PCB Technical - FPC circuit board green advocacy and characteristics

PCB circuit boards live in the current society and are advocated by the government for advocating green. Energy saving and environmental protection are equally important, while improving energy efficiency and vigorously protecting

Environment, effectively solving environmental problems, this is an important issue of the global energy development strategy.

At present, most of the advanced treatment of circuit board wastewater in China only achieves sand filtration and discharge. According to the results of multiple commissioning and investigations in the wastewater treatment facilities of larger circuit board factories in the Pearl River Delta, the copper in the water is precipitated after the above treatments. The ion concentration is generally about 1.5mg/L. After filtration, the copper ions in the effluent still cannot meet the standard.

Therefore, in-depth treatment must be carried out. The advanced treatment process is generally: activated carbon adsorption and cation exchange after sand filtration. The water used on the circuit board industrial production line is generally divided into three types: pure water, soft water, and general tap water. Sewage treated by the above process can generally be used as cleaning water, and can also be used for watering roads, greening, washing toilets and other purposes.

For the small amount of circuit board wastewater, there is a simple and convenient treatment method. It is generally difficult to discharge wastewater with a small amount of wastewater. At this time, Na2S can generally be used as a heavy metal ion remover, and a simple sewage treatment process of coagulation, reaction, precipitation, and filtration is adopted. However, there is a problem of secondary pollution caused by excessive addition of Na2S.

The so-called fpc refers to the abbreviation of flexible printed circuit. In life, it is also called flexible circuit board, flexible circuit board and flexible printed circuit board, so it is referred to as fpc or soft board. Maybe in this industry, everyone knows some of fpc Features, for example, fpc circuit boards have the characteristics of light weight, high wiring density and thin thickness.

So now that you know its characteristics, where can it be used, let's introduce the use range of fpc and the knowledge of fpc cable.

Fpc is mainly used in 3C digital products, such as mobile phones, handheld computers, notebook computers, digital cameras, lcm and other products.

FPC flexible printed circuit board, which is made of polyimide or polyester film as a base material with high reliability and excellent flexibility.

What are the characteristics of fpc circuit boards?

First, it can be freely bent, folded, and wound, and can be moved and stretched freely in three-dimensional space.

Second, the heat dissipation performance is good, and the F-PC can be used to reduce the volume.

Third, it can achieve lightweight, miniaturization, and thinning, so as to achieve the integration of component devices and wire connections.
