Abstract:
1. A printing method comprising: heating a first surface of a first mounting portion to a predetermined first temperature before a semiconductor device is mounted on the first surface of the first mounting portion; mounting the semiconductor device on the first surface of the first mounting portion; discharging droplets of a liquid curable by active light rays from a nozzle of a discharge head onto the semiconductor device mounted on the first surface of the first mounting portion while the semiconductor device is in a heated state; and irradiating the droplets on the semiconductor device mounted on the first surface of the first mounting portion using the active light rays; and prior to the discharging of the droplets, performing a surface treatment of the semiconductor device by irradiating the semiconductor device with ultraviolet rays, wherein the performing of the surface treatment includes heating a second mounting portion to a predetermined second temperature before the semiconductor device is mounted on the second mounting portion, mounting the semiconductor device on the second mounting portion, and irradiating the semiconductor device mounted on the second mounting portion with the ultraviolet rays while the semiconductor device is heated.
