2012 Smartphone Market Development Inventory

The smart phone market in China is developing well, but the growth rate is slow. Competition between the major operating systems will be more prominent, and gradually promote the popularity of smart phones in the way of the alliance camp. Recently, foreign media have conducted an inventory of the development of the global smart phone market this year. The following is an excerpt of the article:

Smartphone mobile payment development bottlenecks

Mobile payment has undoubtedly become a major mainstream feature of smartphones in 2012. In 2012, electronic purses, Square readers and near-field communication technologies became the highlights of smartphones in mobile payments.

In 2012, mobile payments have grown to the level of installation and use of mobile payment devices in physical stores. As a result, a large number of mobile payment companies have emerged as the main business and have thus become famous. However, because consumers nowadays are accustomed to using bank cards for consumer transactions, mobile payments cannot be accepted by consumers in a short time.

Mobile security is worrying

According to statistics, as of October 2012, the global mobile malware infection rate was about 1%. According to the current year, global smartphones (including Android smart phones) accounted for 1 billion users, which means that 10 million mobile phones were Malware attack. According to data released by Kaspersky Lab, only in the third quarter of 2012, there were 9000 new Android mobile phone malware worldwide. Another industry insider expects that by the end of 2013, there will be 18 million Android mobile phones infected with malware worldwide.

The patent dispute is in full swing

Nothing about the inventory of smart phones in 2012 will save the patent dispute. In the past year, there have been numerous lawsuits involving claims made by smart phone manufacturers, applications for bans, and so forth. Apple Inc. is undoubtedly the protagonist of almost all the patent disputes this year. Its dispute with South Korea's Samsung ignited the fuse of the global patent war. Eventually Apple won victory and reaped one billion US dollars in compensation. In addition, HTC, Motorola Mobile, RIM, Nokia and other mobile phone giants have also fallen into the "scissors" of the patent dispute. Looking ahead to the outlook for the global mobile phone market in 2013, it has become inevitable that the dispute over patent rights in the industry will continue to exist.

The most comprehensive introduction of LED PCB

The relationship between LED and PCB

The Printed Circuit Board is a genius innovation of circuit technology, laying less space and materials for more complex and large-scale circuits. The printed circuit board is such an important invention in circuit technology because it makes electrical and electronic components smaller, more flexible and more precise. For example, FPC( Flexible PCB ), Multilayer PCB , BGA PCB , rigid- Flex PCB and so on.

LED is an abbreviation for light-emitting diode. An LED is essentially a two-lead semiconductor device that emits light when current passes in a certain direction. Although LEDs start with devices that only emit low-intensity infrared light, this technology has been widely used in lighting for many years. Modern LEDs not only provide high intensity, very bright light but also different uses and use in different scenes, such as plant growth lights, car lights, street lights, traffic lights, shadowless lights in hospital operating rooms.

Soldering the LED chip to the PCB Board , as long as the PCB circuit is connected in some way, it will illuminate, which forms the LED PCB. LED PCBs typically also have a heat sink and ceramic pedestal to hold the circuit in place and allow the smooth operation of the circuit. A heat sink is required because LEDs tend to generate a lot of heat, which can damage the PCB and the equipment that connects the circuits.

Because LED will produce a lot of heat, led PCB generally uses metal substrate as its production material. Metals with the ability to dissipate heat quickly have proved to be a better choice. Generally, whenever led PCB is designed, Aluminum PCB is preferred. Aluminum PCB usually also contains a thin layer of dielectric, which can dissipate heat faster.

In addition to general lighting, led PCB can also provide visible light, infrared and ultraviolet light. Compared with other light sources, LED PCB can provide higher energy.

We are a professional LED PCB manufacturer and assembler in China, In this article, we would like to introduce in detail what is LED PCB, the materials used in manufacturing and LED circuit boards manufacturing, the application of LED Printed Circuit Boards and so on.

LED PCB board Introduction

LED PCB has many other names, such as LED PCB board, LED circuit, LED Circuit Board, led printed circuit boards, PCB board for LED.

In a sense, LED PCB and aluminum PCB belong to the same kind of PCB products, because their uses and materials are mostly the same.

With the popularization and widespread use of industrial lighting and civil lighting, whether outdoor or indoor, family or commercial buildings and factories, lighting provides the guarantee of its normal operation.

Of course, nowadays, with the development of human society, environmental pollution has become a difficult problem in the world. In order to reduce the consumption of coal, such as coal used for power generation in thermal power plants, coal combustion pollutes the atmosphere very seriously. In order to save energy and protect the environment, LED lights and previous lighting methods have great advantages, except for energy. Besides providing brighter lights, it also contributes to environmental protection.

LED PCB Meaning

LED circuit board is a kind of printed circuit board.

LED PCB Board manufactureing

Both LED aluminium PCB and FR-4 fiberglass circuit board belong to PCB. To say differently, only compare LED aluminium substrate with FR-4 fiberglass circuit board.

LED aluminium substrate is printed on the surface of aluminium material with better thermal conductivity, and then weld electronic components on it.

In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. 

The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current. 

Very simple circuits are used for low-power indicator LEDs. More complex, current source circuits are required when driving high-power LEDs for illumination to achieve correct current regulation.

An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.

LED PCB Board Material - LED PCB raw material, LED bulb PCB raw material, LED strip PCB material

Metal core PCBs are often chosen for LED applications because they have enhanced heat dissipation capabilities. In particular, aluminium is usually used to make circuit boards for LED lamps. Aluminum substrates usually consist of thin layers of thermal conductive dielectrics that can be transported and have much more efficient heat dissipation than conventional rigid PCBs.

Compared with other electronic components, LED generates more heat, which requires PCB to heat very well. For this special feature, Metal Core PCB is often used in LED circuit boards, especially Aluminum Core PCB .

The following is the heat dissipation capacity of PCB plates of different materials, from weak to strong

1. FR4, common PCB board material;

2. Alumina substrate;

3. There is no doubt that the thermal conductivity of ceramic PCB is the best among many materials;

4. The thermal conductivity of alumina ceramic circuit board can be about ten times that of the aluminum substrate;

5. The thermal conductivity of Slyton aluminum nitride ceramic circuit board is ten times higher than that of alumina;

In this kind of ultra-high thermal conductivity, LED light attenuation will be greatly weakened, and its service life will be greatly increased.
