Description
図1に、本発明の実施例の印刷装置10を示す。印刷装置10は、回路基板12に回路パターンを印刷するための装置である。印刷装置10は、搬送装置20と吐出ヘッド22と照射装置24と吐出ヘッド移動装置(以下、「移動装置」と略す場合がある)26とを備えている。
上述した構成により、印刷装置10では、回路基板12の上面に、銀ナノ粒子ペーストが吐出されることで、銀ナノ粒子ペーストの塗膜が形成される。そして、その銀ナノ粒子ペーストの塗膜が加熱されることで、銀ナノ粒子が融着し、回路パターンが回路基板12上に印刷される。具体的には、まず、印刷装置10の作動を制御する制御装置(図示省略)の指令により、回路基板12が作業位置まで搬送され、その位置において、回路基板12が、基板保持装置32によって固定的に保持される。
上記実施例では、塗膜70内に沈降した電磁波吸収材72に電磁波が照射されることで、塗膜70が下方から加熱されているが、塗膜を下方から加熱可能な位置であれば、電磁波吸収材を様々な箇所に配置させることが可能である。具体的には、塗膜と回路基板との間に電磁波吸収材を配置し、その電磁波吸収材により塗膜を加熱する印刷装置を、変形例1の印刷装置80として、図3に示す。なお、印刷装置80は、銀ナノ粒子ペーストの塗膜および電磁波吸収材を除いて、印刷装置10と同様の構成であるため、印刷装置10と同様の機能の構成要素については、同じ符号を用いて説明を省略あるいは簡略に行う。
上記実施例および変形例とは異なり、電磁波吸収材を回路基板内に配置させ、その電磁波吸収材により銀ナノ粒子ペーストの塗膜を加熱してもよい。具体的には、電磁波吸収材を含む回路基板上に銀ナノ粒子ペーストの塗膜を形成し、その電磁波吸収材により塗膜を加熱する印刷装置を、変形例2の印刷装置90として、図4に示す。なお、印刷装置90は、回路基板を除いて、印刷装置10と同様の構成であるため、印刷装置10と同様の機能の構成要素については、同じ符号を用いて説明を省略あるいは簡略に行う。
上記実施例および変形例とは異なり、回路基板を保持する基板保持装置内に電磁波吸収材を配置させ、その電磁波吸収材により銀ナノ粒子ペーストの塗膜を加熱してもよい。具体的には、電磁波吸収材を含む基板保持装置によって回路基板を保持し、その回路基板上に形成された銀ナノ粒子ペーストの塗膜を、基板保持装置に含まれる電磁波吸収材により加熱する印刷装置を、変形例3の印刷装置100として、図5に示す。なお、印刷装置100は、基板保持装置を除いて、印刷装置10と同様の構成であるため、印刷装置10と同様の機能の構成要素については、同じ符号を用いて説明を省略あるいは簡略に行う。
