New Opportunities for the Development of Surface Treatment Industry from LED Electroplating

With the deterioration of the earth's environment and the continuous strengthening of people's low-carbon and environmental awareness, LED products have gradually been widely used in our lives with their unique characteristics of no flicker, no ultraviolet radiation, no electromagnetic wave radiation, and low thermal radiation. It has also led to a new leap in LED electroplating in the surface treatment industry, especially in the field of LED bracket electroplating, which has become the "meat on the plate" that many industry professionals are scrambling for. When it comes to LED electroplating, some people who don't know much about the industry will definitely ask what LED is, what the specific LED electroplating process is, and how much new profit it can bring to our industry. Next, the editor will slowly answer for you.

What is LED?

LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin. The semiconductor chip consists of two parts, one is a P-type [1] semiconductor, in which holes dominate, and the other end is an N-type semiconductor, which is mainly electrons. But when these two semiconductors are connected, a "PN junction" is formed between them. When current passes through the wire to act on the chip, electrons will be pushed to the P region, where electrons and holes recombine and then emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light determines the color of the light, which is determined by the bandgap width of the material that forms the PN junction. The 2.5-meter-wide endurance board has been successfully installed and debugged by Zhengcheng Enterprise! Greatly improved the lighting effect.

What is LED bracket electroplating?

LED bracket, the base of LED lamp bead before packaging. On the basis of LED bracket, fix the chip into it, weld the positive and negative electrodes, and then use silicone resin to package it once. LED bracket is generally made of copper, because copper has good conductivity. It has leads inside to connect the electrodes inside the LED lamp bead. After the LED lamp bead is packaged, the lamp bead can be removed from the bracket. The copper feet at both ends of the lamp bead become the positive and negative electrodes of the lamp bead, which are used to weld to LED lamps or other LED finished products. Due to its high technical content, LED bracket electroplating has attracted more and more attention from industry insiders.

What are the main applications of LED?

In view of the advantages of LED itself, it is currently mainly used in the following aspects:

(1) Application of display screens and traffic signal display light sources LED lights have the characteristics of earthquake resistance, impact resistance, fast light response speed, power saving and long life. They are widely used in various indoor and outdoor display screens. They are divided into full-color, three-color and monochrome display screens. There are more than 100 units in the country developing and producing them. Traffic lights mainly use ultra-high brightness red, green and yellow LEDs. Because the use of LED signal lights is both energy-saving and highly reliable, traffic lights are gradually being updated nationwide, and the promotion speed is fast. The market demand is huge, which is a good market opportunity.

(2) Application in the automotive industry Automotive lighting includes the dashboard, audio indicator lights, switch backlights, reading lights, and external brake lights, taillights, side lights, and headlights. Incandescent lamps for automobiles are not resistant to vibration and impact, are easily damaged, have a short lifespan, and need to be replaced frequently. In 1987, my country began to install high-mounted brake lights on cars. Due to the fast response speed of LEDs, they can remind drivers to brake early and reduce rear-end collisions. In developed countries, central rear high-mounted brake lights made of LEDs have become standard parts for cars. In 1996, the American HP company launched an LED car taillight module with three colors of LED lights, which can be combined into various car taillights at will. In addition, the light source of the dashboard and other lighting parts of the car can be served by ultra-high brightness lamps, so they are gradually adopting LED displays. my country's automobile industry is in a period of great development, which is an excellent opportunity to promote ultra-high brightness LEDs. In the next few years, it will generate an annual output value of 1 billion yuan, and in 5 years, it will generate an annual output value of 3 billion yuan.

(3) LED backlight is the most eye-catching with its high-efficiency side-emitting backlight. As an LCD backlight, LED has the characteristics of long life, high luminous efficiency, no interference and high cost performance. It has been widely used in electronic watches, mobile phones, BP machines, electronic calculators and card readers. As portable electronic products become increasingly miniaturized, LED backlight has more advantages. Therefore, the backlight manufacturing technology will develop towards thinner, low power consumption and uniformity. LED is a key component of mobile phones. An ordinary mobile phone or PHS needs about 10 LED components, while a color screen and camera mobile phone needs about 20 LED components. At present, the consumption of mobile phone backlight is very large, with 3.5 billion LED chips used per year. At present, my country's mobile phone production is very large, and most LED backlight sources are imported. This is an excellent market opportunity for domestic LED products.

(4) Early LED lighting sources had low luminous efficiency, and the light intensity could only reach a few to dozens of mcd. They were suitable for indoor occasions and were used in home appliances, instruments, communication equipment, microcomputers and toys. The current direct goal is to replace incandescent lamps and fluorescent lamps with LED light sources. This replacement trend has begun to develop from local application areas. In order to save energy, Japan is planning a light-emitting diode project to replace incandescent lamps (called "Lighting Japan"), with a budget of 5 billion yen for the first five years. If LED replaces half of the incandescent lamps and fluorescent lamps, it can save energy equivalent to 6 billion liters of crude oil each year, which is equivalent to the power generation of five 1.35×106kW nuclear power plants, and can reduce the production of carbon dioxide and other greenhouse gases, improving people's living environment. my country also invested 5 billion in 2004 to vigorously develop energy-saving and environmentally friendly semiconductor lighting plans.

(5) Other applications include a pair of flashing shoes popular with children. The built-in LED will flash when walking. In Wenzhou alone, 500 million LEDs are used each year. LEDs are used as power indicator lights for electric toothbrushes. According to a domestic manufacturer that is currently in production, the company has a small number of health toothbrushes on the market. It is estimated that 300 million LEDs will be needed each year for mass production. The popular LED Christmas lights have a novel shape, rich colors, are not easy to break, and are safe to use at low voltage. They have recently been selling strongly in Hong Kong and other Southeast Asian regions and are widely welcomed by people. They are threatening and replacing the existing Christmas market for electric light bulbs.

LED flash can not do without electroplating process

(6) LED products for home interior lighting are becoming more and more popular. LED downlights, LED ceiling lights, LED fluorescent lamps, and LED fiber optic lamps have quietly entered households!

New opportunities brought by LED to the surface treatment industry

With the rapid development of the LED raw material market, surface mount devices have been available since 2001, mainly used in indoor full-color screens. With its high brightness, bright colors, low temperature, and adjustable dot spacing, it has been accepted by demanders at different price points. In just over two years, product sales have exceeded 300 million yuan, and the surface mount full-color LED display application market has entered the new century. In order to adapt to the "slimming" plan of the 2008 Olympic Games, Leyard has developed a surface mount dual-primary color display, which is widely used in training halls and competition timing and scoring systems. In terms of full-color screens in Olympic venues, in order to tighten investment, most of the full-color screens are detachable. They can be used as live broadcast tools during the Olympics, and can be used for rental after the event. They can be used as performances, national policy releases and other public application tools, so that costs can be recovered as soon as possible.

As far as the market is concerned, China's entry into the WTO and Beijing's successful bid for the Olympic Games have become new opportunities for the development of the LED display industry. The domestic LED display market has maintained sustained growth. At present, the market share of domestic LED displays in the domestic market is nearly 95%. The international market capacity of LED displays is expected to grow at a rate of 30% per year.

According to the editor, the most authoritative company in China for LED electroplating, including LED bracket electroplating, is Shenzhen Aomitech Technology Co., Ltd. Aomitech is the first company in China to enter the field of LED bracket electroplating. The company's technical personnel have more than 30 years of rich experience in the industry.
