Feature:

Overview of program advantages:

• All in one machine, can accommodate 3 boards or 3 pallet, one in spray flux, one is preheating, another in soldering, get bigger production yield.
• Individual spray flux table & soldering table.
• High soldering quality.
• SMEMA in line connection capable.
• 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.
• 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.

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: dual solder pot

• one solder pot system with individual temperature control, N2 temperature control, wave height control. All installed in one same table. The distance between two solder pot can be adjusted.
• 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.
