Background about Halogen free

In the case of solder material, halogens such as Cl, Br, etc. are used in the flux to improve solder wettability and workability. However, dioxins, which is harmful to living things, may be generated when incinerating an electronic board containing halogen, Cl or Br.
Halogen free is for measures of dioxin, to try to regulate the halogen to be used for the electronic board.
