Abstract
【解決手段】 本発明の配線基板への電子部品の取付構造は、ランド部3aを有する配線パターン3が設けられた配線基板2と、ランド部3aに半田付けされる複数の電極1bを有する電子部品1とを備え、ランド部3aは半田付可能な第1の金属材で形成されると共に、ランド部3aに隣接する配線パターン3には、半田付不可能な第2の金属材が設けられたため、第2の金属材によってランド部3aからの半田の流出を防止でき、従来の半田レジスト膜が不要となって、生産性が良好であると共に、電子部品1と配線基板2の表面との間で接着剤6による接着ができて、電子部品1の取付の強硬なものが得られる。

Description
また、第3の解決手段として、前記第1の金属材は、銅、又は錫、或いはそれらを主成分とする合金で形成された構成とした。
また、第5の解決手段として、前記配線パターンと前記ランド部が前記第1の金属材で形成されると共に、前記第2の金属材が前記ランド部の隣接する位置の前記配線パターンを覆った構成とした。
その結果、配線パターン2の表面は、大部分が露出した状態となっている。
この時、接着剤6は、配線基板2の表面に直接、接着されて、接着剤6の接着が強固になる。
