Abstract Scope |
The micro-cold spray process is a direct-write process that allows thick films to be deposited at room temperature by impacting nano-sized particles at velocities exceeding 1000 m/s. This technique allows for additive manufacturing on heat-sensitive substrates such as printed circuit boards. This study explores the deposition of silver particles using the micro-cold spray process. The effects of nozzle diameter and nozzle to substrate distance on silver deposits is also studied. Both of these variables affect the particle impact velocity and the breadth of the deposit. Parameters that are of interest include the deposit line width, the film density, film adhesion, electrical conductivity, and the film microstructure. |
