This 8-layer FR4 PCB addresses the challenges of high-density, narrow-format electronic designs, where space efficiency and signal integrity are critical. With dimensions of 165.50×25.90mm and a 1.6mm Dicke, the board provides a compact yet robust platform for integrating complex circuitry in applications such as industrial sensors, communication modules, and portable test equipment. Gebaut von FR4 material, it offers stable electrical insulation (Dielektrizitätskonstante εr = 4,5) and mechanical strength, suitable for operation in environments with moderate temperature and vibration.
