Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13556-1992 "printed circuit with flexible copper clad polyester film." This standard compared with GB/T 13556-1992, the main changes.

--- The standard name changed to "flexible printed circuit with polyester film CCL";

--- Added Chapter 3 terms and definitions;

--- Chapter 4 defines the product classification, logo and structure, an increase of flame-retardant type of product;

5.2 increased the thickness of the adhesive layer and tolerance requirements, delete GB/T 13556-1992

3.3 in the copper foil and polyester film The recommended combination of programs;

6.1.1 respectively, the copper foil surface, the basement membrane surface and the secondary surface requirements;

6.1.2 increased product size and tolerance requirements;

6.2 to improve the product peel strength, dimensional stability, bending fatigue performance requirements; Remove the GB/T 13556- 1992 Table 6 requirements for retention of peel strength after immersion and simulated plating conditions; increased thermal stress (floating Welding), solderability, folding resistance, chemical resistance, water absorption requirements; Flame retardant type of products increased combustion requirements;

--- Chapter 8 added a roll of product joints and core tube requirements;

--- Added Chapter 9 ordering documents requirements. Please note that some of this document may be patentable.

1 Scope

GB/T 13556-2017 is the Chinese national standard on copper-clad polyester film laminates for flexible printed circuits, in the field of electronics. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2019. Classification: ICS 31.180, CCS L30. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the terminology, classification, requirements, inspection rules, packaging, marking, transportation and storage of polyester film CCL for flexible printed circuit Save and so on. This standard applies to flexible printed circuit with polyester film CCL (hereinafter referred to as flexible polyester CCL).
