Characteristics of Targeted Metal Etching Process

The metal etching process, like other processes, also has its own characteristics. Only with a full understanding of the characteristics of the metal etching process can the required process be designed. The characteristics of the metal etching process are mainly manifested in 10 aspects, including targeting, internalization, integrity, dynamism, hierarchy, structure, operability, manageability, stability, authority, and enforceability. The following analysis and discussion will focus on these elements.

1. Goal oriented

The so-called purposefulness refers to having a clear output throughout the entire process of a certain technological process, or in other words, achieving a specific goal. For metal etching, the purpose is to meet the requirements of its design drawings for the product. More specifically, these

Requirements include etching size requirements for the product, surface roughness requirements after etching, etc.

For example, for decorative graphic etching products, the goals to be achieved after being processed and produced through the designed process flow are: ① requiring high clarity of the etched graphic and text; ② Require the surface roughness of the metal after etching to meet the design requirements; ③ Require the etching depth of graphics and text to meet the design requirements; ④ The deformation of the workpiece during the etching process should be within the range specified in the design; wait.

For example, for products with structural purposes, the goal to be achieved after being processed and manufactured through the designed process flow is: ① Whether the etching depth of the workpiece after etching is within the tolerance range specified in the design; ② Whether the actual size of the workpiece after lateral etching after etching is within the tolerance range specified in the design, and whether the surface roughness of the workpiece after etching meets the design requirements, etc.

From the above two examples, it can be seen that different products have different final requirements. This requires proposing key process control points and control methods when designing the process flow, in order to ultimately ensure that the products processed through the designed process flow can achieve the design goals. Dongguan Huazhou Machinery Metal etching equipment provides a comprehensive solution.
