What is PCB?
PCB (Printed Circuit Board), abbreviated as printed board, is one of the important components in the electronics industry.
Almost every electronic device, from electronic watches and calculators to computers, communication electronic equipment, military weapon systems, as long as there are integrated circuits and other electronic components, for the electrical interconnection between them, printed boards are used.
In the research process of larger electronic products, the most basic success factor is the design, documentation and manufacturing of the printed board of the product. The design and manufacturing quality of printed boards directly affect the quality and cost of the entire product, and even lead to the success or failure of commercial competition.
The role of PCB
After the electronic equipment adopts the printed board, due to the consistency of the similar printed boards, the error of manual wiring is avoided, and the automatic insertion or placement of electronic components, automatic soldering, and automatic detection can be realized to ensure the quality of the electronic equipment , Improve labor productivity, reduce costs, and facilitate maintenance.
Printed boards have evolved from single-layer to double-sided, multi-layer and flexible, and still maintain their respective development trends. Due to the continuous development in the direction of high precision, high density and high reliability, the continuous reduction of volume, cost and performance have made printed boards still maintain a strong vitality in the future development of electronic equipment.
The domestic and international discussions on the future development trend of printed board manufacturing technology are basically the same, that is, high density, high precision, small aperture, thin wire, fine pitch, high reliability, multiple layers, high speed transmission, light weight, The development of thin type, in the production at the same time, to increase productivity, reduce costs, reduce pollution, adapt to the development of multi-variety, small batch production direction. The technological development level of the printed circuit is generally represented by the line width, aperture, board thickness/aperture ratio on the printed board.
In recent years, the consumer electronics market, led by mobile electronic devices such as smart phones and tablet computers, has grown rapidly, and the trend toward smaller, lighter and thinner devices has become increasingly apparent.
As a result, traditional PCBs can no longer meet the requirements of products. For this reason, major manufacturers have begun to research new technologies to replace PCBs. Among them, FPC as the most popular technology is becoming the main connection of electronic equipment Accessories.
In addition, the rapid rise of the emerging consumer electronics market such as wearable smart devices and drones has also brought new growth space for FPC products. At the same time, the trend of display and touch control of various electronic products has enabled FPC to enter a wider application space with the help of small and medium-sized LCD screens and touch screens, and the market demand is increasing.
