  • Failure Analysis of Electronic Components

    The introductionThe rapid development of electronic components and its reliability laid the foundation for modern electronic equipment industry, more attention should be paid to thereliability analysis works.By analyzing the failure mechanisms, finding out the failure causes, feeding back the conclusions, researching and carrying out the corrective actions, the reliability of electronic components can be improved.The purposes of failure analysis for electronic components are to confirm the failure phenomenon, to distinguish the failure mode and failure mechanism, to find out the root cause, to make recommendations for improving the design and manufacturing process, to prevent failure recurring and finally to improve the reliability. Our customersParts Manufacturers Deeply involved in the phasesof design, produce, reliability testing and aftermarket, provide customers the theoretical basis of how to improve product design and process.Assembly plantsDivide responsibilities and provide the claims basis, improve production process, screening component supplier, improve testing technology and circuit design.Devices DealerDistinguish quality responsibility and provide the claimsbasis.Machine usersProvide the basis for improving operating environment and procedures, improve the reliability, establish a corporate brand image and enhance the competitiveness of enterprises. Your benefitsProvide the basis for design and process improvements, guide direction of reliability worksFind out the root cause of failure, propose and implement measures to improve reliabilityImprove product yield and reliability, enhance the core competitiveness of enterprisesClear the responsible party, provide the basis for judicial arbitrate Main failure mechanismsOpen circuit, short circuit, burned, leakage, functional failure, electrical parameter drift, unstable failure. Common techniquesElectrical test1.Connectivity test2.Electrical tests3.Function testsNon-destructive techniques1.X-Ray2.CT Scans3.C-SAMSample preparation techniques1.De-Cap (mechanical De-Cap, chemical De-cap)2.DE passivation layer (Chemical etching, plasma etching)3.Microanalysis technique (FIB, CP)Microscopic morphology techniques1.Optical microscopy2.SEMFailure Point Positioning technology1.Thermal Imaging Microscopy (hot spot)2.LCD hot spot detection technology3.Light emission microanalysis (EMMI)Surface Elemental analysis1.SEM/EDS2.AES3.XPS4.SIMS
  • Polymer Materials

    1.AbstractPeople are constantly put forward various new requirements on the polymer materials as the development of production and science technology. On the whole, the general development trend of technology of polymer materials in the future are high-performance, high functional composite, and intelligent and green. Customer demands for high product and process understanding is different because of the high technology of the new requirements and product requirements. Fracture, cracking, corrosion, discoloration, and so on phenomena occur frequently on polymer material, which often cause the responsibility of the dispute between supplier and user, so lead to a serious economic loss. Then more and more enterprises and units has a new demand for failure analysis of polymer material, which is no longer direct replace material by the previous conventional means, and need to find the root cause and its mechanism of the failure by means of failure analysis method, to improve product quality, process improvement and responsibility to arbitration etc. 2.Service objectPolymer materials manufacturers: in-depth product failure may cause the design, production, process, storage, transportation and so on stage, explore its failure mechanism, to improve product yield and provide basis for optimizing production processes.Assembly plant: responsibility for arbitration; Improve assembly process; To help suppliers terms of the quality of incoming material inspection.Distributors or agents, to provide favorable evidence for the quality responsibility, the responsibility for justice.The machine user: improve product technology and reliability, improve the core competitiveness. 3.Produce benefit1) It can find out fundamental failure reasons for polymer material, and effectively propose improving suggestions for products design and process;2) It can provide improving suggestions for products and process; improve products yield and reliability as well as enhance product competitiveness;3) It can clearly confirm the responsible party of product failure and provide the basis for the judicial arbitration. 4.Main failure mode (but not limited to)Fracture, cracking, corrosion, stratification, bubble, coating shedding, discoloration, abrasion failure etc.
