MEMS sensor technology turned into a racing track safety assistant

Throughout the world today, many technologies that are important to safety and economic prosperity have occupied an important position in sensor information technology. Sensors can be more miniaturized by means of micro-nano processing methods, and MEMS micro-sensor technology is compared to traditional sensors. It not only reduces the size of the sensor, but also improves its performance. It has advantages in terms of sensitivity, dynamic characteristics, and signal-to-noise ratio.

A few days ago, on the race track of the Indianapolis Motor Speedway in the United States, MEMS sensor technology took the lead on the race track to help ensure the safety of the Indianapolis 500-mile race drivers. By combining this emerging MEMS acceleration sensor technology in a 200mph race car, Indy500 became one of the safest races in the history of U.S. racing.

Combined with the new security features developed by the IndyCar engineering team, each racer's headset also includes three high-g acceleration sensors developed by ADI to detect the impact of the collision on the rider. NASA is exploring the possibility of this high-G sensor technology being used to protect astronauts from harm when landing.

"We redesigned the driver's earphone plugged into the ear canal," said Jeff Horton, director of engineering at IndyCar. "In the event of an impact, ADI's MEMS sensors were able to measure all the impact that the rider's head may experience during an accident."

IndyCar is now equipped with these high-g acceleration sensors and writes data from these acceleration sensors into a black box that can record accident records for 90 seconds of data capacity. In the event of an accident, the system will be shut down when it is affected by an impact. Acceleration sensor data 30 seconds before and 60 seconds after the impact was related to head injury data. The purpose is to extract valuable information from these sources to improve the safety of the IndyCar cockpit.

With the help of the Center for Biomechanics Research of the National Highway Traffic Safety Production Supervision Authority, accidents that can lead to injuries will be reproduced. Using the collision dummy “Thor” equipped with 15 high-g acceleration sensors in the center, IndyCar engineers can simulate crash damage.

With the development of technology, sensors will also play a more important role, and bionic smart sensors will also develop with the progress of bioengineering technology. The future development of sensor technology will realize more possibilities.

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 Printed Circuit Board
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.

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.

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. 

Kinds of LED PCB Circuit Board

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.

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.
