You can cut these PCBs into any shape or size to meet your needs. Compared with professional PCB boards, perforated boards offer a lower threshold for use, lower cost, easier handling, and flexible expansion. The board is made of FR4 full glass fiber plate, which helps prevent pads from lifting off. The board is a circuit board covered with pads arranged at standard IC spacing (2.54 mm), and can be populated with components according to your own design. Because it resembles a grid of holes across the board, it is also called a hole board. Compatibility and practical notes: pads are designed on a 2.54 mm grid to accommodate standard throughhole component insertion and wiring as you lay out your circuit. Material and durability: FR4 full glass fiber construction provides mechanical stability and helps keep pads secure during handling and prototyping. Size and flexibility: cut to any shape or size to suit your project, enabling custom layouts for compact or irregularly shaped assemblies. Performance characteristics: suitable for quick prototyping and educational use where low cost and easy modification are important. Applications and use scenarios Quick prototyping and testing of circuits in hobby projects or earlystage concepts, allowing rapid layout changes without specialized equipment. Education and training in classrooms or maker spaces to teach circuit design, component placement, and basic PCB concepts. Smallbatch DIY electronics projects, work, or custom hobby projects that require a lowcost, adaptable board with standard 2.54 mm component spacing.
