Description
図7(b)は図7(a)に示したLED基板130を用いて表面実装型の電子部品としてのLEDを形成する方法を示す図である。図7(b)に示すように、LED基板(図7(a)の130)の上面(ここでは銅箔パターン133)の上にLED素子101を固定するとともに、LED素子101と表面メッキ部135a、134aとをそれぞれワイヤー106で電気的に接続する。137は透明なモールド樹脂よりなる封止部材であり、図6(b)の封止部材127と同様にして形成される。この形成の際、銅箔パターン133により、スルーホール138、138の入り口が塞がれているので、溶融した封止部材137のモールド樹脂がスルーホール138を通って絶縁基板232の裏面にしみ出すことが防止される。このようにして図7(b)に示すLEDの集合体170Sが形成された後に点線で示すライン(スルーホール138を通るライン)に沿ってダイシングされ、図7(c)に示す個々のLED170に分割される。このとき、LED170においては銅箔パターン133は分割されて、表面メッキ部135aに導通する左側の導箔電極133aと、表面メッキ部135bに導通する右側の導箔電極133aとに分かれる。
前記導通電極手段は銅等を下地とするものであり、導通電極手段上を全面にわたり、プリプレグ等の樹脂材で被覆した後、そのプリプレグ等の樹脂材の一部を除去し、除去により露出した銅等の下地の上に前記LED素子を実装するためのメッキ処理を施したことを特徴とする。
また、上記の課題を解決するための第6の手段として本発明は、LED基板上にLED素子を搭載しモールド樹脂よりなる封止部材により封止して形成されるLED(発光ダイオード)のLED基板の構造において、該LED基板は絶縁基板にLED素子を外部に導通するための導通電極手段とスルーホールを設け、かつ前記導通電極手段は前記絶縁基板上面において前記絶縁基板の一端のコーナーを除いて前記絶縁基板がはみ出るように配置され、前記スルーホールは前記絶縁基板の一端のコーナーに配置されており、銅箔よりなる導通電極手段によりスルーホールの入り口を塞ぎ、前記銅箔上の窓状の一部を除いてプリプレグにより前記絶縁基板上の全面を被覆し、前記銅箔上の窓状の一部であって前記プリプレグにより被覆されない部分に、前記LED素子をダイボンド及びワイヤーによりボンディングするための実装領域を設けてなる構造を有することを特徴とする。
なお、下地パターン電極4として銅をある程度厚くメッキしておけば、図2(d)に示すように被覆樹脂6の必要部分(表面メッキ部5a、5bに対応する部分)を除去する際に、エッチング液によって下地パターン電極4が侵され、破損することを防ぐことができる。
なお、本実施例1においては、表面メッキ部(5a、5b)を、ワイヤーによるボンディングをするためのボンディングエリアとしたが、本発明はこれに限らず、かかる表面メッキ部をダイボンド及びワイヤー等の手段によりLED素子をボンディングするための実装領域とすることができる。
ため、ダイシングのストレスによっても、絶縁基板2から剥離することはない。この点が図7に示した従来例と異なるところであり、本実施例2の長所である。
