Abstract
A socket for semiconductor package in which most portion of a package side electrode portion of a contact pin has an inclined portion inclined at a predetermined angle with respect to a vertical direction, and when a land grid array package is received in a housing, a contact end of the package side electrode portion abuts on the land electrode within the area of the land electrode, and when the land grid array package is lowered, the contact end slides on the surface of the land electrode to remove foreign matters adhering to the land electrode to thereby put the contact end into contact with the land electrode at a good contact pressure.
Claims10
A socket for semiconductor package comprising:
- a housing for receiving a semiconductor package and packaged on a package board;
- a plurality of contact pins provided in the housing such that they electrically connect a plurality of package electrodes of the semiconductor package to a plurality of board electrodes of the package board, respectively, each of the contact pins having a board side electrode portion that is extended downward from a bottom wall of the housing to be connected to the board electrode and a package side electrode portion that is extended upward from a bottom wall of the housing to be connected to the package electrode;
- and
- a cover provided openably and closably on the housing for pressing the semiconductor package received in the housing, wherein
- most portion of the package side electrode portion is formed into an inclined portion inclined at a predetermined angle with respect to a vertical direction, and a contact end of the package side electrode portion is made to abut on the package electrode within an area of the package electrode when the semiconductor package is received in the housing.
