Abstract:
The invention relates to a multi-chip module and a method for producing the same. The inventive module has a base substrate on a part of which signal conductor tracks and signal contact surfaces are arranged in at least one layer. The module further comprises a semiconductor component that is linked with signal conductor tracks and signal contact surfaces and that works in the signal range. The aim of the invention is to provide a highly integrated multi-chip module. To this end, power conductor tracks and power contact surfaces are arranged at least on part of the base support and in at least one layer. At least one power electronic component is provided that works in the power range and that is linked with a power conductor track, at least one power contact surface and at least one signal conductor track. The power conductor tracks have a larger diameter than the signal conductor tracks at least due to a higher thickness.
Abstract:
A method for mounting terminal on circuit board includes an applying process for applying solder paste (3) to a circuit board (1), a laying process for laying the connecting ends (4a) of terminals (4) having the connecting ends (4a) and non-connecting ends (4b) on the parts coated with the paste (3), and a heating process for melting paste (3) for soldering the connecting ends (4a) to the board (1). The method also includes a process for applying an adhesive (6) to the board (1). In the laying process, the connecting ends (4a) are brought into contact with the parts coated with the adhesive (6). In the heating process, the paste (3) is melted by heating in a state where the connecting ends (4a) are stuck to the board (1) with the adhesive (6).
