Structural design features of Guangshengde lead-free small double wave soldering machine GSD-WD300S

1. The special aluminum guide rail uses high temperature and wear resistance, and the special thermal compensation anti-deformation telescopic structure of the stainless steel guide rail ensures that the guide rail will not be deformed and will not fall off the board.

2. Three-point synchronous guide rail width adjustment device, worm wheel and worm heightening precision screw width adjustment, the width adjustment accuracy is less than 0.2mm, 6-point support, so that the guide rails are parallel and consistent, no size head, the entire guide rail installation, do not need to be cut off .

3. Guangshengde special 1.5mm double hook (no deformation, no tin sticking), thickness of the splint ≦2.5mm (the incoming board is a synchronous chain connection)

4. 90W imported frequency conversion motor is used for transportation, with overload force limiter protection device.

5. Imported high-quality micro anti-corrosion chemical pump, double-sided claw washing, propanol as cleaning agent, automatic cycle cleaning of chain claws

6. There is a thermocouple abnormal alarm function; the motor overload protection alarm, the head and the tail of the machine are equipped with two emergency emergency systems, please press it in special and emergency situations.

The characteristics of the control system of Guangshengde lead-free small double wave soldering machine GSD-WD300S

● Key-press control system, intuitive operation interface, PCBASE wave soldering control software V1.0 system independently developed by Guangshengde, which greatly improves work efficiency and reduces production costs;

● Fully automatic transportation power system, stepless frequency conversion speed regulation, automatic synchronization into the board, and the PCB board automatically enters the spray system.

The advantages of the welding system of Guangshengde lead-free small double wave soldering machine GSD-WD300S

1. The PCB board enters the soldering area of the tin furnace, and the soldering starts automatically, and the wave crest is automatically stopped after the soldering is completed.

2. Lead-free and environmentally friendly independent design of the tin furnace, lifting and in and out, convenient and safe, and easy to clean;

3. The tin furnace is made of high-quality imported stainless steel, and the aluminum silicate insulation material is insulated. When the temperature inside the furnace is 270°C, the temperature outside the furnace is ≤60°C, which has good insulation effect and high safety.

4. 3MM thick lead-free stainless steel material, high temperature and corrosion resistance, adapt to lead-free process, long life; a furnace is standard.

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

6. The tin furnace adopts imported high temperature motor, stepless frequency conversion speed regulation, independent control, stable peak performance;

7. The heating of the tin furnace adopts high-speed PID external heating type two-stage independent control, and the temperature rises rapidly, which solves the shortcomings of the tin furnace explosion;

8. The nozzle of the tin furnace can be adjusted according to the width of the PCB you want to pass, reducing the area of the ineffective soldering area, keeping the solder and air contact area to a minimum, and greatly reducing the amount of solder oxidation. The impurity of the tin bar is different from the tin dross. Suitable for various lead-free solders of Sn/Ag/Cu, Sn/Zn, Sn/Cu, and the oxidation amount of tin dross is within 0.8-2.0KG every 8 hours (depending on the size of the PCB board)

9. Increase diversion trough and anti-oxidation sleeve to reduce black powder and bean curd dregs oxide.

10. The design of the tin furnace is reasonable, and the tin slag is automatically collected. It is simple, convenient and safe to clean the tin furnace. It can be cleaned once a week or longer according to the situation without having to pick up the tin slag every day.

The oxidation amount of tin slag in the traditional wave crest machine tin furnace is 3-5KG/8 hours. If the improved tin furnace is used to save tin at least 2KG per day, the monthly savings: 118 yuan * 2KG * 22 (day) = 5192 yuan (Calculated by SnGu0.7) or 76*2KG*22 (day) = 3344 yuan (calculated by 6337Sn), the price of a wave crest machine in one year.
