Abstract: An improved encapsulation method is proposed for the encapsulation of a substrate-based package assembly, which can help to prevent mold flash over exposed package surfaces after encapsulation process is completed. The proposed encapsulation method is characterized by the forming of a cutaway portion in a solder mask over the substrate along a seam line between the solder mask and the molding tool that would exist between the solder mask and the molding tool when the semi-finished package assembly is fixed in position in the molding tool. During encapsulation process, the cutaway portion defines a constricted flow passage to the injected encapsulation material; and consequently, when the encapsulation material flows into this constricted flow passage, it would more quickly absorb the heat in the molding tool, thereby increasing its viscosity and retarding its flow speed.
