Introduction of HVMP Hybrid Vacuum Coating Process
What is HVMP hybrid vacuum coating？
HVMP (Hybrid Vacuum Metallization Process) includes PVD and PECVD processes. As the industry continuously seeks to reducing production costs, shortening process time, reducing environmental pollution, and reducing energy consumption, new HVMP technologies have been developed to solve the current problems. The traditional process uses spraying and dipping to change the surface appearance and physical properties of the substrate, but there are many steps, which not only require a leveling time, but also a thermal baking method to cure the film, which will cause an uneven film thickness.
Introduction to HVMP Hybrid Vacuum Coating Process
The PVD process of HVMP is mainly performed using thermal evaporation, in a high vacuum environment. The plating material is heated, so that the plating material atoms evaporate to reach and adhere to the surface of the substrate. During the evaporation process, the evaporated atoms gain enough energy to move freely on the surface of the substrate, stack the atoms to form nuclei, and then aggregate to form an island-like structure, so that a uniform film can be formed.
The plasma-enhanced chemical vapor deposition (PECVD) technology of HVMP is the basic method of material surface modification and film deposition. The high vacuum environment provides, high quality, low impurity characteristics for the coating press. The PECVD process injects a viscous flow of thin film into the chamber cavity and uses plasma to dissociate the monomer to be deposited onto the surface of the workpiece. This technology is low temperature deposition with high bonding strength, controllable film thickness and good composition structure.
Advantages of HVMP Hybrid Vacuum Coating Process
The new R&D of HVMP technology combines the advantages of PVD and PECVD, successfully completing the two processes in the same chamber cavity for multi-layer coating, reducing traditional complicated steps, improving product yield, shortening process time, and saving traditional thermal baking. This new generation of manufacturing equiment has less energy consumption and greatly reduces production costs to meet current industrial process requirements.
