Abstract: The present disclosure relates to manufacturing techniques for manufacturing multiple semiconductor package assemblies on a lead frame, as well as a semiconductor package assembly manufactured using this method. The method reduces the distances or intermediate spacings between singulated semiconductor packages on a lead frame to a width equal to the width of a cutting tool which width is significantly smaller than the distance required in any known modelling encapsulation technique. Therefore, the method according to the disclosure allows to position more semiconductor packages on a lead frame on one process step. Accordingly, as the number of semiconductor packages per lead frame surface is increased, more semiconductor packages can be manufactured and singulated in one process step, which reduces costs and processing time.
