Abstract: An apparatus and method for producing spheroidal metal particles having high size and shape uniformity from a melt from a highly reactive metal melt, with the following steps: melting the metal starting material under a hermetic seal; transporting the metal melt in a closed granulating tube from the melting furnace to at least one melt outlet; discharging the metal from the metal outlet via a rotary plate in the form of discrete drops to a melt stream which disintegrates into drops by the time it strikes the rotary plate; conducting a shielding gas flow into the region of the melt exiting from the melt outlet, collecting the melt on the rotary plate in the form of discrete melt drop, solidifying the melt drops into granule particles by contact with the colder surface of the rotary plate, and conducting the granule particles off the rotary plate for packaging/further processing.

Abstract: A multi layer circuit board (MPCB) is disclosed that is comprised of a first layer and a fourth layer substantially parallel to the first layer. Pluralities of electrical contacts are formed on the first layer of the multilayer circuit board and are disposed in a first grid. The plurality of electrical contacts are divided into a first subset for routing within the first layer, and a second subset for routing within the fourth layer. A plurality of vias are formed between the first and fourth layers and each disposed adjacent at least one of the second subset of the plurality of electrical contacts, the plurality of vias having a spacing between each pair thereof larger than a smallest spacing between adjacent electrical contacts of the plurality of electrical contacts.
