Water-based flux is a new type of flux that has attracted much attention in the electronics manufacturing industry in recent years. This flux combines the excellent welding performance of rosin and the environmental protection characteristics of halogen-free, as well as the safety of water-based flux, providing a more reliable and environmentally friendly solution for the welding process of electronic products.1. Characteristics of rosin halogen-free fluxEnvironmental protection: Halogen-free flux meets the requirements of countries with strict environmental awareness for the prohibition of related halides, and the halogen (Cl, Br) content in its average is less than 900ppm, respectively, and the total is less than 1500ppm. This feature prevents the flux from releasing harmful substances during the welding process, which is more friendly to the environment and human health.Welding performance: As one of the main components of the flux, rosin has excellent welding performance. It can effectively remove oxides on the welding surface and improve the quality and reliability of the welding joint. At the same time, rosin halogen-free flux also has good wettability and fluidity, making the welding process smoother.Safety: Compared with traditional solvent-based flux, water-based flux has higher safety. It is non-flammable and non-explosive, reducing the risk of fire and explosion. At the same time, water-based flux does not produce harmful gases during use, which is more beneficial to the health of operators.2. Application advantages of rosin halogen-free water-based fluxImprove welding efficiency: Rosin halogen-free water-based flux can quickly remove oxides on the welding surface, improve the quality and reliability of the welding joint, thereby shortening the welding time and improving production efficiency.Reduce production costs: Because the flux has good welding performance and environmental protection characteristics, it can reduce the scrap rate and rework rate during the welding process and reduce production costs.Improve product competitiveness: With the continuous improvement of environmental awareness, more and more electronic product manufacturers have begun to pay attention to the environmental performance of flux. The use of rosin halogen-free water-based flux can improve the environmental performance of products, meet the market demand for green products, and thus enhance the competitiveness of products.3. Precautions for useStorage conditions: Rosin halogen-free water-based flux should be stored in a cool, dry, well-ventilated place, avoiding direct sunlight and high temperature.Shelf life: The flux may be contaminated or deteriorate during use, so its appearance and performance should be checked before use to ensure that it is used within the validity period.Operation specification: Operators should wear appropriate protective equipment, such as gloves, masks, etc., to avoid direct contact of the flux with the skin and eyes. At the same time, relevant operating procedures and safety regulations should be followed to ensure the safety and smooth progress of the welding process.In summary, rosin halogen-free, safer water-based flux has significant environmental protection, excellent welding performance and high safety, and is an indispensable new type of flux in the electronics manufacturing industry.
