  • Publication number: 20220029326
    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.

  • Patent number: 11195789
    Abstract: A bottom side interposer provides a structurally balanced chip carrier module to reduce thermal warp and increase package robustness. The bottom side interposer is attached to the bottom of a chip carrier which carries semiconductor chips on the top side of the chip carrier. The top side of the chip carrier typically includes a top side interposer between the semiconductor chips and the chip carrier. The bottom side interposer has a coefficient of thermal expansion (CTE) that is similar to the chips and top side interposer, or tailored to have a CTE intermediate to the chips and the chip carrier. Pads on the bottom side interposer may be plated or fitted with solder balls to complete the module so the module can be connected to a printed circuit board.
