PCB scrap

From a professional point of view, waste printed circuit board is a mixture of glass fiber reinforced resin and a variety of metals, which is a typical electronic waste. Once the circuit board is abandoned, it will do great harm to our ecological environment and human health. At present, the recycling methods of waste printed circuit boards generally adopt the methods of direct burial, incineration, washing and cracking, which is not allowed by the national environmental protection policy. In the world, the best way to recycle waste printed circuit boards is physical recycling. The most significant advantages of this method are low environmental pollution, high comprehensive utilization rate and high added value, which is the inevitable development trend of electronic waste treatment in the future; its disadvantage is that the treatment cost is higher than that of incineration or washing. The characteristics of BPC determine that the recycling process is difficult.
