In recent years, the development of electronic component inspection mainly focuses on automation and intelligence. On the one hand, with the continuous improvement of hardware processing capacity, engineers can use more advanced image analysis to solve complex inspection problems. On the other hand, the demand for automated applications has gradually brought the development of detection technology to the integration of collection, analysis and judgment. The importance of electronic product detection is reflected in that, with the continuous development of science and technology, electronic products begin to enter every corner of human production and life, and electronic components play a decisive role in chips.

Safety regulation certification is actually a technical barrier. In order to restrict the products of other countries from entering their own countries, all countries in the world have different requirements for safety regulations, and they are still mandatory. In order to protect the rights and interests of users, the safety inspection of products will be more and more extensive, and more attention will be paid to it. Therefore, before the formal sale of electronic products, safety inspection is an important link. What are the common safety inspection items of electronic products? Let's have a look. View >>

Lead free solder is mainly used in electronic packaging, temperature fuse and other fields to realize the connection function between the connected materials. For example, the connection between electronic components and circuit boards can be realized by reflow soldering or wave soldering. So what is the definition of lead-free solder? What are the characteristics and technical difficulties of lead-free welding? In the whole process of SMT placement, an excellent lead-free solder joint plays a vital role in the quality of the whole PCBA finished product. Let's discuss the characteristics of lead-free welding process and the technical problems. View >>

What is salt spray test? Salt spray test is an accelerated corrosion resistance evaluation method of artificial atmosphere. It atomizes a certain concentration of salt water; Then spray it into a closed constant temperature box to reflect the corrosion resistance of the tested sample by observing the change of the tested sample after being placed in the box for a period of time. It is an accelerated test method. The salt concentration of chloride in the salt fog environment is several times or dozens of times that of the salt fog content in the general natural environment, which greatly improves the corrosion rate. The time to obtain the results of salt fog test on products is also greatly shortened. What materials should be prepared for salt spray test? In order to help you understand in depth, the following contents are sorted out by Chuangxin testing network for your reference. View >>

RoHS directive 2011/65/eu (also known as RoHS 2.0 directive) is a re update of the previous EU ROHS directive 2002/95/ EC. The new directive came into force on 21 July 2011 and is consistent with the new legislative framework. It stipulates restrictions on the use of hazardous substances in electrical and electronic equipment (EEE). Such harmful substances are Mercury, lead, cadmium, polybrominated biphenyls, dibutyl phthalate, diisobutyl phthalate, hexavalent chromium, polybrominated diphenyl ethers, etc. View >>

The failure forms of metals are closely related to the failure causes. The failure forms are the apparent characteristics of the metal failure process, which can be observed in an appropriate way. Through metal failure analysis, we can know whether there are problems in the performance of metal materials or metal equipment in advance, so as to avoid possible accident hazards in engineering application.

In the narrow sense, failure refers to the phenomenon that mechanical and electrical products lose their functions, while failure analysis is to analyze and diagnose the failure mode, cause and mechanism, and study the technical activities and management activities that take remedial prediction and preventive measures. At the same time, the comprehensive discipline that intersects with related theories, technologies and methods is called failure science. In fact, the so-called failure analysis also includes many aspects. What are the aspects of the analysis here? View >>
