英文摘要Laser-induced forward transfer (LIFT) is of great interest for the material deposition in direct writing applications. The LIFT of silver nanopaste at a large transfer gap of 500 mu m is demonstrated for droplet printing. There is a linear relationship between the transfer threshold and ratio of film thickness to transfer gap (thickness-gap ratio). It can be clearly divided into three distinct categories from the morphological characteristic such as diameter, surface area, and volume of droplets at different thickness-gap ratios. Ratios equal to or less than 0.03 are classified into category I. Ratios between 0.04 and 0.1 and greater than 0.1 are classified into categories II and III, respectively. The larger the thickness-gap ratio, the smaller the diameter of transferred droplets. The paste transfer is accomplished by the formation of a stable jet between the paste film and acceptor substrate at a large transfer gap. The top morphology of transferred droplets with dome-shaped and obvious tip are observed at and above the transfer threshold, respectively, which can be explained by different break-up locations of the jet. It is of great importance to provide reference for potential commercialization of microstructure fabrication by LIFT of paste, especially under large tolerance to transfer gap.
