The so-called wave soldering refers to the use of the molten liquid solder to form a solder wave crest of a specific shape on the solder liquid surface with the help of the pump. and a certain immersion depth through the solder wave to achieve the process of solder joint welding. The machine used to achieve wave soldering is the wave soldering machine. Let me share what parts of the wave soldering machine generally consist of?
1. Wave soldering chassis: It is mainly the load-bearing frame of each component of the wave soldering equipment. The main frame here must be made of real materials, otherwise the wave soldering equipment will fall apart after a long time of use.
2. Transportation of wave soldering machine: Its main function is to clamp the PCB carrier in each process area of wave soldering at a certain speed and inclination angle.
3. The tin furnace of the wave soldering machine: it is a core component, and all other components are developed around the wave soldering furnace, which is to generate the specific liquid solder wave required by the wave soldering process.
4. Spray of wave soldering machine: The main function of this system is to apply flux evenly to the PCB.
5. The preheating system of the wave soldering machine: its function is to avoid the rapid heating of the PCB during soldering, the volatilization of the solvent in the flux and the activation of the active substances in the flux.
6. Welding system of wave soldering machine: The welding system is one of the most critical parts of the wave soldering machine and an important part of the completed soldering operation. The basic principle of wave soldering is to catch the stirring action of the pump in the solder tank to melt the molten liquid solder. Wave soldering of a specific shape is formed, and the PCB with the components inserted is placed on the conveyor belt, and the soldering is realized by passing through the solder wave at a specific angle and a certain immersion depth.
7. Clean the chain claws: clean the sundries on the chain claws of the wave soldering equipment.
8. Wave soldering machine into the board connection device: to ensure the smooth entry of the PCB from the plug-in body into the wave soldering transmission system.
9. Wave soldering cooling system: It is mainly responsible for reducing the damage of thermal energy to components and improving the bonding strength of copper foil on the PCB substrate.
10. Wave soldering electrical control system: It is the brain of the wave soldering equipment, and it is responsible for coordinating and managing the work of each component of the system throughout the operation of the equipment.
11. Air knife of wave soldering equipment: it is formed by cold air to form an air curtain effect, and hot air knife eliminates continuous welding.
12. Automatic tinning device for wave soldering equipment: it automatically replenishes the solder lost due to welding in time.
13. Nitrogen adding device: Nitrogen reduces solder oxidation and improves welding strength, etc. (Because nitrogen is expensive and time-consuming, there are currently fewer electronic product manufacturers using nitrogen wave soldering on the market).
But in general, the main components of the wave soldering machine are four parts: spray system, preheating system, transportation system, furnace system.
