Main technology parameters Max power: 10KW Pot capacity: 240Kg(Sn63Pb37); 200(Sn100%) Max PCB size: 250X300mm (max) Temperature range: 200-320 degree LED display Preheating temperature: 100~190 degree Height range of wave crest: 5~10mm Melting time: 80min Flux spray: froth Power supply: 380V 3 phase (please connect power to the ground) Transmission speed: 0.5-3m/min Dimension: 1450X800X320mm Net weight: 170Kg Working Principle Working principle of wave soldering machine TB680 is below: It is out and home, put the PCB on the pallet, the pallet and PCB pass flux spout, the flux is spray on the PCB, with pallet moving, PCB are in preheating, when the preheating time is ok, the pallet will go back and then solder, after soldering it will go back original location, the welding process is finished. Function There are 6 parts: Flux, preheating, soldering, electrical controlling, exhaust unit and convection unit. 1. Flux Flux parts are made of air pump, air tube, pin valve, filter, froth tube and flux box. Flux There is flux belt on the froth tube, PCB whose side has chips is on the top and touch flux, the side will has flux film. 2. preheating It is made by melt board with resistor to provide heat for PCB. 3. soldering It is made by tin pot, heating board, wave pump and tin. Soldering 4 electrical controlling With PLC controlled, transmission speed, solder temperature, preheating time and others can be adjusted and controlled. Working principle is shown in Figure 4. Figure 4 electrical controlling 5 exhaust unit It is made of cover, air fan, air cover and air tube. All exhaust generated in soldering will be eliminated. 6 convection unit It is made of chain, rail, drive and pallet. PCB will be sent in flux unit, preheating unit and soldering unit by convection unit.
