What is a flat cable? What are the characteristics of cables?

For sensitive women, some mechanical and electronic products have always been rice paste. I don't even know what that is. For example, cables. Many people know that there are wave lines in decorating houses, and different wires are needed to install circuits. So what exactly is a flat cable? What are the characteristics of cables? For sensitive women, some mechanical and electronic products have always been rice paste. I don't even know what that is. For example, cables. Many people know that there are wave lines in decorating houses, and different wires are needed to install circuits. But I feel that telegrams have never been heard of. So, what is a flat cable? What are the characteristics of cables?

What is a flat cable?

Flat cable, also known as flexible printed circuit board (FPC). Used for data transmission in moving parts and moving areas according to the rules, sequence, color and quantity of cables in the industry. For example, the data cable between the computer motherboard and the hard disk and CD-ROM drive, the data cable between the mobile phone motherboard and the display screen, and the data cable between connecting devices are all collectively called flat cables.

What are the characteristics of cables?

1. Flat cable is small in size and light in weight. Flat cable boards were originally designed to replace bulky wire harnesses. In the current sophisticated electronic equipment assembly board, cable arrangement is usually a solution to meet the requirements of miniaturization and mobility. Flat cables (sometimes called flexible printed circuits) are etched copper circuits or polymer thick film circuits printed on polymer substrates. For compact and complex thin devices, the design scheme ranges from single-sided conductor to complex multi-layer three-dimensional assembly. Compared with the traditional circular wire harness method, the total weight and volume of flat cable are reduced by 70%. The strength of the flat cable can also be increased by using reinforcing materials or linings to obtain additional mechanical stability.

2. Flat cables can move, bend and twist without damaging wires, and can conform to different shapes and special packaging sizes. Its only limitations are volume and space. Because it can withstand millions of times of dynamic bending, flat cable can be well applied to continuous motion or periodic motion interconnection system and become a part of the final product function. Solder joints on rigid PCB will fail after hundreds of cycles under the action of thermo-mechanical stress. Jenny, product manager of EECX, said, "The electrical signal/power supply needs to be moved, and some products with small form factor/package size benefit from cable arrangement."

3. The flat cable has excellent electrical performance, dielectric performance and heat resistance. The CEO of LTElectronic said: "The low dielectric constant allows fast transmission of electrical signals; Good thermal performance makes the element easy to cool; Higher glass transition temperature or melting point makes the element work well at higher temperature. "

4. The flat cable has higher assembly reliability and quality. The flat cable reduces the hardware required for interconnection, such as solder joints, trunk lines, backplane wires and cables commonly used in traditional electronic packaging, so that the flat cable can provide higher assembly reliability and quality. Because the traditional interconnection hardware composed of complex multi-systems is prone to high component dislocation rate during assembly. The flat cable has low rigidity and small volume, and it is precisely because of the small volume of the flat cable board assembly that less materials are used. With the emergence of quality engineering, thin flexible systems are designed to be assembled in only one way, thus eliminating many human errors usually associated with independent wiring engineering.

What is a flat cable? What are the characteristics of cables? There's an answer on it. In fact, mobile phones, computers and mice all have cables. The cable itself has the characteristics of small volume and free movement. If you move and twist the thread casually, it won't break easily. Of course, if people find that there is something wrong with the cable at this time, don't open it without authorization.
