Machine cover


Streamline cover design, the frame is made of thick square tube, the   cover is made of 2mm steel plate. There are totally 6 wheels to move the machine   easily.

Front door structure

Fully enclosed glass door, transparentpneumatic holder to support, ensure the operating and repairing space.

Machine top

Anti-explosion lamp

Surface treatment

Painted with white color

Flux spraying

Spray   nozzle

Spray range:20~65mm,adjustable,nozzle height: 50~80mm adjustable,max. flow rate:100ml/min

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 system: stainless steel mesh frame+ double layers filter, recycle 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.

Rail parallelism

Width adjusting accuracy less than 0.2mm

Width adjust


C/V speed setting unit

Min.1mm/min 0-1800mm/min

C/V speed variation range

Electric closed-loop control, within 0-10mm/min

Conveying motor

TCG motor from Taiwan, 90w, with over-loaded protection function.

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 Taiwan, adjust 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 abnormal, temp. too high or too low;if 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.
