Excellent conductivity and thermal conductivity PET film with single-sided copper plating or double-sided copper plating on PET film

PET copper plated filmIt is a technology of vacuum nano coating on PET base film, using copper with a purity of 99.999% as the target material, and then depositing a metal copper film on its surface by changing the working pressure, temperature, and evaporation time in the vacuum chamber. Combining the performance of PET film with the conductivity and thermal conductivity of copper. You can choose single-sided copper plating orDouble sided copper plating.

hangCopper electroplating usually requires a base layer of nickel plating to isolate the copper base and prevent the color of the copper from appearing after heating. Copper electroplating generally refers to two types: one is to electroplate the product with copper or copper alloy on its surface, and the other is to use the principle of electrolysis to deposit bright copper on certain metal surfaces;
Copper plating, as a cathodic coating, does not have anti-corrosion effect in the presence of pinholes. It can only have anti-corrosion effect in the absence of pinholes when the thickness exceeds 5 microns. Its true function is to brighten and level, making the entire coating look brighter and fuller.

Under certain acidity and temperature, nickel ions in the solution are reduced to atoms by sodium dihydrogen phosphate and deposited on the surface of the workpiece, forming a fine and bright nickel coating. Steel workpieces can be directly coated with nickelNickel tin copper platingCopper alloy parts need to be in contact with aluminum sheets on their surface for 13 minutes to accelerate electroless nickel plating;
Electroplated bronze, brass parts dyed black antique, antique green, and directly polished gold explosion formula and operation skills. Firstly, the formula and operation skills for electroplating bronze and brass parts dyed black include arsenic acid 125 gL, copper sulfate 62 gL, and room temperature water added to 1L. Note that after preparing this black dyeing solution, it needs to be parked for 24 hours; Copper electroplating aims to achieve functions beyond the properties of copper, such as tin plating to prevent oxidation, gold and silver plating to increase conductivity, etc;
Preventing rusting of water pipe copper parts is not achieved through the use of pure copper. Generally, half copper and half other materials are used. Electroplating is done to prevent rusting of water pipe copper parts caused by reactions between non pure copper and other substances;
1. Measuring electrode electromotive force does not necessarily require pure copper. Depending on the requirements of different methods, zinc electrodes, copper electrodes, calomel electrodes, and others are available
2. You mentioned that before copper plating, the electrodes were sanded with coarse and fine sandpaper to remove themElectroplating materialsThe surface oxide layer and increasing the surface area of the electroplating material can achieve better results; Don't listen to anyone's answer above. The main reason why brass is plated with copper before tin plating is because brass contains many impurities, especially zinc alloy. After tin plating, the zinc alloy will penetrate, which will result in poor weldability and coating appearance of future products. Nowadays, most products need to be pre plated with alkali copper or acid copper, and there are also pre plated with nickel.
