  • Publication number: 20240097292
    Abstract: A voltage source watchdog comprising a passive device is placed in series between a voltage source and a load. The passive device includes an electromigration (EM) joint of known materials that will create an electromigration void after a specified amount of current passes through the EM joint. After a known amount of current as passed through, a void is created and a voltage will no longer be sensed, thus providing a sure safety mode situation. When the voltage source is a battery, the battery life may be extended by selectively enabling voltage measurement operations for the proposed watchdog.

  • Publication number: 20240008208
    Abstract: Disclosed herein is a method for producing a land grid array (LGA) socket connector assembly and the resultant assembly. The method comprises providing a carrier having a first carrier thickness with an array of vias, each having a first diameter, providing pockets around top surfaces of the vias, each having a second diameter and creating a portion of the pockets having a second carrier thickness that is less than the first carrier thickness, providing socket contact springs, each comprising a hole support structure that supports the socket contact spring within the via, and a contact beam configured to contact a conductor of an integrated circuit to be placed within the socket connector assembly, wherein a portion of carrier having a first carrier thickness is configured to prevent the contact beam from inelastically deforming when bent under load. Alternately, a contact feature may be used to prevent the inelastic deformation.

  • Patent number: 11664302
    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.
