A device for and method of packaging electronic components (1) using injection-molding. For this purpose, a multiplicity of components (1) are arranged in predetermined positions on a first side (2) of a leadframe (3). The leadframe (3) has interconnects (5) with contact terminal areas (6) for connecting to contact areas (7) of the electronic components (1) and contact vias (8) to external contacts on a second side (10) of the leadframe (3). In this case, the leadframe (3) includes a ceramic substrate (11) with a first side (2) having edge regions (12) configured with a ductile, annular metal layer (13).
