The present invention discloses a method for improving the liquidity of a viscoelastic fluid via high frequency ultrasounds. High frequency ultrasonic waves are introduced into the viscoelastic fluid by utilizing an ultrasound amplitude-change pole supplied with power by an ultrasonic power supply to generate a large amount of bubbles, and the bubbles are detonated by shear movement generated by the ultrasonic amplitude-change pole, so that molecular chains wound together are scattered, the viscoelasticity of the viscoelastic fluid is lowered, and the fluidity of the viscoelastic fluid is improved. The method lowers the viscoelasticity of the fluid by way of scattering the molecular chains wound together, but does not change the molecular structure, therefore, the chemical property of the fluid is not changed; Scattered molecular chains can be recovered in the winding state along with Brownian motion step by step after being poured, so that the high viscoelasticity of the viscoelastic fluid can be recovered, and connected channels are better protected. The method lowers the viscoelasticity of the viscoelastic fluid on the basis of the high frequency ultrasonic shear movement without high temperature, as a result, extra thermal stress and transformation are not introduced into a chip in a pouring process.
