Description
このとき、前記気体成分が、誘電体を含むまだ脱脂されていないグリーンシートを積層方向と直角方向の成分を有する圧力で押すこととなる。そして、グリーンシートを積層方向に剥離することとなり、グリーシート間に隙間を生じさせて、その後の焼結を困難にする課題があり、クラック及びデラミネーションなどの欠陥の発生を抑制し歩留まりの向上した積層セラミックス電子部品及び膜電子部品を製造することが望まれる。
以下に示す誘電体スラリー、内部電極用ペーストを調製した。
20:内部電極層の印刷層
Claims (2)
- 内部電極層を有する電子部品を製造する方法であって、
導電体粉末と共材を含有する粉末成分と、溶媒などの揮発性有機成分と、バインダーや可塑剤などの不揮発性有機成分と、を含有する内部電極用ペーストを誘電体層となるグリーンシートに印刷部および非印刷部を有する印刷パターンにより印刷する工程と、
前記グリーンシートを積層して脱バインダー処理を行うことで揮発性溶剤を揮発させ、焼成して、前記内部電極層を形成することになる焼成前電極膜を形成する工程と、を有し、
前記内部電極用ペーストの印刷面上には、前記非印刷部が前記印刷面の中心から放射状に形成され、脱脂前の成型体表面まで繋がっており、前記印刷部のいずれの場所からでも前記非印刷部までの印刷面上の距離が2mm以下であり、前記非印刷部は印刷後にシート厚の1/30以上の厚さ分薄く形成された電極となることを特徴とする内部電極を有する電子部品の製造方法。 - 内部電極層を有する電子部品を製造する方法であって、
