning simplifies mounting and enhances reliability. This article explains everything about plated half-hole structures, design guidelines, manufacture, benefits and use cases. Structure of Plated Half-Holes Plated half-holes, also known as castellated holes, resemble…

Plated half-holes (also known as castellated holes) offer a space-efficient, reliable method for interconnecting PCB modules through direct soldering. Positioned at board edges, they simplify assembly, improve alignment, and boost mechanical stability compared to traditional bottom pads. This guide covers structure, design rules, fabrication, benefits, applications, and best practices for engineers and buyers. What Are…
