Self-aligned transition between a transmission line and a module

A module destined to form a self-aligned transition with a transmission line and provided with an arrangement of solder particles that are configured to match and to be soldered by reflow to soldering pads arranged on the rim of an open end of the transmission line designated for connection with the module or on an intermediate element fixed to or configured to be fixed to such a rim of the transmission line.

An intermediate element fixed to or configured to be fixed to a rim of an open end of a transmission line designated for connection to a module, said intermediate element comprising an arrangement of soldering pads configured to match and to be soldered by reflow with solder particles arranged on a module to be connected to said transmission line, thereby providing a self-aligned transition.

A transmission line configured to provide a self-aligned transition with a module and comprising an arrangement of soldering pads configured to match and to be soldered by reflow with solder particles arranged on such a module, said arrangement being disposed on a rim of an open end of the transmission line.

A system comprising:

• a transmission line configured to provide a self-aligned transition with a module and comprising an arrangement of soldering pads configured to match and to be soldered by reflow with solder particles arranged on said module, said arrangement being disposed on a rim of an open end of the transmission line;
• and
• a module destined to provide the self-aligned transition with the transmission line and provided with the arrangement of solder particles that are configured to match and to be soldered by reflow to the soldering pads arranged on the rim of the open end of the transmission line designated for connection with the module.

A method for forming a self-aligned transition between a transmission line and a module to be connected to said transmission line, comprising the steps of:

• a) providing the module with an arrangement of solder particles in an area designated for the connection of said module to the transmission line;
• b) providing a rim of an open end of the transmission line designated for the connection to the module with an arrangement of soldering pads corresponding to the arrangement of solder particles on the module;
• c) placing the module with the solder particles thereof onto the soldering pads and connecting the module to the rim of the open end of the transmission line by reflow soldering.
