Integrated Circuit Manufacturers

PCB (printed circuit board), whose Chinese name is printed circuit board, is one of the important components in the electronic industry. Almost every kind of electronic equipment, from electronic watches and calculators to computers,

When designing a four-layer PCB circuit board, how is the stack-up generally designed?

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.

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

According to the number of layers, single-sided, double-sided and multilayer circuit boards are divided according to the circuit layer inside.

Printed circuit board (PCB), also known as printed circuit board, is the supplier of electrical connection of electronic components. Its development has a history of more than 100 years. Its design is mainly layout design. The main advantage of using circuit board is that it greatly reduces the wiring and assembly errors, and improves the automation level and production labor rate. According to the number of circuit board layers, it can be divided into single board, double board, four board, six board and other multilayer circuit boards.
