4-Layer Rigid-Flex PCB Manufacturers

IC refers to integrated circuits, which are made on semiconductors because semiconductors are the most suitable materials for realizing transistors, and transistors are the core devices of most circuits now. However, I want to write more here, tracing back to the origin, starting from the beginning of "circuit"

Due to the continuous introduction of thin, light and short products in the market, the high-function, high-speed and other double-height era has been developed, and the trend of high-frequency, high-speed, and multi-IO chips has been developed.

PCB (Printed Circuit Board) is an industry with a relatively low technical threshold. However, 5G communication has the characteristics of high frequency and high speed. Therefore, 5G PCB requires higher technology and the industry threshold is raised; at the same time, the output value is also pulled up.

In a certain period of time, enterprises will encounter the bottleneck of development. The operating cost has been rising, but it is difficult to find the "location" of the cost. We call it "invisible cost". 1. Meeting cost

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

Why does the resistivity of semiconductor go down with temperature？Between the conductor and semiconductor resistivity difference is due to the different density of charge carriers.
