4K flash builds HD world for you

Abstract: In domestic shopping malls, 4K products are already well known. Through the brewing from 2012 to 2013, a comprehensive "4K" industrial chain covering high-end, cheap, home, commercial and engineering, flat panel and projection, and special splicing applications has been formed. Especially in home malls, 4K TVs are accelerating widely. Driven by the hot sales of 4K TVs, in 2013, for every 10 4K flash devices sold in global malls, 5 were in Chinese malls.

In domestic malls, 4K products are already well known. Through the brewing from 2012 to 2013, a comprehensive "4K" industrial chain covering high-end, cheap, home, commercial and engineering, flat panel and projection, and special splicing applications has been formed. Especially in home malls, 4K TVs are accelerating widely. Driven by the hot sales of 4K TVs, in 2013, for every 10 4K flash devices sold in global malls, 5 were in Chinese malls.

2014 will be the year of widespread 4K flash technology. At the CES 2014, as the world ’s largest consumer electronics and flash accounting equipment exhibition, 4K products have become the most central display content of flash products. This now indicates that 4K has now become "the de facto standard for flash work in the next three years."

Now the words "4K" and "Ultra HD" are not rare in LCD splicing screen malls. Many users know what 4K flash screens are, and which malls are used for 4K Ultra HD LCD splicing screens? Well, in the security surveillance mall, 4K ultra-high-definition LCD splicing screens provide users with a perfect high-definition horizon and enjoy a visual feast.

Of course, many people also think that the high resolution on small standard devices is meaningless. When it reaches a certain level, the naked eye can no longer have the resolution. This is impossible. When the appearance and functional equipment cannot be separated, the screen flashing effect is The best differentiating element, so when people are looking for a better splash screen, they will look for a higher-definition splash screen. The 4K ultra-high-definition LCD splicing screen is also one of the choices for many companies or units that make video terminal flash devices. standard.

4K Ultra HD LCD splicing screen

Large-screen LCD splicing flash system-4K ultra-high-definition LCD splicing screen with built-in 4K * 2K splicing processor, supporting DP signal input and output, with 4 in 1 out 3G-SDI input card, supporting 4K ultra-clear picture, resolution up to 3840 * 2160, with these functions of HDMI1.4 interface, with intelligent source detection and automatic wake-up functions, these are the only in the industry. And Nino's LCD splicing screen supports a full-function interface, accurately monitors more details, and has high reliability and stability.

Which malls are the first 4K UHD applications?

With the launch of each series of products, there will be a shopping mall's personalized processing plan to meet the needs of customers from all walks of life. Then, for the ultra-high-definition monitoring and processing approach, this approach is mainly aimed at safe city applications. Through the organic combination with GIS map data, it handles the key issues such as joint processing, remote situation detection, operation and maintenance of massive monitoring equipment in large-scale video surveillance networks. problem. Therefore, the definition of the picture is very high. The high resolution of 4K3840 * 2160 meets this demand, and has received praise and high attention from the media.

Future mall direction-Ultra HD surveillance processing system

Regarding the ultra-high-definition 4K LCD splicing screen, we not only have a flash screen but also a high-definition monitor, forming an ultra-high-definition monitoring and processing system. This system puts forward a useful monitoring and processing plan for work, and it is primarily targeted It is a large-scale safe city application. Therefore, in the future shopping mall of 4K Ultra HD, the monitoring system of the future security shopping mall will be integrated. Because the large-scale monitoring project cannot be ended by the monitoring system alone, multiple systems such as access control, alarm, and intercom will The integration ends in the same way. Therefore, when user demand is increasing, the cost of a separate deployment control system is too high. Assuming a scalable and scalable monitoring approach, you can save a lot of money. After all, the deployment of big security will end the interconnectivity after all, and it is necessary to end it through a common approach, so the 4K UHD surveillance mall still has a long way to go in the future.

