Printed circuit board production process. Almost every kind of electronic equipment, from electronic watches, calculators, to computers, communication electronic equipment, military weapon systems, as long as there are electronic components such as integrated circuits, they must be printed with pcb for electrical interconnection between them PCB, pcb circuit board is the carrier of electronic components! [...]
In the process of producing printed circuit boards, a large amount of waste water is generated, and the pollutant composition is complex, which is harmful to the environment. Among them, it contains a large amount of heavy metal ions and toxic substances. If not handled properly, it will cause serious harm. Studies have shown that [...]
Towards higher density and lighter In recent years, the focus of the printed circuit board (PCB) market has shifted from computers to communications. In the past two years, it has shifted to mobile terminals such as smart phones and tablet computers. Therefore, HDI boards for mobile terminals are the main point of PCB growth. Mobile [...]

Generally speaking, users will focus on their professionalism when choosing a PCB circuit board design manufacturer, and believe that the quality of highly professional products is guaranteed. So what qualifications should a professional PCB circuit board design manufacturer have? On the one hand, whether it has strong "hard power", mainly refers to the advanced nature [...]
The color of the PCB surface is actually the color of the solder resist. Solder resist one is to prevent the occurrence of wrong soldering of components, The second is to delay the service life of the device and prevent oxidation and corrosion of the device circuit. If you know more about electronic products, you [...]
FPC, also known as flexible printed circuit board, is a printed circuit made of flexible insulating substrates (polyester film or polyimide). It has many advantages that printed circuit boards do not have. FPC flexible circuit boards can not only bend freely, but also Folding and winding, it also has the characteristics of light weight, small [...]

Classification of road boards According to the number of layers, there are three types of single-sided, double-sided, and multilayer circuit boards, according to the circuit layers inside. The first is a single-sided circuit board. On a general circuit board, the components are on one side of the board, and the circuit is on the other [...]
