Uni-body Plug-in Power Package is the main packaging form for power hybrid integrated circuits, whose base material is CRS or OFHC which have good thermal conductivity.
Heat caused from internal circuits could be transferred to outside quickly in order to avoid device failure caused by heat collection. According to current transmission requirements, 4J50 copper core leads can be used to reduce leads resistance. Package leads are usually introduced in dual-line plug-in layout or introduced from package sides.
Dimension of this type of package is relatively larger and it weighs heavier, so flange installation structure is often applied. Package leads are often gold plated. Applied sealing method of Uni-body Plug-in power package is parallel seam welding, and etched step type lids are used as package covers.
