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

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

22kw

Install mode

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

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

Motorized

Wave adjustable height

0-18mm

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

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.
