This standard specifies the performance to be evaluated, the testing methods to be used, and establishes unified requirements for various performance and dimensions. This standard applies to rigid flexible multilayer printed boards with through connections, regardless of their manufacturing method, and is intended to serve as the basis for signing agreements between the supply and demand parties. The term 'relevant specifications' used in this standard refers to such a protocol. This standard does not apply to flat cables. 2. The provisions included in the following standards constitute the provisions of this standard by reference in this standard. At the time of publication of this standard, all versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards.

Unless otherwise specified, all tests listed in Table 1 should be conducted. When special additional performance is specified in relevant specifications, additional test verification is required, and these related tests should be selected from Table 2. The additional detailed instructions for the test should be specified in the relevant specifications and indicated with "*" in the corresponding columns. These detailed instructions should comply with the provisions of IEC 60326-2. These tables are not intended to indicate the order of the tests, unless otherwise specified, the tests can be conducted in any order. The number of samples is specified by relevant regulations
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 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:
