Abstract

The invention provides a metal-plastic composite film, a preparation method of the metal-plastic composite film, and an application of the metal-plastic composite film in the field of LCP substrate preparation. The metal-plastic composite film comprises sequentially stacked first metal foil material, polymer filling film, second metal foil material, adhesive layer and polymer release film. The above-mentioned metal-plastic composite film includes the first metal foil material, the polymer filling film, the second metal foil material, the adhesive layer and the polymer release film stacked in sequence. When the metal-plastic composite film is applied to the preparation of the LCP substrate, it only needs to provide The metal-plastic composite film, high-temperature buffer pad and mirror steel plate are three pressing auxiliary materials, which greatly reduce the number of stacked layers of auxiliary materials, thereby reducing errors and omissions and saving stacking time.

Description

【Technical field】 [0001] The invention relates to an LCP high-temperature pressing process, in particular to a metal-plastic composite film, a preparation method thereof, and an application of the metal-plastic composite film in the field of LCP substrate preparation. 【Background technique】 [0002] With the rapid development of 5G communications and millimeter waves, the demand for high-frequency and high-speed FPCs continues to increase. At present, the high-frequency substrates mainly used in the industry are mainly LCP substrates (liquid crystal polymer substrates), and the production of LCP substrates usually requires a high-temperature lamination process. [0003] The preparation of LCP substrates requires the use of corresponding auxiliary materials for lamination. At present, the main auxiliary materials selected for the preparation of LCP substrates are high-temperature cushions, mirror steel plates, metal foils, polymer filled films, and polymer release films.
