| Flux spraying |
| Spray nozzle | Spray range:20~65mm,adjustable,nozzle height: 50~80mm
adjustable,max. flow rate:100ml/min |
| Air circuit | Acid and alkali resistant air pipe, the brand is SMC from Japan. |
| Nozzle moving system | Step motor to drive, Mitsubishi PLC, with proximity switch and
entrance sensor to control, according to the coming PCB’s speed and
width, the spraying system can detect and starts to work. |
| Flux recycle system | Tray to hold the waste water and flux, can be draw out easily, make
maintenance very convenient. |
| Flux exhaust system | Exhaust system: stainless steel mesh frame+ double layers filter, recycle the flux
to maximum. |
| Isolated air curtain | Air pressure type knife, blow the redundant flux into the recycling
box, to avoid the flux to enter into the preheating zones, ensures
the safety. |
| Spraying box structure | Made of full stainless steel, easy to clean and repair.
Anti-corrosion, very durable. |
| Preheating |
| Preheating zone quan. | Preheating length is 1800mm, divided into 4 sections, supply
abundant adjusting space, very good for big PCB and complicated
PCB. Reduce the heat impact on PCB, improve the production
efficiency. |
| Temp. control method | Mitsubishi temp. collecting module, PID is very precise and stable. |
| Heating parts | The heaters are imported from Taiwan, heat up very fast, with long
life, small thermo lag; The heat is even in the zones. |
