A reprint apparatus may include: a defect checking unit configured to check a defective portion in a solder resist layer of a circuit board; a material filling unit positioned above the circuit board to fill the defective portion with a filling material; and a curing unit configured to cure the material filled in the defective portion. The defect checking unit may be configured to calculate a volume of the defective portion, and the material filling unit may be configured to calculate a discharge amount of the filling material based on the calculated volume of the defective portion, and then discharge the filling material by the discharge amount.

Reprint apparatus for circuit board and reprint method using the same

There is provided a bump printing apparatus that can improve the printability of solder bumps printed on a board. The bump printing apparatus may include a printing table onto which a board is mounted; a mask making close contact with the board and printing solder bumps on the board by separating the mask from the board after a printing operation; and mask tables extending from the printing table to edges of the mask and sucking the edges of the mask to bring the edges of the mask into close contact with the board under vacuum.
