International Classification:

H01L 3902
H02G 1308

US Classification:

357 80

Abstract:

A leadless chip carrier for RF power transistors or the like is disclosed which includes a body of insulating material having two major surfaces and side walls joining the major surfaces. In a first embodiment, a pattern of conductive pads is deposited on one major surface. A pattern of conductive contact areas is deposited on the other major surface and distributed interconnecting portions of conductive material are deposited to connect the pads to the respective contact areas. In a second embodiment, larger pads and contact areas are provided on a beryllia substrate to provide a leadless chip carrier for RF transistors capable of handling 8 watts. In a third embodiment, a single slot is made conductive to provide the distributed interconnecting portion for one terminal, while in a fourth embodiment, the slot is changed to a plurality of small, tungsten-filled through holes to provide a virtually hermetically sealed leadless chip carrier for RF power transistors.

US Classification:

560 68

Abstract:

A process for preparing pure antihistamine tannate compositions. The antihistamine in the form of its free base is contacted with tannic acid in the presence of water for a period of time of about 5 minutes to 4 hours and at a maximum temperature such that not more than about 5 wt. % of the antihistamine tannate will be decomposed. Water is removed from the antihistamine tannate by freeze-drying.

Abstract:

Phenylephrine tannate compositions are disclosed wherein the phenylephrine tannate has a minimum purity level of at least 95%. The composition also contains a minor amount of water, but no significant quantities of organic compounds or solvents other than water are present. The phenylephrine tannate will have a density of at least 0. 6 g/cc.
