One or more devices and/or methods provided herein relate to a method for fabricating a filtering electronic device having a co-integrated impedance modification element and signal transmission line. An electronic structure can comprise a signal transmission line, and an impedance modification element adjacent to and external to the signal transmission line, wherein the impedance modification element comprises a structure having differentiated sections, along the signal transmission line, that provide corresponding differentiated impedances. In an embodiment, the impedance modification element can comprise a plurality of impedance sub-elements spaced apart from one another along and adjacent to the signal transmission line to facilitate the different impedances.

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.

Electrical current flow in a ball grid array (BGA) package can be measured by an apparatus including an integrated circuit (IC) electrically connected to the BGA package. Solder balls connect the BGA package to a printed circuit board (PCB) and are arranged to provide a contiguous channel for a current sense wire. A subset of solder balls is electrically connected to supply current from the PCB through the BGA package to the IC. The current sense wire is attached to the upper surface of the PCB, within the contiguous channel, and surrounds the subset of solder balls. An amplifier is electrically connected to the current sense wire ends to amplify a voltage induced on the current sense wire by current flow into the BGA package. A sensing analog-to-digital converter (ADC) is electrically connected to convert a voltage at the output of the amplifier into digital output signals.

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.

A set of features for a product is identified. It is determined that preventing an electrical connection at a ball-grid-array location on a ball-grid-array assembly of the product would result in the set of features.

With that application of suction, a solder ball at the target BGA location is drawn into the via.
