Latest Patents

One of Nezu's latest patents is focused on a circuit device and method of manufacturing the same. This invention involves a hybrid integrated circuit device where a conductive pattern, including pads, is formed on a substrate's surface. A first pad is designed to be relatively large to accommodate a heat sink, while a second pad is smaller for attaching chip components or small signal transistors. A notable feature of this invention is the formation of a nickel-plated film on the first pad's surface, preventing direct contact with solder. This innovation helps avoid the generation of a Cu/Sn alloy layer with poor soldering properties, instead promoting the formation of a Ni/Sn alloy layer that exhibits excellent soldering properties. Consequently, the occurrence of sink in melted solder is effectively suppressed.

Another patent by Nezu provides a hybrid integrated circuit device that allows for the formation of fine patterns while ensuring current-carrying capacitances. This device includes conductive patterns on the front surface of a circuit substrate, with circuit elements electrically connected to these patterns. The design features a first conductive pattern and a second conductive pattern that is thicker, with the latter including a protruding portion that extends in the thickness direction.
