Description
図5および図6を参照して、先ず、発光モジュール10の材料となる基板40を用意して、導電パターンを形成し、絶縁層42を部分的に除去する。図5は単層の配線層(導電パターン)が形成される場合を示し、図6は多層の配線層が形成される場合を示している。
図7を参照して、次に、絶縁層42に被覆されていない領域の基板40の上面から凹部18を形成する。凹部18の形成は、選択的なエッチング、ドリル加工、プレス加工等により可能であるが、以下ではプレス加工による凹部18の形成方法を説明する。
図8(A)および図8(B)を参照して、次に、各ユニット46同士の間に、分離用の溝を設ける。図8(A)を参照すると、基板40の各ユニット46同士の間には、上面から第1溝54が形成され、下面からは第2溝56が形成されている。両溝の断面は、V型の形状を呈する。
本工程では、凹部18の内壁を、メッキ膜から成る被覆層34により被覆する。
図10の各図を参照して、次に、各ユニット46の凹部18に発光素子20(LEDチップ)を実装して、電気的に接続する。図10(B)を参照して、発光素子20の下面は、接合材26を介して凹部18の底面28に実装される。発光素子20は下面に電極を有さないので、接合材26としては、樹脂から成る絶縁性接着剤または導電性接着材の両方が採用可能である。また、導電性接着材としては、半田または導電性ペーストの両方が採用可能である。更に、凹部18の底面28は、半田の濡れ性に優れる銀等のメッキ膜から成るので、絶縁性材料よりも熱伝導性に優れた半田を接合材26として採用できる。
図11の各図を参照して、次に、基板40に設けた各ユニット46の凹部に封止樹脂32を充填させて、発光素子20を封止する。封止樹脂32は、蛍光体が混入されたシリコン樹脂からなり、液状または半固形状の状態で封止樹脂32を凹部18および開口部48に充填されて固化される。このことにより、発光素子20の側面および上面と、発光素子20と金属細線16との接続部が、封止樹脂32により被覆される。
図12の各図を参照して、次に、第1溝54および第2溝56が形成された箇所で、基板40を各ユニットに分離する。
