When comparing the durability of Multilayer PCBs vs. Flexible Printed Circuits, the winner depends entirely on the application. Flexible circuits excel in environments with constant bending, vibration, and tight space constraints due to their inherent pliability. In contrast, rigid multilayer PCBs offer superior structural integrity and resistance to direct impact and punctures. The choice is less about which is inherently ‘stronger’ and more about matching the board’s properties to the specific mechanical and environmental stresses it will face throughout its lifecycle.