[LED Knowledge] Quality Control of LED Gold Wire Bonding Process

Abstract: The LED chip lead of light-emitting diodes is a gold ball thermosonic bonding process, which uses thermal energy, pressure, and ultrasound to bond the chip electrode and the bonding area on the bracket with AU wires to end the connection of the inner and outer leads operation.

   1. The LED chip leads of light-emitting diodes are made of gold ball thermosonic bonding technology, which uses thermal energy, pressure, and ultrasound to bond the chip electrodes and the bonding area on the bracket with AU wires to end the connection of the inner and outer leads Work .

    2.Technical requirements

2.1 Bonding orientation and solder joint shape requirements

(1) The gold ball of the first bonding point must not have more than 1/4 outside the chip electrode, and cannot touch the boundary between the P-type layer and the N-type layer. As shown in Figure 1, the GaAs single electrode chip wire gold ball Pass and fail comparison pictures.

Figure 1 Orientation criteria for the first bond point

(2) The second solder joint must not exceed the planning of the bracket bonding area, as shown in Figure 2.

火狐截图_2017-05-11T03-12-25.456Z.png

Figure 2 Orientation criteria for the second bond point

(3) The ball diameter A of the first welding point is about 3.5 times the wire diameter Ф, the sphere becomes uniform and excellent, and the wire and the ball are concentric; the shape of the second welding point is wedge-shaped, and the width D is about 4 times the wire diameter Φ Right and left, the spherical thickness H is 0.6-0.8 times of Ф. The root of the gold ball must not have obvious damage or thinning, and there must be no obvious crack at the wedge of the second solder joint.

Figure 3 First solder joint shape

(4) Other apparent requirements after bonding: no solder wire, no chip, no damaged chip, no pressure electrode. The surface of the chip must not have metal slag, broken wires and other components that cannot be cleaned due to bonding. Pollutants. There is no short circuit, no broken wire, no hook wire.

火狐截图_2017-05-11T03-12-41.240Z.png

Figure 4 Second solder joint shape

2.2 Pull test

Tension test is widely used in thermosonic welding wire. It is a kind of damage test. It can detect the thinnest break point. The characteristics of the test point and the arch wire directly affect the measurement value. The requirements for the pulling force and breakpoint orientation of the LED work key alloy wire are generally: when pulling the wire, the first point of the gold ball cannot be separated from the electrode, and the second point of the wedge cannot be separated from the bracket bonding area, that is, no matter what the pulling force F is Both are judged to be unqualified; if disconnected from other points, a gold wire diameter Ф25um pulling force value F> 5g is a pass, and a gold wire diameter Φ32um pulling force value F> 7g is a pass.

    3. Bonding process conditions

3.1 Bonding temperature

The bonding temperature can help remove surface contaminants, such as moisture, oil, water vapor, etc .; increasing the vividness of the molecules is beneficial to the composition of the alloy. However, too high temperature will not only cause excessive oxides to affect the bonding quality, but also due to the effects of thermal stress and strain, the accuracy of image monitoring and the reliability of the device will also decline. In practice, the temperature control system will increase the preheating zone and cooling zone, and the stability of the forward control. At present, the bonding temperature of LED chip bonding machine (eg Eagle60 type) is generally set at 180-250 ° C.

3.2 Bonding machine pressure / power

Ultrasonic power makes the welding wire and the welding surface soft, heat energy is generated, and the constituent molecules interfit with each other, changing the spherical standard. Ultrasound power has the greatest impact on the quality and appearance of the bond, as it plays a dominant role in the deformation of the bond ball. Too little power can cause too narrow, unshaped bonds or tail wires to rise; too much power can cause root cracks, bond depressions, or pad splits.

Ultrasonic power and bonding pressure are parameters that are related to each other. Increasing the ultrasonic power generally requires increasing the bonding force so that the ultrasonic energy is transmitted to the bonding point through the bonding thing. Therefore, when setting the bonding machine pressure and power parameters in the production process, it is necessary to close the two to a good summary. Actively set according to the type of machine and the practical situation encountered in the production process, and strive to find the best distribution combination .

