The cons and pros of using Flexible PCBs design
When we speak of PCBs, we imagine a rigid board with components. In more complex electronics PCBs may be stacked on top of each other of interconnected with wires. However, the geometry of rigid boards in many cases define the shape of electronics devices. If devices are significant such as TVs, computers, then rigid boards find their place. However, even large devices become limited by rigidity. If you try to disassemble a modern TV or another device, you will find that not all boards are rigid. For instance, an LCD display is using a flexible printed circuit (FPC) and a flexible flat cable (FFC), which can be conveniently bent without taking much space. This allows laptop screens to be so thin. In modern electronics circuit boards can find their place regarding the shape and size of the device. Smartphones are stuffed with flexible circuits – cameras, speakers, batteries, displays are connected using FFC. Emerging folding smartphones have even tighter FPC fit. Flexible printed circuits usually mimic the rigid boards – the only difference is the base material used. Instead of…
