The pioneering on-line selective soldering system in China


Electromagnetic solder pump
Pin-and-chain conveyor for PCB transport
Programmable conveyor width adjustment
Flux module with precision spray head
Bottom-side preheating via infrared
Top-side convection heating

Camera/screen for solder process monitoring

Selective soldering process:

Working Process:
Transport the PCB to flux module
Spray head move to programed area and flux is applied only to the soldering joint to be made
Top –side and bottom-side preheat
Programed electromagnetic pump soldering perfectly formed solder joint
PCB is transported out

Fluxing with high precision:

Sunflow 3 has programmable precision Flux Head to evenly apply the flux. The application pattern can be point or track in standard machine.The atomizing nozzle can be chosen when the flux area is large and precision requirement is low. The flux is targeted to be applied only to the solder joint to be made and the wettable area can be as small as 2mm.Thus flux consumption is reduced, saving cost.

Perfect preheating:

Sunflow 3 combines top heater and bottom heater and it still 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.

Stable High Quality Soldering:

Feature and advantage
Electromagnetic solder pump
Stable wave height
Quick-change solder nozzles
Special solder nozzle (can use 2 months)
Low maintains required

Chain—roller 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.
