What companies can do failure analysis? Chuangxin testing team is composed of dozens of professional engineers and industry elites. It has built three standardized laboratories with an area of more than 1000 square meters. It has invested heavily in international advanced testing equipment and strictly followed international testing standards and methods. It has obtained CNAs certification and international mutual recognition qualification. Failure analysis is an activity to simulate and reproduce the failure phenomenon, find out the cause of failure and dig out the failure mechanism through analysis and verification according to the failure mode and phenomenon. It has strong practical significance in improving product quality, technology development and improvement, product repair and arbitration of failure accidents. The methods are divided into destructive analysis, nondestructive analysis, physical analysis, chemical analysis and so on. View >>

Most of the weldments are welded by steel plate or section steel. Aluminum and aluminum alloy, copper and copper alloy, titanium and titanium alloy, cast iron, plastic and other materials can also be welded. The weldability of materials is a prerequisite to determine whether the structure can be welded. Designers must consider the weldability of materials. Attention shall be paid to the design of welded joints and welds in the design. Try to make the street form simple and the structure continuous, reduce the turning of the force flow line, do not choose too large weld leg size, reduce the weld section size, and consider the feasibility and convenience of structural manufacturing.

In order to obtain high-quality welded joints, it is necessary to reasonably select welding materials. Because the working conditions of welded parts are very different in operation, the material properties and components of base metal are very different, and the manufacturing process of parts is complex, it is necessary to comprehensively consider all aspects to determine the corresponding welding materials. What are the welding materials? Next, let's take a look at the principles that should be followed in selecting welding materials. View >>

For the incoming components, first check them according to relevant standards and specifications, and pay special attention to whether the performance, specification and packaging of components meet the ordering requirements, whether they meet the requirements of product performance indicators, whether they meet the production requirements of assembly process and assembly equipment, and whether they meet the storage requirements. The incoming inspection of components is a very important link. By strictly controlling the incoming link, it has an important impact on the final product quality. In order to ensure the quality of PCBA processing and the smoothness of the processing process, it is necessary to conduct incoming inspection on the customer supplied materials. Next, I will introduce the content of incoming inspection of components. View >>
