     铜箔是制造印刷电路板的关键导电材料，按照不同的制造工艺可分为电解铜箔和压延铜箔两大类  

（1）压延铜箔(Rolled Copper Foil) 是将铜板经过多次重复辊轧而制成的原箔(也叫毛箔)，根据要求进行粗化处理。

由于压延铜箔加工工艺的限制，其宽度很难满足刚性覆铜板的要求，所以压延铜箔在刚性覆铜箔板上使用较少。

     由于压延铜箔耐折性和弹性系数大于电解铜箔，故适用于柔性覆铜箔板上。 

 (2)电解铜箔(Electrode Posited copper)是将铜先经溶解制成溶液，再在**的电解设备中将硫酸铜电解液在直流电的作用下，电沉积而制成原箔，

然后根据要求对原箔进行表面处理、耐热层处理及防氧化处理等一系列的表面处理。电解铜箔不同于压延铜箔，电解铜箔两面表面结晶形态不同，紧贴阴极辊的一面比较光滑，称为光面；另一面呈现凹凸形状的结晶组织结构，比较粗糙，称为毛面。

电解铜箔和压延铜箔的表面处理也有一定的区别。

     由于电解铜箔属柱状结晶组织结构，强度韧性等性能要逊于压延铜箔，所以电解铜箔多用于刚性覆铜板的生产，进而制成刚性印制板1015037276_1854488873

Copper foil is a key conductive material for making printed circuit board, which can be divided into electrolytic copper foil and rolled copper foil according to different manufacturing process

(1) the Rolled Copper Foil is the original Foil (also called wool Foil) made from the repeated rollers of the Copper plate, and roughened it according to the requirements.

Due to the limitation of the copper foil processing technology, the width of the copper foil is difficult to meet the requirement of rigid copper plate, so the copper foil is used very rarely on the rigid coated foil.

Because the compressibility and elastic coefficient of the copper foil is greater than that of electrolyte copper foil, it is suitable for the flexible coating of copper foil. 

(2) electrolytic copper foil (a) is to dissolve the copper before it is dissolved into a solution, and then, in a special electrolytic device, the copper sulfate electrolyte can be deposited into the original foil under the action of direct current.

Surface treatment, heat resistance layer treatment and oxidation treatment of the original foil are then required.The electrolytic copper foil is different from the rolling copper foil, which is different from the two surfaces of the copper foil, and the side of the cathode roller is smooth, which is called the smooth surface.

The other side presents the structure of the crystallographic structure of concave convex shape, which is relatively rough, called the hairy surface.

There are some differences in the surface treatment of electrolytic copper foil and rolled copper foil.

Due to the structure of the structure of the column of electrolytic copper foil, the properties of strength and toughness are inferior to that of rolling copper foil, so the electrolytic copper foil is used for the production of rigid copperplate, which can then be made into a rigid printing plate.

Is a kind of metal tape, copper foil tape is mainly used in electromagnetic shielding, divide into two kinds, ** shielding and magnetic shielding ** shielding mainly depend on the excellent electrical conductivity copper itself, and magnetic shielding requires the adhesive surface of the conductive copper foil tape material "nickel" to achieve the effect of magnetic shielding, and therefore is widely used in mobile phones, laptops and other digital products.

The general inspection performance of the most commonly used copper foil tape on the market is as follows: material: CU 99.98%

Product description: purity is higher than 99.95%, and its function is to eliminate EMI interference, isolate electromagnetic wave to human body injury, avoid not need voltage and current to affect function.

In addition, it has good effect on static discharge after grounding.

Strong pasting and conductive properties can be cut into various specifications according to customer's requirements.

The way: applicable to all kinds of transformer, cell phone, computer, PDA, PDP, LCD monitor, laptop computer, photocopier, etc.

The general inspection performance of the most commonly used copper foil tape on the market is as follows: material: CU 99.98%

Base material thickness: 0.007 mm - 0.075 mm

Adhesive thickness: 0.015mm ~ 0.04 mm

Colloidal components: ordinary pressure sensitive adhesive (not conducting) and conductive pressure sensitive adhesive

Stripping force: 0.2 ~ 1.5kgf / 25mm (180 degree reverse stripping force test)

Temperature tolerance - 10 ℃ -- 120 ℃

Tension strength of 4.5 ~ 4.8 kg/mm

Elongation is 7% ~ 10% MIN

 

1. The test conditions for room temperature 25 ℃, relative humidity below 65 ℃ by the United States ASTMD - 1000 test results.

2. When the goods are kept, please keep the interior dry and ventilated. The domestic copper is usually kept for 6 months, and the importing country can be kept for longer

3. The products are mainly used to eliminate EMI of EMI, and isolate the harmful effects of electromagnetic waves on the human body. It is mainly used in computer peripherals, computer monitors and transformer manufacturers.

4. Copper foil tape is divided into single - sided and double - side coating.

Single cladding of the copper foil tape is divided into single guide copper foil tape and double guide copper foil tape, single surface copper foil tape which glue is not conductive, only another side of copper conductive, so called single single-sided conductive namely;

Double - lead copper foil tape refers to the conductive surface of the coated surface, and the other side copper itself conducts electricity, so it is called double conductance.

And cladding of the copper foil tape used for other materials and processed into more expensive composite material, double-sided coated copper foil the adhesive surface are conductive and non-conductive. Customers can choose according to their demand for conductive.
