Method and apparatus for drawing a thick film circuit
摘要:
A method and apparatus for drawing a thick film circuit on a substrate (2) by discharging a paste from a paste discharge hole provided at one end of a drawing nozzle (1), the drawing nozzle (1) being located close to the substrate (2) and relatively moved with respect to the substrate (2). The discharge rate of the paste is controlled in accordance with the relatively moving speed between the drawing nozzle (1) and the substrate (2), thereby preventing variations of film thickness and line width caused by variations in the moving speed and making it possible to form a thick film circuit at a high speed and with high accuracy.
