Abstract
A method and device for providing a gate blocking material. Specifically, a method for molding a substrate having known good and bad sites thereon, by blocking the gate area of the bad sites during the molding process. A blocking material or an injection pin are used to interrupt the flow of molding compound through an injection molding system, and thereby prevent molding compound from flowing onto the known bad substrate sites.
