Describe the function of the plated edge
Edge plating places conductive metal on defined portions of the board perimeter. Depending on the design, it can provide a connection between copper regions, an interface to another assembly or part of an electromagnetic control strategy. The function determines which layers must connect and which must remain isolated.
Distinguish a plated perimeter from exposed copper at a routed edge, connector fingers and castellated half holes. Those features have different geometry and manufacturing requirements. State the intended feature on the drawing instead of relying on a photograph alone.
Define connected and isolated regions
Mark the exact edge segments to be metallized and the copper connections required at each segment. Review internal-layer clearances as well as top and bottom copper. An unintended connection to an internal plane can change the circuit even when the outer appearance is correct.
Specify the finished surface appropriate to the intended contact or soldering role. Wear, solderability and environmental exposure are separate requirements. Do not assume that a decorative metal finish or an unspecified gold layer establishes the needed contact performance.
Coordinate profiling and panel support
The required edges must be accessible at the relevant stage of the manufacturing process. Panel attachment locations can interrupt the plated perimeter. Agree which interruptions are permitted and show any edge areas that must remain continuous for function.
Review corners, cutouts, narrow features and the relationship to later depaneling. The process must preserve the intended metal coverage and avoid damage at the finished edge. A request for complete plating around every edge may require a different construction or support strategy.
Inspect the feature in its actual use
Define coverage, continuity, isolation and surface-condition acceptance, together with any relevant thickness or dimensional requirements. Electrical testing should reflect the intended net relationships. A continuity result alone does not establish adhesion, contact wear or environmental performance.
Provide the fabrication drawing, stackup, copper data, panel constraints and mating-interface details with the inquiry. For first articles, evaluate the edge in the intended assembly. Record any proposed plating interruption or copper change for design approval before the production files are frozen.
