1 Scope
This standard specifies the testing methods for lead to lead capacitance and lead load capacitance in semiconductor integrated circuit packaging. This standard is applicable to the measurement of lead to lead capacitance and lead load capacitance in ceramic, metal, and plastic packaging of semiconductor integrated circuits
2 Equipment and Equipment
2.1 Capacitance Meter
The capacitance meter is equipped with a shielded two probe method and two coaxial cables. Alternatively, the shielded four probe method can be used, but the four probes must be connected to two probes at the cable end.
. Both methods require that the diameter of the insulated wire used for shielding connections be greater than or equal to 1.0Function 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
