What is the thermal hardness of cemented carbide?
The reason why cemented carbide (cemented carbide) can be widely used in aerospace, aviation, navigation, consumer electronics, national defense, military industry, medical treatment, automobile and other fields is that it has excellent physical and chemical properties, namely, high specific gravity, high hardness, high strength, good thermal hardness, wear resistance, heat resistance, acid and alkali resistance. What is the thermal hardness of cemented carbide?
There are two types of fixture, namely, fixture and inspection fixture
The fixture is divided into two types, namely, fixture and inspection fixture. The former is used for machining, welding, processing and assembly and other processes to facilitate processing and meet the needs of accuracy. The latter is used for inspection. Because some mechanical dimensions are not easy to measure and their shapes are complex, it is necessary to design special inspection blocks or inspection tools designed for a certain product for inspection, such as plug gauges and ring gauges, But some of them are irregular, so we must design a special inspection tool to measure its size
FPC is what we often call flexible board, which is also called flexible circuit board. It is made of polyimide or polyester film and other circular substrates. It is light and thin, has high density, high flexibility, and can be bent and folded. It has advantages that other types of circuit boards do not have. Compared with traditional interconnection technology, FPC flexible circuit board can withstand millions of times of bending, easy installation, good heat dissipation, and is favored by the market.
Metallographic preparation of FPC flexible circuit board
Electronic products play an important role in our life. Flexible circuit boards exist in mobile phones, digital cameras, cars and computers we use every day.
Application of laser processing in FPC industry
FPC board, also known as flexible circuit board, flexible circuit board, flexible circuit board, flexible circuit board, and flexible board, is a special type of PCB board. FPC board has the characteristics of light weight, thin thickness, soft and flexible. Compared with hard circuit board, flexible circuit board soft board has many advantages that hard printed circuit board does not have. For example, free bending, winding and folding can be arranged arbitrarily according to the requirements of spatial layout, and can be moved and expanded freely in three-dimensional space, so as to achieve the integration of element, component assembly and wire connection. The use of flexible circuit boards can greatly reduce the volume of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPCB has been widely used in aerospace, military, mobile communications, portable computers, computer peripherals, PDAs, digital cameras and other fields or products.
What can we do through the opening test of the chip?
According to the chip opening detection, we can observe the internal structure more intuitively, and analyze the sample condition and the important causes after opening.
How does COMS detect hard disks?
There will be various English short sentences after problems occur during POST. The short sentences contain very important information.
CMOS Image Sensor Industry Research Report: The Core of Future Camera Technology
CMOS image sensor (CIS) is a chip that converts photons into electrons for digital processing and image signals into digital signals. It is mainly used to create images in digital cameras, digital closed-circuit television cameras and digital video cameras. It is a key component of digital cameras. As the functions of the camera include photographing, video recording, image recognition,
