Should copper be applied to the PCB design surface? Should copper be applied to the PCB design surface? Cheersonic In pcb design, we often wonder whether the surface of pcb should be coated with copper? This actually depends on the situation. First of all, we need to understand the advantages and disadvantages of surface copper coating. First of all, let's look at the benefits of copper coating on [...]

LCD vs OLED LCD vs OLED - Spray Protective Film - Ultrasonic Atomizer - Cheersonic The following article comes from the hardware notebook, the author snail To understand how the screen works, you must first understand what a pixel is. The whole picture you see is actually made up of countless small dots, and these small dots are what we call pixels. Each pixel is composed of three [...]

Why is the battery life of the mobile phone always insufficient? Why is the battery life of the mobile phone always insufficient? How much do you know about those strategies for power optimization? In the design of mobile consumer products, power consumption and battery life are always a big challenge. Taking mobile phones as an example, the larger the battery capacity is, the lower the chip power consumption [...]

Polyimide Film Technology Polyimide has been widely used in electrical appliances, electronic devices, aerospace, new energy and other fields due to its excellent comprehensive properties such as high temperature resistance, high strength, high modulus, electrical insulation, radiation resistance, corrosion resistance, and humidity resistance. Applications. With the development of modern technology and industry, the application field of polyimide film is expanding, and the global demand for polyimide film is [...]

Principle of Electromagnetic Shielding Electromagnetic shielding can generally be divided into three types: electrostatic shielding, magnetostatic shielding and high-frequency electromagnetic field shielding. The purpose of the three types of shielding is to prevent the external electromagnetic field from entering a certain area that needs to be protected. However, due to the different characteristics of the field to be shielded, the requirements for the material of the shielding shell [...]

How much do you know about electromagnetic shielding? Original: Engineers look at marine engineering No matter what electronic product is, EMC is always a problem that it needs to face. EMC is Electromagnetic Compatibility, or electromagnetic compatibility. EMC is divided into EMS (electromagnetic susceptibility) electromagnetic immunity and EMI (Electromagnetic interference) electromagnetic interference. It is to evaluate the stability of the product itself, and the other is to evaluate [...]

Electromagnetic Shielding With the rapid development of electronic technology, there are more and more electronic products and devices. Computers and other radio transmitting devices will generate electromagnetic waves of different wavelengths and frequencies, and electromagnetic pollution will follow. So how to solve the problem of electromagnetic pollution, the main method is to use electromagnetic shielding materials. Electromagnetic shielding is to use electromagnetic shielding materials such as metal to [...]

Semiconductor Equipment Is Hard To Find Semiconductor Equipment Is Hard To Find - Sensor Spray - Cheersonic Delays in the delivery of semiconductor manufacturing equipment are no longer "news", but in 2022, the global shortage of chips and manufacturing equipment is still spreading, and it seems that it cannot be solved in the short term. Longer equipment delivery time also means production capacity The improvement is slower, and [...]

Innovative approach reveals surprising semiconductor properties Innovative approach reveals surprising semiconductor properties - Cheersonic In combination with a new type of thin oxide film, a research team studying the properties of semiconductors has observed a surprising new source of electrical conductivity from oxygen atoms trapped inside. Scott Chambers, a materials scientist at the Department of Energy's Pacific Northwest National Laboratory, reported the team's findings at the 2022 Spring [...]
