Multiple Contact Power Bar for Electronic Socket

Disclosed is a method that uses a power bar to connect to multiple contacts within an electrical socket to equalize current and heating.

Background

Typical power delivery produces unequal current and heating traveling in and out of the socket (see Figure 1).

General Description

The disclosed method is a contact power bar, normally embedded in an electronic processor socket, that makes contact with pins from a processor and surface mounts on a processor board (see Figure 2 and 3). The beams contact a pin on a processor/circuit to transfer electricity from the processor/circuit to and from the circuit board. The multiple contact power bar equalizes the power over multiple contacts to prevent unequal load to individual pads on the die, or on a interposer in between the socket and the die.�

The following steps are used to create the disclosed method:

 

  1. Mold the base and cover.
  2. Mold or fabricate the lever.
  3. Form and plate the contacts.
  4. Insert power bars.
  5. Insert the contacts into the base and power bars.
  6. Attach the cover.
  7. Attach the actuation mechanism to the socket.
  8. Put solder paste on the solder pad.

9.      Attach solder material to circuit board pad in reflow oven.

Advantages

The contact power bar equalizes both current and heating; power and ground bars can be set side by side to reduce inductance. Additionally, the power bar can be used to rebalance the socket for better surface mounting.
