Semiconductor device having a module board
View Patent ↗A mother board mounts a memory module via a plug-socket coupling, wherein the edge of the memory module has a plug member mounted on a socket member of the mother board. The mother board has a plurality of abutment members abutting the edge surface of the bottom edge of the memory module for which the plug is formed. The abutment members act as ground terminals for connecting the ground layer of the memory module to the ground layer of the mother board, and also act as heat radiation members.
1. A semiconductor device comprising:
a module board having a plurality of pad terminals on both surfaces of a first edge thereof, said pad terminals configuring a plug member; and
a mother board having a plurality of contact terminals arranged in two rows, said contact terminals configuring a socket member for connecting to said plug member by sandwiching said first edge between said two rows of said contact terminals,
wherein said mother board has an abutment member disposed between said two rows of said contact terminals for abutting an edge surface of said first edge,
wherein said abutment member is made of a conductive material,
wherein said edge surface exposes therethrough an edge of a ground layer of said module board, and said abutment member is connected to a ground layer of said mother board.
