Line array, also known as flexible printed line, is a copper wire or polymer thick film power supply circuit made on the polymer surface or part of the surface according to etching process or surface packaging printing. Computer cables improve their characteristics on the basis of adding raw materials.

It has the characteristics of expanding compressive strength and improving the reliability of mechanical equipment. Computer cable can be bent, moved and twisted, which is not easy to damage the transmission line and can be cut into various specifications; Computer cable has excellent electrical properties, dielectric properties and temperature resistance, which can transmit data and power engineering on a large scale and is not easy to overcome difficulties. The high reliability of computer cable arrangement and high quality of assembly line will make the assembly line easier and more stable.

There are some standards for the application of computer cables. Generally, the opening and closing times of cables reach 8000 ~ 10000 times, and the service time is about 2 years. It is used for the connection of general electronic and electrical parts, and the arrangement of parallel planes is represented by strips instead of the connection route of electronic devices such as wire harnesses, which is beneficial to disassembly. In addition, computer cables must have the minimum specified characteristics of corrosion resistance, corrosion resistance, waterproof, mildew resistance and bacteriostasis.
