基板的英文怎么说？

A PCB (Printed Circuit Board) is an important component of most modern electronic devices. It is composed of two or more layers of copper-clad laminated sheets which are chemically treated to form a substrate. This substrate is then etched to create the electrical connections between components.

The PCB has become an integral part of all electronic products, ranging from the simplest circuit to the most complex one. PCBs can be made with a variety of materials such as rigid, flexible, and multi-layer constructions. They are further modified by the addition of plated gold, soldering, and other finishing techniques. The combination of these multi-layer constructions allow the PCB to effectively interconnect electronic components and to securely house them.

The modern PCB is more complex than ever before and can be used to design a variety of components such as capacitors, resistors, diodes, and transistors. These components can be integrated in to a board by various manufacturing processes including laser cutting, laser drilling, etching and soldering.

The use of a PCB provides several benefits to electrical engineers. They can create a circuit design with components that can be connected quickly and easily, and the process takes less time than if the components were connected using traditional wiring methods. It also reduces the risk of electrical failure as the components are each isolated and clearly labelled for easy identification.

In addition to its usage in electronics, the PCB is also used in medical and aerospace applications. Due to its strong construction and ability to provide clean electrical pathways, the PCB can withstanding extreme temperatures and conditions.

The PCB is an essential component of electronics and is used in a variety of applications. Its use in both the commercial and industrial markets provide versatility and convenience. It offers efficiency, cost savings and increased performance. The PCB is the backbone of modern electronics and will continue to be used as technology improves.
