After nearly 100 years of development of original film X-ray photography technology, X-ray inspection technology has formed a relatively complete X-ray inspection technology system. In order to meet the requirements, new detection technologies are constantly innovated, and the application of Xray online detection technology is one of the best. It can not only detect invisible solder joints, such as BGA, but also qualitatively and quantitatively analyze the detection results, so as to find faults as soon as possible. View >>

As a model of small devices, BGA devices are widely used in electronic products in recent years. Compared with QFP package device or PLCC package device, BGA device has many advantages, such as more pins, smaller inductance and capacitance between pins, good pin coplanarity, good electrical performance and heat dissipation performance.

In the production of electronic enterprises, welding is one of the important links in the manufacture of electronic products. If there is no corresponding process quality assurance, there will be some circuit board problems, and some defects can not be judged by the naked eye. The common defects of PCB board are false soldering, bonding and copper foil falling off. In mass production, from screening and testing of components to assembly and welding of circuit boards are completed by automatic machinery, which is conducive to ensuring the consistency of process conditions and assembly and welding operations and improving product quality.

NDT is the abbreviation of non-destructive testing. It refers to a testing method for materials or workpieces that does not damage or affect their future performance or use. Through the use of NDT, the defects existing in the interior and surface of materials or workpieces can be found, the geometric characteristics and dimensions of workpieces can be measured, and the internal composition, structure, physical properties and state of materials or workpieces can be measured. It is widely used in the detection of metal materials, non-metallic materials, composite materials and their products, as well as some electronic components. View >>

In the field of nondestructive testing, industrial CT testing and X-ray testing both use X-rays to detect the interior of objects. Industrial CT is industrial computed tomography imaging. It can clearly, accurately and intuitively display the internal structure, composition, material and defect of the detected object in the form of two-dimensional sectional image or three-dimensional image without damage to the detected object. The working principle of X-ray imaging detector mainly uses the penetration of X-ray. The wavelength of X-ray is very short and the energy is very large. When it shines on the material, the material can only absorb a small part, and most of the energy of X-ray will pass through the gap of material atoms, showing a very strong penetration ability. On the difference of X-ray absorption View >>

Nondestructive testing is defined as the method of inspecting and testing the structure, properties and state of the internal and surface of the test piece by means of physical or chemical methods and with the help of advanced technology, equipment and equipment without damaging the test piece. Nondestructive testing technology is widely used in industry, such as aerospace, nuclear industry, weapon manufacturing, machinery industry, shipbuilding, petrochemical industry, railway and high-speed train, automobile, boiler and pressure vessel, special equipment, customs inspection and so on. So, what are the application characteristics of nondestructive testing technology? View >>

In the semiconductor shortage market, more and more counterfeit chips began to circulate in the electronic field. This will bring quality risks to more electronic products and seriously damage the interests of manufacturers and users. San Xin is an industry slang. It usually refers to chips without original packaging. It will also be used to refer to chips eliminated due to quality problems in the assembly line and refurbished chips. Some second-hand refurbished chips can be used for new equipment, but the service life of consumer grade chips is about 5 years. If they are used after refurbishment, their service life and performance parameters will be greatly reduced. What is the quality of the "refurbished goods" in the chip? What are the common means of refurbishment? If you are interested in what this article will cover, read on. View >>
