Q: What are the different types of flux?

A: One of the oldest types of flux is based off of rosin. (Rosin is a refined and purified pine sap.) While rosin flux still exists today, it contains a blend of fluxes instead of just pure pine sap. This helps to optimize the flux and increase its performance and characteristics.

Q: What is flux and why do you need it?

A: Third, your flux should help to reduce and remove any surface metal oxides currently sitting on your metal surfaces. In certain cases, the flux that is typically included within the core of a solder wir e is good enough.

Q: What is the best soldering flux pen?

A: The SRA Soldering Flux Pen is great for quick jobs. Through the use of a pen-like device, the flux is easy to control and apply where you need it most. Unlike a loose paste, which can be messy and end up everywhere, the pen provides users with very little excess and targeted application potential.
