In the stage of workpiece design and R & D, the internal defects of the workpiece are detected through industrial CT, and the size of the measured structure is compared with the design value to find the position and size of the deviation and assist in the improvement of the manufacturing process. After the workpiece is manufactured, its defects or dimensions need to be measured to check whether it meets the standard. Industrial CT measurement also plays an important role in the assembly parts. After the parts are assembled, the internal structure can not be seen. For the parts with strict requirements for the assembly structure, measure the size of the assembly structure through industrial CT, whether the channel is blocked, whether the channel is too narrow, whether the docking is close, etc. The following is a brief analysis of industrial CT test for your reference.

At present, most of the electronic components commonly used in integrated circuits are sealed with epoxy resin or other glue and alloy, and there is often the phenomenon of circuit board soldering. Therefore, detecting circuit board soldering is a very important link. False soldering of circuit board has always been a common problem in the electronic industry. Due to the compact and complex internal structure and miniaturized shape of electronic products, ordinary testing instruments can not detect their internal defects. Therefore, it is difficult to solve the problem of how to effectively detect false soldering of circuit board. To solve this problem, the skilled workers in the factory came up with various methods: View >>

Chip is the carrier of integrated circuit, which is divided by wafer. There are traces of chip in our smart phones, computers, televisions, automobiles and air conditioners. As an electronic component with high integration and precise structure, and the continuous emergence of various new packaging technologies, the requirements for circuit assembly quality are higher and higher. The chip X-ray detection equipment mainly uses the X-ray generated in the X-ray inspection machine to irradiate the inside of the chip. The X-ray has strong penetration and can image after penetrating the chip. The internal structure fracture of the chip can be seen at a glance. The main feature of using X-ray to detect the chip is that there is no damage to the chip itself. Therefore, this detection method is also called nondestructive testing. View >>

Fuse is a common electronic component. Fuse is also called current fuse. Iec127 standard defines it as "fuse link". It mainly plays the role of overload protection. It is a very key component in electronic products, which plays a protective role in circuit safety, so as to effectively ensure that when the product is powered on, it will not be broken down by excessive current and damage the electronic products.

The reliability of the power module itself is very important and can be used for power applications of digital or analog loads. But in fact, due to the complexity of the working environment of the power supply system, if there is no reliable system application design, the power supply will eventually fail. Because of its high reliability, small size, high power density and high conversion efficiency, the design of power supply system becomes simpler and simpler, so it is widely used. The following introduces the main design measures and methods of power module reliability. Let's have a look. View >>

When it comes to electronic components, everyone should be familiar with them. What about the reliability of electronic components? The reliability of electronic components is an important factor affecting the reliability of products. Engineers need to select electronic components in circuit design, an essential part of which is the reliability of electronic components, and the inherent reliability of electronic components is the most easily ignored. Therefore, in order to ensure the reliability of products, we must ensure the reliability of electronic components. View >>

Nondestructive testing is a testing technology to check the internal or surface defects of materials without damaging the tested materials, or to determine some physical quantities, properties and organizational states of materials. Nondestructive testing technology is needed in almost all areas of manufacturing, service, maintenance or overhaul inspection. At present, there are many kinds of nondestructive testing technologies in practical application. In addition to the five conventional nondestructive testing methods of ray, ultrasonic, magnetic particle, penetration and eddy current, there are also microwave, acoustic emission, laser, infrared and so on. The following introduces the classification and differences of several commonly used nondestructive testing applications. View >>