3.3 Bonding time

Bonding time refers to the time for controlling the effect of ultrasonic energy. Generally, the time for LED chip bonding machine (eg Eagle60 type) is set at 8-20ms. Generally speaking, too short wire bonding time does not constitute an excellent alloy, and too long wire bonding time is the cause of poor tensile force or chip electrode damage. The longer the bonding time, the more energy the lead ball absorbs, the larger the diameter of the bonding point, the stronger the interface and the lower the neck, which will cause the bonding point to exceed the pad distance and increase the probability of void generation. Therefore, it is very important to set a suitable bonding time.

4, bonding things and raw materials

4.1 Cleaver

The choice and application of the bond splitter has an important influence on the quality of the solder joint. The splitter life is generally 2 million points. With the increase of the number of welding points used by the splitter, the wear of the splitter is also getting more severe. Figure 7 is a comparison of the appearance of the new splitter from the beginning to the 3500K solder joint. With the wear of the splitter, the quality of the solder joints gradually deteriorated. Figure 8 is a comparison picture of the appearance of the first and second solder joints as the number of splitter welds increases.

火狐截图_2017-05-11T03-12-51.480Z.png

Figure 6 The number of solder joints and the appearance of the solder joint

4.2 Gold Wire

As an important raw material, gold wire must have several important characteristics: excellent mechanical function and conductive function, suitable breaking force, selection of the correct standard, clean surface without pollution and no harm. At present, most of the gold wire diameter for LED packaging work is 1mil or 1.25mil, the purity is 99.99%, the elongation is generally 2% -8%, and the crack load is generally required: 1mil gold wire is greater than 10g, and 1.25mil gold wire is greater than 16g.

Too soft gold wire can cause the following:

(1) Sagging arch wires;

(2) spherical instability;

(3) The neck of the ball is shortened briefly;

(4) The gold wire is easy to crack.

  Too hard gold wire can cause the following disadvantages:

(1) punch out the chip electrode or epitaxy;

(2) The neck of the golden ball is cracked;

(3) Difficulties in forming alloys;

(4) Arch wire arc control is difficult.

4.3 Influence of lead bracket quality on solder joints

(1) Generally affect the second solder joint;

(2) The unevenness of the surface causes the energy to be lost during the welding process, and the solder joints are asymmetric;

(3) Poor adhesion results in poor plating quality, which is directly reflected in poor tensile strength after welding;

(4) The surface is bad (cleanliness, oxidation). When several parameters of the welding wire cannot damage the surface pollution layer, it will affect the quality of the welding wire.

4.4 Effect of chip electrodes on solder joints

(1) The chip electrode itself is unreliable in vapor deposition, which causes the electrode to fall or be damaged after the bonding wire.

(2) The chip electrode itself has poor solderability, which may cause solder balls to be soldered.

(3) The surface of the chip electrode is dirty, such as the glue on the rack, other objects contact the surface of the chip; improper storage of the chip causes the electrode surface to oxidize, etc. Because the standards of metal melting balls and pads are small, the cleanliness of the bonding surface is very active, and the fine contamination of the bonding surface may cause the metal atoms between the two to fail to conduct, which constitutes failure or virtual soldering.

   5.Conclusion

The bonding process is the most important and crucial process technology in the LED packaging industry, which affects the electrical functions and reliability of the packaged products. This article introduces the quality control standards for bonding wires and balls, introduces parameters such as bonding time, pressure, and power that affect the quality of bonding. Others also talk about things such as cleavers, gold wires, and raw materials for bonding. The impact of quality.

