Are lead-containing solders being phased out for all engineering applications?

Lead is NOT being categorically phased out but the use of lead (and cadmium) is being increasingly recognised as being undesirable both in terms of the long term environmental impact and recyclability of products. The End of Life Vehicles (ELV) Directive (2000/53/EC), the RoHS Regulations (2002/95/EC) and WEE Directive (2002/96/EC) prevent the use of certain hazardous substances including lead (and cadmium) containing materials. The use of leaded solder in potable water systems has also been prohibited in Europe and in many countries worldwide.
