Publication number: 20030161121Abstract: The idea of the invention is to form a cavity in a multilayer substrate at the point of the structure to be trimmed. This enables the embedding of tolerance critical components inside substrates, such as printed circuit boards, modules, and sub-systems. Trimming is done through the cavity using, for example, a laser. After trimming the cavity is easy to fill in with a suitable dielectric material, or to cover otherwise, e.g. by using a lid, or to leave the cavity uncovered.Type: ApplicationFiled: December 9, 2002Publication date: August 28, 2003Inventors: Olli Salmela, Ilpo Kokkonen

Patent number: 6600659Abstract: A new physical design for electronic devices (100) comprises a multi-layer stacked assembly (104-110) of a plurality of pan-shaped conductive units that form the layers of the assembly. Each unit is preferably formed from a single sheet of metal into which electronic components, such as an antenna array (208) or a filter array (314) of a transceiver, have been stamped, cut, or etched, and which is then bent around its periphery to form a pan shape. The pans are oriented to face the same direction, are stacked one on top of another, and are fixedly attached to each other by weld, solder, or adhesive. The electrical components defined by the different units are electrically interconnected in a connectorless manner, preferably by flanges (122, 124) formed in the same sheets of metal as the units themselves and extending between the units. Adjacent units in the stack define electromagnetically isolated chambers, e.g., for the filter array. Some layers perform double duty, e.g.Type: GrantFiled: March 9, 2000Date of Patent: July 29, 2003Assignee: Avaya Technology Corp.Inventors: Ron Barnett, Charles Joseph Buondelmonte, Ilya Alexander Korisch, Louis Thomas Manzione, Richard F Schwartz, Thaddeus Wojcik, Hui Wu
