Special machines


With our in-line special assembly machines, we are able to press electromechanical components into the circuit board. The fusion process is supervised by a 100% force-displacement measurement. Thereby, the press-in tolerances are in the range of a few hundredths. We master the stitching of contact pins, blade strips, and other stamping parts with a fully automatic in-line machine,

which operates according to the magazine-to-magazine principle. SERO masters the visual comparison of very closely tolerated LED modules with an especially developed laser trimming machine. Hereby, the brightness of the LEDs is synchronised in an automatic control circuit through the trimming of series resistors with laser technology.


For high-volume special processes, we develop and build powerful special machines in close cooperation withselected suppliers.

For example, these special machines can contain the following work steps for the final testing and final assembly:

  • Separating the uses in single circuit boards
  • Automatic variant detection
  • In-circuit and/or function testing
  • Applying glue/thermal pastes/sealants
  • Assembly of housing parts
  • Screwing and caulking of all sorts
  • Lettering/labeling
