Patent ID: 8647560

Claim:
A method for forming a pattern on a board, comprising: a step of providing a base material for forming the board; a step of forming a first area and a first liquid-receiving area communicated with the first area, on one surface of the base material, the first area having lower liquid repellence than that of areas other than the first area on the one surface of the base material; a step of laser processing in which a laser irradiates the first area on the one surface of the base material to form a first groove defined by an exposed surface, and to lower liquid repellence in an entire region of the exposed surface defining the first groove compared to liquid repellence of the areas other than the first area on the one surface of the base material; a step of arranging a liquid droplet jetting unit above the one surface of the base material; a liquid charging step of charging, via surface tension, a plurality of liquid droplets into the first area communicated with the first liquid-receiving area by landing the liquid droplets jetted from the liquid droplet jetting unit on the first liquid-receiving area; and a solidifying step of solidifying the liquid charged into the first area, wherein the first area has a width which is smaller than the diameter of the liquid droplets before landing on the first liquid-receiving area.
