Spray nozzle

Spray range:20~65mm,adjustablenozzle height: 50~80mm adjustablemax. flow rate:100mlmin

Air circuit

Acid and   alkali resistant air pipe, the brand is SMC from Japan.

Nozzle   moving system

Step motor to   drive, Mitsubishi PLC, with proximity switch and entrance sensor to control,   according to the coming PCB’s speed and width, the spraying system can detect   and starts to work.

Flux recycle   system

Tray to hold   the waste water and flux, can be draw out easily, make maintenance very   convenient.

Flux exhaust   system

Exhaust   systemstainless steel mesh frame+ double layers filterrecycle the flux to maximum.

Isolated air   curtain

Air pressure   type knife, blow the redundant flux into the recycling box, to avoid the flux   to enter into the preheating zones, ensures the safety.

Spraying box   structure

Made of full   stainless steel, easy to clean and repair. Anti-corrosion, very durable.


Preheating   zone quan.

Preheating   length is 1800mm, divided into 4 sections, supply abundant adjusting space, very   good for big PCB and complicated PCB. Reduce the heat impact on PCB, improve   the production efficiency.

Temp.   control method

Mitsubishi   temp. collecting module, PID is very precise and stable.

Heating   parts

The heaters   are imported from Taiwan, heat up very fast, with long life, small thermo lag;   The heat is even in the zones.

Preheating   power


Install mode

The heating   module adopts drawer design, easy to replace and repair, make the maintenance   very convenient.



Made of aluminum, wear resistant and without distortion.

Conveying   motor

Panasonic motor from Japan

Solder pot

Low   oxidization design

High quality   solder pot, the heat is very steady. Adopts liquid solder flow design, reduce   the impact oxidization, especially for small PCB.

Economical   running

Reduce the   power consumption

Moving   method


Wave   adjustable height


Wave motor

TCG motor   from Taiwanadjust the wave height with frequency conversion.

Preheating   parts

Adopts the stainless steel heaters from Taiwan, with long life and power saving up to 40% daily.


Cooling   method

Adopts high   power centrifugal fan, reduce the air bubble and solder pad stripping

Automatic finger cleaning

Imported   premium pump, can wash the fingers from both sides. Propyl alcohol to clean   and can be recycled.

Control software

★Automatic alarm function for failure:thermocouple abnormaltemp. too high or too lowif preheating system or solder pot is abnormal, the heating stops.

★Preheating temp., solder pot temp., conveyor   speed, spraying and cooling can be controlled separately.

★One week automatic power on/off setting three times one day

★The emergency stops are in front, rear of the   machine, press them in case of any emergency.

★UPS and timer are available for each model.

★Smema connectors are available at both entrance and exit.
