According to Seshu Madhavapingdy, vice president of product management at Qualcomm, "We are pleased to introduce the Qualcomm fingerprint sensor as it supports a slimmer and avant-garde form factor, a unique mobile authentication experience and enhanced security certification. This will help OEMs and Operators add value to new breakthrough terminals, offering truly differentiated terminals that will make a signature change to smartphones."
It is understood that Qualcomm has just released a fingerprint recognition sensor with good penetrating power. The Under Display created for advanced mobile phones can be placed under the 1200μm (1.2 mm) OLED screen, even if it can successfully identify the fingerprint. Among other materials, this finger sensor has a higher level of fingerprint recognition. Among them, the glass display designed for medium and low-end mobile phones effectively recognizes the thickness of 800μm (0.8 mm) in aluminum materials. The effective thickness is 525 μm (0.525 mm).
This fingerprint recognition sensor is extremely penetrating, which means that whether the future smart phone uses front fingerprint recognition or rear fingerprint recognition, the high-end display does not need to be on the outer casing of the mobile device. Drilling, which can greatly improve the aesthetics of the smartphone. In addition to its penetrating power, this fingerprint sensor has excellent water resistance and is very resistant to oil and other liquids.
To solve these problems, Qualcomm's three new sensors are based on ultrasonic technology. It is reported that the fingerprint recognition sensor uses technology that focuses on sound waves rather than light, and therefore does not affect the accuracy of the sensor or display.
Industry sources told Lei Feng that Qualcomm's second-generation fingerprint sensor is called "black technology" called "current design" using ultrasonic technology. Madhavapeddy also said that fingerprint sensors are "very powerful" and that common problems with broken or damaged screens do not compromise the ability to unlock devices. According to Lei Feng.com, the sensor is compatible with the Google Android operating system and is supported by Snapdragon 660 and 630 and some non-Snapdragon platforms.
It is worth expecting that the prototype of the fingerprint sensor installed in the new mobile phone will be exhibited at MWC Shanghai, which was designed in cooperation with Vivo. Commercial availability is expected to be in the summer of 2018.

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.
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.
In China, there are many PCB manufacturers and suppliers. Jinghongyi PCB is one of the LED PCB board manufacturers. We only provide LED PCB fabrication services. LED PCB design is not our specialty and business scope.
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.
