Basic machine module:

·Flux Module

·Preheat Module

·Soldering Module(within ner6mm nozzle)

·Conveyor System

Working Process:After PCB is moved to flux area, the spray head is targeted to the programed position and the flux is applied only to the solder joint to be made.After preheating, the electromagnetic pump moves to the target area and solder joint is made.


Conveying system:

Conveyor System combines chain and roller transports.Chain transport system is chosen influx and preheating module.The soldering module use the roller transport which performs good in location board and repeat abi ity.


Fluxing with high precision:

The SUNFLOW 3 standard machine adopts precise nozzle with 130pm diameter which is imported from Germany and can uniformly spray flux in the required welding area.The minimum injection area is3mm which saves atleast 90%flux compared with the traditional spraying.


Perfect preheating:

Sunflow 3 combines top heater and bottom heater and its til 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 I Remitter heater provides optional heating area according the custom board.At the sametime, another top heater covers the soldering module and it can maintain the board temperature in all the cycle time.


Stable high quality soldering:

Sunflow 3 offers electromagnetic pum system.There is no moving mechanical parts in pump system, so dust is little in process.The pump offer constant flow which translates into stable wave height.The soldering module has high precision axis system to ensure the accurate soldering path and with particular process, the system will eliminate the chance of bridging.Besides, process monitor screen and automatic soldering wave height detecting are very friendly for users.


Fast and comfortable programing:

1.Gerber file program

2.On-line screen program

3.Picture program

4.MARK plsitinoning and recognition (Option)
