Failure mode and effect analysis is "potential failure mode and consequence analysis", or FMEA for short. FMEA is a systematic activity in the product design stage and process design stage to analyze the subsystems and parts constituting the product and each process constituting the process one by one, find out all potential failure modes and analyze their possible consequences, so as to take necessary measures in advance to improve the quality and reliability of products.

What is FMEA? The official definition is: FMEA, namely failure mode and effects analysis, is to analyze the subsystems, parts and processes of products and equipment one by one in the product design stage and process design stage, find out all potential failure modes and analyze their possible consequences, so as to take necessary measures in advance, A systematic activity to improve the quality and reliability of products or equipment.

Failure analysis is a new developing subject, which has been popularized from military industry to ordinary enterprises in recent years. It is generally based on the failure mode and phenomenon, through analysis and verification, simulate and reproduce the failure phenomenon, find out the cause of failure, and dig out the failure mechanism. It has strong practical significance in improving product quality, technology development and improvement, product repair and arbitration of failure accidents. View >>

FMEA is failure mode and effect analysis, which means failure mode and effect analysis. It is an analysis method used to determine potential failure modes and their causes. FMEA is a quantitative qualitative analysis and calculation method to analyze the possible (and / or occurred) failure modes and judge the risk degree caused by the possible (and / or generated) consequences, and take targeted improvements according to the risk, so as to understand the product (and / or manufacturing process) design capability, Reach a pre prevention and implement improvement measures.

When mechanical parts lose their working capacity or fail to meet the design requirements for some reasons, it is called failure. The failure of mechanical parts does not simply mean damage, which can be summarized into three situations: completely unable to work; Although it can work, its performance is poor and exceeds the specified index; Serious injury and loss of ability to work safely.

The failure of mechanical parts refers to the partial or complete loss of design function during the use of parts. The parts are completely damaged and cannot continue to work; Or the parts have been seriously damaged. If you continue to work, you will lose safety; Or although it can work safely, it has lost the design accuracy and other phenomena belong to failure. View >>

The significance of part failure analysis is to reduce and prevent the recurrence of failure of similar mechanical parts, ensure product quality and improve product competitiveness. In order to prevent the failure of parts, it is necessary to analyze the failure of parts, that is, by judging the failure form of parts, determining the failure mechanism and causes of parts, selecting materials pertinently, determining reasonable processing routes, and putting forward failure prevention measures.

The failure forms and causes of metal materials are closely related. The failure forms are the apparent characteristics of the material failure process, which can be observed in an appropriate way. The failure reason is the physical and chemical mechanism leading to component failure, which needs to be diagnosed and demonstrated through the investigation and research of failure process and the macro and micro analysis of failed parts. With the progress of society and the development of science and technology, metal products are more and more widely used in industry, agriculture, science and technology and people's life. Therefore, the quality of metal materials should be paid more attention. View >>

Most of the faults in electronic equipment are ultimately caused by the failure of electronic components. If you are familiar with the failure causes of components and locate the failure causes of components in time, you can eliminate the faults in time and make the equipment operate normally. The rapid development of electronic component technology and the improvement of reliability have laid the foundation of modern electronic equipment. The fundamental task of component reliability is to improve the reliability of components. View >>

PCBA is a system composed of PCB and various electronic components. The main material of PCB is the composite of glass fiber and epoxy resin, which is divided into single panel, double-sided board and multilayer board. As the carrier of various components and the hub of circuit signal transmission, it has become the most important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment. Due to the development trend of PCB high density and the environmental requirements of lead-free and halogen-free, more and more PCBs have various failure problems, such as poor wetting, plate explosion, delamination, CAF and so on. The acquisition of PCB failure mechanism and causes will be conducive to the quality control of PCB in the future, so as to avoid the recurrence of similar problems. View >>
