Abstract
A structure with controlled capillary coverage is provided and includes a substrate including one or more first contacts, a component and adhesive. The component includes one or more second contacts and a rib disposed at a distance from each of the one or more second contacts. The component is disposed such that the one or more second contacts are communicative with the one or more first contacts and corresponding surfaces of the substrate and the rib face each other at a controlled gap height to define a fill-space. The adhesive is dispensed at a discrete point whereby the adhesive is drawn to fill the fill-space by capillary action.
