Factory Cheap Brass Metal Strips - Super Thick ED Copper Foils – CIVEN Detail:

Product Introduction

The ultra-thick low-profile electrolytic copper foil produced by CIVEN METAL is not only customizable in terms of copper foil thickness, but also features low roughness and high separation strength, and the rough surface is not easy to fall off powder. We can also provide slicing service according to customers’ requirements.

Specifications

CIVEN can provide ultra-thick, low-profile, high-temperature ductile ultra-thick electrolytic copper foil (VLP-HTE-HF) from 3oz to 12oz (nominal thickness 105µm to 420µm), 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 brand super-thick electrolytic copper foil is equiaxed fine crystal spherical; while the grain structure of similar foreign products is columnar and long.

● CIVEN ultra-thick electrolytic copper foil is ultra-low profile, 3oz copper foil gross surface Rz ≤ 3.5µm; 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 PP 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.
