Description
301の周辺に配置されている。光モジュール101に光ファイバ103が接続されている。半導体チップ301は、パッケージ基板302上に実装されている。パッケージ基板302は、BGA(Ball Grid Array)ボール303を介してメインボード201上に実
装されている。リッド304を介して半導体チップ301上にヒートシンク305が搭載されている。半導体チップ301から光モジュール101までの伝送路は、半導体チップ301、パッケージ基板302、BGAボール303、メインボード201、インターポーザ102及び光モジュール101の順序となる。
、前記伝熱インターポーザを介して接続されている。
図12〜図15を参照して、比較例について説明する。熱の影響等によって、光モジュール101に故障が発生する場合があるので、光モジュール101のリペアが可能となるように、光モジュール101とパッケージ基板302との接続は、着脱可能なインターポーザやコネクタ等を介して行われることが好ましい。しかし、図12に示すように、光モジュール101をパッケージ基板302上に実装する場合、パッケージ基板302の面積が拡大する。例えば、20mm角のサイズを有する光モジュール101をパッケージ基板302上に実装する場合、パッケージ基板302の面積が400mm2程度拡大することになる。
ル101とパッケージ基板302との接続を行うことが提案されている。図13は、カードエッジコネクタ方式を用いたメインボード201の断面図である。図13に示すように、カードエッジコネクタ方式は、パッケージ基板302上にコネクタ401を実装し、パッケージ基板302に対して水平方向で光モジュール101とコネクタ401とを嵌合する。図14は、スタックコネクタ方式を用いたメインボード201の断面図である。図14に示すように、スタックコネクタ方式は、パッケージ基板302上にコネクタ501を実装し、光モジュール101にコネクタ502を実装し、パッケージ基板302に対して垂直方向でコネクタ501とコネクタ502とを嵌合する。
3は、パッケージ基板2にフリップチップ接合されている。すなわち、半導体チップ3の回路が形成されている表面(以下、回路面という)をパッケージ基板2に向けた状態で、半導体チップ3の回路面に配置された電極と、パッケージ基板2に配置された電極とが、はんだボール等を介して接合されている。
一つに力が加えられる。複数のポゴピン11の少なくとも一つは、光モジュール7から力を受けて縮んだ状態でヒートシンク5及び光モジュール7と接触する。ポゴピン11に対して加わる力(荷重)が小さい場合でも、ポゴピン11が縮むようにすることが好ましい。複数のポゴピン11の少なくとも一つに対して低荷重が加わった場合であっても、複数のポゴピン11の少なくとも一つが縮むことにより、光モジュール7と複数のポゴピン11との接触が維持され、かつ、ヒートシンク5と複数のポゴピン11との接触が維持される。このように、伝熱インターポーザ6を介してヒートシンク5と光モジュール7との熱的接触を維持した状態で、光モジュール7を傾けることが可能である。
数のLGAコンタクト41を介して、光モジュール7からヒートシンク5に熱を伝達してもよい。図9は、メインボード1の断面図である。LGAコンタクト41は、金属等の伝熱性を有する材料で形成されている。LGAコンタクト41は、接触部材の一例である。
材12を用いることにより、保持部材12及び熱伝導部材を介して、光モジュール7からヒートシンク5に熱が伝達され、ヒートシンク5から放熱される。
