The EU directive 2002/95/CE restricts the use of some substances, in particular lead,
in electronic products as of July 2006. Our equipment are used for routing, switching,
transmission, network management or network security in telecommunication applications.
There is a risk to consumer safety should these systems fail unexpectedly. It is not yet known,
however, how to extrapolate accelerated test data to predict field performance and this will
not be possible until lead-free solders have been in widespread use for at least five years.
The restriction on lead is of a great importance for PRESCOM, as lead substitutes must not
raise long term reliability issues for electronic boards and modules that PRESCOM produces.
Taking these difficulties into account,  the Annex of Directive 2002/95/EC exempts the use
of lead in solders for telecommunication network infrastructure equipment. The exemption
on lead solders will be used as long as the long term reliability of our equipment is fully guaranteed with alternative solutions. Nevertheless, all the components has been changed
with RoHS compliant parts since July 2006.
