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

Via hole is also called via hole. In order to meet customer requirements, the via holes must be plugged in the PCB process. Through practice, it has been found that in the process of plugging, if the traditional aluminum sheet plugging process is changed, and the white mesh is used to complete the board surface solder mask and plugging, the PCB production can be stable and the quality is reliable.

There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.

Guo Taiming described its acquisition of Sharp and the introduction of 8K display technology as a replacement for the phoenix. Whether this phoenix can bring Guo Taiming the expected growth and prompt Foxconn to regain the market is still to be verified.

Semiconductor refers to a material whose conductivity can be controlled from insulator to conductor. No matter from the perspective of science and technology or economic development, the importance of semiconductors is very great. Most of today's electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is one of the most influential semiconductor materials in commercial applications.

The term "plug hole" is not a new term for the printed circuit board industry.
