Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 5230-1995 "Electrolytic Copper Foil". Compared with GB/T 5230-1995, the main technical changes of this standard are as follows.
---Added the terms and definitions of "elongation", "profile", "smooth surface" and "rough surface" (see Chapter 3).
---The model number has been increased from 2 to 5 (see 4.1, Table 1 of the.1995 edition).
---Added the copper foil code and mark (see 4.2, 4.3).
---Modified the length and width deviation of the sheet-shaped copper foil, from "the agreement between the supplier and the demander" to "the allowable length deviation is L 4.00 0 mm
The allowable width deviation is W 2.00 0 mm or agreed by the supplier and the buyer" (see 5.2.1, 5.2.2.2 of the.1995 edition).
---Modified the width deviation of the packaged copper foil, from the 4 width range section regulations to "the width allowable deviation is W 2.0 0 mm
Or it can be negotiated between the supplier and the buyer" (see 5.2.2, Table 3 in the.1995 edition).
---Increase the specifications of unit area mass and thickness, from 11 types to 16 types, increase the allowable deviation of unit area mass "high"
"Accuracy" grade (see Table 3, Table 2 of the.1995 edition).
---Added the copper foil profile type and profile requirements (see Table 4).
--- Modify the surface roughness requirements of copper foil (see 5.2.6, 5.7.3 of the.1995 edition).
--- Modify the physical properties of copper foil (see Table 5, 5.3 of the.1995 edition).
● E-01 foil. increase the tensile strength and elongation index of the thickness of 9μm and 12μm foil; compared to the original standard, increase the thickness
The tensile strength and elongation index of 18μm, 35μm, 70μm foil; the specific performance index of thickness 25μm foil is deleted,
Amended as "to be agreed between the supplier and the buyer."
● E-02 foil. Increase the tensile strength and elongation index of the thickness of 12μm foil; compared with the original standard, it has increased by 18μm, 35μm,
The tensile strength index of 70μm foil.
● Increase the tensile strength and elongation index of E-03, E-04, E-05 foil and the fatigue ductility index of E-05 foil.
---Added "etchability", "chemical cleaning", "processing transfer", "high temperature oxidation resistance" and "purity" requirements (see 5.4.1, 5.4.2,
5.4.4, 5.4.5, 5.5).
---Added 15μm copper foil mass resistivity regulations (see Table 6).
---Chapter 7 (Inspection Rules) has been revised, adding inspection classification, test conditions, identification inspection and quality consistency inspection items, sampling and
Judgment (see Chapter 7).
---Appendix A (informative appendix) "Comparison of Electrolytic Copper Foil Models at Home and Abroad" has been added (see Appendix A).
---Added Appendix B (Appendix to the specification) "Test Method for Copper Powder Diameter and Quantity" (see Appendix B).
---Appendix C (normative appendix) "Testing Method for Copper Foil Warpage" has been added (see Appendix C).
--- The 7 appendices of GB/T 5230-1995 have been deleted (see Appendix A, Appendix B, Appendix C, Appendix D, Appendix E,
Appendix F, Appendix G).
