What Is PCB Directory?
PCB Directory is a professional online service platform dedicated to the global printed circuit board (PCB) industry. It aggregates resources from manufacturers, assembly providers, and design service firms, facilitating efficient supplier matching through parameter-based categorization (e.g., material type, layer count, thickness) and geographic filters. The platform supports specialized requirements such as flexible PCB and ceramic PCB, streamlining supply chain collaboration in electronics manufacturing and serving as a critical industry information hub.
