The problem is that solder traditional joints tin-lead solder. In recent years, people made a lot of work, while maintaining circuit performance and board life, with a tin-silver-copper (SAC) solder replace the tin-lead solder. However, designers in removal of lead achieved success, but ignored the board design an equally important issue. Most of the circuit board are reinforced material containing brominated flame retardants (PBB and PBDE). Therefore, even if the circuit boards lead-free, but because containing PBB and PBDE, may still be unacceptable. testing the material, not the circuit Niton ROHS detector, Sheng Ding instrument (online consultation), ROHS provided by the Dongguan City Ding Sheng Precision Instrument Co., Ltd.
