Standard cold air knife to prevent flux fog from spreading outward, reducing pollution. Double-wave control adopts infinite-frequency conversion technology, which can control the wave peak height independently.1 / 4HP high power peak motor, maximum peak height up to 15mm. With overtemperature sound and light alarms and an emergency braking system, all motors have overload protection.
The transportation system adopts infinite electronic adjustment and closed-loop control, with stable and accurate speed. A pressure-assist device is provided at the inlet end to avoid slipping when the PCB enters. The forced natural cooling system can meet the cooling slope requirements of the lead-free process. The track angle is manually adjusted for easy operation. The flux nozzle is driven by a stepper motor to ensure uniform flux coating. With the modular design of the spray system, the nozzle is always vertically tracked to ensure good penetration of the PCB.
The preheating zone uses hot air heating; the whole process is at high temperature, with glass protection and temperature stability. The preheating system is controlled by PID, and the temperature curve is stable, which is convenient for finding the best setting for various lead-free processes
