Beschreibung
Zusammenfassung:	The invention provides a bearing type preformed nano-silver film and a preparation method and application thereof.High-speed stirring and ultrasonic dispersion treatment are adopted, nano-silver powder is dispersed in a low-boiling-point dispersing agent, stable and dispersed nano-silver dispersion liquid is formed, a customized template (the pattern size can be customized) covers and is fixed to a film carrier, and the bearing type preformed nano-silver film is obtained. The nano-silver dispersion liquid is sprayed on a thin film carrier through an ultrasonic atomization spraying system, and finally the bearing type preformed nano-silver film (the silver content is larger than or equal to 99%) free of high-boiling-point organic auxiliaries is prepared; the bearing type preformed nano-silver film can realize preforming and low-temperature sintering, and has the characteristics of high sintering activity, no carbon residue on a large-area sintered joint, high heat conductivity coefficient, low voidage, conveni
