Is Soldering Paste the Same as Flux? Differences Explained for Electronics Engineers

Is soldering paste the same as flux? This technical article clarifies the differences for electronics engineers, covering their functionalities and practical implementations in both manual soldering (repairs, prototyping) and automated soldering (SMT reflow assembly) Soldering Paste Solder Rod Cleaning Introduction Is soldering paste the same as flux? This is a common question among electronics enthusiasts and students delving into PCB assembly and repair. These terms might seem similar because both are used in soldering processes and often come in syringes or jars. In reality, they serve different purposes and are used in different contexts of electronics manufacturing! Soldering Flux (often just called flux) is a chemical agent used to clean oxidation from metal […]
