Types of PCB materials PCB materials can be broadly categorized into two main types: substrate materials and conductive materials. Substrate Materials The substrate is the base material on which the conductive traces and components are placed. It provides mechanical support and electrical insulation between the conductive layers. Common substrate materials include: FR-4 FR-4 (Flame Retardant…
