Flux cleaning unit

A cleaning unit, in particular, a cleaning unit for removing flux by using a high-pressure high-temperature water jet flow, and the cleaning liquid can also be recycled and reused.

Flux is usually a mixture of rosin as a main component and is an auxiliary material to ensure the smooth progress of the welding process. Welding is the main process in electronic assembly. Flux is the auxiliary material used in soldering. The main function of flux is to remove the oxide and the oxide on the surface of the soldered base material, so that the metal surface can reach the necessary cleanliness and prevent the surface from soldering. The oxidation again reduces the surface tension of the solder, improves the soldering performance, and the performance of the flux directly affects the quality of the electronic product.

However, flux or oil stains can hinder the transmission of electronic component signals, so cleaning operations are often required to dissolve and remove flux or grease. Fluxes generally have two types of water-soluble fluxes and oil-soluble fluxes. Water-soluble fluxes are mostly washed directly with clean water, while oil-soluble fluxes are washed with a solvent to remove them. In addition, there is a cleaning operation by ultrasonic cleaning to remove flux or grease. Although it can effectively remove flux or grease, ultrasonic waves can damage electronic components and cause accelerated aging of electronic components.

However, the conventional technique uses the flushing method to remove the flux, because the water flow is difficult to concentrate on the surface of the electronic component, and the flushing water flow is insufficient, so it is difficult to remove the adhesive flux from the electronic component. Removal, in order to achieve the purpose of removing the flux, it is necessary to repeatedly rinse, thus causing the use of water or solvent to double, and the manufacturing cost is also increased. In addition, the rinsed clean water can not be recycled and reused because it has been mixed with flux or oil stains, and must be sent to the wastewater treatment plant, which not only increases the manufacturing cost, but also wastes water resources. If it is not properly disposed or leaked, it will It will affect the natural environment.

The main purpose of this creation is to provide a flux cleaning unit that includes a clear a washing device for spraying a cleaning liquid on an electronic component to remove a material to be removed on the electronic component; a liquid collecting tank disposed in the liquid collecting tank for receiving the mixture to be mixed a cleaning liquid for removing the object; a separating device connected to the lower side of the liquid collecting tank by a first pipe to receive the cleaning liquid discharged from the liquid collecting tank and mixed with the object to be removed, the object to be removed Naturally separated from the cleaning liquid, wherein the cleaning material is suspended above the cleaning liquid; a circulating liquid supply device receives the cleaning liquid from the separation device, and returns the cleaning liquid to the cleaning device for reuse.

The feature of this creation is that the cleaning device generates a high-pressure and high-temperature waterjet flow, and the high-pressure and high-temperature waterjet flow is directly sprayed on both sides of the electronic component, so that the cleaning device can clean the high-pressure hot water knife flow during cleaning. Effectively concentrated on the surface of the electronic component, and the high-pressure flushing hot water flow is strong and powerful, so that the adhesive flux can be effectively removed from both sides of the electronic component without damaging the surface of the electronic component. In turn, improve the quality and yield of electronic products.

Another feature of the present invention is that the liquid collecting tank sends the cleaning liquid collected by the cleaning liquid together with the cleaning liquid to the separating device for separation treatment, and the circulating liquid supply device further separates the cleaning. The liquid is supplied to the cleaning device for cleaning treatment, so that the cleaning liquid can be recycled and reused, thereby greatly reducing the amount of water or solvent, thereby greatly reducing the manufacturing cost and avoiding affecting the natural environment.

Preferably, the cleaning solution is water or other suitable liquid, and the object to be removed is flux, oil, grease or other foreign matter.

Thereby, when the cleaning liquid is ejected from the nozzles 111 of the two water jet devices 11, 13, a plurality of powerful high-pressure water jet flows are formed, and the high-pressure water jet flows directly to the electronic component. On both sides, the object to be removed on the electronic component is effectively removed. Preferably, the nozzles 111 are of a slit type or a slit type to form a plurality of powerful high-pressure water jet flows when the cleaning liquid is ejected from the nozzles 111 of the two water jet devices 11 and 13.
