China Cheap price Pure Copper Sheet - VLP ED Copper Foils – CIVEN
China Cheap price Pure Copper Sheet - VLP ED Copper Foils – CIVEN Detail:
Product Introduction
The very low profile electrolytic copper foil produced by CIVEN METAL has the characteristics of low roughness and high peel strength. The copper foil produced by the electrolysis process has the advantages of high purity, low impurities, smooth surface, flat board shape, and large width. The electrolytic copper foil can be better laminated with other materials after roughening on one side, and it is not easy to peel off.
Specifications
CIVEN can provide ultra-low profile high temperature ductile electrolytic copper foil (VLP) from 1/4oz to 3oz (nominal thickness 9µm to 105µm), and the maximum product size is 1295mm x 1295mm sheet copper foil.
Performance
CIVEN provides ultra-thick electrolytic copper foil with excellent physical properties of equiaxial fine crystal, low profile, high strength and high elongation. (See Table 1)
Applications
Applicable to the manufacture of high-power circuit boards and high-frequency boards for automotive, electric power, communication, military and aerospace.
Characteristics
Comparison with similar foreign products.
● The grain structure of our VLP electrolytic copper foil is equiaxed fine crystal spherical; while the grain structure of similar foreign products is columnar and long.
● Electrolytic copper foil is ultra-low profile, 3oz copper foil gross surface Rz ≤5µm; while similar foreign products are standard profile, 3oz copper foil gross surface Rz > 3.5µm.
Advantages
● Since our product is ultra-low profile, it solves the potential risk of the line short circuit due to the large roughness of the standard thick copper foil and the easy penetration of the thin insulation sheet by the “wolf tooth” when pressing the double-sided panel.
● Because the grain structure of our products is equiaxed fine crystal spherical, it shortens the time of line etching and improves the problem of uneven line side etching.
● while having high peel strength, no copper powder transfer, clear graphics PCB manufacturing performance.

Note: 1. The Rz value of copper foil gross surface is the test stable value, not a guaranteed value.
2. Peel strength is the standard FR-4 board test value (5 sheets of 7628PP).
3. Quality assurance period is 90 days from the date of receipt.
