PCB News - Advantages of PCB flexible circuit

PCB flexible circuit is designed to improve space utilization and product design flexibility, which can meet the design needs of smaller and higher-density installations, and also help reduce assembly processes and enhance reliability. It is the only solution to meet the miniaturization and mobile requirements of electronic products. Flexible circuits are copper circuits etched on polymer substrates, or printed polymer thick film circuits. For thin, light, compact and complex devices, the design solutions range from single-sided conductive lines to complex multilayer three-dimensional packaging. The total mass and volume of the flexible package are reduced by 70% compared to the traditional wire harness method. Flexible circuits can also increase their strength by using reinforced materials or liners to achieve additional mechanical stability.

PCB flexible circuit can be moved, bent, twisted without damaging the wire, and can have different shapes and special package sizes. The only limitation is the volume space issue. Because it can withstand millions of times of dynamic bending, the flexible circuit can be well applied to the internal connection system of continuous movement or regular movement, and become a part of the function of the final product. Some products that require electrical signals/power to move and a smaller form factor/package size benefit from flexible circuits.

PCB flexible circuit provides excellent electrical performance. The lower dielectric constant allows the rapid transmission of electrical signals; the good thermal performance makes the components easy to cool down; the higher glass transition temperature or melting point makes the components run well at higher temperatures.

Since the hardware required for internal connections is reduced, such as solder joints, relay lines, backplane lines and cables commonly used in traditional electronic packaging, flexible circuits can provide higher assembly reliability and yield. Because the traditional interconnection hardware composed of multiple complicated systems is prone to high component misalignment rate when assembling. With the advent of quality engineering, a thin, flexible system is designed to be assembled in only one way, thereby eliminating the human errors usually associated with independent wiring projects. Early flexible circuits were mainly used in the fields of connection between small or thin electronic products and rigid printed boards. In the late 1970s, it was gradually applied to electronic products such as computers, digital cameras, inkjet printers, car stereos, optical disc drives (see Figure 13-1), and hard disk drives. Turn on a 35mm" camera, which contains 9-14 different flexible circuits. The only way to reduce the volume is to have smaller components, more precise lines, tighter pitches, and bendable objects. Pacemakers, medical equipment, video cameras, hearing aids, notebook computers - almost everything in use today contains flexible circuits.
