Desired thermal coupling is achieved by screwing down the heat sink in biasing engagement with the package. An alternate embodiment shows the heat sink which has a snap on flange to attach the heat sink to the adaptor.Field of SearchWith heat sinkWith semiconductor element forming part (e.g., base, of housing) Heat dissipating element held in place by clamping or spring means Pressed against semiconductor element Device held in place by clamping Isolation of cooling means (e.g., heat sink) by an electrically insulating element (e.g., spacer) | |
