Rosin paste flux is a type of flux used in soldering to clean and protect metal surfaces before they are joined. It is made from a mixture of rosin, which is a natural resin, and a solvent, which is usually alcohol. Rosin paste flux is applied to the metal surfaces to be joined using a brush or a cotton swab. It helps to remove oxides and other contaminants from the metal surfaces, which allows the solder to flow more easily and create a stronger joint.
Rosin paste flux is important for wire splicing because it helps to ensure a good electrical connection. Without flux, the solder would not be able to flow properly and create a strong joint. This could lead to a weak connection that could fail over time. Rosin paste flux also helps to prevent corrosion, which can damage the wire and lead to a loss of electrical conductivity.
