Abstract
In the packaging of devices, such as active and passive electronic devices, the devices can be selectively hermetically sealed or non-hermetically sealed, as desired, using to a large extent common apparatus. In the limit, only the fusion sealing for hermetic devices and plastic encapsulation for non-hermetic devices need be carried out on separate machines. This is obtained by use of a particular form of lead frame, common for both forms of devices, with common apparatus and steps prior to and following the sealing or encapsulation.
