ULTRATHIN DEVICE, MANUFACTURING METHOD THEREFOR AND USE THEREOF

Abstract: an ultrathin device, manufacturing method therefor and use thereof. the method includes: granulating a mixture containing raw material powder, an adhesive and a solvent into particles by spray drying to obtain first precursor, the raw material powder including metal material powder and/or ceramic material powder, a surface mean diameter of the raw material powder ranging from 1 �m to 15 �m, a mass ratio of the raw material powder to the adhesive ranging from 100:1 to 100:10, a surface mean diameter of the first precursor ranging from 40 �m to 80 �m, and flowability of the first precursor being lower than 30 s/50 g; performing shaping process on the first precursor to obtain second precursor having a preset shape; and performing heat treatment on the second precursor to obtain the ultrathin device with a thickness smaller than or equal to 1 mm. the thickness is reduced without having a significant impact on the mechanical properties.
