Section 1 definition of PCB potion
PCB (PrintedCircuitBoard), Chinese name called printed circuit board, also known as the printed circuit board, printed circuit board, is an important electronic components, electronic components to support the body, the provider of the electrical connection in the electronic components.Because it is made of electronic printing, it is called “printed” circuit board.The PCB board has the following three main types of classification:
PCBS refer to chemical products used in PCB manufacturing.Copper plate, copper foil, semi-curing tablets, chemical potion, anode copper/tin/nickel, dry film, ink and other products are the main raw materials needed for PCB production.
Section two development of PCB medicine industry
The inventor of the printed circuit board was Austrian Paul esler, who used a printed circuit board in a radio installation in 1936.In 1943, americans used the technology heavily on military radios.In 1948, the United States officially recognized the invention for commercial use.Since the mid-1950s, the printing circuit has been widely used.
Before the printed circuit board appeared, the interconnection between electronic components was realized by direct wires.Now, the circuit panel is only available as an effective experimental tool;Printed circuit boards have dominated the electronics industry.
With the invention of printed circuit board, PCB potion also came into being.
Rigorous and scientific research methods can ensure the accuracy and quality of research reports.Potion “2012-2016 China PCB industry research depth and investment value study report” mainly adopts the research methods are: 1) census: we PCB potion nearly hundred practitioners in the industry for the interview or telephone access, get the best data.2) tracking research: in order to ensure the real-time dynamic potions master PCB industry, we have established tracking the potion in the PCB industry mechanism, and by accessing each month for PCB potions industry development.3) government agency data: we have inquired about the industrial and commercial files of key enterprises in PCB medicine industry, statistics bureau records, customs import and export data, etc., and obtained more authoritative information.4) SOWT analysis: using SWOT analysis and porter’s five forces analysis, we analyzed the competitive advantages and potential threats and development opportunities of PCB potion industry and enterprises.5) scientific prediction: we use regression analysis, time series analysis, factor analysis, combinatorial analysis and other methods to make a full forecast of the development trend of PCB potion.
