Service | Rohs


Since the 27.01.2003, the EC Directive 2002/95/EC has regulated the use of hazardous substances in devices and components = RoHS (Restriction of the use of certain Hazardous Substances) within the European Union.

This Directive came into force on the 01.07.2006 and has been adopted as a valid national law (Waste Electrical and Electronic Equipment Law) abbreviated as ElektroG (Germany).

Amongst other things, the RoHS includes the lead-free soldering of electronic components.

For reasons of operational safety, monitoring and control instruments and electronics for military use are excluded (for the time being) from this directive.

The reasons for this are:

  • – Better elasticity of lead-containing soldered connections in the event of vibration and other mechanical stresses
  • – Lower soldering temperatures than with lead-free soldering and therefore lower associated stress levels of the electronic components
  • – Finer surface structure of the soldered areas
  • – Longer service life and storage potential
  • – Lower hand-soldering temperatures for repairs and when carrying out maintenance tasks

For these reasons Comtronic has not converted all products to lead-free soldering. But in the meantime, due to market conditions most electronic components which are processed on printed circuit boards are suitable for lead-free soldering and evermore new products are offered on the basis of lead-free soldering when they are introduced to the market.

Our sales and quality departments are gladly at your disposal for all questions relating to the subject of RoHS compliance.
