GB/T 16315-2017Polymide woven glass fabric copper clad laminated sheets for printed circuits (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 16315-1996 "printed circuit with a limited flammability of copper clad polyimide glass cloth laminate" and GB/T 16317-1996 "multi-layer printed circuit with a limited flammability of the copper-clad polyimide glass cloth laminate," and GB/T 16315-1996 and GB/T 16317-1996 compared to the main technical changes are as follows:

--- CPIGC-61F glass transition temperature from.200 °C to.200 °C ~ 250 °C (see Table 1);

--- Increased 915mm × 1220mm, 1020mm × 1220mm, 1065mm × 1280mm, 1065mm × 1155mm, 1220mm × 1245mm five recommended board size specifications (see Table 2);

--- Increased 0.05mm ~ 0.10mm, 0.10mm ~ 0.15mm, 0.15mm ~ 0.30mm, 0.3mm ~ 0.5mm four Nominal thickness specifications; Increased C-class thickness tolerances for various nominal thickness specifications in the

0.05 mm to

6.4 mm range Standard (see Table 4);

--- "Bow and twist" instead of "warpage" and improve the indicators (see Table 5);

--- "Water absorption" instead of "water absorption", "surface resistivity" instead of "surface resistance"; Remove the "pull-off strength" "Copper foil resistance" "Surface corrosion" "edge corrosion" indicators; increased breakdown voltage, arc resistance, high temperature bending strength and thermal expansion coefficient, heat Decomposition temperature, thermal stratification time (see Table 6);

--- Improve the bending strength, flammability, peel strength, water absorption, dielectric constant, dielectric loss factor and other performance indicators (see Table 6);

--- Added references. This standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

1 Scope

GB/T 16315-2017 is the Chinese national standard on polymide woven glass fabric copper clad laminated sheets for 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 31 July 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 February 2018. 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 printed circuit with copper foil polyimide glass fiber cloth laminate (hereinafter referred to as CCL) product classification, technical requirements, Test methods, quality assurance requirements, packaging, marking, transport and storage requirements. This standard applies to modified or unmodified polyimide resin as a binder, E glass fiber cloth as a reinforcing material made of a thickness of 0.05mm ~ 6.4mm CCL.
