Transition to Halogen-free Electronics

Abstract

While a fear on usage of human toxicity like solder is increasing, there is also an interest on human toxicity of halogen flame retardant. Bromine based flame-retardant is widely used as the halogen based flame retardant due to the cost and the performance. In many cases, the plastic components used for an electric device also use the bromine system flame-retardants for the flame retardant. Therefore, the change to an alternative material system is advancing. For example, it has started that changing the housing of the display monitor of a personal computer in the material, which does not contain bromine system flame-retardant. The epoxy resin, the main material of the Multi-layer Printed Circuit Board, includes Bromination epoxy (TBBA) for flame retardant. Although bromination flame-retardants, such as PBB and PBDE's, were previously used in, TBBA was chosen.
