AIM is a leading global manufacturer of tin-lead and lead-free solder assembly materials for the electronics industry.
AIM's product line includes a full range of solder products and a wide variety of lead-free solder alloys.
Halogens are added to organic materials as a fire retardant. The common halogens used only give off bromides with elevated temperatures, decomposing and releasing bromine in order to extinguish fires. These are toxic and corrosive when decomposing. However, they are benign when at ambient temperatures.
Many Non-Government Organizations (NGOs), which focus on global environmental concerns, are exerting pressure on electronic equipment providers to eliminate halogens. REACH and RoHS are banning the use of halogens. The concern is with the end-of-life disposal of products containing the halogens, in particular, disposal through incineration as a recovery method.
There are many committees, consortiums, and organizations working on this issue. Some organizations have started publishing maximum limits to be the determining factor. These can be 900 ppm of either Br or Cl and a combined total of 1500 ppm. Others have set 1000 ppm of either Br or Cl. There is an attempt to have a defined limit on halogen content, as shown below.
Br 900ppm max Cl 900ppm max Br+Cl 1500ppm max
