VACCINE COMPOSITIONS FOR FISH

摘要

An electronic device (10) encased within a moulded package body (11) has a leadframe (12) extending therefrom. In order to protect the leads (16) of the electronic device (10), a guard ring (14) is provided on the leadframe. By making the guard ring (14) independently of the moulded package body (11) and fitting it separately to the leadframe (12), one can deal with packages of any size in a simple manner and irrespective of the material of the package body (11).
