In recent years, with the unfolding of big data and the expansion of technical fields, many seemingly unrelated tasks have become closer and closer. The PCB circuit board industry in the era of big data is also extending to more fields and jobs.

1. The future trend of car electronics and the demand for PCB work

The first is "Requirements and Trends of Car Electronics for Circuit Boards" by Mr. Tan Shaolian. With his rich work experience and keen observation ability, Tan Shaolian proposed that car electronics has always been in the three fields of power, safety and comfort to seek more technological processes that conform to the characteristics of the age. But with the lack of power, climate change and the uncertainties of various factors related to car electronics are shaken. Environmental protection and globalization have become two major trends in the development of car electronics. Under these two major trends, issues such as energy conservation and emission reduction, power recovery, functional integration of related car products, and cost control are involved. Based on how to better comply with the development of these two major trends, Tan Shaolian believes that the following requirements should be imposed on PCB work.

(1) Regarding current requirements, car electronic circuit boards can reach the level of 1.5A/m3 based on the existing technology, but with the use of thick copper technology on circuit boards and in the future, there will be chips embedded in circuit boards. As well as the possibility of selective electroplating, there are also higher requirements regarding the larger extra current.

(2) Regarding voltage requirements, the development of car electronic functions requires a higher additional voltage to match the overall demand development to a certain extent. The circuit board must consider how to dissipate heat under such a large voltage. Therefore, the development of electronic circuit boards for cars in the future may start with more circuit board materials to actively respond to innovative development needs.

(3) Under the technical requirements of the main forced component integration and multi-chip plan, there are also increasingly miniaturized requirements for car electronic components. This requires that the work of the circuit board can be continuously improved to limit the technology of smaller and smaller components to the circuit board in order to meet the development needs of car electronics.

In addition, when talking about the requirements for circuit board suppliers, Tan Shaolian believes that suppliers should understand the impact of the failure mechanism caused by interaction in the supply chain, plan to increase the load capacity of functional parts, and continue to adjust the PCB supply chain to Make efforts with zero mistakes.

2. Changes in manufacturing methods and demand for PCBs under the development of cognitive intelligent accounting

Artificial intelligence has a history of 60 years, and with the emergence of Industry 4.0 and big data, a new generation of intelligent innovation is about to emerge. The manufacturing industry has also changed from the 3.0 industry to the 4.0 industry. In this regard, the guest speaker, Mr. Lu Binyi, gave a speech on "The Opportunities and Challenges of Cognitive Intelligent Accounting for Circuit Boards". Lu Binyi mentioned that because of the changes in manufacturing methods, it requires supercomputers and IT equipment to be smarter and faster to serve humans, and to have more data and intelligent analysis functions. This is to some extent the PCB from The demand for technology and quantity is greater. Therefore, for PCB work, whether it is from the front-end (smartphones, tablets, etc.), the middle-end (routers, base stations, etc.), and even the back-end (supercomputers), they should closely follow the pace of Industry 4.0 and accelerate Development and innovation of related technologies. According to IBM's report on PCB shipments in various countries, it can be seen that my country's PCB shipments are now in the leading position in the middle and low-end products, while the shipments of high-end PCB products are concentrated in Japan, South Korea and other countries. This means that my country's PCB has another way to change from the low-end to high-end products. And this way out is detailed to expand production capacity of hard and soft boards and IC substrates, increase talent training, open up more leisurely business information channels, and PCB social cooperation and interconnection channels. A new height of influence.
