Title: Thick film printing method and ceramic substrate suction apparatus
Inventor: KUBO HITOSHI
IPC: B41F15/26
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a thick film printing method capable of forming a pattern on a ceramic substrate having a through-hole with high accuracy and a suction apparatus capable of being used therein. SOLUTION: Since a changeover valve is changed over to a release position prior to printing in a printing process, the suction from an opening 44 is not performed during printing and the opening 44 is released to atmospheric pressure. However, since the suction from a suction hole 50 is succeedingly performed even during printing because an exhaust pump is succeedingly operated from a suction process, the ceramic substrate 11 is sucked to a suction surface 36 by the suction from the suction hole 50 to be held to a fixed state. Since a slight gap can be present between the substrate 11 and the suction surface 36 even in this sucked and fixed state, an air stream can be generated from the surface 12 of the substrate to the suction hole 50 through the through- hole but, since the opening 44 is released to atmospheric pressure, the air stream is relaxed or substantially eliminated.
