1.1 Topic Content
This standard specifies the methods and general procedures for conducting failure analysis of semiconductor discrete devices in the laboratory. 1.2 Scope of Application
This standard is applicable to the failure analysis of semiconductor discrete devices (hereinafter referred to as devices). 1.3 Application Guidelines
When conducting failure analysis, the failure analysis method and program to be used should be determined based on factors such as the type, structure, failure mode, and failure mechanism of the failed device. The failure analysis program provided in this standard allows analysts to conduct failure analysis work based on it, and they can also modify the analysis program appropriately according to actual work conditions to achieve the analysis purpose

Definition
3.1 Defects
Any inconsistency with detailed specifications in terms of appearance, assembly, function, or process quality.
. 3.2 Screenable defects Screenable defects that can be eliminated using screening and inspection methods. 3.3 Batch related defects are defects caused by the design and manufacturing process and repeated in the same batch of devices. 3.4 Latent defectsFunction 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 problemsBaijian 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
