Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum composite copper-clad laminate technology, and in particular to a roll printing etching forming device for copper-aluminum composite copper-clad laminate. Background Technology

[0002] In the production of copper-aluminum composite copper-clad laminates, roll etching is the core process for preparing circuit patterns or specific textures. Its processing precision, efficiency, and finished product quality directly determine the application performance of the copper-clad laminate. Copper-aluminum composite copper-clad laminates combine the conductivity of copper with the lightweight advantages of aluminum and are widely used in the electronics and communications industries. However, due to the characteristics of its composite substrate, traditional roll etching equipment has gradually revealed many limitations in actual production, making it difficult to adapt to the high-precision and high-efficiency production requirements. Existing roll printing and etching equipment for copper-aluminum composite copper-clad laminates suffers from insufficient precision in adjusting roller printing pressure and gap. The adhesion between the printing roller and the substrate directly affects the clarity of the printing. Traditional equipment often uses manual adjustment of the printing roller position, which is inefficient and inaccurate, easily leading to blurred patterns or incomplete printing in certain areas. Furthermore, it cannot quickly adapt to copper-aluminum composite substrates of different thicknesses, increasing changeover time. The ink supply and transfer stability are also poor. Traditional ink supply methods, such as immersion or scraping, make it difficult to control the ink thickness evenly, resulting in uneven ink layer thickness on the substrate surface after printing, leading to over-etching or under-etching during subsequent etching. This also results in significant ink waste and increased production costs. Therefore, we propose a roll printing and etching equipment for copper-aluminum composite copper-clad laminates.
