Wave Soldering Machine KTU-350

Wave Soldering Machine KTU-350

Machine cover

Structure 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, transparent，pneumatic 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

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.

Transmission

Rail Made of aluminum, wear resistant and without distortion.

Rail parallelism Width adjusting accuracy less than 0.2mm

Width adjust Manually/motorized

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 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 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，temperature is 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.

Nitrogen protection system (option)

Standard N2 configuration includes nitrogen closed construction, pipes, N2 flow meter, water chiller and oxygen analyzer.

★N2 protection system, can prevent solder paste from oxidization, improving the moisture of soldering points, reducing the faults of soldering.

★Low nitrogen consumption design(10-20cbm/Hour), oxygen density can be keep between 300-1000PPM.

★Nitrogen can be reused after filtering, production cost is therefore saved.

★Nitrogen flow rate and oxygen analyzing system are easy to be observed and adjusted by the flow meter and oxygen analyzer.
