Abstract:
An apparatus for inserting underfill material into a space between an electronic component and a substrate, comprising:an underfill tube having a first end in contact with the substrate and a second end coupled to an underfill source, the tube including a side opening in engagement with a first side of the electronic component; a vacuum tube having a first end in contact with the substrate and a second end coupled to a vacuum source, the tube including a side opening in engagement with a second side of the electronic component; wherein a vacuum generated within the vacuum tube causes underfill material to flow from the underfill tube into the space between the electronic component and the substrate; and a system for determining when the space between the electronic component and the substrate has been filled with the underfill material to a predetermined level.
