Printed circuit boards are closely related to the development of integrated circuits When it comes to integrated circuits, you have to make a printed circuit board. Printed circuit board is the key interconnect for assembling electronic parts, not only providing electrical connection for electronic components, but also carrying electronic equipment digital and analog signal transmission, power supply and RF microwave signal transmitting and receiving business functions, the vast majority of electronic equipment and products need to be equipped. Popular speaking, if the integrated circuit is a first-class package, all the whole machine including mobile phones, computers, televisions, cameras and other electronic products are three-class packaging, then printed circuit board is the two-level package, play a connecting link and irreplaceable key role.
Therefore, the printed circuit board and the development of integrated circuits are closely related.
Domestic printed circuit board emerging, precious metal electroplating materials play a key role Professor Sun Jianjun, chairman of the 12th session of electroplating Expert committee, said that since 2006, China's printed circuit industry, including copper clad laminate, raw and auxiliary materials and special equipment production, production value has reached the world's first, the global market share in 2016 climbed to 50.04%, China has become one of the few countries in the world that can provide the largest production capacity and the most complete product type of printed circuit boards.
At the same time, in high-end multilayer board, flexible board, HDI board and other high-end printed circuit board areas have a place, such as Shantou ultrasound, which is a professional production of double-sided, multi-layer, high and high-density arbitrary interconnection printed circuit board company, the company's current products have been sold in North America, Europe, Singapore and other countries and regions. The development of printed circuit board can not be separated from the precious metal electroplating materials, that is because the printed circuit board of electronic components for stability, conductivity, toughness, ductility, and so there are very high requirements, and only precious metal electroplating materials to meet these requirements. Domestic printed circuit board manufacturing can occupy the global market more than 50% of the share, inseparable from the precious metal electroplating materials domestic credit. At present, the domestic precious metal electroplating material production enterprises have nearly 30, the main production enterprises, including Yantai recruit King Fo Precious Metals Co., Ltd., Suzhou Xing Rui Precious Metal Materials Co., Ltd, Jiangsu Sudate Chemical Reagent Co., Ltd. and Shenzhen Fu Chun Materials Technology Co., Ltd. One recruit King Fo the company's precious metals electroplating material products are mainly gold potassium cyanide (commonly known as gold salt), silver potassium cyanide/silver cyanide (commonly known as silver salt). Gold salts as the main material of gold-plated, by virtue of corrosion resistance, abrasion resistance, low contact resistance and other excellent performance is widely used in printed circuit boards, connectors, semiconductor devices and other electronic information industry;
Silver Salt, as the main material of electroplating silver, is widely used in electrical contact materials in electric and electronic industry by virtue of excellent conductivity and brazing performance. In fact, the precious metal electroplating material is not only the key material of PCB manufacture, chip is also the realization of outstanding performance of important materials, such as the chip connected to the use of pins, lead frame is almost silver coating, and chip electrode materials, integrated circuit board conductor coating, led light-emitting chips are also required through gold, platinum,
Silver and other precious metal electroplating materials for electroplating process treatment.
The development of integrated circuit industry has risen to the national strategic level, the basic materials become the key
Integrated circuit industry is the strategic, basic and leading industry of national economy and social development, is the core and foundation of cultivating and developing strategic emerging industries, promoting the integration of informatization and industrialization, and is the important support of adjusting economic development mode, adjusting industrial structure and guaranteeing national information security. The development of the domestic printed circuit board industry gives us a revelation, that is, any industrial development needs to start from the Foundation, master key basic materials production is essential.
Integrated circuit manufacturing as a technology, capital, talent are highly dependent on the industry, want to achieve large development, the same must be from the basic materials. China | ' Core ' | To start with the basic material
