Lead Free Wave Solder Machine E-THERM RW Series

Quick Overview

Industrial PC control System Long lifetime and Good heat uniformity of solder pot Special design to implement less solder residue generated Patented design of impeller & channel for improving soldering wave stability Spraying evenly and minimized the overlapping Convenience for maintenance.

Modularize Flux Spraying system

Modularize Flux Spraying system

●   The flux nozzle uses a stepper motor drive, which can flux coating.

●    The spray system of modular design, the nozzle is always vertical guide rail, ensure good penetration of PCB flux.

 
Flux spraying is perpendicular to the PCB

●     Spread more even on PCB                    
●     Enhance flux penetrating property to the holes                  
●     Improve the adhesiveness of the solder metal                    
●     Effectively reduce the customer’s operating cost

Segmented transport rail design ,60kg rail transport capacity

●   Segmented transport rail design ,60kg rail transport capacity.

 

The transportation system adopts floating structure

●   The transportation system adopts floating structure, new 

type support profile, good strength, titanium alloy double 

hook claw, patent aluminum rails, long service life.

 
Modularize preheating system

●     Plug in and remove connector easily

●     Drawer type structure that easy to install or disassemble to maintain

Modularize solder pot

●     Plug in and remove power source and thermocouple easily

●     Standard solder pot, suitable different models and PCB size

●     Manually in/out & up/down

10mm thickness  casting iron solder pot

10mm thickness  casting iron solder pot

●   No easy to deform when heating.

●   Well contact with heater for more uniform heating.

Used graphite for insolation

●   anti-moisture and anti-corrosion.

 

Insolation and large solder pot

Ceramic coating

●   smoother surface, anti-corrosion, longer lifetime.

Insolation and large solder pot

●   reduces heat loss.

●   make the solder temperature to be more uniform.

●   improves the solder pot heat storage capability.

 
Solder residue is limited < 0.4kg per hour. Cost saved by better utilization.

   Dynamic rotating cap isolate air and limit the oxidation.

 

  The oxidation reducing cover effectively control the wave flowing speed, lower the falling height and eliminate oxide.

Cap should be clean at least a weekSolder residue should be removed everyday

Solder residue should be removed everyday

 
Field feedback for wave soldering with N2

●   Short-circuit and incomplete weld are reduced.

●   PCB surface is clean and smooth, without oxidation, and few solid residues.

●   The welding spot is bright, clean, without oxidation and few flux residues.

●   The flux residues is largely reduced, compared with welding under air and the PCB has little adhesion.

●   In addition, the welding spot strength will be enhanced in principle, reducing return to factory repair and the machine using life will be prolonged.

                   Partial nitrogen charging device for solder pot


                        >Stainless steel porous pipe sprays nitrogen evenly and stably


                        >Nitrogen will be blocked below the PCB and from a low oxygen layer between the PCB and the

                           solder pot surface in order to achieve high welding quality and low oxidation.


                        >Since it is not closed area, oxygen  analyzer cannot be installed
