Nitrogen Wave Soldering Machine KTN-450

Products description

Infrared heating method, by this method, the air won't flow, It can keephigh level nitrogen levelin soldering part. easy to reach 30-50 PPM. High nitrogen level make thesolder clean and very few dross nearly no, and for the PCB surface it's very clean, no dross on the surface, soPCB no need cleaning, no need cleaning machine, save many cost for cleaning. High nitrogen level also make the solder more few empty holes inside the solder.

Machine coverStructureStreamline 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 structureFully enclosed glass door, transparent，pneumatic holder to support, ensure the operating and repairing space.Machine topAnti-explosion lampSurface treatmentPainted with white colorFlux sprayingSpray nozzleSpray range:20~65mm,adjustable，nozzle height: 50~80mm adjustable，max. flow rate:100ml／minAir circuitAcid and alkali resistant air pipe, the brand is SMC from Japan.Nozzle moving systemStep 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 systemTray to hold the waste water and flux, can be draw out easily, make maintenance very convenient.Flux exhaust systemExhaust system：stainless steel mesh frame+ double layers filter，recycle the flux to maximum.Isolated air curtainAir 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 structureMade of full stainless steel, easy to clean and repair. Anti-corrosion, very durable.PreheatingPreheating length is 1800mm, divided into 4 sections,Infrared heating method, by this method, the air won't flow, It can keephigh level nitrogen levelin soldering part. easy to reach 30-50 PPM. High nitrogen level make thesolder clean and very few dross nearly no, and for the PCB surface it's very clean, no dross on the surface, soPCB no need cleaning, no need cleaning machine, save many cost for cleaning. High nitrogen level also make the solder more few empty holes inside the solder.Temp. control methodMitsubishi temp. collecting module, PID is very precise and stable.Heating partsThe heaters are imported from Taiwan, heat up very fast, with long life, small thermo lag; The heat is even in the zones.Preheating power22kwInstall modeThe heating module adopts drawer design, easy to replace and repair, make the maintenance very convenient.TransmissionRailMade of aluminum, wear resistant and without distortion.Rail parallelismWidth adjusting accuracy less than 0.2mmWidth adjustManually/motorizedC/V speed setting unitMin.1mm／min 0-1800mm／minC/V speed variation rangeElectric closed-loop control, within 0-10mm／minConveying motorPanasonic motor from JapanSolder potLow oxidization designHigh quality solder pot, the heat is very steady. Adopts liquid solder flow design, reduce the impact oxidization, especially for small PCB.Economical runningReduce the power consumptionMoving methodMotorizedWave adjustable height0-18mmWave motorTCG motor from Taiwan，adjust the wave height with frequency conversion.Preheating partsAdopts the stainless steel heaters from Taiwan, with long life and power saving up to 40% daily.CoolingCooling methodAdopts high power centrifugal fan, reduce the air bubble and solder pad strippingAutomatic finger cleaningImported 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.
