Based on the analysises of the structure and working principle of a micro-high-speed centrifugal pulverizer and research on the technical parameters of pulverizing,experiments on the pulverization of waste printed circuit boards of 10mm×10mm×1.

The paper reviews the composition of waste printed circuit board, the current available recycling technologies including incineration, acidic recycling, and mechanic recycling with an emphasis on the last one.

In this paper, four type of methods for waste printed circuit board reutilization are analyzed and compared.

With the rapid development of the electronics industry,how to recycle the discarded electronic circuit boards effectively has become a new topic.

Study on phenol-formaldehyde resin prepared from waste printed circuit boards;

Study on compositions of pyrolystic tar from waste printed circuit boards mixed with calcium carbonate

The mechanism and features of microwave heating and microwave technology applied to radioactive waste, waste circuit board, sludge, waste tyre are discussed, applicable prospect of microwave technology application in waste processing is also given.

The recovery method of waste circuit board depends on the property of circuit board,so it is very important for choosing the processing technology which makes out the compose and content of various material in the waste circuit board from the qualitative and quantitative angle.
