A printed circuit board with pads spaced at standard IC pitch (2.54MM), designed for easy component insertion and custom circuit connections. Compared to professional PCB manufacturing, perforated boards offer advantages such as low cost, ease of use, low entry barrier, and flexible expandability. Bakelite board is known for its insulation properties, resistance to static electricity, wear resistance, and high temperature tolerance. It is commonly used in electronic products, insulating switches, variable resistors, machinery molds, and production line fixtures. It exhibits good electrical performance at room temperature and excellent mechanical processing characteristics. Paper-based bakelite laminate is one of the most widely used industrial laminates worldwide. Suitable for students, engineers, technicians, factories, hobbyists, and electronic enthusiasts.
