Component Reliability Improvement Certification for Electronic Components

Failure analysis of electronic components
Basic introduction
The rapid development of electronic component technology and the improvement of reliability have laid the foundation for modern electronic equipment. The fundamental task of component reliability work is to improve the reliability of components. Therefore, it is necessary to attach importance to and accelerate the development of component reliability analysis work, determine the failure mechanism through analysis, find out the cause of failure, and feedback to design, manufacturing and use, jointly study and implement corrective measures to improve the reliability of electronic components.
The purpose of failure analysis of electronic components is to confirm the failure phenomenon of electronic components with the help of various test analysis techniques and analysis procedures, distinguish their failure mode and failure mechanism, confirm the final cause of failure, and put forward suggestions for improving design and manufacturing processes to prevent the recurrence of failure and improve component reliability.
Service objects
Component manufacturers: deeply involved in product design, production, reliability testing, after-sales and other stages, and provide customers with theoretical basis for improving product design and process.
Assembly plant: divide responsibilities and provide basis for claims; improve production process; screen component suppliers; improve testing technology; improve circuit design.
Device agent: distinguish quality responsibility and provide basis for claims.
Machine users: Provide a basis for improving the operating environment and operating procedures, improve product reliability, establish corporate brand image, and improve product competitiveness.
Significance of failure analysis
1. Provide a basis for electronic component design and process improvement, and guide the direction of product reliability work;
2. Identify the root causes of electronic component failure, and effectively propose and implement reliability improvement measures;
3. Improve the yield rate and reliability of finished products, and enhance the core competitiveness of the enterprise;
4. Clarify the responsible party for product failure and provide a basis for judicial arbitration.

About Us

Shenzhen LCS Compliance Testing Laboratory Ltd., abbr. for LCS, was founded in 2004 in Shenzhen, LCS is now growing into an independent comprehensive third-party institution which focuses on test & certification. Profound technical background and diligent working attitude decided LCS with an outstanding high starting point from the outset，pioneering spirit and consciousness of keeping pace with the times which predestined the thoroughly tempered course of LCS.

Our Labs

LCS Founding Members have engineering background and had gradually built up Safety Lab, EMC Lab, RF Lab, SAR & HAC Lab, Reliability Lab, Lighting Electrical Lab, LED Lighting Performance Lab, Energy Efficiency Lab, Electronic Cigarette Testing Lab, Chemistry Lab, BQTF, Environmental and Occupational Evaluation Lab, Battery Lab, Toy Lab, Textile Lab, Food and Food Grade Material Lab. The establishment of our comprehensive labs ensure our test and certification scope covers almost all fields, such as Reliability and Safety test, EMC test, Chemical Hazardous Substances test, Material Analysis, Food Contact Material test, Bluetooth Test & Certification, Environment and Occupational Health, Performance test of spare parts of Automobile and so on.

Authorization

Moreover, LCS won many authorized qualifications both domestic and overseas. LCS is recognized as IEC/ISO17025 laboratories accepted by CNAS and NVLAP, accredited by CPSC, CMA, accredited for CQC, ISTA, CBTL, SASO, SABS. Meanwhile LCS become laboratory authorized by TUV, BQTF issued by the SIG. LCS had also signed cooperation agreements with FCC, ISED, ETL, CEC, UL, E-Mark, CETECOM, KTC, SAA Approval and many other authoritative institutions, hence we can provide our clients with efficient and professional service for product test and certification.
