AIM Solder is a global manufacturer of halogen-free solder products, including halogen-free solder paste, flux and cored wire.
Contact us with any questions about our line of halogen-free solder materials.
WHY ARE HALOGENS USED?
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.
WHY HALOGEN-FREE?
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. In response to this concern, we offer a full line of halogen-free solder assembly materials.
WHAT IS HALOGEN-FREE?
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 in solder products, as shown below.
