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 |

|||
|
|
|
● All hot air modules are for better temperature uniformity. |
|
|
● For standard, only lower part have heating modules and upper part is an option. |
| 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 ● No easy to deform when heating. ● Well contact with heater for more uniform heating. Used graphite for insolation ● anti-moisture and anti-corrosion. |
|
|
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 week |
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
|
|
 
|
|
|
>Filled with nitrogen to reduce the use of local tin slag device ,effectively reduce customer operating costs
>Local nitrogen filling device |
