The optimal research on the technology of recovering metals from waste printed circuit boards was done. The method of pre-separating the solder was suggested.Many tests were done using different devices such as CNC atmosphere furnace to look for the most optimal condition of solder separation.The 250℃ of heating temperature and 5 minutes of heating time could realize the pre-separation of solder from the waste circuit boards.This pre-treatment could decrease the difficulty of separating other metals on the boards and increase the recovery rates of metals.
