We usually refer to metals with good conductivity such as gold, silver, copper, iron, tin and aluminum as conductors. At the same time, materials with poor conductivity, such as coal, artificial crystals, amber, ceramics, etc., are called insulators. Then, we can simply call the material between the conductor and the insulator semiconductor.

PCB proofing, as a component of high-precision electronic products, has been a very common existence in life. However, we all know that domestic professional PCB proofing design needs different point settings in different stages, and large grid points will be used for device layout in the layout stage. Let's take a look at the detailed PCB proofing layout setting skills.

Our common computer boards are basically epoxy resin glass cloth-based double-sided printed circuit boards, one of which is a plug-in component and the other side is a component foot welding surface. It can be seen that the solder joints are very regular. We call it the pad for the discrete soldering surface of the component feet

As we all know, the competition in China's PCB manufacturing industry is very fierce. A complete industrial chain has been formed from a series of processes such as PCB proofing, mass production, packaging and transportation. In recent years, through extensive and rapid development and cruel market competition, the basic pattern of China's PCB industry has been formed. Relevant data show that by 2020, the number of PCB enterprises in Chinese Mainland alone will reach more than 2000, an amazing number.

A semiconductor is a substance with a conductivity between that of a conductor and an insulator. It is not very conductive in a pure state, but its conductivity can be adjusted by adding impurities (doping) or changing the temperature. The typical representative of semiconductors is silicon, which is widely used in the manufacturing of electronic components. Semiconductor technology is the cornerstone of modern electronic devices, such as smartphones, computers, digital cameras, etc., all rely on semiconductor chips. In addition, semiconductors are also very important in the energy field, such as semiconductor materials, which are the core of solar cells
