Understanding Plated Half-Holes (Castellated Holes) in PCB Design
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…
