Well-designed Tinned 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.
