PCB Is An Important Electronic Component

- Jun 08, 2017-

PCB (Printed Circuit Board), the Chinese name for the printed circuit board, also known as printed circuit board, is an important electronic components, is the support of electronic components, PCB electronic components is the carrier of electrical connections. Because it is made using electronic printing, it is called "printed" circuit board.

PCB using printed circuit board, due to the consistency of the same printed circuit board, thus avoiding the error of manual wiring, and electronic components can be automatically inserted or installed, PCB automatic solder, automatic detection to ensure the quality of electronic equipment, Increased labor productivity, reduced costs, and easy maintenance.

In the high-speed update of technology products iterative today, people on the electronic components of the scientific and technological content and quality requirements are constantly high-end. PCB to enhance the comprehensive competitiveness of enterprises, and promote the market, the prosperity and development of the economy, have played a crucial role. But in the PCB mining chain has a variety of drawbacks.

In the PCB procurement process, from the procurement, logistics, capital delivery, PCB to the final agreement between the two sides, each link can not be ignored. Supply chain system in order to achieve a real closed-loop, it is necessary to achieve four-in-one: information flow, business flow, logistics, capital flow is indispensable, PCB but to achieve this goal, with greater difficulty in achieving.

Look at the market, in the PCB industry, manufacturing costs accounted for 45%, PCB circulation value accounted for 55% (of which 35% purchase + sales 5% + logistics 3% + inventory or capacity idle 12%).

In the "PCB + Internet" era for the majority of PCB small and medium enterprises solemnly build electronic materials trading platform. Through the platform, customers can purchase high-quality electronic materials, you can also each circuit board factory inventory information provided to the various manufacturers. So that inventory material turnover up, so that enterprises need to buy raw materials in a timely manner to produce the necessary materials. As a result, a substantial increase in the supply of sheet metal, PCB balance with the upstream supply manufacturers trading relationship.

Green solder resist ink is the oldest and most expensive and most popular.

Blue and black are mixed with cobalt and carbon, with a certain conductivity, so there is the risk of short circuit, green PCB more environmentally friendly, high temperature environment will not use when the release of toxic gases.

From the beginning of 2007, people began to pay attention to the color of the PCB board, mainly because many first-tier manufacturers of high-end panels are used in the green PCB board color design, so people slowly think that the PCB color is green must be High end.
