Abstract
An land grid array (LGA) or hybrid land grid array (HLGA) includes a socket housing and a plurality of electrical contacts. The socket housing is made of a first material that defines a first dielectric constant. The plurality of electrical contacts extends through the socket housing to electrically couple a printed circuit board on a first side of the socket housing to a processor on a second side of the socket housing. A coating of a second material that defines a second dielectric constant that is higher than the first dielectric constant covers surfaces of a subset of the plurality of electrical contacts.
