Abstract

Mounting device (10) for semiconductor packages (11), the device (10) comprising a bottom side (14) comprising one or more cavities (15) to house semiconductor packages (11); a top side (13) comprising a plurality of holes (13a) extending from the bottom side (14) to the top side (13) for accommodating contact pins (12) of the semiconductor package (11); and fixation means to fix the device (10) housing the semiconductor packages (11) to a heat dissipation structure.

Description

technical field [0001] The present invention relates to mounting devices for semiconductor packages. Background technique [0002] Semiconductor packages are commonly used in electronic circuit applications. When conduction cooling is required, a common semiconductor device packaging arrangement includes a substrate that acts as a heat sink and an enclosure that can be placed over the substrate to form an internal cavity above the substrate. Integrated circuits, such as semiconductor chips, and other electronic components may be placed within the cavity and electrically connected to conductive leads / contact pins protruding from the housing. Conductive leads enable electrical connection between the package and a socket, such as a printed circuit board (PCB). Thus, the packaged arrangement allows easy electrical connection between the circuit and external devices, while protecting the semiconductor chip and electrical connections from environmental conditions such as moistur...
