摘要:
The invention relates to recovery of tin-lead solder from electronic printed circuit board scrap. The scrap is placed in a liquid-permeable and/or gas-permeable container, which is placed in a liquid or gaseous heat-transfer medium heated to or above the melting temperature of the tin-lead solder. After the tin-lead solder is melted, the heat-transfer medium is removed from the container, then, by means of rotation of the container, the melted tin-lead solder and the remains of the heat-transfer medium are removed from the container. The device comprises a hollow container, which is mounted so as to be capable of rotation and is designed in the form of a body of revolution, and is liquid-permeable and/or gas-permeable in a radial direction from the axis of rotation. The container can be designed in the form of a drum, which can be vertically displaced and has perforated side walls.
