Circuit board to take off the tin electronics equipment With electronic components of the circuit board by conveyor to close the wind into the feeding roller and feed preheating chamber. The device containing waste gas exports the back-end and exhaust gas treatment device, again for exhaust gas purification, discharging standard. Tin rate can reach about 99% off the equipment, electronic components rate can reach about 95%. Through this device can take electronic components of the circuit board is divided into: solder, electronic components, electronic components and circuit board larger.
