Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 14708-1993 "flexible printed circuit with polyester film," compared with the GB/T 14708-1993 main
Technical changes are as follows.
--- Added Chapter 3 terms and definitions;
--- Chapter 4 increased the product classification, marking examples and structure of the content of the preparation;
--- Increased thickness and tolerance requirements in 6.2.3;
--- 6.3 in the volatile content of the performance requirements can be modified for the optional technical requirements;
--- 6.3, with peel strength instead of dry peeling peel strength after dry treatment requirements, an increase of chemical resistance, thermal stress (floating
Welding), water absorption, volume resistivity and electrical strength requirements;
--- In Chapter 7, delete the bending fatigue test method, volatile content and fluidity of the test method is modified to reference
GB/T 14709-2017 in Appendix A, B, in the dimensional stability test method to increase the dimensional stability of the release layer operation
Make steps
--- In 7.2, adjusted the original test items group, the original standard in the A group, B group test combined into A group test, the C group
The test (3 months to 6 months) is divided into group C (3 months) and group D (12 months), the specific test cycle is shown in Table 7;
--- 9.2 increase in the joint or unqualified segment size requirements.
This standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
