Castellated PCBs: Design, Applications, and Manufacturing Considerations
Introduction to Castellated PCBs Castellated printed circuit boards (PCBs) represent a specialized design approach that enables modular electronics assembly and simplified board-to-board connections. These unique PCBs feature a series of semi-plated holes or indentations along their edges that resemble the battlements of a castle—hence the name “castellated.” This distinctive edge configuration serves as both a…
