Automatic Online Selective Wave Soldering with Dual Wave Soldering and SEL-31EM DIP Selective Reflow Soldering Machine For DIP Production Line
Overview of programme strengths:
(1) Integrated full-functional model, the whole motion platform integrated spray and welding, compact space.
(2) PCB plate fixed, spray and welding platform moving.
(3)High welding quality, greatly improve the pass rate of welding.
(4) Modular design of SMEMA online transportation, support customers for flexible line formation.
(5) Full PC control. All parameters can set in PC and saved to PCB menu, like moving path,solder temperature, flux type, solder type ,n2 temperature etc, best trace-ability and easy to get repeat soldering quality.

Machine explanation
Part1: Software
All software system developed by company from USA, with our 8 years experience about selective soldering, base on Windows7 system, with good trace-ability
Use scanned picture as background for path programming, moving speed, dwell time, empty move speed, Z height , wave height etc all programmed for different solder site
Show solder process with live on camera.
Critical parameters are totally under monitoring by PC software, like temperature, speed, pressure etc.
Can upgraded to be with auto wave height calibration function, to check & calibrate wave’s height after every certain pcb, so to keep a very good stability of wave.
Can upgraded to be with Mark positioning function, to check PCB’s mark point after every certain pcb, so to be reduce the pcb’s position offset.
About PCB’s menu in soldering machine, all information will be stocked in one file. It will include PCB dimension and picture, used flux type, solder type, solder nozzle type, solder temperature, N2 temperature, motion path and each site’s related wave height
and Z height etc. When customer to solder same PCB, they can get full information about how it’s done in history, also easy for trace.
With LOG function, provide 3 level to enter software with different rights. Meanwhile, can record machine’s operation & alarm.
Part2: 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 3: 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 4: Preheat
At conveyor top & bottm equipped with IR preheating. Position is adjustable.
Heating ratio is adjustable by PC, from 0 ---100%
Part 5: solder pot
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 6: 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.
Part 7: machine chassis
Metal welding structure, with thick metal plate as base, so to reduce vibration and make machine more stable.
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.
