底部が塞がった円筒状のポリフタルアミド(PPA)樹脂製枠材5(内径2.0mm、深さ1.0mm)の内底部の中心部に向かって、リードフレーム2、3が側壁から延出しており、リードフレーム2の中央部上にLEDチップ1が載置されており、LEDチップ1とリードフレーム3はボンディングワイヤ4により電気的に接続している未封止の発光ダイオード内に脱泡した硬化性シリコーン組成物をディスペンサーにより注入した。その後、加熱オーブン中で、100℃で30分、続いて150℃で1時間加熱することにより硬化性シリコーン組成物を硬化させ、図1に示す発光ダイオードを作製した。
上記の方法で作製した8個の発光ダイオードについて、リードフレーム2、3、およびボンディングワイヤ4と硬化物6間での剥離状態を光学顕微鏡で観察し、剥離が見られた発光ダイオードの個数の割合を表2に示した。
上記の方法で作製した8個の発光ダイオードを、85℃、85%の恒温恒湿室に24時間入れた後、280℃のオーブン内に30秒間置き、その後、室温(25℃)下に戻して、リードフレーム2、3、およびボンディングワイヤ4と硬化物6間での剥離状態を光学顕微鏡で観察し、剥離が見られた発光ダイオードの個数の割合を表2に示した。
上記の方法で作製した8個の発光ダイオードを、85℃、85%の恒温恒湿室に72時間入れた後、280℃のオーブン内に30秒間置き、その後、室温(25℃)下に戻して、リードフレーム2、3、およびボンディングワイヤ4と硬化物6間での剥離状態を光学顕微鏡で観察し、剥離が見られた発光ダイオードの個数の割合を表2に示した。
