The invention regards a press for soldering multilayer stacks for printed circuits, with an outer muffle that encloses soldering chambers where multilayer stacks are arranged to be heated, inducing a magnetic flux. For such purpose, the press is provided with an inductor having winding form which is arranged on a mobile piston adapted to apply a force on the multilayer stack, such to generate a magnetic flux at its interior that is spatially uniform and regular over time.

An electromagnetic stamping apparatus includes a work platform configured to load a work piece. A stamping component is coupled to the work platform and has a first position and a second position. The stamping component includes a stamping rod and a stamping head. The stamping head stamps the work piece on the first position. An electromagnetic device is coupled to the stamping rod and generates a magnetic force according to an alternating current to push the stamping component to the first position to make the stamping component stamp the work piece. A compression spring pushes the stamping component to the second position according to the restoring force of the compression spring. Wherein, the magnetic force is greater than the restoring force of the compression spring to make the stamping component stamp the work piece twice in every waveform period of the alternating current.
