What does optical fiber mean? Optical fiber is a kind of slender flexible glass or plastic fiber used to transmit optical signals, which is usually used to transmit high-speed data and communication signals over a long distance. The core of optical fiber is surrounded by materials with high refractive index and covered by materials with low refractive index. This design allows light to propagate inside the core with almost no optical loss, so that optical signals can be transmitted over a long distance without obvious signal attenuation. Optical fiber has become one of the most important technologies in modern communication field, which is widely used in telephone, Internet, television and computer network.In order to facilitate users to have a better experience, fiber optic patch cord Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. https://www.fibercan-network.com/

　　In optical fiber, optical signal is converted into optical pulse and propagates along the core, which enables the signal to be transmitted over a long distance without obvious signal attenuation. Here are some basics of getting started with optical fiber:

　　Optical fiber structure: Optical fiber is mainly composed of core, cladding and sheath. The core is the core of optical signal transmission, usually made of glass or plastic with high refractive index. The cladding is surrounded by low refractive index material to protect and guide light, and the sheath is used to protect the optical fiber and enhance its strength.

　　Working principle of optical fiber: When light enters from a medium with high refractive index into a medium with low refractive index, the light will be totally reflected. The refractive index of the core material of optical fiber is higher than that of the cladding material, which makes the light can be totally reflected in the core for many times, thus realizing signal transmission.

　　Optical fiber type: Common optical fiber types include single-mode optical fiber and multimode optical fiber. Single-mode fiber has small core diameter and high refractive index, which is suitable for long-distance and high-speed transmission. The core diameter of multimode fiber is large, which is suitable for short-distance transmission.

　　Optical fiber application: Optical fiber has become one of the most important technologies in modern communication field, which is widely used in telephone, Internet, television and computer network. It is also widely used in medical, military, aerospace and scientific research fields.

　　Advantages of optical fiber: Compared with traditional copper cable, optical fiber has higher bandwidth, lower signal attenuation and smaller signal delay. In addition, the signal of optical fiber is not easy to be eavesdropped or interfered, so it has higher security.

　　As the mother of electronic components, circuit board plays an important role in electronic applications. According to different design principles, circuit boards can be divided into single panel, multilayer board, soft board, hard board, soft-hard board and so on.among pcb assembly manufacturer It has given great spiritual support to entrepreneurs, and more entrepreneurs will contribute to this industry in the future. https://intechcircuit.com/

　　At present, the common PCB colors on the market are green, black, blue, yellow, purple, red and brown, and white and pink PCBs have appeared recently.

　　So, why do PCB boards have different colors? Have you found that most of the circuit boards are green, but other colors are rare? Why? Next, Shenzhen Lianxiaobian will give you a wave of knowledge about circuit boards ~

　　Why do PCBs have different colors?

　　In the production process of PCB, the final surface of copper layer is smooth and unprotected, whether by additive process or reduction method. Although the chemical properties of copper are not as easy to oxidize as pure copper of aluminum, iron and magnesium in contact with oxygen in water, the thickness of copper layer in PCB circuit board is very thin, and the oxidized copper will become a poor conductor of electricity, which will greatly damage the electrical performance of the whole PCB. In order to prevent copper oxidation, separate the soldered part from the non-soldered part of PCB and protect the surface of PCB, the design engineer will apply a special coating on the surface of PCB to form a protective layer with a certain thickness to block the contact between copper and air. This coating is called solder resist and the material used is solder resist paint. In order to facilitate maintenance and manufacturing, PCB usually needs to print small text on the board. Therefore, engineers added various colors to the solder resist paint, and finally formed a “colorful” circuit board.

　　Why are green inks widely used?

　　The color of solder resist mainly depends on the color of solder resist ink. Green ink is the most widely used and the cheapest in the market. In fact, the solder resist ink on the market is not limited to one kind of green, and there are many colors such as red, blue, purple, black and yellow, but green is the most common one. The main reason is that the use of green solder resist ink has the following advantages: it is convenient for optical positioning correction.

