Abstract:
A hybrid circuit suitable for attachment to a circuit board using surface mounted devices (SMD) technology, said hybrid circuit comprising a terminal arrangement having a plurality of terminal pins having a pin termination for soldering said hybrid circuit to the circuit board, in which at least part of the heat developed on the basis of the power consumption of said hybrid circuit can be dissipated via said terminal pins to the a circuit board, and wherein an at least one terminal pin is provided with a thermal transition resistance to said hybrid circuit that is higher than that of the other terminal pins, said at least one terminal pin is provided by an at least one intermediate layer of glass distinct from said hybrid circuit under said pin termination of said at least one terminal pin so that said at least one terminal pin does not reach the melting temperature of the solder used at a given power consumption.
