[0002] During the impregnation process of polyimide semi-cured sheets for aerospace printed circuit boards, when the polyimide resin solution is fed from the glue mixing working tank to the glue applicator for impregnation, the remaining glue after the polyimide resin solution and the glass fiber cloth are infiltrated will overflow from the impregnation glue basin back to the glue mixing working tank (feeding tank), and the polyimide resin solution forms a circulation process in the working tank and the impregnation glue basin. During the impregnation process, the polyimide resin solution will be consumed, and volatile raw materials such as solvents will also be volatilized and consumed. The consumption of solvents will increase the viscosity of the imide resin solution and affect the impregnation and bonding with the glass fiber cloth.
