Printed Circuit Board Overview

PCB has a wide range of applications, almost all electronic equipment has to use PCB as the carrier. Therefore, there are many kinds of PCBs, different standards have

different classification method. Such as according to the number of

layers can be divided into double-sided printed board, multi-layer

printed board, according to the properties of base material can be

divided into rigid printed boards, flexible printed boards, rigid-flex

printed boards, can also be divided into high-frequency microwave

printed boards, HDI printed boards, blind buried hole printed boards,

embedded components printed boards, etc according to the scope of

application or structural particularity.

Currently, there are more than 3,800 PCB manufacturing companies around the world. Among

them, China's PCB enterprises, including Taiwan, about 1800, accounting

for 47% of the world's, the output value accounting more than 90% of

the Global. In addition, there are a large number of companies related to the PCB industry in China. Such as

PCB materials Enterprises, PCB dedicated equipment enterprise and

agents, PCB manufacturing enterprises are closely linked with these

enterprises.

Many well-known world PCB enterprise's production bases have begun to develop in China. For example, the Austrian technology and Systems Technology Corporation (AT&S) established a Chinese company in Shanghai in 2001, established a more productive branch in Chongqing in2011. As a result

of the rapid improvement of electronic products technology, the original

supply chain structure has also changed because of the rise of the

price war. China has considerable advantages in terms of industrial

distribution, input costs and market integration.

Trend

It can be expected that the production investment and transfer of the world PCB Enterprises will take China as its destination for a long time. As a result, China is already one of the world's most important PCB production sites.

In the past more than 10 years, China's PCB manufacturing industry has developed rapidly, the types of printed circuit boards are also in constant development. Printed circuit boards have evolved from the original single-layer circuit board to multilayer printed circuit boards, flexible circuit boards, rigid and flexible circuit boards, and some special circuit boards with specific functions.

Due

to the rapid development of electronic products to high frequency and

high speed, the future development trend of the printed circuit board

technology should be closer to high precision, high density, and high

performance. And reducing the size of PCB and cost will also be a

profitable strategy for PCB enterprises to occupy the market.
