Inline Selective Soldering Machine FLEX-i2

Machine working concept: PCB is moved by X/Y table with servo motor, Solder pot is moved in Z with servo motor, drop jet flux is moved in Z with aircylinder.



Spray Flux

Spray Flux

Flx-DropJet : Standard equipped with drop jet valve from Germanny originally, which can meet dia 2mm flux dot dimension.

Selecting Soldering Pot

Selecting Soldering Pot

● Titanium soldering pot, 100% capable for lead free application. Standard equipped with mechanical pump, easy for maintenance.

● N2 direct heating system is standard equipped,enhance the wetting ability for lead free sodlering.


Live camer

Sod-ProcMoni: Without open machine's door, operator can see soldering process in real time.



Pre-TPRE: Standard equipped with upper preheating zone, to reduce the temperature drop on PCB during soldering, especially for thick PCB or heat absorber component,and preheart time & heating ratio(%) can be set in software.option with bottom preheat.


Solder nozzle

Sod-WetNoz: Standard equipped with wet nozzle for customer's universal applicaiton. Can also design solder nozzle according cusotmer's application.

Software System:

Solder It

Solder it” is windows10 based software.  With board scanned picture or Gerber file,  “POINT AND CLICK” to “draw and drag” motion path easily, make the initial programming in less than 10 minutes.

Path programming :

Point and Click

“Point and Click”

● to draw path with scanned picture as background, easiest way for path programming.

Solder path editing

Solder path editing:

● Moving speed, Z height, wave height, Dwell time, wave slope speed etc are editable, get max flexibility to fit different type of components on the board. Empth move time, site working time, total cycle time are estimated once path programming finished. Easy for balance production line.

Maintenance & replacement assisting function

Maintenance & replacement assisting function:

● we know how important the maintenance for a selective soldering machine. In the software, we list all maintenance job, time taking, comsumable parts life and remain life, etc. It can export to excel list, engineer can check what parts need to replace in next 3 month or 6 months, in this way to they can prepare everything in advance.
