PCB are categorized into three main types: single-sided, double-sided, and multilayer PCB according to the number of layers.
First, there is the single-sided PCB, the most basic PCB, where the parts are concentrated on one side and the wires are concentrated on the other side. Because the wires only appear on one side, the PCB is called a single-sided board. Single-sided PCB are usually simple and inexpensive to produce, but have the disadvantage of not being able to be used in products that are too complex.
Double-sided board is an extension of the single-panel, when a single layer of wiring can not meet the needs of electronic products, the use of double-sided board. Both sides have copper cladding with routing, and can be through the hole to conduct the line between the two layers, so that the formation of the required network connection.
Multilayer board refers to more than three layers of conductive graphics layer and the insulating material between them in order to separate laminates, and the conductive graphics between them according to the requirements of the interconnected printed circuit board. Multilayer circuit boards are electronic information technology to high-speed, multi-functional, high-capacity, small volume, thin, lightweight development of the direction of the product.
Circuit board according to the characteristics of the words are divided into soft board (FPC), hard board (PCB), soft and hard combination of board (FPCB).
PCB (printed circuit board) that is, printed circuit board, referred to as printed circuit board, is one of the important parts of the electronics industry. Almost every electronic device, small to electronic watches, calculators, large to computers, communications electronics, military weapons systems, as long as there are integrated circuits and other electronic components, in order to make the electrical interconnections between the various components, are to use the printed circuit board. Printed circuit board by the insulating substrate, connecting wires and assembly welding electronic components of the pad, with a conductive line and insulating substrate of the dual role. It can replace the complex wiring to achieve the electrical connection between the components in the circuit, not only to simplify the assembly of electronic products, welding work, reduce the traditional way of wiring workload, greatly reducing the labor intensity of workers; and reduce the size of the machine, reduce product costs, improve the quality and reliability of electronic equipment. Printed circuit board has a good product consistency, it can be used to standardize the design, is conducive to the realization of mechanization and automation in the production process. At the same time, the whole piece of printed circuit board after assembly and debugging can be used as an independent spare parts, to facilitate the interchange and maintenance of the whole product. At present, the printed circuit board has been extremely widely used in the manufacture of electronic products.
Printed circuit boards were first used in paper-based copper-clad printed circuit boards. Since the emergence of semiconductor transistors in the 1950s, the demand for printed circuit boards has risen sharply. In particular, the rapid development of integrated circuits and their wide application, so that the volume of electronic equipment is getting smaller and smaller, the circuit wiring density and difficulty is getting bigger and bigger, which requires the printed circuit board to be constantly updated. Currently the varieties of printed circuit boards from a single panel to the development of double-sided boards, multi-layer boards and flexible boards; structure and quality has been developed to ultra-high density, miniaturization and high reliability; new design methods, design supplies and board materials, board manufacturing process continues to emerge. In recent years, a variety of computer-aided design (CAD) printed circuit board application software has been popularized and promoted in the industry, in the specialization of the printed circuit board manufacturers, mechanized, automated production has completely replaced the manual operation.
