Laser soldering addresses lead- free legislation

December 2005
Industrial Laser Solutions;Dec2005, Vol. 20 Issue 12, p8
The article reports on a legislation named Removal of Hazardous Substances, which seeks to remove lead from most of the products sold in the European Union. After bringing this legislation in action most of the products produced after July 2006 in the European Union will be lead free in content. The means of eliminating lead from the solders used in printed circuit boards is the main area of concern for manufacturers, particularly in the electronics sector. Laser soldering has the advantage that the head is applied only where it is required-at the joint itself. Also, laser soldering is fast-much more power can be applied to the joint than using conventional "hot iron" soldering and so each joint can be completed in a fraction of a second.
