GJB 362C和GJB 7548A的实施应用

Analysis on implementation and application of GJB 362C and GJB 7548A

GJB 362 《刚性PCB通用规范》和GJB 7548 《挠性PCB通用规范》是军用印制电路板(PCB)领域的两项重要标准,在实施后,很多使用者对标准的理解和应用还存在一些疑问。主要介绍两项标准修订的基本情况、对标准实施应用的见解和对标准内容的理解,以及存在的问题,希望能够帮助从业者加强对标准的理解与应用,同时也希望军用PCB的设计、制造和使用方对标准的认识能够达成一致,让标准帮助大家解决工作中遇到的相关问题。

GJB 362 General Specification for Rigid PCB and GJB 7548 General Specification for Flexible PCB are two important standards in the field of military printed circuit board(PCB).In the promulgating of GJB 362C—2021 and GJB 7548A—2021,many users still have some questions about the understanding and application of the standards.This paper mainly introduces the basic situation of the revision of the two standards,and the author's understanding of the application of the standards,the understanding of part of the standard and existing problems.We hope to help practitioners strengthen the understanding and application of the standard,and hope that the designer,manufacturer and user of military PCB can reach the same understanding of the standards,so that they can help everyone solve the relevant problems in the work.
