Screen printing apparatus, electronic component mounting system and screen printing method

摘要

A screen printing apparatus includes a substrate positioning part that upwardly and downwardly moves a substrate with the substrate clamped by a clamp member to thereby bring the substrate into contact with a mask stretched in a frame body and fixed in a predetermined height position from an underside of the mask and position the substrate in a predetermined height position, a mask suction part that is provided in the clamp member and sucks the mask in contact with the substrate, and a screen printing part that prints paste on the substrate through a pattern hole formed in the mask by sliding a squeegee on the mask to which the paste is supplied. The mask is pressed up by a predetermined amount through the substrate with the mask sucked by the mask suction part when the substrate is upwardly moved by the substrate positioning part.

主权项

1. A screen printing apparatus comprising:
a mask stretched in a frame body fixed at a predetermined height position and having at least one pattern hole formed therein; a substrate holder that clamps and holds a substrate at sides of the substrate by a pair of clamping members below the mask; a substrate positioning part that upwardly and downwardly moves the substrate clamped by the clamping members to thereby bring the substrate into contact with the mask from an underside of the mask and position the substrate in a predetermined height position; a mask suction part that is provided in each of the clamping members and sucks the mask in contact with the substrate; a screen printing part that prints paste on the substrate through the at least one pattern hole formed in the mask by sliding a squeegee on the mask to which the paste is supplied; and a control unit for controlling the substrate positioning part and each mask suction part such that the mask is pressed up by a predetermined amount through contact with the substrate when the substrate is upwardly moved by the substrate positioning part and the mask is sucked by each mask suction part provided in each clamp member.
