Guangshengde Large Computer Lead free Double Wave Soldering Machine GSD-WD351C Structural Detail Diagram

Guangshengde large computer lead-free double wave welding machine GB-WD351C spray system features

● Lumina nozzle is adopted, and the spray range is 20~65mm. The height of the fan adjustable nozzle is 50~80mm, and the flow rate is 60ml/min

Adopting imported filters, control valves and pipe joints, digital display of air pressure. All gas pipes of spray system are acid and alkali resistant and anti-corrosion SMC gas pipes

● The flux spray system adopts the scanning spray mode, and uses the limit proximity switch and the plate feeding optical eye for combined control. According to the speed and width of the PCB, the inductive spray is automatically detected when the PCB comes to the plate. To achieve the optimal wetting range of the flux, imported nozzles and stepper motors, specialized drive control system, accurate and reliable; (Patent number: ZL 2011 2 0461844.8)

Stainless steel bent into shape is used as a tray under the nozzle to hold wastewater and flux, which can be easily removed for cleaning;

The exhaust system uses double-layer stainless steel wire mesh filtration to filter and recover excess flux based on the characteristics of the fluid

● It is equipped with adjustable direction and pneumatic air knife to blow the surplus flux during spray into the recycling box to prevent the flux from entering the preheating area and ensure production safety.

All stainless steel bracket, easy to clean and maintain. High anti-corrosion level and durable.

Characteristics of GB-WD351C soldering system for Guangshengde large computer lead-free dual wave soldering machine

1. The PCB board enters the soldering area of the tin furnace and automatically starts soldering. After soldering is completed, the wave crest stops automatically. (Patent number: ZL 2010 2 0056206.3)

2. The lead-free and environmentally friendly independent design of the tin furnace allows for easy and safe lifting and access, as well as easy cleaning;

3. The tin furnace is made of high-quality imported stainless steel and insulated with aluminum silicate insulation material. With an internal temperature of 270 ℃ and an external temperature of ≤ 60 ℃, the insulation effect is excellent and the safety is extremely high

4. 3MM thick lead-free stainless steel material, resistant to high temperature and corrosion, suitable for lead-free processes, with a long lifespan; Comes with a furnace liner as standard

5. The tin furnace adopts a 5-sided heating method, which heats up quickly. It is designed with automatic on/off time, and the heating time of the tin furnace can be produced in 70 minutes.

6. The tin furnace adopts imported high-temperature motors, stepless variable frequency speed regulation, independent control, and stable peak performance;

7. The heating of the tin furnace adopts high-speed PID external heating two-stage independent control, which heats up quickly and solves the problem of tin explosion in the tin furnace;

8. The soldering nozzle can be adjusted according to the width of the PCB board you want to pass through, reducing the area of ineffective soldering areas and minimizing the contact area between solder and air, greatly reducing the amount of solder oxidation. There is a deviation in the impurity content of tin bars and tin slag. Suitable for various lead-free solder materials such as Sn/Ag/Cu, Sn/Zn, Sn/Cu, with a tin slag oxidation rate of 0.8-2.0KG per 8 hours (depending on the size of the PCB board)

9. Add diversion channels and anti oxidation sleeves to reduce black powder and tofu residue like oxides.

10. The design of the tin furnace is reasonable, and the tin slag is automatically collected Cleaning the tin furnace is simple, convenient, and safe, without having to scoop up tin slag every day. It can be cleaned once a week or more depending on the situation.

The traditional peak machine tin furnace has a tin slag oxidation capacity of 5-8KG/8 hours. If the improved tin furnace is used to save at least 5KG of tin per day, the monthly savings are: 118 yuan * 5KG * 22 (days)=12980 yuan (calculated based on SnGu0.7) or 76 * 5KG * 22 (days)=8360 yuan (calculated based on 6337Sn), which is the price of one peak machine in a year.
