Introduction to manufacturers of lead frame etching machines: What are the uses of etching processing

Etching processing is mainly customized processing of metals, also known as metal corrosion processing. The scope of application includes electronics, communication, automotive engineering, etc. What is the specific purpose of etching processing? Let the lead frame etching machine manufacturer briefly introduce it to you.

1. Remove burrs. Due to the presence of burrs on the end faces or edges of stainless steel plates during punching or mechanical processing, it not only affects the appearance of the product, but also affects the effectiveness of the machine. If mechanical polishing or manual desulfurization is used, not only is the efficiency low, but it cannot meet the design of rounded corners. Special chemical polishing or electrochemical polishing solutions are used to corrode the burrs, which does not affect surface completion and even improves surface smoothness. This is a combination of surface treatment and mechanical processing.

2. Remove excess dimensions. For example, the required wire diameter for stainless steel spring wire is 0.8~0.84, while the actual wire diameter is 0.8~0.9. How to achieve a uniformity of 0.8~0.84 in the finished product, and how to remove burrs and oxide films generated during the processing and heat treatment? If mechanical polishing and pliers repair methods are used to remove burrs, oxide scales, and uniformly remove 0.06-0.1mm from the circumference of the steel wire diameter, not only is the processing technology poor and the efficiency low, but the processing quality is also difficult to guarantee. By using a specialized chemical polishing solution, burrs and oxide scales can be removed simultaneously, and excess wire diameter can be uniformly removed. For example, for some sheet-like stainless steel parts, if the size is large, a special solution of electrochemical polishing can be used to reduce the thickness to meet the product size requirements.

3. Milling and cutting processing. Expose the parts of stainless steel material that need to be processed to chemical milling fluid for milling processing, so as to obtain parts of a certain shape or size, achieving the purpose of three-dimensional and decorative. By using screen printing, text, patterns, and designs can be chemically milled onto the surface of stainless steel products.
