## Abstract

The present invention is directed to a device for securing an electrical component to a pin grid array (PGA) socket that has a substantially planar body portion and a plurality of conductor pins, which are electrically connectable to a circuit board and project outwardly in a direction substantially perpendicular to the planar body portion. The device comprises a base member that has a plurality of conductor pin apertures which extend through the base member. Each of the conductor pin apertures are registered to receive therethrough a corresponding one of the plurality of conductor pins, to thereby sandwich the base member between and anchor the base member to the circuit board and the PGA socket when the PGA socket is electrically connected to the circuit board. The device further comprises a means for releasably securing the electrical component to the PGA socket. The means is coupled to the base member and a surface of the electrical component and transmits a retaining force from the base member to the electrical component, thereby substantially preventing the electrical component from separating from the PGA socket.

## Claims

### Claim 1

A method for securing electrical components to a circuit board having a plurality of securing openings therethrough, the method steps comprising:
placing a base member on said circuit board in a manner to register a plurality of conductor pin apertures formed through said base member with said plurality of securing openings;
registering and inserting a plurality of conductor pins projecting outwardly from a pin grid array (PGA) socket through said plurality of conductor pin apertures and said plurality of securing openings and sandwiching said base member between and anchoring said base member to said circuit board and said PGA socket; and
soldering said PGA socket to said circuit board.

### Claim 2 (depends on 1)

The method of claim 1 further comprising the step of securing an electrical component to said PGA socket by a releasable securing means, said means coupling said base member to a surface of said electrical component and transmitting a retaining force from said base member to said electrical component, thereby substantially preventing said electrical component from separating from said PGA socket.

### Claim 3 (depends on 2)

The method of claim 2 wherein said wherein said base member has a generally planar portion and said releasable securing means is comprised of an elongated, resilient clamping projection integrally formed with and extending from said base member in a direction substantially perpendicular to said planar portion and a distance sufficient to engage a top surface of said electrical component and securely hold said electrical component to said PGA socket.

### Claim 4 (depends on 2)

The device of claim 2 wherein said base member has a generally planar portion and said releasable securing means is comprised of a plurality of spaced apart, elongated, resilient clamping projections integrally formed with and extending from said base member in a direction substantially perpendicular to said planar portion and a distance sufficient to engage a top surface of said electrical component, to thereby securely hold said electrical component to said PGA socket.

### Claim 5 (depends on 2)

The device of claim 2 wherein said base member is comprised of molded plastic material and has a generally planar rectangular shape portion and said releasable securing means is comprised of two opposite diagonally disposed elongated, resilient clamping projections integrally formed with and extending from said base member in a direction substantially perpendicular to said planar rectangular portion, said clamping projections extending a distance sufficient to engage a top surface of said electrical component, to thereby securely hold said electrical component to said PGA socket.

### Claim 6 (depends on 2)

The device of claim 2 wherein said base has a generally planar rectangular shape and a perimeter side surface thereabout and said releasable securing means is comprised of clamping tab members disposed on opposite sides of said base member and extending outwardly from said base member in a direction perpendicular to said side surface and an elongated spring-like clip member having opposing inwardly curved end portions depending therefrom, said curved end portions having a length sufficient to extend from said electronic component to said tab members and engage a bottom surface of said tab members, to thereby securely hold said electrical component to said PGA socket.

### Claim 7 (depends on 2)

The method of claim 2 wherein said electrical component is a central processing unit.
