Method for a recessed alignment feature

Disclosed is a method for a recessed alignment feature. Benefits include improved ease of handling and improved component stackability.

Background

              Conventional CPU sockets have alignment posts that do not recess into the cover (see Figure 1). Heat sinks and other components are designed so that they do not interfere with the posts. This approach adds to the cost of the unit.

Description

              The disclosed method is an alignment post that is part of the plastic cover (see Figure 2). The alignment post is raised above the cover when the socket is in Open position. The post is recessed in the cover when the socket is in Closed position. This design enables the socket cover to be flat in the Closed position and eliminates and any stack up issues with other components.

              Steps for making the method include:

1.      Mold the plastic cap as part of the top cover.

2.      Route the plastic cap.

3.      Assemble the socket.

4.      After the socket has been placed on the boards, remove the plastic cap by applying force near the score marks.

 Advantages

              The recessed post helps locate the post at the ideal position and eliminates any stack up issues. The plastic cover has enough material to allow the alignment post to recess. The alignment post can be recessed and raised by the same CAM used to actuate the socket or a separate CAM.
