A system and method for slowing a vehicle. Road conditions around the vehicle are monitored, and determined if those road conditions are hazardous. An engine control unit is informed of the hazardous road conditions and alters the operation of the engine control unit in response to the hazardous road conditions. When an operator of the vehicle desires to slow the vehicle down, an indication is received indicating the intent to slow the vehicle down. The vehicle is then slowed based upon the altered operation of the engine control unit by applying a vacuum to increase a manifold vacuum of the engine.

A ball-grid-array component of a ball-grid array assembly is analyzed prior to reflow. A predicted warping pattern of the ball-grid-array component that is likely to occur during reflow is predicted based on the analyzing. A solder ball ball-grid-array defect that could be caused by the predicted warping pattern is predicted. An initial via suction pattern to mitigate the ball-grid-array defect is assigned. A vacuum head is applied to a via in the ball-grid-array assembly. The solder ball is located at the opposite end of the via from the vacuum head. Suction is applied to the via based on the via suction pattern. The suction draws a portion of the solder ball into the via during reflow.
