Abstract
A thick film drawing apparatus includes a substrate holding member (50) for holding a substrate (a), moving coils (60) for holding the substrate holding member (50), a drawing head (20) having a nozzle (30) and a stylus (33) for emitting pastes for drawing on a surface of the substrate (a) moving thereon and pushing the substrate (a) downward, respectively, wherein in the drawing process the drawing head (20) is locked of up/down motions and the substrate holding member (50) is raised/lowered at substantially constant weaker force by the moving coils (60), and thereby a relative-moving response of the up/down directions of the nozzle (30) is improved and a contact force of the stylus (33) on the substrate (a) is kept under a predetermined constant value, therefore a thickness of thick film line (c) is kept uniform and circuit patterns are prevented from being flawed.