Analysis of the misunderstanding of thickness of LCD splicing screen

Abstract: LCD splicing screens are widely used in various work fields with a series of flashing advantages such as high definition, high brightness, and high contrast that other flashing devices cannot compare; LCD splicing in the large screen market also has an obvious advantage that LCD splicing has super The thin and stylish appearance makes the LCD splicing as much as possible with the space wall planning instead of a large forward protrusion. This aesthetic advantage is also enough to defeat DLP splicing.

LCD splicing screens are widely used in various work fields with a series of flash advantages such as high definition, high brightness, and high contrast that other flash devices cannot compare; LCD splicing in the large screen market also has an obvious advantage: LCD splicing has ultra-thin, The stylish appearance allows the LCD splicing to be as close as possible to the wall plan of the space, rather than a large forward protrusion. This aesthetic advantage is enough to defeat DLP splicing.

With the advent of LCD splicing technology, LCD splicing screen products have become thinner and thinner, the screen body is more beautiful, more convenient for equipment, and can also add snapshot response time; related research indicates that the thickness of the large splicing screen has decreased by 20, and its care speed Will advance on the basis of 35. So, does this mean that the thinner the LCD splicing product is, the better? Of course the answer is no, because thinning the product will also bring certain negative effects, and users must have some understanding before buying.

The thinner the product thickness, the higher the requirements for the production process. Assuming that the production process is not close, not only the color of the screen flashing will become dim, but the viewing angle will also become smaller. At the same time, the probability of the occurrence of bad points on the screen will increase. , And the product yield will decrease. So far, the industry does not have a very complete set of technologies to deal with the above problems. Therefore, to produce light-weight products, manufacturers will have a lot of production costs. Correspondingly, they will be transferred to working users, and the use of costs will also greatly advance. . High cost and multiple risks. This is what users must consider when seeking the ultimate lightweight products. Of course, if the conditions allow, you must choose, it is best to choose a large brand product with guaranteed quality and after-sales service. a good choice.

Looking at the "High Cost-Effectiveness" of Chinese Mainland LED Enterprises from the Frankfurt Exhibition

China's mainland LED companies should be aware of their own advantages, so that talents have a favorable position in the world LED game. Suppose our domestic enterprises fight "high technology" at all costs in the world's LED shopping malls. I am afraid that this is an unrealistic approach at that time or even in two or three years. Perhaps only mid-range and mid-to-high-end products can talents make the most of the "high cost-performance" advantages of our domestic LED companies.

"High cost performance" can also visit Daya Hall

Don't think that "high cost performance" means that there is no technical gold content, and you can only drill and speculate on capital. With the same quality and the same function, LED companies in China can always minimize the cost, which is technical work in itself. However, after all, seeking "high cost performance" is not the same as bottomless, unprincipled, and endless "price war."

The LED companies on the land of Divine Land, whether it is the "double price" Mu Linsen and Foshan Lighting, are still other companies, which company is not a "high cost-effective" master. More than 30 LED companies from the Chinese mainland came to this Frankfurt exhibition with talented products. "High cost performance" is not without technology or low technology.

Consistently committed to brand production, the flag is hostile to the "price war", and the high-quality products are widely welcomed by the market's favorite Mingzhou Technology. This Frankfurt exhibition brought a unique planned outdoor lighting product to European and American shopping malls. This product, called the SHARK series, includes street lamps and new garden lights, patented ceiling lamps and downlights for indoor lighting. The special street light distribution system can maximize the utilization of light energy.

Recently, the cost action has been repeated. Wanrun Technology, which integrates the industrial chain and cross-border Internet advertising media, exhibited flagship products: ORO series LED energy-saving street lights based on European and American high-end shopping malls, PLC intelligent dimming street lights, and MASTER series full-angle cover. High-power module floodlights for outdoor utility lighting, as well as DOB high-voltage downlights, new rugged lamps suitable for DALL dimming, 170LM / W LED tubes, etc.

