Process characteristics and application of DLC film in vacuum coating machine

The high-speed partial DLC film of the vacuum coating machine uses a special device to cover the parts that do not need the DLC film, and enables the plating solution to flow at a high speed on the surface of the coating, and uses a high current density to perform the DLC film process.

Vacuum coating equipment DLC film This process is characterized by high plating speed, and only electrodeposits where the coating is needed. The vacuum coating machine DLC film can improve production efficiency and save the metal to be plated, but the equipment cost is high. At present, the vacuum coating machine DLC thin film process is mainly used for high-speed local precious metal plating of electronic components.

①The vacuum coating machine must have suitable equipment for DLC film, and a DLC film device suitable for different parts to be plated (especially when continuous partial DLC film). This device must have good insulation for the non-plated surface of the parts, and no leakage of the plating solution. The plating solution flows evenly on the surface to be plated without dead corners. During continuous plating, the parts transfer and run smoothly. In addition, there should be circulating filtration system equipment for high-speed flow of plating solution, including filter pumps and flow meters.

②The process specification of high-speed DLC film should be selected. For this reason, a plating solution with a high main salt concentration is generally used, and sometimes additives that can increase the plating speed are added to increase the temperature of the plating solution, and pulse power is often used. Of course, conventional DLC film specifications can also be used, but the plating speed is limited.
