Lead free and RoHS

From 1st July 2006 the EEC directive (2002/95/EC), better known as RoHS (reduction of Hazardous Substances) has made it mandatory for PCBs to be made using a lead free process as lead is one of the materials on the banned substance list. Recognising the importance of this directive Challenge Electronics invested heavily in the machinery and technology necessary to produce lead free PCB assemblies. In particular two new soldering machines were purchased which are capable of safely and reliably producing high quality lead free solder joints.

The result is that we now have the following fully operational capabilities:

  • Lead free flow-soldering on a dedicated state of the art Contax ATF 13-25 lead free flow-solder system with spray fluxer. This machine suits conventional PCBs and mixed technology PCBs (SMD + conventional).
  • Lead free reflow soldering on a QUAD ZCR lead free SMD reflow tunnel with profiling system. This machine suits SMD reflow assemblies.

In addition we have maintained our Tin/Lead flow-solder and reflow soldering lines to suit customers that have permanent or transitional exemption from the RoHS directive.
