Description
水晶発振器は周波数の基準源として通信機器等に広く用いられる。このようなものの一つに、水晶振動子を恒温槽に収容して動作温度を一定として、発振周波数を高安定に維持した基地局や中継局の通信機器に内蔵される恒温型の水晶発振器(以下、恒温型発振器とする)がある。
第2図及び第3図は一従来例を説明する図で、第2図(a)は恒温型発振器の断面図、同図(b)は恒温槽9の配置断面図であり、第3図(a)は第1基板1aの一部拡大平面図、同図(b)は金属ピン4を立設した第1基板1aの一部拡大図、同図(c)は同側面図である。
しかしながら、上記構成の恒温型発振器では、第2基板1bを支持する金属ピン4の下端側先端は第1基板1aの穴5に挿入され、第1基板1aの電極ランド6と半田7によって接合される。このため、半田接合時の熱や、恒温型発振器が図示しないセット基板に半田リフローによって搭載されるときの熱によって、第1基板1aの穴5内の閉じ込められた空気が膨張し、半田7が破裂する。これにより、第1基板1aに対して金属ピン4を植設できなかったり、接合強度が低下する問題があった。
本発明は、第1基板に対する金属ピンの接合を確実にした二段構造の実装基板及びこれを用いた水晶発振器を提供することを目的とする。
本発明の請求項2では、請求項1において、前記第2基板は前記金属ピンの上端側に設けられて円板状に突出したストッパーに位置決めされる。これにより、第2基板を金属ピンに確実に位置決して水平に維持する。
上記実施例では、第1及び第2基板1bはガラスエポキシ材としたが、セラミック等であっても同様に適用できる。また、水晶振動子10は恒温槽9に収容した恒温型発振器として説明したが、恒温槽9に収容しない場合でも、同様に適用できる。また、第1基板1aは積層基板としたが、単板でもよいことは勿論である。
Claims (3)
- 外底面に実装端子を有する第1基板上に金属ピンによって第2基板を支持し、前記金属ピンの先端が前記第1基板の表面に設けられた有底の穴に挿入され、前記有底の穴の外周となる前記第1基板の表面に設けられた環状の電極ランドに半田によって固着された二段構造の実装基板において、前記有底の穴の内部に前記第1基板の素地が露出した無電極部を形成するとともに、前記環状の電極ランドの一部を半径方向に開放する切欠部を設けて前記有底の穴の外周にも無電極部を形成し、塗布された前記半田と前記無電極部の間に前記有底の穴と空間的に接続する連通部を形成したことを特徴とする二段構造の実装基板。
- 請求項1において、前記第2基板が、前記金属ピンの上端側に設けられた円板状に突出したストッパーにより位置決めされる二段構造の実装基板。
- 請求項1において、前記第2基板の下面に恒温槽に収容された水晶振動子が配設され、かつ、前記第2基板の上面に回路素子が配設された水晶発振器。
