series flame retardants is forbidden.

1. Regarding the two types of "environmentally-friendly printed

circuit boards"
Halogen-free printed circuit boards
1. Bromine-series flame retardants previously used have been changed to phosphor compounds, etc.
which maintain functionality but do not emit poisonous gases (dioxins) when burned.
2. Those using halogen-free ink which have removed the halogens contained in the ink pigment.
Lead-free printed circuit boards
1. Those in which tin, silver, and copper solder has replaced tin and lead solder.
2. Those to which plating has been applied.
3. Water soluble pre-flux items in which tin and lead solder has been replaced by those in which
copper surfaces are protected by organic coatings.
