SMG Global Circuits Inc. is a trusted provider of advanced PCB fabrication services, supporting customers across industries that demand reliability, precision, and performance. Among its specialized offerings, PCB edge plating stands out as a critical capability for applications requiring enhanced mechanical strength, improved electrical performance, and robust board-to-enclosure connectivity.

PCB Edge Plating at SMG Global Circuits Inc.

PCB edge plating is a manufacturing technique in which the copper from the top and bottom layers of a printed circuit board is extended and plated along the board’s sidewalls. This process creates a continuous conductive surface around the PCB edge, strengthening electrical connections and providing additional protection against wear and damage.

Edge plating is especially valuable in designs where PCBs slide into metal housings or require dependable edge connections. By reinforcing the board perimeter, this technique also enhances current-carrying capacity and improves long-term durability in demanding environments.

Edge Plating Options Available

SMG Global Circuits Inc. offers multiple PCB edge plating configurations to meet diverse design and application requirements. Each option is manufactured with precision and consistency, ensuring dependable results for both prototype and production volumes.

Wraparound Edge Plating

Wraparound edge plating is achieved through additional routing operations performed after the initial PCB drilling process. This method allows copper to wrap from the top and bottom layers around the board edge, creating superior edge conductivity.

Compared to traditional via-in-hole approaches, wraparound edge plating can provide enhanced electrical performance and improved current distribution along the PCB edge. While not all PCB manufacturers offer this capability, SMG Global Circuits Inc. delivers high-quality wrap edge plated boards tailored to exact customer specifications.

Castellated Edge Plating

Castellated edge plating involves drilling a series of holes along the PCB outline and then plating them to form half-hole “castellations” along the board edge. Additional routing is performed after drilling to expose the plated features.

This technique is ideal for PCBs designed to be soldered directly onto a larger system or motherboard. Castellated edges allow for strong, reliable solder joints and are commonly used in modular and embedded applications. With extensive experience and proven manufacturing processes, SMG Global Circuits Inc. provides repeatable, high-quality castellated edge plating that many fabricators are unable to support.
