Abstract
A method for controlling a contact angle between a glue and a surface of a substrate during manufacture of microchip packages is disclosed. The method includes applying a glue to a surface of a substrate, and placing an electrode in electrical connection with the glue. A potential difference is applied between the electrode and the substrate. The potential difference is applied across the glue and causes a contact angle between the glue and the surface of the substrate to be altered.