Relying on the 2008 Beijing Olympic Games, the 2010 Shanghai World Expo, the 2010 Guangzhou Asian Games and many other large events and exhibition lighting projects, the Sanxiong Aurora, which has enjoyed a lot of popularity, has a long-standing brand affinity in dealers and customers. As one of the old exhibitors at the Frankfurt exhibition, Sanxiong Aurora continued to participate in this exhibition from beginning to end, but not to become famous, but to hope for knowledge and experience, hoping to use this exhibition to understand the latest lighting work to expand the intention and deepen with the industry Exchange various energy-efficient lighting solutions.

Hongyan Electric successively won honors such as the New Living Style Award of China's home industry and the most influential smart lighting brand in 2015. It also collaborated with Huawei, JD.com and other famous enterprises to promote smart lighting. At this year's Frankfurt exhibition, Hongyan Electrical Appliances has lost no time in promoting its concept and products of intelligent lighting. In addition, a variety of products such as LED street lights, fire emergency sign lights, LED tri-proof lights, etc. were also exhibited together, very busy.

Sidon Lighting, jokingly said that even if he was crying and starving, he would go to Frankfurt. Its booth planning is very delicate. The new products on display include: Bach III hotel downlights, MINI series track spotlights, ultra-white series CEL6288C and so on.

Overclocking three technologies, a leader in the field of radiator innovation, naturally will not miss the top event in Frankfurt. Overclocking Three Technologies has demonstrated its series of high-quality products to the world, including TGC series stadium light kit, TS series projection light kit, GKH industrial and mining lamp series kit, TG3A series flood light kit, TD ~ MZ surface mounted downlight kit And high-efficiency finned radiators and cold forging radiators.

In the field of Yuanfang Optoelectronics, LED and lighting detection equipment, there are only listed companies in the world, and they have long been well-known in the industry. Regarding such a super-heavy global event in Frankfurt, Yuanfang Optoelectronics has moved out of its housekeeping skills. Its products are sufficient to lead the global LED and lighting detection technology, and have completely independent intellectual property rights, including GO-R5000 full-space fast-distribution photometer, SPIC -200 spectrum colorful illuminance meter and HAAS-3000 high-precision fast spectrum radiometer, etc.

Shanghai Guangmaoda believes that "Technology + Art" is the talent and beauty of China. Therefore, it uses "Keyihua" as its brand name and proclaims "the global pioneer and leader of light art works". Its booth is based on the theme of Water Cube, full of artistic sense.

All these functions are supported by a high-bandwidth wireless network, which supports both point-to-point and mesh networks. Sensity says the technology is now used in 42 smart cities around the world.

Sensity Chairman and CEO Hugh Martin mentioned in a press release: "Looking at the world, rapid urbanization has brought a heavy burden on urban services. The infrastructure that supplies critical social services is aging and power is low, such as fire protection, First aid, public transportation, lighting, sewer systems, sanitation systems, etc. Sensity has long realized that the Internet of Things will be the key to breaking this deadlock. "

Verizon's actions in the field of Internet of Things have been repeated. In addition to this acquisition of Sensity, Verizon launched a network-based Internet of Things approach to developers and ThingSpace last year. Last month, it spent $ 2 billion to acquire a company Network GPS positioning system company Fleetmatics, whose products enable fleet operators to look for a car's fuel consumption, bearing, speed, miles, and more.

In the field of technology, some wonderfully innovative IoT products have also significantly increased, including refrigerators, doorbells, beds and ovens. The Internet of Things is about to usher in an era of prosperity. As the largest wireless network supplier in the United States, Verizon has invested huge amounts of money to produce infrastructure that can connect all aspects of the city. This can clearly show that the logistics network is not a fleeting gimmick.

"Sensity, as an enterprise of IoT solutions, serves a robust smart community of collaborative ecosystems composed of peers. This collaboration will accelerate the implementation of large-scale projects and drive the digital transformation of cities, universities and venues," said Verizon as enterprise Compensates Mike Lanman, senior vice president of products and the Internet of Things.

Prior to that, Sensity had received over $ 70 million in capital injections.
