For ordinary people, failure analysis is a strange concept, but for enterprises to improve product quality and competitiveness, failure analysis can help reduce and prevent the recurrence of similar failure phenomena; ordinary people encounter product quality disputes, can also use failure analysis to determine right and wrong. Moreover, failure analysis test is indispensable to the identification of accident liability, the detection of criminal cases, the determination of liability for compensation, the upgrading of product quality & hellip; & hellip.

Liu Xuesen, head of Shanghai Huabi Judicial Appraisal Institute, is such a truth-locked & ldquo; troubleshooter & rdquo;.

After graduating from Shanghai Jiaotong University, Liu Xuesen studied failure analysis and reliability test technology, participated in the preparation of the first AMD device analysis laboratory in China, and then worked in Intel's reliability and failure analysis department. In 2004, Liu Xuesen went to Fudan to study MBA. With professional background and abundant work experience, coupled with the accumulation of management knowledge, Liu Xuesen started his business. In 2006, Liu Xuesen and two friends established Huabi Testing Technology Co., Ltd. to engage in reliability and failure analysis of electronic products, material and physical and chemical components testing, research and development and trial production of related professional technical uniforms. Business. In 2008, & ldquo; Huabi & rdquo; involved in the field of forensic expertise, and obtained the forensic expertise license in 2011 and Jiangsu Province in 2012, respectively.

In a brand of automobile, the window switch fails less than a week after the new car is sold, and in a month after the window switch is replaced, it still fails. Factory investigation found that car owners wash their cars every week and suspect that the windows are flooded, causing the switch to fail. The manufacturer installed rubber seals at the window switch, and the 1000 vehicle failure rate dropped from 100 to 10. Complaints were indeed reduced, but the 1000 vehicle failure rate remained as high as 10 vehicles.

Huabi's analysts found that the brand's window switches use comb electrodes. The grooves between the two poles contain chlorine, up to 10%. Hydrochloric acid is generated whenever water is encountered. Because the comb electrode is not cleaned, it causes chlorine. Chlorine element forms hydrochloric acid when it meets water vapor, hydrochloric acid forms electrolytic cell with positive and negative electrodes, and all oxidized corrosives are precipitated in the anode.

Liu Xuesen said, if not this failure analysis, who will control the residue of chlorine?

In October 2012, Huabi applied failure analysis technology to the field of forensic expertise, pioneering the application of domestic material evidence technology in the field of forensic expertise; in October 2013, Huabi established cooperative relations with property insurance companies such as PICC and Taibao to enter the field of insurance expertise; in December 2013, Huabi passed the national defense weapons and equipment research students. Produce three levels of confidential qualification examination and certification.

At present, Huabi has become the largest product quality technical appraisal and analysis service platform in China. Its service covers product quality appraisal, failure analysis, reliability detection, environmental and toxic and harmful substance detection and other fields. It has formed more than 100 professional and technical personnel such as forensic appraisers and authorized signatories, more than 1000 experts and laboratories. The area is 10000 square meters, and the total value of various professional appraisal instruments and equipment is over 100 million yuan.
