Advantages and characteristics of wiring
● small size and light weight, the wiring board was originally designed to replace the wire harness wires with larger size. On the current assembly boards for cutting-edge electronics, wiring is often the only solution to meet the requirements for miniaturization and mobility. Wiring (sometimes called flexible printed wiring) is the etching of copper circuits on a polymer substrate or the printing of polymer thick-film circuits. Design solutions for thin, lightweight, compact and complex devices range from single-sided conducting circuits to complex, multilayer, three-dimensional assemblies. The total weight and volume of wire arrangement is 70% less than that of traditional circular wire harnesses. The wiring may also be strengthened by the use of reinforcing materials or liners to obtain additional mechanical stability.
● the wiring can be moved, bent and twisted without damaging the wires, and can conform to different shapes and special package sizes. The only limitation is volume space. With the ability to withstand millions of dynamic bends, the alignment is well suited for continuous or periodic motion in inline systems as part of the final product’s functionality. Solder joints on rigid PCB will fail after hundreds of cycles due to thermal mechanical stress. Jenny, product manager at EECX, says that certain products that require electrical signal/power movement and have a smaller shape factor/package size benefit from wiring.
● excellent electrical properties, dielectric properties and heat resistance. The low dielectric constant allows for fast transmission of electrical signals, says LT Electronic’s chief executive. Good thermal performance makes the element easy to cool down; A higher glass conversion temperature or melting point allows the element to operate well at higher temperatures.
● with higher assembly reliability and quality. Wiring reduces the amount of hardware required for wiring, such as solder joints, trunk lines, floor lines, and cables commonly used in traditional electronic packaging, enabling wiring to provide higher assembly reliability and quality. Because of the complex multiple systems composed of the traditional connected hardware in the assembly, it is easy to appear a high component dislocation rate. Ping. Wu, marketing manager of EECX Electronic Products Division, said: the rigidity of the wiring is low and the volume is small. With the advent of quality engineering, a very thin flexible system was designed to be assembled in only one way, eliminating many of the human errors commonly associated with stand-alone wiring projects.
Application and evaluation of alignment
The use of wiring is increasing dramatically. PING, the general manager, said: “almost when you pick up any piece of electrical equipment today, you will find wiring in it. Turn on a 35mm camera and there are 9 to 14 different lines in it, because cameras are getting smaller and more versatile. The only way to reduce volume is to have smaller components, finer lines, tighter pitch, and flexible objects. Pacemakers, medical devices, video cameras, hearing AIDS, portable computers — almost everything we use today has wires in it.
