Headlamp manufacturing plasma processing makes cold glue become the mainstream of the automotive industry

Headlamp manufacturing plasma processing makes cold glue become the mainstream of the automotive industry

When BGA packaging process is carried out by plasma cleaning machine, almost all automobile headlamps are made of adhesive to meet the requirements of glue leakage between the light distribution mirror piece and the housing, hot melt adhesive and cold adhesive. They have their own characteristics. The characteristics of hot melt adhesive: in a fluid state at a certain melting temperature, by the active glue machine active glue injection, cooling speed is fast, glue production force occupies a greater advantage, so suitable for mass production. Cold adhesive characteristics: in normal temperature conditions in the fluid state, under the condition of the condensation, naturally over time, the coalition force will be more and more strong, the manual glue, suitable for small batch production, the sealing effect is better than hot melt adhesive, but under the condition of the need to stand for 24 hours after the condensation, need tooling and process, production cycle is longer than hot melt adhesive moment. It is assumed that the cold adhesive can obtain both cheap and high quality adhesive effect with reasonable technology and its own price advantage. The pretreatment of the cemented surface by plasma treatment makes this result possible, while the processing equipment of plasma treatment of the cemented surface is at atmospheric pressure, which makes this process acceptable to the user in terms of production and capital investment. Gaseous plasmas with different chemical properties produce different functional properties, such as surface materials that are more hydrophobic or more hydrophilic. Atmospheric plasma equipment does not require a valuable vacuum system, which makes the cost of the equipment and operating costs easily acceptable to the user, and because it is operated at atmospheric pressure, it can be well integrated with existing production lines for continuous production. As a result of these characteristics, some domestic automotive lamp manufacturing enterprises with considerable research and development strength have begun to explore or apply this production mode.

Empirical analysis of graphene etching principle of plasma surface processor manufacturers

Empirical analysis of graphene etching principle of plasma surface processor manufacturers

The boundary defects of graphene wires are not well controlled at present, because the bond breaks of graphene are always along the 60° or 120° direction, which makes the boundary of the wires difficult to clean. This causes the graphene wires to form different widths in different regions, which is obviously very bad for chip scale manufacturing. For etching, this requires a much more aggressive end etching or post-processing process that does not damage the graphene thin lines. Other studies have shown that oxygen plasmas are more efficient for the etching of thick graphene. Oxygen plasmas are more efficient for the etching of litholene at a faster rate and are more effective for thicker layers of graphene. Graphics with lines and voids of 20μm were used to detect the etching effect. The graphene used in this study is 50nm thick and is grown on silicon dioxide. The etching conditions were a mixture of 70sccm oxygen and 30sccm argon, with a bias of 150W and a pressure of 55mT. The photoresistor used was the pattern obtained by twice spinning coated AZ4620 with a thickness of 20μm. The etching rate for graphene is about 100nm/min, while the etching rate for photoresists AZ4620 is 330nm/min, which also requires thicker photoresists or the use of a 3-layer mask structure. Fortunately, the etching rate for amorphous carbon under this condition is about 20nm/min, which can be used as the resistance layer for graphene etching. From the existing etching principle and experience analysis, mixing of oxygen plasma argon plasma not only ensure the strength of chemical etching can also be high bias to accelerate, with the heavier argon plasma bombardment graphene, ensure that the graphene films of relatively thick physical attacks, achieve etching, but apparently to remove residues, then it has no physical etching effect, And it will produce bombardment and damage to the film below. This means that a low bias oxygen plasma is used to complete the etching, which is both effective in removing the residue and protecting the underlying film. This scheme should be more efficient than using the main etching program to complete the etching, and get better graphics. The above is the CRF plasma surface processor manufacturers of graphene etching principle experience analysis.
