This standard is equivalent to the International Electrotechnical Commission's Quality Assessment System for Electronic Components standard IEC/PQC 90 "Sectional Specification for Single and Double sided Printed Boards with Metallized Holes" (1990 edition). 1. Overview: IEC 326-5 is the IEC standard for single and double-sided printed boards with metallized holes. The following documents include this IEC standard and the necessary supplementary standards for preparing printed boards for evaluation according to the Electronic Component Quality Assessment System of the European Commission for Electrotechnical Standardization (CENELEC). These standards are consistent with the GB/T 162611996 "General Specification for Printed Boards". 1.1 Scope and Purpose This document is a sectional specification (SS) for single and double-sided printed boards with metallized holes. When preparing to install components, it is not necessary to consider their manufacturing methods. This specification specifies the performance and testing methods evaluated by capability approval testing and quality consistency inspection (batch by batch and cycle by cycle). 1.2 Relevant documents IEC 68- Basic environmental testing procedures IEC 194 Terminology and definitions for printed circuits IEC 249 Metal foil substrates for printed circuits IEC 321 Design and use guidelines for components used in printed board installation IEC326-2 Test methods for printed boards IEC 326-3 Design and use of printed boards GB/T 16261-1996 General specification for printed boards GB/T 4588.1-1996 Sectional specification for single and double sided printed boards without metallized holes 2 General principles and this sub specification (SS) Suitable for single and double sided printed boards with metallized holes, it is also the basis for formulating the following detailed specifications-- The Capability Detailed Specification (CapDS) applies to the specialized materials and capability approval procedures specified in IEC 249-2. If necessary, each material should have a CapDS. CapDS can be developed by international or national institutions or manufacturers
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:
