Reinforcement structures for surface mount packaging components
In accordance with at least one aspect of this disclosure, a system includes a reinforcement structure configured to seat in an air gap between one or more solder balls of a ball grid array of a surface mount packaging component. The reinforcement structure is configured and reduce bending of the circuit board during acceleration of the circuit board.
1. A system, comprising,
a reinforcement structure configured to seat in an air gap between one or more solder balls of a ball grid array of a surface mount packaging component, the reinforcement structure configured to reduce bending of a circuit board during acceleration of the circuit board, further comprising one or more support beams configured to seat in the air gap between the one or more solder balls to provide an airflow path through and under the ball grid array during reflow.
2. The system of claim 1 , wherein the reinforcement structure does not surround each solder ball of the ball grid array individually.
3. The system of claim 1 , wherein the reinforcement structure is formed from one or more of metal, plastic, ceramic, and/or silicon.
4. The system of claim 1 , wherein a height of the reinforcement structure is configured to limit an amount of collapse of the solder balls during reflow.
5. The system of claim 1 , further comprising,
an electronics component configured to attach to a first side of the circuit board via the surface mount packaging component; and
the ball grid array operatively connected to a second side of the surface mount packaging component configured to mount the packaging component to the circuit board,
wherein the electronics component is communication with the reinforcement structure through one or more vias in the surface mount packaging component.
6. The system of claim 5 , wherein the one or more vias include thermal vias, wherein the one or more thermal vias are configured to conduct thermal energy from the electronics component to the second side of the surface mount packaging component and through the reinforcement structure to dissipate the thermal energy through the circuit board.
7. The system of claim 5 , wherein the reinforcement structure is adhered to the second side of the surface mount packaging component.
8. The system of claim 5 , further comprising a potting material filled within the ball grid array and openings of the reinforcement structure are configured to provide additional structural support and/or shock absorption and/or stress dispersion to the circuit board and the electronics component during acceleration of the circuit board.
9. The system of claim 5 , wherein the system is included in a moving platform subject to acceleration.
