Printed circuit board retention bands

1. A socket locking system comprising:

a socket;

a printed circuit board (PCB) card disposed in the socket;

a first locking handle and a second locking handle to lock the PCB card in the socket; and

a PCB retention band including:

an elongated closed loop forming a first distal end and a second distal end opposite from the first distal end, wherein the first distal end is to contact the first locking handle and the second distal end is to contact the second locking handle; and

a retention portion coupled to the elongated closed loop of material to contact a top surface of the PCB card to apply a force along at least a vertical axis of the PCB card in the socket, wherein the retention portion has a width that is greater than a width of the PCB card, wherein the retention portion is to contact each of a first face, a second face, and the top surface of the PCB card when the PCB retention band is in contact with the first locking handle and the second locking handle.

2. The system of claim 1 , wherein the PCB card is a dual in-line memory module (DIMM) card.

3. The system of claim 2 , wherein the system is free of locking handle adapters.

4. The system of claim 3 , elongated closed loop directly contacts each of the first locking handle and the second locking handle.

5. A printed circuit board (PCB) retention band comprising:

an elongated closed loop forming:

a first distal end to contact a first locking handle of a socket included in a PCB; and

a second distal end to contact a second locking handle of the socket;

a retention portion disposed between the first distal end and the second distal end to contact a top surface of PCB card to apply a force along at least a vertical axis of the PCB card to retain the PCB card in the socket, wherein the retention portion includes a groove having a volume sized to receive a portion of the top surface of the PCB card in the volume of the groove.

6. The PCB retention band of claim 5 , wherein the elongated closed loop defines a first opening and a second opening, and wherein the retention portion is disposed between the first opening and the second opening.

7. The PCB retention band of claim 5 , wherein a length of the retention portion is less than a length of the elongated closed loop.

8. The PCB retention band of claim 5 , wherein the retention portion is integral with the elongated closed loop.

9. The PCB retention band of claim 8 , wherein the elongated closed loop is formed of a flexible material, wherein in the flexible material includes rubber, silicone rubber, or combinations thereof.

10. A network device comprising:

a printed circuit board (PCB) including a socket;

a PCB card disposed at least partially in the socket;

a first locking handle and a second locking handle to lock the PCB card in the socket; and

a PCB retention band formed by an elongated closed loop and a retention portion, the elongated closed loop having a first distal end in contact with the first locking handle and a second distal end in contact with the second locking handle, and the retention portion in contact with a top surface of the PCB card to disposition the PCB card in the socket by imparting a force on the PCB card at least along a vertical axis.

11. The network device of claim 10 , wherein the retention portion in contact with the top surface of the PCB card imparts a force on the PCB card at least along the vertical axis that is substantially perpendicular to a top surface of the PCB.

12. The network device of claim 10 , wherein the network device is a wireless local area network (WLAN) controller.
