Small wave soldering is also a reduced version of general large wave soldering. Its function is the same as that of large wave soldering, but its preheating zone is short and tin furnace is relatively small. It is only suitable for trial production of electronic products and small batch production of electronic products. Compared with the general wave soldering machine, the small wave soldering machine can save electricity and tin. There is a certain demand in the market. If the monthly production is not much, it is not cost-effective to buy the large wave soldering machine. There are also many manufacturers looking for the small wave soldering machine. GrandSeed wave soldering is here to share the parameters and system composition of the small wave soldering machine.

2、 System composition of small double wave soldering machine

The components of small wave soldering and large wave soldering are basically the same. Small wave soldering is also composed of control system, loading and transportation system, flux spraying system, preheating system, welding system and cooling system.

1. Control system of small double wave soldering machine

The control system of small double wave soldering machine is mainly based on keystroke control, intuitive operation interface, the PCBASE wave soldering control software V1.0 system developed by Guangsheng, automatic transportation power system, stepless frequency conversion, automatic synchronizing into the board, and PCB plate automatically entering the spray system.

2. Loading and transportation system of small double wave soldering machine

It is mainly composed of track, which can control the distance mechanically or electrically, and the welded PCB can run smoothly on the track.

3. Flux spraying system of small double wave soldering machine

The negative pressure generated by high-speed compressed air is used to extract the flux, and the flux is sprayed evenly on the PCB welding surface through a special nozzle.

4. Preheating system of small double wave soldering machine

The function of preheating system is to preheat the components of PCB. High temperature can make the solvent in the flux volatilize rapidly and activate the flux, so as to remove the oxide layer of PCB pad and components, and lay the foundation for high reliability welding.

5. Welding system of small double wave soldering machine

The welding system is one of the most important parts of the wave soldering machine. The basic principle of wave soldering is to take the stirring action of the pump in the solder tank, form the molten liquid solder into a specific shape of wave soldering, insert the PCB of the components into the conveyor belt, and pass through the solder wave through a specific angle and a certain immersion depth to realize the soldering.

6. Cooling system of small double wave soldering machine

The cooling system of small wave soldering is located at the end of the wave soldering. Generally, four small fans are used to blow cold air to the circuit board after wave soldering to eliminate the tin bonding phenomenon after wave soldering.
