PCIe is a standard interface for connecting PC components, such as graphics cards or storage devices, and is used in a wide range of devices, from embedded systems, handheld devices, industrial applications, and servers to supercomputers, etc. For consumers, upgrading the advantage of the later PCIe is that it can support faster memory.

The Printed Circuit Board (PCB) is one of the main parts of all electronic products. The application fields of PCB are quite extensive. Wherever electronic components are used, PCBs are almost always used. Currently, they are mainly used in the fields of information, communication, consumer products, automobiles, aerospace and military, precision instruments and industrial products. They are an indispensable basic part of all electronic products. This article will be divided into several aspects to discuss PCBs, namely type, material, process, installation and welding. Let us have a good understanding of the "mother of the electronics industry" – the PCB.

All electronic products must use the Printed Circuit Board (PCB) to fix the integrated circuit (IC) and other electronic components, and all the integrated circuits and electronic components with different functions are connected with thin copper wires to provide a stable working environment so that electronic signals can circulate between different electronic components.
