Manufacturing - THT assembly

Newly developed assemblies have fewer and fewer THT components. Nevertheless, THT assembly will continue to be used for robust plugs and sockets as well as high-mass components in the future. Our electronics production consistently uses selective soldering processes for THT assembly. EBS-SYSTART GmbH has two soldering processes at its disposal for this purpose:

Manufacturing - THT assemblyMachine selective soldering

For optimal reproducibility and perfect step-through of the THT solder joints, EBS-SYSTART GmbH has opted for the ECOSELECT 1 selective soldering system from ERSA GmbH. This selective soldering system has the following system components:

  • Spray flux system
  • Various preheating modules
  • 2 solder pots with 15kg solder alloy each
  • Nitrogen Protective Atmosphere
  • Multiple process monitoring features

The biggest advantage of machine selective soldering is the thermal protection of the assemblies and the precise soldering of even inaccessible areas. Compared to a wave soldering system, the selective soldering system convinces with a significantly better energy balance. While the wave soldering system melts several 100kg of solder alloy, the ECOSELECT 1 only has a maximum of 15 kg, depending on requirements.

Already in the prototype phase, EBS-SYSTART GmbH relies on selective soldering in order to gain knowledge for later series production.

Manual selective soldering

Although EBS-SYSTART GmbH favours mechanical selective soldering, manual selective soldering cannot be avoided in cable assembly or in the case of very inaccessible solder joints, among other things. In order to achieve optimal and reproducible THT solder joints, regular training and audits are carried out with our production staff. Furthermore, we only use high-quality work equipment and tools such as soldering stations.

For rework work, we also have a hot air soldering station and infrared preheaters at our disposal.
