1. Introduction to Failure Analysis
BAIJIAN provides customers with various failure problems that occur during the production process, improving product quality and yield, and saving a lot of costs for product production and manufacturing. Over the years, we have accumulated rich experience in failure analysis through cooperation with many universities, automotive companies, and national engineers, and have a professional failure analysis team that specializes in metal I have rich experience and in-depth understanding of common fault situations and analysis solutions for non-metallic and electronic products 2. Steps for coating/plating failure analysis ① Background investigation: Failure background (failure overview, defect rate, service conditions (stress conditions and environmental description), design life and actual life (applicable to fracture failure), and other information), process flow (detailed description of production process flow) Product material specifications (mechanical properties, composition, hardness specifications, and other parameters) ② Propose an analysis plan: 1. Appearance inspection: microstructure observation (metallographic structure, inclusion analysis, carbide unevenness, coarse grain layer, decarburization layer, and other defect analysis) Non destructive analysis: C-SAM ultrasonic scanning, X-ray coating thickness analysis, etc Three destructive analysis: slice analysis, SEM/EDS composition analysis, red ink test, and other technical analysis ③ Preliminary Conclusion: A preliminary failure conclusion is obtained by combining various analytical methods such as physics and chemistry ④ Verification: Design simulation tests to reproduce failure phenomena and verify preliminary conclusions ⑤ Report: Based on the test results, create a comprehensive failure analysis report, identify the cause of the failure, and propose corresponding improvement suggestions Function of testing report:1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report 2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6. Industrial problem diagnosis: Verify the troubleshooting and correction of industrial production problems100% inspection and testing process:1. Telephone communication and confirmation of requirements 2. Recommend solutions and confirm quotations 3. Mail samples and arrange testing 4. Progress tracking and result feedback 5. Provide reports and after-sales service 6. If urgent or priority processing is requiredTesting and testing characteristics:1. The testing industry is fully covered, meeting different testing needs 2. Fully cover the laboratory and allocate localized testing nearby3. Engineers provide one-on-one services to make testing more accurate 4. Free initial testing, with no testing fees charged 5. Self service order delivery for free on-site sampling 6. Short cycle, low cost, and attentive service 7. Possess authoritative qualifications such as CMA, CNAS, CAL, etc 8. The testing report is authoritative and effective, and is generally used in China