　　The manufacturing process of the circuit board itself includes STM welding process, and this process needs to be tinned and finally verified by AOI. These processes need to be calibrated by optical positioning, and the green background color has a better recognition effect for the instrument. In the yellow room, the visual effect is better. The whole PCB product has to go through the processes of board making and SMT in the production process. Usually, when the circuit board is used in the production and processing of electronic products, there will be some processes that need to pass through the yellow room. According to the optical law, the green circuit board has a better visual effect in the yellow room, and it is easier to check the production of electronic products.

　　It is beneficial for workers to observe the circuit board.

　　At present, due to the production process and other problems, the quality inspection process of many lines still depends on the naked eye observation and identification of workers (of course, flying needle testing technology is mostly used at present). It is very tiring to keep staring at the board under strong light. Using green as the background color of circuit board can reduce the damage of strong light to workers’ eyes, so most manufacturers in the market use green PCB at present.

　　Environmental protection and low cost.

　　Because the circuit board needs to be recycled at high temperature when it is discarded, and the green solder resist ink will not release toxic gases, recycling is more environmentally friendly. Thanks to the above advantages, the adoption rate of green solder resist ink is the highest and the production process is the most mature. Therefore, the cost of using green solder resist ink to produce circuit boards is also lower.

　　”Big bags, small bags, please go through security check!” Security check is always an essential step when you travel by high-speed rail, airplane, or subway. I wonder if you have ever been interested in this security check machine. What can the staff see on the screen? How do they quickly identify the items in the suitcase? Today, let the editor reveal this secret for you.As can be seen from the new data, baggage scanner machines The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://secuzoan.com/

　　How does the security inspection machine work?

　　Generally speaking, the machine that conveys and inspects luggage is called an X-ray luggage inspection machine. As the name suggests, the security inspection machine uses X-rays to inspect luggage.

　　X-rays are short-wavelength electromagnetic waves that can penetrate objects. The penetration of X-rays varies depending on the thickness, density and material of the object.

　　Everyone should know that X-rays in hospitals are also used by doctors. The penetration rate of X-rays varies according to the density of the structure and tissue. The penetration rate is high in loose areas and low in dense areas. The bones of the human body are denser than the skin and flesh tissue. Therefore, when X-rays are irradiated to the human body, the outline of the bones will be displayed more clearly on the screen.

　　security check

　　The same is true for the security inspection machine that checks luggage. The penetration rate of X-rays on different objects is different. When the suitcase passes through the security inspection machine, the X-rays penetrate the suitcase and display the outlines of different objects on the display screen.

　　At this time, some friends may feel confused: X-ray imaging should be black and white, so why can security inspectors identify different objects so quickly?

　　This question really hits the nail on the head. If you have ever looked at the security check display screen, you will find that the image on it is in color, not black and white.

　　security check

　　Normally, the color of the image formed by X-rays on the film is indeed black and white, just like the X-ray photos in the hospital. The reason why a color image appears on the security screen is that the computer calculates and converts the projection intensity of the X-rays. This is also to make it easier for security personnel to quickly distinguish different objects in a short period of time.

　　Normally, orange represents organic matter such as liquids and sprays; blue represents metals and various controlled knives; and heavy metals or lead, which can completely absorb X-rays, will be displayed in black.

　　Now you should know why the staff will immediately notice and ask you to take out a small pair of scissors in your suitcase; and the water in your backpack will also be asked to take out and drink a sip.

　　False alarms can undermine the effectiveness of security systems, but wired PIR (Passive Infrared) motion sensors offer a reliable solution. Here¨s how these sensors help minimize false alarms and enhance your security setup.However, with the development of the industry, passive infrared sensor It will also bring us more and more consumer experiences, so that users can really feel the upgrade and change. https://www.sunlit-tech.com
