Attaching a Component to a Circuit Board Using an Over-filled Cavity of Solder
In general, the subject matter described in this disclosure can be embodied in a circuit-board attachment method. The method includes providing a circuit board that defines a channel in a surface of the circuit board, and placing a stencil over the surface of the circuit board so that a slot that is in the stencil and defined by the stencil aligns with the channel in the circuit board. The method includes applying solder to the stencil when the slot in the stencil is aligned with the channel in the circuit board to provide the solder into the slot in the stencil and the channel, and removing the stencil, leaving the solder in the channel and protruding from the channel. The method includes placing a component in contact with the solder that is protruding from the channel, and heating the solder to attach the component to the circuit board.

SYSTEMS AND METHODS FOR PROVIDING ELECTROMAGNETIC INTERFERENCE (EMI) COMPARTMENT SHIELDING FOR COMPONENTS DISPOSED INSIDE OF SYSTEM ELECTRONIC PACKAGES
A compartment EMI shield for use inside of a system module package is provided that comprises at least a first set of electrically-conductive wires that surrounds and extends over circuitry of the module package. Adjacent wires of the first set are spaced apart from one another by a predetermined distance selected to ensure that the compartment EMI shield attenuates a frequency or frequency range of interest. First and second ends of each of the wires are connected to an electrical ground structure. A length of each wire that is located in between the first and second ends of the respective wire extends above the circuitry and is spaced apart from the components of the circuitry so as not to be in contact with the components of the circuitry.
Using a thermoelectric component to improve memory sub-system performance
A system receives event information associated with an event that corresponds to a temperature of a memory sub-system including memory devices encased in respective packages. The system determines whether the event information associated with the event satisfies a threshold condition. Responsive to determining that the event information associated with the event satisfies the threshold condition, the system causes a thermoelectric component (TEC) that is coupled to an external surface of each of the respective packages of the memory devices of the memory sub-system to transfer thermal energy between the TEC and the memory devices via thermal conduction.
