Automatic Selective Soldering Machine 5kw Select Solder Machine

Online Independent Selective Soldering Machine SUNFLOW S

    Selective wave soldering is a special form of wave soldering applied to PCB plug-in through-hole soldering. Selective wave soldering generally consists of three modules: flux spraying, preheating, and soldering. The flux nozzle moves to the command position according to the pre-programmed program, and selectively spray the position to be welded. After the PCB is preheated by the upper and lower preheating modules, the welding module performs welding according to the programming path.
 
Application range:

    Selective wave soldering is mainly used in high-end electronic products such as military aerospace, automotive electronics, railway products, switch power supplies, etc. It can meet the through-hole soldering requirements of multi-layer PCBs with high soldering requirements and complex processes.
 
Features:

• Independent R&D electromagnetic pump
• Roller conveyor system, increase the welding space
• Modular design, easy to maintain
• Display welding status throughout the whole process

Overall diagram:

Selective soldering process:

• Deliver PCB to the specified position
• According to the set program to heat and solder PCB
• PCB out

Basic machine module:

• Preheat Module
• Soldering Module
• Conveyor System

Basic working principle: After the PCB is moved to the specified position according to the program set in advance, after preheating, the platform drives the electromagnetic pump to move to the area which needs to be soldered according to the pre-set program, and then solder.
 
Selective soldering system introduction:
Fast and comfortable programing:

• A variety of programming options are available
• Different parameter for every soldering point
• Offline programing
• Process data record

Smooth conveying system:
    Conveyor System combines chain and roller transports. Chain transport system is chosen in flux and preheating module. The soldering module use the roller transport which performs good in location board and repeatability
High precision spray system:
    The standard machine uses a precision drop nozzle with diameter of 130μm, which can evenly spray the flux to the required soldering area. The minimum spray area is 3mm, saving at least 90% flux compared to conventional spray
Perfect preheating system:
    Combine stop heater and bottom heater and it sill performs perfectly even for the lead-free soldering or multi-layer boards. Top convection heater has been proved by Sun East Reflow machine for many years and it can offer an even temperature distribution over the complete
board. Bottom IR emitter heater provides optional heating area according the custom board. At the same time, another top heater covers the soldering module and it can maintain the board temperature in all the cycle time.
