Method for tab features to reduce contact damage during LGA
socket alignment and assembly
Disclosed is a method for tab
features to reduce contact damage during land-grid array (LGA) socket alignment
and assembly. Benefits include improved
functionality and improved performance.
With an LGA socket, the contact has sharp angles so it can
reduce the contact resistance between the contact and the substrate pads.
However, sharp angles are easily damaged during assembly and handling. Contact
damage is one of the main issues during the socket LGA development.
Conventionally, an additional plastic cover is added to the
socket to reduce contact damage due to handing. A cover does not address the
damage that can occur during package assembly because the cover must be removed
during assembly (see Figure 1).
The disclosed method includes tab features to reduce contact
damage during LGA socket alignment and assembly.
The added tab feature is very simple to produce on the socket.
When the package is being aligned to the socket, the tab prevents the package
from contacting the socket contacts to avoid damage to the socket contacts.
When the package is pushed to the socket by the activation mechanism, the tab
breaks off allowing the package to engage with the socket.
The disclosed method
provides advantages, including:
• Improved functionality due to preventing the package from conta...
