Technological characteristics of Guangshengde energy-saving tin-free lead-free wave soldering furnace

1. How is the tin dross produced by wave soldering? High temperature tin exposed to the air will react with oxygen in the air to produce black powdery tin dross. The tin in wave soldering makes a large amount of high-temperature tin contact with air when the wave is rolling, which makes it easier to produce a large amount of tin dross. From Figure 1, you can see that our Guangshengde wave soldering furnace nozzle can be based on the PCB board you want. The width is adjusted to reduce the area of the ineffective welding area, keep the solder and air contact area to a minimum, and greatly reduce the amount of solder oxidation. The amount of tin dross oxidation is within 0.8-2.0KG every 8 hours (depending on the size of the PCB).

二、Guangshengde adds an anti-oxidation sleeve to the wave source generator of the wave soldering motor to reduce black powder and tofu-like oxides. The rotating shaft of the tin furnace wave generator motor on the market directly contacts the tin. When the rotating shaft rotates at a high speed, it will rub against the tin, which will produce a large amount of tin ash, which will cause the manufacturer to waste the cost of soldering. Our Guangshengde tin The furnace wave generator motor shaft has specially developed a new technology of "anti-oxidation sleeve" so that the motor shaft does not directly contact the solder, so that a large amount of tin dust is not generated, which saves customers the production cost.
