We produce electronic products in medium-sized to large series batches on our cutting-edge SMD populating equipment.

The level of populating performance, repeatability, availability, population and soldering quality, and the automatic visual inspection meet the toughest requirements of our challenging clientele.

Just like SMD assembly, THT assembly is also performed in strict accordance with the specifications of IPC-A-610F. In the conventional population lines, the THT components are populated directly in solder frames in the circuit boards at state-of-the-art populating tables.

The in-line transport systems feed the solder frames through the wave soldering system and then back to the populating stations.

In the area of depanelization, we have mastered all of the current depanelization processes blindfolded:

  • Manual and semi-automated depanelization using rotary cutter
  • Semi-automated depanelization with impact cutter
  • Fully automated depanelization using cutting and stamping technology
  • Fully automated depanelization using cutting mills, including inline

Special Machines

With our customized in-line populators, we are able to press electromechanical components into the circuit board. The joining process is monitored with a 100% force-and-distance measurement, and press-in tolerances are in the range of a few hundredths of a millimeter.

Stitching of contact pins, knife blades, and other punched parts are mastered with a fully automated in-line system operating under the magazine-to-magazine principle.

Test systems

For less complex assemblies, and for multipurpose components, we design test lines that operate under the magazine-to-magazine principle.

With test systems developed in-house at SERO, we have an advantage in terms of automation level, test technologies, and testing costs.
