Abstract:
1. A substrate holder for holding a circuit board onto which a viscous material for bonding electronic components is printed by means of a squeegee through a screen mask, the substrate holder comprising: a plate-like main body having a base surface; a first holding area provided on the base surface to hold the screen mask; a second holding area provided on the base surface to hold the circuit board; wherein at least one of the first holding area and the second holding area is arranged to support the squeegee via the screen mask placed on the circuit board such that the squeegee is abutted against the circuit board while the circuit board is held to the second holding area; wherein the first holding area includes two first adhesive holding regions having a first tackiness, the first adhesive holding regions being arranged to extend in a first direction and parallel with each other; wherein the second holding area includes at least two second adhesive holding regions having a second tackiness which is different from the first tackiness, the second adhesive holding regions being arranged along the first direction and between the two first adhesive holding regions so as to be spaced apart from each other at a predetermined distance; and wherein the first direction is a direction in which the squeegee is to be moved to print the viscous material.
