Product details
Part1: motion system
Self design motion table with cast aluminum, lighter weight with quick motion speed.
Panasonic servo motor & driver provide stable driving power, with screw pole & linear guild rail for guidance. Precious position, less noise, stable movement.
With dust proof plate above motion table, so to avoid flux or solder drop to damage ball screw.
Part 2: fluxing system
Standard equipped with imported jet valve to get precious fluxing result with small flux dot, please note flux solid content should be less than 10%.
Flux is stocked by PP plastic pressure tank, make sure pressure stable without influenced of amount of flux.
Part 3: Preheat
At conveyor top & bottom equipped with IR preheating. Position is adjustable.
IR heater of Top
Heating ratio is adjustable by PC, from 0 ---100%
Part 4: dual solder pot
Tin furnace independent control of tin temperature, nitrogen temperature, peak height.
Solder temperature, N2 temperature, wave height, wave calibration etc all able to set in software.
Solder pot is made of Ti, not leakage. With cast iron heater outside, robust & quick heat up.
Solder pot is wired with quick connector. When exchange solder pot without re-wiring required, just plug & play.
N2 online heating system, to wet the soldering perfectly and reduce the solder dross.
With solder level checking & alarm.
Part 5: conveyor
Stepper motor drive for fixed & movable conveyor.
With stainless steel roller for conveyor, not wearable with long term usage. Also make sure solder nozzle can approach to board’s edge 3mm.
With PCB clamping system at conveyor.
Applications:
Widely used in electronics manufacturing, consumer electronics, automobile electronics, communications equipment, aerospace, medical equipment, LED lamps, computers and peripherals, smart home, smart logistics, miniature and high power ratio electronic devices.
