Abstract

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. The ball-grid-array location is established as a target BGA location based on that determination. Suction is applied to a via at the target BGA location during reflow of the ball-grid-array assembly. With that application of suction, a solder ball at the target BGA location is drawn into the via.
