5. The lower heating adopts "infrared +. Hot air" mode, which can effectively penetrate the PCB and heat the pad on the welding surface; At the same time, in order to prevent the non-uniform heating of pure infrared, the hot air circulation is increased. This not only enhances the heating capacity, but also ensures the PCB heating uniformity. 6. Segmented layered cooling system, up and down cooling mode, can effectively control the cooling rate, PCB outlet temperature is less than 50 degrees. 7. Synchronous rack and rail transmission mechanism to ensure the accurate width adjustment and high service life of guide rail. 8. The computer-controlled automatic lubrication system can automatically lubricate the transmission chain by setting the refueling time and refueling amount through the computer. 9. Integrated control window, computer switch, electric width adjustment, test curve, print curve and data transmission are easy to operate 10. Curve test and curve analysis function can analyze the maximum temperature, interval time, heating and cooling rate, which is convenient for process adjustment. 11. The operating system with password management can prevent irrelevant personnel from changing process parameters, and the operation recordmanagement can trace the change process of process parameters to facilitate the improvement of management. 12. Windows 7 Windows operation interface, Siemens PLC + LCD computer control system, with high security function 13. Rosin recovery system, rosin directional flow to the storage bottle, replacement and cleaning is very convenient. Stainless steel tube is used to transfer waste gas, life-long maintenance free. 14. The optional nitrogen distribution system and cooling system of chiller are available. When the nitrogen consumption is 20m3/h, the oxygen concentration in welding area is lower than 500ppm
